Do I need one or two coats of paint?

When you set about painting a room, two coats of paint is almost always required. While there are certain acrylic-latex blends that claim to only need a single coat, two coats will usually produce a much better end result. However, this rule can vary depending on the current colour of the walls, and the colour you’re planning to paint over it. Here, we’ve listed some handy advice for different painting situations.

Painting over the same or a similar paint colour

When you’re painting over an already-painted wall with the same or a similar paint colour, then there’s generally no need to prime the paint that’s already there. However, it’s still important to prepare the wall properly. Wash it to ensure you’re not painting over any grease, and fill in any cracks or holes, sanding down the filler before you start painting. Finally, make sure you’re painting with good lighting, as this will make it easy to see where you’ve already painted, and which areas still need attention. Two coats of paint is advisable, unless you’re using a colour that’s exactly the same.

Painting a dark colour over a lighter colour

When painting a dark colour over a lighter colour, your job is going to be slightly easier. Though it can depend on the specific colours used, you can use a single coat to paint a dark colour over a light colour in many situations. Just make sure you’re priming the wall with a grey primer first. This will ensure better adhesion to the wall, and stop little flakes of paint falling away. When there’s a lighter coat underneath, these seemingly small issues can be a huge eyesore!

Painting a light colour over a dark colour

When you’re painting a light colour over a dark colour, as opposed to the other way around, it’s advised that you use a coat of white primer, rather than grey. This will ensure that after the job’s done, there’ll be no noticeable places where the base colour shows through. When re-loading your paint roller, be sure keep it on the slanted part of the tray to let some of the paint roll off, as roller lines are more noticeable in a light colour. Apply one coat and let it dry, before checking for any areas where you can still see the base colour, and applying another coat.

How using a primer affects how many coats of paint you need

A coat of primer creates a surface that’s easy for a coat of paint to stick to. If you apply coats of paint directly onto many materials, it can cause the paint to flake and chip away easily. Without a primer, you may need to apply more coats of paint to get a good result.

How the quality of the paint affects how many coats of paint you need

The main thing that separates high-quality paint from low-quality alternatives is that high-quality paints last longer. When you shop around and choose a high quality of paint, individual coats will last much longer, and you’ll need to apply less of them.
