What Primer Should I Use on Exterior Wood?

Primer may be used with oil-based paints but work best with latex paints because they adhere more tightly to latex paint. They can be used on exterior wood, such as fences and decks. They are not as effective as oil-based paints in helping the paint adhere to the wood because they do not contain the same amount of solvents.

On concrete or masonry, use a sealer first, followed by a primer. Sealers adhere better to concrete than wood, keeping the concrete from absorbing the paint. If you paint a fence, you may consider using oil-based paint. Oil-based paints adhere better to fencing than latex paints, keeping the fencing from absorbing the paint.

Things to Consider before Buying a Primer for Exterior Wood

Things to Consider before Buying a Primer for Exterior Wood

Before going for the primer, you must set your purpose, i.e., to work on exterior wood. Now comes; what do you expect from the primer on exterior woods? 

There are many, like Odorless, hassle-free, easy to clean, and whatnot. We’ll be covering such factors that your primer must have to enact upon exterior woods. Trust us; they increase the longevity and quality by many folds. 


Odor is present in every paint or medium. Sometimes, when you apply them to the wall, they create a crazy environment in the surrounding. It becomes difficult to breathe amid the strong odor. 

This is where you should be selective. Pick an odorless primer that has little impact on the surrounding odor. You’ll be able to apply them easily on walls, but you’ll also be able to dwell in that place relentlessly. 


The paint will attach to your skin while applying or working with it. But that shouldn’t be a cause to attract problems. 

Pick the one that has 0 impact on skin damage. You might even have kids around. Think of the havoc it will create if it causes damage to them. 


This is where your primer defines how it looks from the outside. It is not only by the looks or color but also by its resistivity. 

Because the change of weather will continuously impact the wood constantly, the finishing will determine how perfectly the primer will resist those impacts and save the surface from them. 

Drying time

Drying time shouldn’t be an issue if you look for a good primer. There are a lot of primers that take the way a lot of time to dry up. If you use the primer for commercial purposes, you can go for a quick-drying one. After all, you need to the maximum in the minimum time. 

For home purposes, this shouldn’t be an issue. You can skip or compromise the factor if you get a good primer with all the other qualities you are looking for.

A primer that acts well against the air, sunlight, and weather change should be the top priority in this case. Most of the Time, primers cannot sustain for a long time on wood stairs, walls, etc., outside.  

This should be considered. The one making the strongest bond in those scenarios should be set at the top-most priority.
