How to Paint Older Sheetrock Walls
- 1). Dust the old Sheetrock with a coarse plastic brush or broom.
- 2). Cover areas adjacent to the old Sheetrock with blue painter's tape. Protect areas beneath the Sheetrock, using dropcloths.
- 3). Coat the old Sheetrock with latex primer, using a roller. Start on the left side of the wall and proceed to the right. Use a polyester brush to prime portions of the Sheetrock that prove inaccessible to your roller. Allow the primed Sheetrock to dry for at least two hours.
- 4). Wash your roller/brush with water.
- 5). Paint the Sheetrock just as you primed it. Allow the finish to dry for two full hours.
