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. 

Drying alone can take 1 to 4 hours to dry to the touch per plaster layer, but some types of plaster take several hours longer to dry. However, this doesn’t mean the job is done because plaster doesn’t fully harden until it cures, which can take a few days to a couple of weeks. It may take even longer if you’re building a new, pretty thick plaster wall. Allow the plaster to cure before painting it.

Plaster walls typically last between 30 and 70 years, but depending on the quality of the materials and the moisture levels in the building, they can last for over 100 years. With expert application and consistent maintenance, plaster can even last for centuries. To extend its lifespan, it is important to have the plaster professionally installed, address any water damage promptly, and repair small cracks as they appear. Regular inspections by a professional can help identify and address concerning cracks before they become significant issues.

It may take a bit of patience and trial and error to match your particular drywall texture type when making repairs. For orange peel or knockdown finishes, use a spray texture product or a thinned joint compound applied with a roller or sponge. Practice on scrap drywall or cardboard first. Once dry, lightly sand and prime before painting.
