One of the most important steps in painting is using primer. Primer performs important functions. It seals the surface, blocks stains, and it covers very small imperfections depending upon application. The larger ones can be caught and fixed before you start painting that expensive color paint you bought. Because it seals the surface, the coverage of that expensive paint will come close to what it says on the can, and you may need only one good coat.
The photo on the left is Glidden Interior/Exterior Gripper Primer Sealer. I was turned on to this by the paint guy at the orange store while buying BEHR Premium exterior paint. This is the only primer you will ever need. This is a full bodied, solid color primer with incredible gap filling and coverage. This is one of those products that make me want to paint more stuff, and painting is not on the top of my list of things to do.
I experimented with primer/paint products and they just don’t get the job done. Most notable was the complete coverage of the inked mill marks on the lumber for the Fascia and Outdoor Table projects. Also the gap filling on weathered wood.
Here is your 411 heads up. Quality finishes require quality prep work. If you want stunning results in painting you will need to primer. Get over it. Painting is one of the things that you cannot get an ‘app’ for. So you might as well use the products that will give you the best results. Gripper is the primer I recommend. It is really that good.
P.S. Try not to get it on you. It sticks really well and is harder than hell to get off your skin.
