You’ve just had your home or a room replastered! Ready to rock and roll with the paint? Not quite – you need to ensure that it is properly prepared! Take these steps to prepare and seal the plaster so that you can get the colour finish that you need.

You’ll need:

  • Emulsion (for the mist coat)
  • Water
  • Dust sheet
  • Decorator’s tape
  • Topcoat paint
  • Paintbrush or roller

Allow the plaster to dry out

The first thing that is needed when painting new plaster, is to allow it to dry out completely. A week should usually be ample time for the damp patches to completely disappear. As soon as the plaster is dried out, it should be light without any dark spots and have a consistent colour and appearance throughout the entire wall.

The plaster will dry a lot faster with a heater, or by opening a window. If you try to apply paint to wet plaster, this can sometimes cause problems with adhesion. Adding emulsion to wet plaster also                            

Mix a mist coat

A mist coat is made from watered-down emulsion paint, and also acts as a primer. The additional moisture can give the wall something so that the topcoat can properly stick securely. Additionally, you can use a water-based primer. This saves you the mess of creating a mist coat. Additionally, primers are completely waterproof. They can help you to achieve an even and colourful coat.

Apply the mist coat and allow it to dry.

There are a couple of different ways that you can apply the mist coat. If you decide to use a roller, then you will cover the wall faster, but unfortunately, it could be quite messy – rollers splatter paint very easily indeed! Alternatively, a paintbrush may take a tad longer, but you will not have as many drips to deal with.

If you choose to apply the coat, then you can work in smooth upwards motions until the entire wall is covered. The mist coast can be very runny, so if you spot drips or streaks, paint over them quickly to prevent them from drying or ruining the ideal finish.

After doing the mist coat application, you should apply the topcoat.

Decorate with topcoat

Following on from the completion of the mist coat, you should feel comfortable decorating normally. There is no need to sand the wall down as you’ve already done the preparation.

Apply the topcoat in a V shapes motion, this will allow for even coverage. The best results will be yielded by more than one coat.
