Project Overview

If you’re painting a white set plaster wall, it’s important to seal it first. White set has lime products in it, which can burn the paint if the wall is not properly sealed. In just a few steps, we’ll show you how to prepare the sealer, cut in the wall’s edges, and seal the wall in just a few simple steps.

Step by Step Instructions

1 Prepare the sealer
2 Cut in the edges
3 Seal the wall
  • Step 1. Prepare the sealer

    First, put on your respirator mask because sealer fumes can be quite potent. Remove the can lid and mix the sealer thoroughly with a stirrer. Then pour the sealer into your bucket. 

  • Step 2. Cut in the edges

    Before you start sealing the walls with your roller, cut in the edges using a paintbrush. Cutting in is when you use a paintbrush to paint areas that are too narrow for rollers, like corners, ceiling lines, frames and skirting boards.

  • Step 3. Seal the wall

    Now, pour the sealer into your paint tray and apply to the wall with a roller. Once the wall is covered leave it to dry before painting. Now it’s ready for painting.
