Factors to Consider When Choosing
Pressure-treated lumber goes through a special treatment that makes it less likely to damage, thus increasing its durability and preventing insect infestation or mold growth.
Here is what you should consider when browsing for pressure treated wood primers:
1. Type of Material the Primer is Made From
Primers are all different from each other, so they contain different substances and formulas. Each one has its own benefits.
When it comes to priming pressure-treated wood, though, you have to be exceptionally careful when choosing your primer. Some primer materials may be better than others.
- Oil-based primers may resist the surface sometimes and it’s not ideal. Here’s a guide on when to use oil based primers on wood.
- Water-based primers may work better, and they dry fast as well.
However, experts claim that latex-based primers are the best ones to use on pressure-treated wood.
Your safety is the most important thing, and you need to consider it even when priming wood and painting it. This is why you should look into a primer that doesn’t contain too many dangerous chemicals. You should buy a primer for pressure treated lumber with a low odor and fewer VOCs.
The performance of the primer is critical. It has to perform very well on interior and exterior surfaces, especially outdoors.
A good primer that can perform well has three distinct qualities:
- Easy to apply
- Resists weather conditions
- Slow deterioration rate
Make sure you pick something with great performance on pressure-treated wood and something that covers stains and offers an even surface.
4. Pressure Treated Wood Finish
Your primer should offer a nice finish that will allow the color you apply on top to look as vibrant as possible. You should look for something that can apply an even coat that doesn’t make brush strokes visible.
Most primers are not that expensive, but some can reach high prices. Ideally, stick to something that has a good price-quality ratio. Don’t go for the cheapest products because they might not be the best out there.
Do I Need to Prime Pressure Treated Wood Before Painting?
Wood needs to be primed properly for the paint to adhere to the surface. And this applies to pressure-treated wood as well. This type of wood is often stripped of a lot of its moisture, which is why paint may not stick properly.
As a result, if you don’t apply a primer, the paint may start to peel. This will cost you a lot of resources, such as time and money.
If the pressure-treated wood has been primed beforehand, you might not require another layer of primer. However, if you see imperfections on the surface, you may want to consider priming.
Pressure-treated wood can also be very porous, which can cause the paint to look uneven. This is why you need to prime the surface so that the result looks flawless.
How to Prime and Paint Pressure Treated Wood
Pressure-treated wood needs to be completely dry before you attempt to prime and paint it. Usually, pressure-treated wood needs about 3-4 months to cure
Pressure-treated wood should not be painted in humid conditions. Therefore, you must wait until the weather is warm and sunny. Try waiting at least one month after the last rain or snow before attempting to paint it.
Once you’re sure the wood is dry and it can accept the coats, here is how to prime and paint your treated wood:
- Choose the right primer and paint. A water-based or latex primer is the best for pressure-treated wood. As for paints, you should go for either an oil-based polyurethane or a water-based one.
- Clean the treated wood.
- Apply the primer evenly on the surface.
- Allow the primer to dry by following this primer drying time guideline.
- If the primer settles, you can start applying the paint. Apply at least two coats to obtain a nice-looking surface.
How do You Prepare Pressure-Treated Wood for Painting?
Before painting your pressure-treated wood, it’s essential to clean the surface first. Take a brush with stiff bristles and grab some soap and water. The soapy water will clean the treated wood and get it ready for the paint job.
Make sure to rinse the surface first and allow it some time to dry. Also, if the wood just underwent treatment recently, you should let it dry completely first and then apply two coats of primer.
What Happens if You Paint Treated Wood Too Soon?
If you don’t let the treated wood dry before staining or painting it, it will damage the wood and your paint job.
This is because the paint will trap water in the wood. Later on, your paint will peel off, whereas the wood will start warping. This is why it’s always important to let pressure-treated wood dry before staining or painting it.
