How to Cure Sheetrock Plaster Paint

Sheetrock is a type of plasterboard that commonly makes up walls for various types of structures. Plaster paint is a mixture of sand, cement and water that covers the plasterboard to help protect the surface. Once the plaster is dry, you can paint it whatever color you wish, just like any other wall surface. There are some conditions that can help the plaster paint you apply to the sheetrock cure more efficiently so that you have a sturdier surface once it's cured.

Hawk

Instructions

- 1
  Conduct the project on a day with relatively low humidity levels for your region, as plaster cures better with low humidity. Ensure the indoor temperature where you're installing the plaster is around 55 or 60 degrees Fahrenheit, as plaster paint cures better in this temperature range.
- 2
  Dip your trowel into a little bit of water and spread it over your hawk to prevent the plaster from sticking to the hawk.
- 3
  Apply plaster paint to the hawk with your trowel. The hawk holds a large amount of plaster while you apply smaller amounts to the wall.
- 4
  Scrape up some of the plaster from the hawk with the trowel, scooping from the bottom up.
- 5
  Place the trowel against the sheetrock at the bottom. Scrape upward with the plaster to spread it over the wall. Scrape back down again to spread the plaster evenly. Move the trowel up and down over the surface a few more times, as thinly spread plaster cures more evenly.
- 6
  Apply even pressure as you move the trowel up and down the wall. Again, an even coat cures better.
- 7
  Maintain the appropriate conditions within the space as much as possible while it cures.
