By admin | Tools and Equipment

Many have been asking what could be the best primer for pressure-treated wood, for there are a lot of products available out there, but it’s best to know what products are effective, so as not to cost much money and time. So here are the best primers you could use, and are certainly effective Primers for pressure-treated wood.

Pressure-treated wood is a type of wood that is fortified with chemical preservatives to help protect the wood from rot and insects. A depressurized tank holds the wood inside, removes the air in the material, and replaces or infuses the wood with a preservative.

Even if the wood is already treated to enhance its durability, though weathering and corrosion is inevitable, and even treated wood should be properly prepared and painted.

Primers help prepare the wood or any surface for better paint adhesion, to prolong its durability, and keep it from being worn due to environmental interference, including molds, mildew, pests, and corrosion.

Since pressure-treated wood is mostly used outdoors, or in parts where there’s high humidity, the wood should be sealed to make it more durable, and endure the factors for the wood to rot.

Apart from that, the natural appearance of pressure-treated wood may not be as appealing to your preference, so it will come down to getting your wood painted, so your wood has to be primed, and picking the right primer can be a little tricky sometimes. Since there are a lot of products available out there, and one of the most frequently-asked questions is, what type of primer is the best for pressure-treated wood?

Latex-based primer is said to be the most suitable one to use for priming your pressure-treated wood, why? Because you’d need a light-weight, quick-drying, flexible, and durable to make the paint/topcoats to last. Oil-based primers are brittle and tend to make the paint or the primer prone to peeling and cracking, and this type of primer can protect and keep your paint last longer.

There are thousands of primers available for you to use, but we dug deeper in search of the best primers that you could use for your wood project; to help you save time and money not to undergo the ‘trial and error’ with other products. These primers were carefully selected to suit your needs, and give you best results.

Conclusion

Money and effort could go straight to waste if we didn’t choose and use the right product carefully; spending money from using one product to another until you find the most effective one, and that’s not good. There are millions of products available out there, but another thing you need to know is the material that you will paint - whether it’s ready to be primed or not. There goes the sanding, and cleaning of the wood and letting it dry; pressure-treated wood will not accept the primer, or will not absorb it properly, causing the paint to flake out.
