Tips for Choosing the Best Deck Stains and Sealers for Pressure Treated Wood

How to seal pressure treated wood deck
To seal the deck, start with the right preparation of the surface for coating. Start with checking up the moisture content in the wood surface, as bare wood has to be dry to prevent coating failure due to adhesion loss. If possible, use a moisture meter: usually, outdoor surfaces have to contain no more than 15-20% moisture, and interior surfaces can have only 12-15% moisture before sealing.
To prepare bare wood for staining and transparent finishing, the best option is to put a professional primer on the knots. One of the best products for the effective preparation of a shellac-based primer. They do have an odor, but it will disappear shortly after the application. Using a primer, you save your wood from the possible knots and bleeding through the finish layer.
No need to use primer when staining bare wood – in case there are any knots, the stain will effectively saturate all of them. The nest treatment includes removing all oozing sap, and it is essential for those who work with pine, fir, or similar wood types. Just after removing the sap, the surface is ready to apply for applying an appropriate primer or sealer in the areas affected by sap.
The last stage of wood treatment is filling all holes and cracks in case they are present on the surface and move on to the sanding process. Cracks can be easily removed with professional wood filler. To lower the crack shrinking, use wood filler of the highest grade. Sand in the grain direction because doing it across the grain will result in multiple scratches that can unevenly absorb stain and polyurethane.
When starting to seal the deck, use a clean brush, moving it evenly and quickly in the wood grain direction. Check all surfaces for being correctly covered with special attention to the end grains. The unsealed end grain will absorb stain and finishes for wood decks deeper than the rest.
The sealer has to completely dry within the period mentioned on the product packing – it usually takes from 1 to 2 hours. Then gently sand the surface with sandpaper. Keep in mind that very porous types of wood surfaces might require several coats of sealer.back to menu ↑
