Initial Maintenance
1. Start by cleaning your deck with a cleaner/brightener that contains a mildewcide. Because your deck is new, this step is truly preventative.
2. Next, apply a water repellent for surface protection. Clear water repellant can be applied immediately to new pressure-treated wood. Your choice of sealer should include not only a water repellant but also a UV stabilizer to slow the discoloration process. Semi transparent stains with water repellant should be applied to new pressure-treated wood as soon as the wood is surface dry. The dryness can be determined by sprinkling a few drops of water on the surface. If the water is rapidly absorbed by the wood, apply a semi-transparent stain with water repellant immediately. If the water is not readily absorbed by the wood, wait a few days and then test again before applying the stain. We do not recommend the use of a conventional multi-coat paint system or varnish. The performance is nearly always disappointing, and repainting often has to be preceded by scraping and sanding.
First Year Maintenance
1. Reapply cleaner/brightener as described in the initial maintenance, as well as another application of your water repellant. The water repellant will keep your outdoor project looking fresh.
2. Complete your first year maintenance after 12 months. (Remember, even consistent maintenance will not prevent the natural defects of wood from surfacing - but your efforts can minimize them.)
Future Preventative Maintenance
1. Depending on the location of your outdoor project, with regard to direct sun exposure, foliage coverage, etc., it may be sufficient to clean/brighten and recoat every two years.
2. If you decide to wait two or more years to perform your next cleaning/brightening, you may want to use a power washer. Be sure that the cleaner/brightener you use contains a mildewcide.
3. After every cleaning, reapply your water repellant. |
