Everything you need to know about using a paint primer

What is paint primer?

So, what exactly is a paint primer? Simply put, it’s a primer used to prepare a surface for painting. It’s a specially formulated paint product that helps a new coat of paint adhere to the prepared surface. Primer can also extend the life of your paint.

Why should you use primer before painting?

Priming the surface you want to paint is incredibly important. It will help the paint adhere to the surface and protect your chosen finish. If you are painting wood, applying a primer can help seal the wood, which is naturally porous. It can also help prevent darker colors or any imperfections from bleeding through.

When to use?

There are a few basic rules to follow to help you decide if you need to use a primer. All of the following materials and surfaces require a primer before painting.

Bare wood – should always have a top quality finish applied. This is because the wood is incredibly porous and needs to be “sealed”.

Drywall with skim coating – adding a coat of primer will not only create a smooth surface, but will also protect this highly porous material before painting.

A shiny surface – paint will not adhere well to a glossy surface. You will need to lightly sand the surface and apply a paint primer.

When the surface is a dark color – applying two coats of white primer will allow you to add your lighter paint color. You will also save money on paint since you will need less paint.

The golden rule is, if in doubt, always use a primer.

What type of primer should be used for different projects?

It’s important to apply the right type of primer for your specific project. Below, we share the different types of primers available and when to use them for your home or office project.
