Painting pressure treated wood need to be done in a proper way in order to make the paint last longer. I’ve never painted brand spanking new treated exterior plywood and I have a new customer that wants me to cut out lettering for her business. I used treated 4x4x8s and have never had a problem – attached the boards to them with decking screws but don’t remember how long they were. It is therefore very important to apply a preservative to pressure treated wood to slow down the drying as a way to inhibit shrinkage. If I were going to paint” them I think I would use a colored stain that is marketed for deck boards.
It’s less maintenance if you stain it rather than paint it — but if you want longevity with little to no maintenance, consider another material. If you are putting up a lot of fencing you should be able to buy from my one of my suppliers and have it shipped for around the same cost as deck boards. The exception to this is wood that comes pre-treated with a wax finish or sealer.
This season, try this test to find out if your deck needs re-finishing: Sprinkle a few drops of water on the wood. To be fair, there was one government study that did not find any more toxicity in the smoke from pressure-treated wood than from regular wood. Any preservative that is applied needs to be a type that is recommended for pressure treated wood.
I have in the past written about painting wood cabinets as a low-cost alternative to replacing them. This often occurs because pressure treated wood is tightly bundled in stacks when it is shipped to the lumberyard. When wood is pressure-treated, it is saturated with a liquid solution of preservative diluted in water. Pressure-treated wood may not be the best choice for exterior trim, since most pressure-treated wood is southern yellow pine, a species that is not particularly good at holding paint.
I had a pressure treated wood deck built in October 2008 and have been searching for information on stains that can be used on the decking. Some had popped up quite a bit due to the shrinking and swelling of the wood in our variable Northern climate, and others just needed one good whack to seat them below the surface in preparation for our next step… sanding. By the way, the pressure washing will create a mess of flying debris about 10 feet out from your deck, so you might want to throw down some drop cloths, or plastic to protect your patio or whatever.
Ecolife, with its built in wood stabilizing system, has been specifically designed for above ground use, and as such has been proven to perform. AWPA treatments are a safe and proven means to preserve and protect outdoor wood from decay and termite attack. Solid-color stains and paints don’t usually work as well on the deck floor, because they can peel and are difficult to maintain.
Ecolife treated wood exhibits reduced cracking, warping and splitting in service, and uses no more chemicals than is absolutely necessary. If it is for a permanent application your best bet would be to use covers but if you are going to paint them.. Paint is paint and will need some refurbishing a few years down the road. If you haven’t considered staining your pressure treated products, it may be time to give it some thought.
Waiting too long to stain and protect your deck means the wood loses more of its ability let the stain adhere. Immersion (Professional users only): Completely submerge the wood in an open tank of preserver. A deck that does not get a lot of sunlight is more likely to have mildew staining and green moss. Sealing the top of the deck surface slows down the rate of evaporation so most of the evaporation will occur on the underside of the deck, causing the board to peak upwards… your desired result. Unless it’s a good grade 2Xkiln dried, you’ll have problems down the road if you use paint.
The green color you see on treated wood is caused by chemical reactions that take place between the preservative components and the wood. Pressure-treated wood may be used inside, and is commonly used for the sill plates of homes and FRTW; fire-retardant treatments like D-Blaze offer additional protection from fire and smoke development. I’ve heard several people say they typically wait about a month to stain a pressure-treated wood deck. I use black asphalt paint and it works fine but the key is to be sure they are good and dry before you try to paint or it will bubble. For cut ends of treated lumber, we recommend you use a brush-on wood preservative.
This a shot of the deck with the stain stripper on it. Great time to take a breather as it does it’s thing. Sealant also prevents the wood from drying to fast which will cause excessive warping. Without these special designations, your primer and paint job may not last long due to the wood’s resistance to liquids. But with the new deck, the new wood needs a little time to allow the chemicals or the moisture in the wood to evaporate a little bit, so that it will receive the stain or sealer in the best way possible. Penofin’s pressure-treated wood stain formula contains sustainably harvested Brazilian Rosewood Oil to give the wood a natural tone and texture.
Be sure to follow the paint or stain manufacturer’s recommendations and remember that horizontal surfaces will get much more punishment than vertical surfaces. Pressure-treated wood may contain arsenic, so EXTREME caution should be used when sanding it. Arsenic is known to cause cancer in adults and children. I just had new railings and spindles added to a porch and the wood is pressure treated.
Semi-transparent products let some of the wood grain show through, making them a good choice for cedar, redwood, and other costly woods that you want to show off. If paint is to be used, liberally brush the surface plus all ends and joints with a paintable water-repellent/sealer preservative and allow the surface to dry for at least two warm, sunny days before painting. EPA began investigating the risks associated with the use of pressure treated wood in the year 2000. However, one must distinguish between the toxicity of the chemical and the toxicity of the wood product in everyday use.
Pressure treated on the other hand is injected with preservatives and chemicals at high pressure driving the moisture in. You can paint it and it will probably look fine, I can also say with certainty from years of seeing it first hand that it will shorten the lifespan of the PT. Some formulations can be used immediately; others perform best when the wood is allowed to dry for a while.
