Pengecatan yang baik telah membutuhkan persiapan-persiapan yang matang. Persiapan yang benar akan dapat membuat pekerjaan pengecatan lebih capat, mudah, dan biaya rendah, selain memberikan hasil akhir yang baik juga lapisan cat lebih tahan lama, selain pemilihan produk yang tepat.

Ada beberapa hal yang telah mempengaruhi keberhasilan pengecatan dinding tembok (bata), yang paling berpengaruh adalah kualitas atau mutu dinding itu sendiri (terlepas dari kualitas cat yang dipakai). Masalah yang sering timbul akibat dari kualitas dinding yang jelek biasanya adalah belang-belang seperti basah (bila kadar air dalam dinding terlalu tinggi), lapisan cat yang menggelembung, dll.

Sedangkan bila yang dipakai cat dinding dengan kualitas rendah maka masalah yang sering terjadi adalah pengapuran, warnanya luntur, dll. Bagaimana kita tahu cat yang kita pakai tersebut berkualitas?. Cat yang berkualitas minimal telah mempunyai empat fungsi yang harus dimiliki diantaranya daya sebar, daya tutup, mudah dalam pengaplikasiannya, dan aman bagi kesehatan lingkungan. Memang semakin tinggi kualitas cat, maka harganya pun juga akan semakin mahal, karena disamping keempat hal pokok diatas, cat yang berkualitas akan dapat memiliki nilai tambah seperti daya tahan terhadap cuaca, anti jamur, tidak memudar (anti fading), mudah dibersihkan (washable), dapat menutup retak rambut (cover hair line crack) serta tambahan pengharum (fragnance).

PROSES PERSIAPAN DINDING

Yang harus di lakukan untuk dapat memulai proses pengecetan adalah menyiapkan permukaan yang akan dicat. Pastikan permukaan dinding bersih dan kering untuk dapat mencegah terjadinya pengelupasan. Biasanya memakan waktu 28 hari agar reaksi pengerasan semen pada plesteran beton mengering dengan sempurna.

Setelah permukaan tembok sudah benar-benar kering, dan sebelum tembok di plamir, lapisi dulu tembok dengan Wall Sealer, guna untuk menetralisir PH semen agar sesuai dengan PH cat. Dengan wall sealer Cat tidak mudah mengelupas dan warna cat tidak akan berubah dari warna aslinya.Cat akan menjadi seperti kapur jika daya serap tembok masih bekerja, untuk itu tembok juga harus dilapisi dengan Wall Sealer, namun jika untuk alasan ekonomis anda dapat melarutkan satu sampai dua bungkus lem putih dalam satu galon air kemudian kuaskan pada tembok sebelum tembok di cat.

PROSES PLAMIR DAN CAT DASAR
Sebelum pengecatan dilakukan ada pekerjaan pendahuluan yaitu plamir dinding. Plamir dinding terdiri dari 3 bagian bahan, yang pertama adalah semen putih, lem putih, dan kalsium. Semua bahan tersebut telah mempunyai fungsi masing - masing.
Penggunaan kalium pada bahan plamir berfungsi sebagai penambah volum dari plamir dan memudahkan penghalusan, namun apabila terlalu banyak justru akan dapat menyebabkan cat yang nanti kita kerjakan menjadi kurang kuat. Sebagian kontraktor bangunan sudah tidak menggunakan kalium sebagai campuran plamir, kecuali pada pekerjaan yang memerlukan harga sangat hemat dan waktu penyelesaian yang relatif cepat.
Teknik melamir yang efektif adalah dengan menggunakan kapi besar atau bahan bekas dari pipa pvc yang dibuat kapi. Dengan mengoleskan pada arah vertikal di dinding kemudian untuk lapis selanjutnya pada arah horisontal, demikian seterusnya sampai dinding menjadi rata. Lapisan yang kedua haruslah menunggu lapisan yang pertama kering dahulu.
Penghalusan menggunakan amplas dengan arah memutar. Alat penghalus otomatis sebaik digunakan agar lebih cepat dalam pengerjaannya.
Setelah diplamir, dilakukan Pelapisan cat dasar atau alkali sealer. Sebelum dilakukan pengecatan dengan cat tembok aplikasikan terlebih dahulu cat dasar alkali sealer, yang berfungsi untuk memberikan lapisan dibawah cat tembok sehingga memperkecil kontak langsung dengan alkali tembok. Selain itu alkali sealer berfungsi memberikan lapisan warna putih sehingga dapat mempercepat penutupan warna cat tembok pada dinding. Alkali sealer berbeda dengan cat putih. Penggunaan cat putih sebagai dasaran pengecatan tidak akan menghindari kontak langsung alkali tembok dengan cat, tetapi hanya berfungsi membantu daya tutup cat tembok saja.


PROSES PENGECATAN DINDING
Proses pengecatan dinding dimulai ketika semua permukaan dinding telah terplamir , sudah dalam keadaan halus teramplas, dan sudah dilapisi dengan cat dasar.

Penggunaan rol memang sangat efektif ketika kita mengecat pada pada bidang dinding yang luas, namun apabila hendak merapikan pada sudut-sudut ruang tetaplah kuas yang digunakan. Sebenarnya dengan menggunakan kuas cat akan lebih terasa hemat karena tidak terlalu banyak yang lengket pada rol kita. Untuk hasil yang sempurna cat tembok jangan terlalu kental, encerkan dengan air 30-35 persen dari total berat cat.

Lapis demi lapis kita cat, cara yang paling cepat agar dinding lekas tertutup rata oleh cat adalah dengan cara bersilangan. Lapisan pertama vertikal atau horisontal, kemudian tunggu kering, lapisan yang kedua kebalikannya.Selang waktu antara setiap lapis harus cukup lama. Secara teoritis adalah 2-4 jam, tetap sebaikny minimal 8 jam atau semalam.

TIPS DAN TRIK DALAM PENGECATAN
1.      Kerjakan pengecatan pada siang hari.
2.      Mulai dari dekat jendela. menuju ke ruang dalam.
3.      Bila mengecat seluruh ruangan, kerjakanlah mulai dari langit-langit yang diteruskan ke dinding dekat kusen jendela, pintu-pintu, dan kemudian ke bagian bawah.
4.      Mengecat tiga lapis sesuai dengan anjuran pencampuran air lebih baik dari pada satu lapisan tebal, usahakan menyediakan cat yang cukup unluk area yang akan dicat dengan menghitung iuas area yang akan dicat, jangan mengecat pada suatu bidang yang lebar sekaligus. Batasi bidang pengecafan aniara satu sampai dua meter persegi sekali mengecat. Baru dilanjuttkan ke bidang berikutnya, Perhatikanlah petunjuk-petunjuk mudah pada kemasan cat sebelum bekerja.
5.      Lakukanlah pembuangan sisa saat melakukan pengecatan karena kita harus bertanggung jawab terhadap lingkungan dengan menghindarkan membuang limbah/sisa cat ke dalam saluran pembuangan.
6.      Terakhir adalah membiarkan sisa cat mengering di wadahnya sebelum dibuang ke tempat sampah.

Dengan mengikuti petunjuk-petunjuk sederhana tersebut pengecatan akan lebih mudah, menghemat waktu, uang dan tenaga. Karena, persiapan permukaan yang benar akan memberikan hasil akhir yang lebih baik dan perrnukaan yang dicatakan lebih tahan lama, jangan mencoba untuk mengecat satu lapisan dengan tebal.
 
Trik Penggunaan Aci Instan pengganti plamir dan cat dasar

Mengerjakan finishing din-ding semakin mudah dan cepat dengan aci instan. Warnanya yang putih dapat menggantikan dua proses finishing dinding.

Mari kita hitung berapa tahap dibutuhkan sebelum mengecat dinding. Setelah plesteran, dinding mesti diaci. Setelah itu diplamir dan diampelas agar permukaannya halus. Cat dasar perlu diaplikasikan agar cat dinding dapat menutup rata permukaan tanpa menyisakan belang di beberapa tempat. Setiap tahap membutuhkan waktu antara dua-lima hari agar hasil finishing din-ding sempurna.

Proses yang demikian lama dan melelahkan itu, ternyata dapat menjadi singkat dan praktis. Caranya, Anda bisa mensubs-titusi material sehingga dapat menghilang-kan dua tahap pengerjaan, yaitu proses plamir dan pengecatan dasar. Bagaimana caranya?"Dua proses itu bisa dihilangkan jika Anda menggunakan semen aci instan

Aci instan terbuat dari campuran filler, semen putih, kapur, dan zat aditif. Ini menjadikan aci instan dapat merekat erat pada segala permukaan dinding (beton dan plesteran). Daya lentur dan proses pengeringan yang perlahan-lahan menjadikan aci instan sebagai material yang tepat untuk mengurangi retak rambut.

Retak rambut itu bisa terjadi jika proses pengeringan semen berlangsung cepat. Aci instan mengering lebih lama. Dengan demikian, proses muai- susutnya pun lambat, sehingga retak-retak rambut itu berkurang.

Penggunaan aci instan dianjurkan dalam praktik sehari-hari. Meski harga material ini lebih mahal dari semen biasa, tapi sebetulnya bisa hemat. Jika dihitung total biayanya, penggunaan aci instan ini dapat menghemat waktu pengerjaan dan biaya pembangunan.

KPK PERIKSA KETUA PENGADILAN DAN KAPOLRES

Wayne Rooney mengaku bahwa karirnya bersama timnas Inggris akan "sia-sia" kecuali ia berhasil memenangkan Piala Dunia.

Rooney yang memiliki 82 caps bersama Three Lions, disebut-sebut sebagai salah satu pemain terbaik yang pernah bermain di timnas Inggris. Namun, penyerang Manchester United ini mengaku semua gelar pribadi tak akan ada apa-apanya bila gagal meraih trofi Piala Dunia.

"Aku bisa mengakhiri karir bersama Inggris dengan menjadi pencetak gol terbanyak dan mungkin juga pemegang caps terbanyak, tetapi jika tidak berhasil (memenangkan piala), maka itu sia-sia," ujarnya.

"Saya ingin medali sebagai pemenang Piala Dunia," tegasnya.

Penyerang berusia 27 tahun ini membidik putaran final Piala Dunia 2014 sebagai kesempatan untuk mewujudkan impiannya tersebut. Selain itu, mantan pemain Everton ini juga berpeluang menjadi top skor sepanjang masa Inggris. Kini, Rooney berada di posisi ke enam dengan koleksi 35 gol. Terpaut 14 gol dari Bobby Charlton yang berada di puncak. (met/dzi)

Rooney:Karir di timnas bakal sia-sia tanpa gelar Piala Dunia

Semua orang pasti sudah familiar dengan vitamin C. Vitamin C adalah salah satu vitamin paling penting yang dapat membantu manusia menjaga kebugaran dan menguatkan kekebalan tubuh. Namun tak hanya itu saja , baru-baru ini penelitian juga telah mengungkap bahwa vitamin C juga dapat untuk menurunkan risiko stroke.

Berdasarkan pertemuan tahunan pada American Academy of Neurology, peneliti telah mengungkap bahwa risiko hemorrhagic stroke (yang lebih mematikan, namun lebih arang terjadi dibandingkan stroke biasa) lebih rendah pada orang yang telah memenuhi kebutuhan vitamin C mereka.

"Penelitian kami telah menunjukkan bahwa kekurangan vitamin C bisa jadi salah satu faktor pemicu beberapa jenis stroke, sama seperti tekanan darah tinggi, kebiasaan minum alkohol, dan kelebihan berat badan," ungkap ketua peneliti Dr Stephane Vannier, M.D. dari Pontchaillou University Hospital di Prancis, seperti dilansir oleh Huffington Post (15/02).

Hasil ini juga telah ditemukan setelah peneliti mengamati tingkat vitamin C pada darah dari 65 partisipan yang telah mengalami hemorrhagic stroke, kemudian membandingkannya dengan kadar vitamin C dalam darah partisipan yang sehat. Mereka menemukan bahwa partisipan yang telah memiliki cukup vitamin C dalam darah mereka berkemungkinan lebih kecil untuk terkena stroke, dibandingkan dengan yang kekurangan vitamin C.

Sebelumnya, penelitian tahun 2008 di University of Cambridge juga telah menunjukkan bahwa orang yang memiliki tingkat vitamin C tinggi pada darah berisiko terkena stroke 42 persen lebih rendah dibandingkan dengan orang yang kekurangan vitamin C. Meski begitu peneliti telah menjelaskan bahwa penelitian lebih lanjut diperlukan untuk mengeksplorasi bagaimana cara vitamin C bisa menurunkan risiko stroke.

Berdasarkan National Institutes of Health, diketahui bahwa pria dewasa direkomendasikan mengonsumsi 90 miligram vitamin C sehari, sementara wanita dewasa membutuhkan sekitar 75 miligram vitamin C sehari. Vitamin C bisa didapatkan melalui beberapa makanan alami seperti jeruk, brokoli, dan paprika.

HOBART, Tasmania — Few places seem out of reach for China’s leader, Xi Jinping, who has traveled from European capitals to obscure Pacific and Caribbean islands in pursuit of his nation’s strategic interests.

So perhaps it was not surprising when he turned up last fall in this city on the edge of the Southern Ocean to put down a long-distance marker in another faraway region, Antarctica, 2,000 miles south of this Australian port.

Standing on the deck of an icebreaker that ferries Chinese scientists from this last stop before the frozen continent, Mr. Xi pledged that China would continue to expand in one of the few places on earth that remain unexploited by humans.

He signed a five-year accord with the Australian government that allows Chinese vessels and, in the future, aircraft to resupply for fuel and food before heading south. That will help secure easier access to a region that is believed to have vast oil and mineral resources; huge quantities of high-protein sea life; and for times of possible future dire need, fresh water contained in icebergs.

It was not until 1985, about seven decades after Robert Scott and Roald Amundsen raced to the South Pole, that a team representing Beijing hoisted the Chinese flag over the nation’s first Antarctic research base, the Great Wall Station on King George Island.

But now China seems determined to catch up. As it has bolstered spending on Antarctic research, and as the early explorers, especially the United States and Australia, confront stagnant budgets, there is growing concern about its intentions.

China’s operations on the continent — it opened its fourth research station last year, chose a site for a fifth, and is investing in a second icebreaker and new ice-capable planes and helicopters — are already the fastest growing of the 52 signatories to the Antarctic Treaty. That gentlemen’s agreement reached in 1959 bans military activity on the continent and aims to preserve it as one of the world’s last wildernesses; a related pact prohibits mining.

But Mr. Xi’s visit was another sign that China is positioning itself to take advantage of the continent’s resource potential when the treaty expires in 2048 — or in the event that it is ripped up before, Chinese and Australian experts say.

“So far, our research is natural-science based, but we know there is more and more concern about resource security,” said Yang Huigen, director general of the Polar Research Institute of China, who accompanied Mr. Xi last November on his visit to Hobart and stood with him on the icebreaker, Xue Long, or Snow Dragon.

With that in mind, the polar institute recently opened a new division devoted to the study of resources, law, geopolitics and governance in Antarctica and the Arctic, Mr. Yang said.

Australia, a strategic ally of the United States that has strong economic relations with China, is watching China’s buildup in the Antarctic with a mix of gratitude — China’s presence offers support for Australia’s Antarctic science program, which is short of cash — and wariness.

“We should have no illusions about the deeper agenda — one that has not even been agreed to by Chinese scientists but is driven by Xi, and most likely his successors,” said Peter Jennings, executive director of the Australian Strategic Policy Institute and a former senior official in the Australian Department of Defense.

“This is part of a broader pattern of a mercantilist approach all around the world,” Mr. Jennings added. “A big driver of Chinese policy is to secure long-term energy supply and food supply.”

That approach was evident last month when a large Chinese agriculture enterprise announced an expansion of its fishing operations around Antarctica to catch more krill — small, protein-rich crustaceans that are abundant in Antarctic waters.

“The Antarctic is a treasure house for all human beings, and China should go there and share,” Liu Shenli, the chairman of the China National Agricultural Development Group, told China Daily, a state-owned newspaper. China would aim to fish up to two million tons of krill a year, he said, a substantial increase from what it currently harvests.

Because sovereignty over Antarctica is unclear, nations have sought to strengthen their claims over the ice-covered land by building research bases and naming geographic features. China’s fifth station will put it within reach of the six American facilities, and ahead of Australia’s three.

Chinese mappers have also given Chinese names to more than 300 sites, compared with the thousands of locations on the continent with English names.

In the unspoken competition for Antarctica’s future, scientific achievement can also translate into influence. Chinese scientists are driving to be the first to drill and recover an ice core containing tiny air bubbles that provide a record of climate change stretching as far back as 1.5 million years. It is an expensive and delicate effort at which others, including the European Union and Australia, have failed.

In a breakthrough a decade ago, European scientists extracted an ice core nearly two miles long that revealed 800,000 years of climate history. But finding an ice core going back further would allow scientists to examine a change in the earth’s climate cycles believed to have occurred 900,000 to 1.2 million years ago.

China is betting it has found the best location to drill, at an area called Dome A, or Dome Argus, the highest point on the East Antarctic Ice Sheet. Though it is considered one of the coldest places on the planet, with temperatures of 130 degrees below zero Fahrenheit, a Chinese expedition explored the area in 2005 and established a research station in 2009.

“The international community has drilled in lots of places, but no luck so far,” said Xiao Cunde, a member of the first party to reach the site and the deputy director of the Institute for Climate Change at the Chinese Academy of Meteorological Sciences. “We think at Dome A we will have a straight shot at the one-million-year ice core.”

Mr. Xiao said China had already begun drilling and hoped to find what scientists are looking for in four to five years.

To support its Antarctic aspirations, China is building a sophisticated $300 million icebreaker that is expected to be ready in a few years, said Xia Limin, deputy director of the Chinese Arctic and Antarctic Administration in Beijing. It has also bought a high-tech fixed-wing aircraft, outfitted in the United States, for taking sensitive scientific soundings from the ice.

China has chosen the site for its fifth research station at Inexpressible Island, named by a group of British explorers who were stranded at the desolate site in 1912 and survived the winter by excavating a small ice cave.

Mr. Xia said the inhospitable spot was ideal because China did not have a presence in that part of Antarctica, and because the rocky site did not have much snow, making it relatively cheap to build there.

Anne-Marie Brady, a professor of political science at the University of Canterbury in New Zealand and the author of a soon-to-be-released book, “China as a Polar Great Power,” said Chinese scientists also believed they had a good chance of finding mineral and energy resources near the site.

“China is playing a long game in Antarctica and keeping other states guessing about its true intentions and interests are part of its poker hand,” she said. But she noted that China’s interest in finding minerals was presented “loud and clear to domestic audiences” as the main reason it was investing in Antarctica.

Because commercial drilling is banned, estimates of energy and mineral resources in Antarctica rely on remote sensing data and comparisons with similar geological environments elsewhere, said Millard F. Coffin, executive director of the Institute for Marine and Antarctic Studies in Hobart.

But the difficulty of extraction in such severe conditions and uncertainty about future commodity prices make it unlikely that China or any country would defy the ban on mining anytime soon.

Tourism, however, is already booming. Travelers from China are still a relatively small contingent in the Antarctic compared with the more than 13,000 Americans who visited in 2013, and as yet there are no licensed Chinese tour operators.

But that is about to change, said Anthony Bergin, deputy director of the Australian Strategic Policy Institute. “I understand very soon there will be Chinese tourists on Chinese vessels with all-Chinese crew in the Antarctic,” he said.

WASHINGTON — During a training course on defending against knife attacks, a young Salt Lake City police officer asked a question: “How close can somebody get to me before I’m justified in using deadly force?”

Dennis Tueller, the instructor in that class more than three decades ago, decided to find out. In the fall of 1982, he performed a rudimentary series of tests and concluded that an armed attacker who bolted toward an officer could clear 21 feet in the time it took most officers to draw, aim and fire their weapon.

The next spring, Mr. Tueller published his findings in SWAT magazine and transformed police training in the United States. The “21-foot rule” became dogma. It has been taught in police academies around the country, accepted by courts and cited by officers to justify countless shootings, including recent episodes involving a homeless woodcarver in Seattle and a schizophrenic woman in San Francisco.

Now, amid the largest national debate over policing since the 1991 beating of Rodney King in Los Angeles, a small but vocal set of law enforcement officials are calling for a rethinking of the 21-foot rule and other axioms that have emphasized how to use force, not how to avoid it. Several big-city police departments are already re-examining when officers should chase people or draw their guns and when they should back away, wait or try to defuse the situation

Fatal Police Shootings: Accounts Since Ferguson

BEIJING (AP) — The head of Taiwan's Nationalists reaffirmed the party's support for eventual unification with the mainland when he met Monday with Chinese President Xi Jinping as part of continuing rapprochement between the former bitter enemies.

Nationalist Party Chairman Eric Chu, a likely presidential candidate next year, also affirmed Taiwan's desire to join the proposed Chinese-led Asian Infrastructure Investment Bank during the meeting in Beijing. China claims Taiwan as its own territory and doesn't want the island to join using a name that might imply it is an independent country.

Chu's comments during his meeting with Xi were carried live on Hong Kong-based broadcaster Phoenix Television.

The Nationalists were driven to Taiwan by Mao Zedong's Communists during the Chinese civil war in 1949, leading to decades of hostility between the sides. Chu, who took over as party leader in January, is the third Nationalist chairman to visit the mainland and the first since 2009.

Relations between the communist-ruled mainland and the self-governing democratic island of Taiwan began to warm in the 1990s, partly out of their common opposition to Taiwan's formal independence from China, a position advocated by the island's Democratic Progressive Party.

Despite increasingly close economic ties, the prospect of political unification has grown increasingly unpopular on Taiwan, especially with younger voters. Opposition to the Nationalists' pro-China policies was seen as a driver behind heavy local electoral defeats for the party last year that led to Taiwanese President Ma Ying-jeou resigning as party chairman.

Even as a high school student, Dave Goldberg was urging female classmates to speak up. As a young dot-com executive, he had one girlfriend after another, but fell hard for a driven friend named Sheryl Sandberg, pining after her for years. After they wed, Mr. Goldberg pushed her to negotiate hard for high compensation and arranged his schedule so that he could be home with their children when she was traveling for work.

Mr. Goldberg, who died unexpectedly on Friday, was a genial, 47-year-old Silicon Valley entrepreneur who built his latest company, SurveyMonkey, from a modest enterprise to one recently valued by investors at $2 billion. But he was also perhaps the signature male feminist of his era: the first major chief executive in memory to spur his wife to become as successful in business as he was, and an essential figure in “Lean In,” Ms. Sandberg’s blockbuster guide to female achievement.

Over the weekend, even strangers were shocked at his death, both because of his relatively young age and because they knew of him as the living, breathing, car-pooling center of a new philosophy of two-career marriage.

“They were very much the role models for what this next generation wants to grapple with,” said Debora L. Spar, the president of Barnard College. In a 2011 commencement speech there, Ms. Sandberg told the graduates that whom they married would be their most important career decision.

In the play “The Heidi Chronicles,” revived on Broadway this spring, a male character who is the founder of a media company says that “I don’t want to come home to an A-plus,” explaining that his ambitions require him to marry an unthreatening helpmeet. Mr. Goldberg grew up to hold the opposite view, starting with his upbringing in progressive Minneapolis circles where “there was woman power in every aspect of our lives,” Jeffrey Dachis, a childhood friend, said in an interview.

The Goldberg parents read “The Feminine Mystique” together — in fact, Mr. Goldberg’s father introduced it to his wife, according to Ms. Sandberg’s book. In 1976, Paula Goldberg helped found a nonprofit to aid children with disabilities. Her husband, Mel, a law professor who taught at night, made the family breakfast at home.

Later, when Dave Goldberg was in high school and his prom date, Jill Chessen, stayed silent in a politics class, he chastised her afterward. He said, “You need to speak up,” Ms. Chessen recalled in an interview. “They need to hear your voice.”

Years later, when Karin Gilford, an early employee at Launch Media, Mr. Goldberg’s digital music company, became a mother, he knew exactly what to do. He kept giving her challenging assignments, she recalled, but also let her work from home one day a week. After Yahoo acquired Launch, Mr. Goldberg became known for distributing roses to all the women in the office on Valentine’s Day.

Ms. Sandberg, who often describes herself as bossy-in-a-good-way, enchanted him when they became friendly in the mid-1990s. He “was smitten with her,” Ms. Chessen remembered. Ms. Sandberg was dating someone else, but Mr. Goldberg still hung around, even helping her and her then-boyfriend move, recalled Bob Roback, a friend and co-founder of Launch. When they finally married in 2004, friends remember thinking how similar the two were, and that the qualities that might have made Ms. Sandberg intimidating to some men drew Mr. Goldberg to her even more.

Over the next decade, Mr. Goldberg and Ms. Sandberg pioneered new ways of capturing information online, had a son and then a daughter, became immensely wealthy, and hashed out their who-does-what-in-this-marriage issues. Mr. Goldberg’s commute from the Bay Area to Los Angeles became a strain, so he relocated, later joking that he “lost the coin flip” of where they would live. He paid the bills, she planned the birthday parties, and both often left their offices at 5:30 so they could eat dinner with their children before resuming work afterward.

Friends in Silicon Valley say they were careful to conduct their careers separately, politely refusing when outsiders would ask one about the other’s work: Ms. Sandberg’s role building Facebook into an information and advertising powerhouse, and Mr. Goldberg at SurveyMonkey, which made polling faster and cheaper. But privately, their work was intertwined. He often began statements to his team with the phrase “Well, Sheryl said” sharing her business advice. He counseled her, too, starting with her salary negotiations with Mark Zuckerberg.

“I wanted Mark to really feel he stretched to get Sheryl, because she was worth it,” Mr. Goldberg explained in a 2013 “60 Minutes” interview, his Minnesota accent and his smile intact as he offered a rare peek of the intersection of marriage and money at the top of corporate life.

 

 

While his wife grew increasingly outspoken about women’s advancement, Mr. Goldberg quietly advised the men in the office on family and partnership matters, an associate said. Six out of 16 members of SurveyMonkey’s management team are female, an almost unheard-of ratio among Silicon Valley “unicorns,” or companies valued at over $1 billion.

When Mellody Hobson, a friend and finance executive, wrote a chapter of “Lean In” about women of color for the college edition of the book, Mr. Goldberg gave her feedback on the draft, a clue to his deep involvement. He joked with Ms. Hobson that she was too long-winded, like Ms. Sandberg, but aside from that, he said he loved the chapter, she said in an interview.

By then, Mr. Goldberg was a figure of fascination who inspired a “where can I get one of those?” reaction among many of the women who had read the best seller “Lean In.” Some lamented that Ms. Sandberg’s advice hinged too much on marrying a Dave Goldberg, who was humble enough to plan around his wife, attentive enough to worry about which shoes his young daughter would wear, and rich enough to help pay for the help that made the family’s balancing act manageable.

Now that he is gone, and Ms. Sandberg goes from being half of a celebrated partnership to perhaps the business world’s most prominent single mother, the pages of “Lean In” carry a new sting of loss.

“We are never at 50-50 at any given moment — perfect equality is hard to define or sustain — but we allow the pendulum to swing back and forth between us,” she wrote in 2013, adding that they were looking forward to raising teenagers together.

“Fortunately, I have Dave to figure it out with me,” she wrote.
