Facts about duradek continued

SUBSURFACE

The better the surface, the better-finished floor we can give you. Sanded plywood or cement board will give the best-finished surface possible. As a rule, ¼" x 3/8" plywood will warp due to absorption of moisture from the atmosphere. We recommend 'over laying' with minimum ½" and preferably 5/8" plywood or 5/16" cement board for the flattest possible subsurface.

SLOPE

For the best product performance and customer enjoyment of their deck surface, the structure should be sloped (ideally 2%) to eliminate ponding water. Should the puddling occur, the area will require more regular cleaning due to the build up of dirt and pollutants. Ponding water will not affect the waterproofing of the vinyl but may eventually cause premature discoloration.

PENETRATIONS

All penetrations (posts, pillars) must be sealed to prevent water entering under the vinyl. All wood posts or pillars will crack and give access for water to get into the subsurface and under the vinyl. Regular inspection and caulking is required. To completely waterproof a post, either fasten it to the fascia of the building or completely cover it with waterproof membrane and clad. When fastening metal rails or posts to the deck surface, all pilot holes should be filled with a sealant before screw is inserted.

INDOOR USE

When using the vinyl indoors where the temperature change is slight, the vinyl can be butt seamed with a chemical sealer (like a kitchen floor seam). No perimeter fastening is required to control shrinkage.

STAINS

Vinyl will resist most staining materials. Some do cause problems though. Exterior oil base stains, some oil stains, any tar or bitumen based product, fresh cedar, and some new wolmanized lumber may permanently stain the vinyl. Biodegradable matter such as leaves when left on the vinyl for a prolonged period may also be very difficult to clean. If any of the above should occur - try to clean it off as soon as possible so the stain doesn't have a chance to set. Refer to the Care and Cleaning Instructions on the back of the warranty card or on the website.

WARNING

Do not attempt to clean stains, paint or any blemish using any bleach, acetone, turpentine, lacquer thinner, ketone, acid or multipurpose stain or print remover or you may cause removal of the print. The directions must be followed explicitly to avoid damaging the print. The cleaning solution must be dabbed, NOT rubbed, and then cleaned well with cleanser and water and then flushed with lots of clean water. Always test on an 'out of the way' place to ensure there will be no problems.
