Frequently asked questions
How much does a litre of paint cover?
Around 12 square metres per coat for most emulsions, though textured walls and bold colour changes soak up more. Check the tin, as coverage varies by product.
How many coats do I need?
Two coats is standard for a solid, even finish. You may need three when going from dark to light, or when using strong colours.
