How to paint interior brick walls

20th July 2020

Interior brick walls can be a stunning feature in a home, especially if you’re lucky enough to live in a period property with exposed original brick work. In some houses however, brick walls can overwhelm a room and appear somewhat dated. One of the simplest, most transformative things you can do to update an interior brick wall is to paint it…

If you’re planning to paint your interior brick walls, it can be confusing to know what type of paint to use. Should you use a masonry paint or an interior emulsion? What about primers and top coats? If you’re unsure where to start, read on for our top tips to make painting interior bricks a breeze!

  1. Before painting your brick walls

Before you apply any paint, check that your bricks are sound and secure. Any loose or flaking material should be removed and mortar repaired. If the brick wall is old (for example, if you live in a period property) you might want to consider a lime based mortar.

If the bricks are dusty to touch, you should consider using something to stabilise them prior to painting. Our Wall Glaze is a breathable glaze designed to ‘bind’ the surface of the bricks and prevent dustiness. It’s especially suitable in older houses where the bricks still need to breathe.

  1. Using a stain blocker

If there are any signs of staining on the bricks, a stain blocker will prevent this from bleeding through. It isn’t always necessary, but if that’s the case on your interior brick wall, use our Isolating Primer – just on the dry stains – to ensure your paint has a perfect finish.

  1. Which paint finish to use on interior brick walls?

We’re often asked which paint finish is best for interior brick walls. While we have a couple of paints within the Earthborn range that would be perfectly suitable, we’d always recommend using our Claypaint.

Whereas our Ecopro Silicate Masonry Paint is ideal for exterior brick walls, its two part system forms a strong chemical bond with the masonry, so isn’t really necessary for interior bricks. Claypaint on the other hand, is a thick, creamy paint that’s very easy to apply. Its high clay content ensures great coverage and high breathability, with a flattering, super matt finish.

As bricks are more textured than plain plastered walls, it’s often easier to apply the Claypaint with a brush. Diluting the first coat with up to 2 parts water to 8 parts paint will help achieve a consistent finish. Apply one further undiluted coat for full coverage.

  1. What about a top coat?

Claypaint doesn’t require a top coat, but if you feel that your painted bricks need to be a bit more hardwearing, you can also use a watered down coat of Wall Glaze as a protective finish.
