How to use 3-in-1 Basecoat

Before you start

When using Ronseal's 3-in-1 Basecoat make sure your room is above 10°C and open a window to keep it ventilated. Cold weather can stop the paint from drying properly. Cover anything you don’t want to get paint over.
Get rid of any loose paint or plaster by giving it a quick sand. Wipe the area you’re going to paint with a damp cloth to make sure it’s clean and free from dust.


Give it a really good stir. Then use a roller or brush to put it on. It’ll be touch dry in 2 hours. Extra coats may be required when making dramatic colour changes. After 4 hours it’ll be ready to paint over.

Clean up

Take as much paint off your brush or roller as you can. Wash in warm soapy water.

Don’t empty leftover paint into drains or watercourses. Instead, contact your local authority, who may have particular ways to get rid of unused paint.
