The MULTI-DECK SYSTEM FOR WOOD SUBSTRATES is a multi-layer, waterproofing, and decorative protective coating designed for above grade wood decks. The system is designed to withstand heavy foot traffic on decks, ramps, walkways, etc.
Over 2.5 galvanized metal lathe in a staggered pattern over the entire plywood/OSB surface overlapping the metal flashing to the edge of the deck surface. Mix MULTI-BASE per instructions on the bag and pour over the metal lathe. Trowel onto the deck covering the metal lathe and allow to dry completely.
MULASTICOAT® is then applied over entire surface in two (2) coats with roller, using firm pressure. Embed POLYESTER STITCH BOND FABRIC in the first coat while wet over all flashings. First coat is considered “dry” when dry to the touch which is usually 1-2 hours depending on ambient temperature. The second coat is applied crisscross to the first coat. Broadcast silica sand over wet material to promote mechanical bonding to the following protective decorative finish. After product has dried for a minimum of 24 hours, or longer for cold weather, brush off lose sand before applying a decorative wearing surface.
Apply Krete Kote or Top Coat in 2 steps: a base coat, and a texture coat. Apply a smooth thin layer with a trowel, sprayer or magic trowel and allow to dry. Then apply a texture on top top desired aesthetic look.
Apply the diluted COLORSEAL with nap roller for the 1st coat with very firm pressure. (1/2” nap roller for smooth and 3/4” nap roller for rough surfaces). Allow a minimum of one (1) hour to dry. For the 2nd coat, apply at full strength. Airless sprayers may be used for the 2nd and final coat. Allow final coat a minimum of 24 hours before placing area into use. Will fully cure in 14 days, during which care should be exercised against excessive abuse.
A: No, it is best practice to remove an old, failing system before applying a new waterproofing system such as The Multi-Deck System – Wood Substrates.
A: No, the lathe and the Multi-Base restrict the movement of the deck and provide more structure to the surface. It is necessary to fight thermal expansion and contraction and gives an added fire resistance to the system.
A: Comparing different systems on the market, Multi-Deck is a very cost effective option for waterproofing your deck. Call us today to locate a Certified Applicator near you.
A: We recommend embedding a material called Polyester Stitch Bond Fabric into the first coat of BG2000 to act as a reinforcement material for high movement areas. It is an inexpensive way to ensure security and rigidity in areas that may be subject to extreme movement over time.
