Accent and enhance your wood’s natural patterns while providing increased protection from the elements with BEHR’s Semi-Transparent Waterproofing Wood Stain. I recently finished my 10×16″ deck, pressure treated pine, with Cabot Uustralian Timber Oil. I have yet to find an acrylic or latex primer that works as well for exterior as oil. So, as your deck boards expand and contract with variations in temperatures and weather conditions, paint begins to chip and you end up with peeling paint, rotting wood and other potential problems. These are resistant to the chemicals in PT wood and some even have lifetime guarantees.
Often times this problem will be most evident in the spring time when the deck begins to dry out after all of the winter moisture. The best TWP stain for pressure treated pine where the 100 Series is not available is TWP 1500 Series. We suspect that the new ACQ treated pine, if properly resealed every 5 years or so, is a lifetime product. After 6 months use a good quality oil or alkyd based primer and a solid color stain from a quality mfr ?(Cabot, Olympic etc from a real paint store not a box store).
While pressure-treated is intended to protect primarily from insects, fungus, bacterial rot, exterior weather exposure and UV in sunlight will definitely result in checking and splintering of the surface. While pressure-treated wood offers many benefits, structures built from it often leave something to be desired in appearance. To extend the performance of the deck materials and components, regular inspection and maintenance should be performed. Applying stain to a deck is pretty straight forward, but there are some tips and tricks that will assist you during the process.
However, one must distinguish between the toxicity of the chemical and the toxicity of the wood product in everyday use. Sealer for pressure treated wood is a penetrating oil finish that reduces or even eliminates exposure to the chemicals used in the treatment process of the wood. We have a wide variety of pressure treated wood which is used in our fence panels, check some of them out and see if they are fit for your purpose.
Surprisingly, mildew grows quite well on unprotected, pressure treated lumber and it must be removed before painting. Consumer Reports buys and tests various stains by painting wood panels and leaving them exposed to the elements. Keep in mind when staining your deck that it is probably going to need to be reapplied at least once a year, unless you choose an alternative type of deck stain or paint. Use a piece of scrap wood from your project or find an inconspicuous spot on the finished project to test the stain.
And you need to make sure it will remain at least the 40 or 50 degrees for 24 hours after you stain the deck so it will dry properly. The bleach is usually diluted with water (1 part bleach, 3 parts water) before it is applied to the deck. Pressure-treated wood has a high moisture content, which prevents some stains and sealers from penetrating the wood. I bought my house when it just had a new PT wood front porch put on it. The guy I knew at Sherwin Williams said to wait a YEAR and I did.
Additionally, some of the waterborne stains are synthetic, such as DEFY Extreme Wood Stain Synthetic resin wood stains are far less susceptible to mold growth, mildew, and algae. Williams found that the key factor in getting the most longevity out of any surface finish – whether stain or paint – is to seal the wood before the sun ever hits the surface.
Staining pressure treated wood railings on you porch is a great way to make an unfinished space feel finished. Treated Southern Pine lumber will accept a finish similar to untreated material. Wash away the dirt with a hose or a very low setting (below 500 psi) on a pressure washer. You can spray the deck cleaner onto the wood using a garden sprayer or other spraying device. We usually just coat them straight up with exterior latex (two coats using a roller).
