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.

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.

Q: Can Wood Multi-Deck be applied over my existing waterproofing?
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.
Q: Can I skip the lath and Multi-Base steps and apply the waterproofing directly to the wood surface?
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.
Q: Is Multi-Deck expensive?
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.
Q: How do you bridge expansion joints and wall/floor 90º joints?
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.
