"Great company to work with. Came when that said they would. Very clean while working and made sure the house was kept clean,too. Did the job blowing in insulation in our attic and showed me pics of it afterward. My house, in June was crawling to 87 degrees quickly in late morning, even though we had the AC set at 72. After"

Drywall Insulation questions, answered by experts

This depends on how much plaster is applied and in how many layers, but a decent estimate is around 150 square feet. If you are applying only two coats on a small wall, there is a chance you may only need one or two gallons for the entire project. If you are plastering a large living room wall with high ceilings, using one of the more involved techniques–like Scagliola–that requires several coats, expect the project materials costs to add up quickly. 

You should leave a gap between drywall sheets because they naturally expand and contract along with the building framing as temperature and humidity change. Most pro drywall installers leave a gap of about ⅛ inch between drywall sheets, allowing the sheets to expand, contract, and shift without cracking or becoming damaged. If you don’t leave enough gaps between slabs, the edges will press against each other when they expand, and the pressure can cause visible cracks.

It’s not a good idea to plaster over broken plaster (unless by broken you’re referring to cracked, in which case that’s perfectly fine). However, broken plaster can be a sign of a larger underlying issue like foundation damage or severe damage to the lath holding up the plaster, so it’s worth investigating before you simply plaster on top of the damage.

Yes, drywall can hold a 50-pound TV. However, when mounting a TV, you’ll either need to attach it to wall studs or use drywall anchors. If you use anchors, make sure to buy a type that can hold at least 50 pounds. Molly bolts, threaded anchors, and toggle bolts are all good options. For extra support, you can also install a wall mounting plate with the anchors.

The short answer is yes, a sagging plaster ceiling is dangerous. Sagging plaster on a wall is something you should fix immediately, but it isn’t a major concern. If the same type of sagging occurs on a ceiling, however, you could be in danger of your ceiling falling in large chunks. When plaster sags, it loses its strength and ability to hold itself up. The bonds that hold it together are strong, though, so if a sagging area falls, it will take large pieces down with it.
