To Prime or Not to Prime
Paint stores encourage their consumers to use a primer under the top coat of paint. This makes them a lot of money of course, but is not the best advice. When someone wants to use primer, they only think of two different capabilities – priming and sealing. In reality, primer is about two different applications and probably two different products.
- A sealer is meant to ‘seal’ something into the wall, like water stains or ink from a pen. Have you ever tried to paint over a pen mark on the wall? If so, you probably noticed that the ink bled right through the paint you just put on. Then you paint it again, and the same thing happens – you still see the ink. A sealer will fix this. The sealer will seal the ink into the wall and not allow it to bleed through the finish coat of paint. You will notice that the ink will bleed through the sealer, but that’s fine because you will still need to apply the top coat. Once that is done, you will never know that there was ink on the wall.
- A primer does something a little different. It primes the surface to make it ready for the top coat. For example, you need to prime raw wood for the top coat to stick to it. There are three main substrates that need priming – raw wood, new drywall, and raw metal. Some paints have a primer built into it and you may be able to use it as a primer and a top coat all at once. But most of the time, you will have to prime these substrates before applying your latex topcoat.
Remember this rule – If the substrate is already painted, you DON’T NEED a primer anymore. You may need a sealer if there are pen marks or a water stain, but not a primer.
