DIY Guide: How to Plaster a Wall

Builder Mike Griggs shows you how to plaster a wall in this step-by-step guide. 

As with most DIY jobs, it’s all about preparation. Clean the area off before getting started, including any dags around the edges, which can be removed with a knife.

The perfect plaster consistency is just a touch stiffer than toothpaste – it shouldn’t be falling off the trowel. Add water a little at a time while mixing it up and make sure the texture is consistent throughout.

1. You may want to put gauze on the wall to stop the plaster falling through.

2. Use a base coat. There are two kinds – 45 minutes or 60 minutes drying. Let the base coat dry fully before coming back for the final coat.

3. Spread on evenly with a trowel and be sure to cover your edges. Leave to dry overnight before coming back to sand and paint.
