A-9,000 Specification
Wood surfaces must be free of oils, contaminants, trash, sawdust, etc. and must be structurally sound and secured by screws or ring shank nails and blocked at all plywood seams before application. This system can be applied directly over existing wood surfaces consisting of 5/8” tongue and groove plywood or thicker. This system is not approved over 1/4” plywood or OSB board. Apply over recommended surfaces only. Plywood must have a 1/4” per foot slope away from the building.
All plywood seams must be nailed with ring-shank nails or screwed and must be blocked from underneath.
Metal Flashing should be 26 gauge galvanized bonderized metal. All wall to deck flashing shall be 4” x 4” or better. Flashing shall be overlapped by 3” to 4” and caulked with 2 beads top and bottom at all overlapped areas. Vertical and horizontal caulking shall be RainbusterTM 500 or 900 or equal. Fascia flashing is to be 2” x 4” with drip edge and no gravel stop. All flashing is to be nailed every 4” and vertical areas to be nailed at the top of all stud areas.
Plywood Seam
All plywood seams must be nailed with ring-shank nails or screws and must be blocked.Americrete does not guarantee that the cracks will not appear at a later date.
A 2.5 hot dipped galvanized expanded metal lath must be applied over plywood and metal surfaces with all diamond metal lath seams overlapping 1″- 2″. Lath to be fastened by stapling with galvanized 1”crown by 5/8” leg staples, minimum of 18 staples per square foot. All overlapped lath shall have staples every 1” on the seams. Hammer down seams to be even with the rest of the field.
When installing lath on an enclosed parapet wall deck, crickets may be required to get water off the deck and into scuppers or drains. You can achieve this by cutting lath pieces at 45-degree angles and nailing them between drains or scuppers. Use 3 pieces of lath, each one cut smaller than the prior, and lay them on top of another and secure with staples or nails. This will achieve a gradual build-up when A-900 Waterproofing Basecoat is applied into lath.
1. Apply 4” x 4” or 6” x 4” flashing at walls and over threshold areas. Overlap flashing ends by 4” and apply 2 beads of caulking RainbusterTM 500 or 900, or the equivalent, at each seam of the flashing, top and bottom. Put 2 nails at all vertical and horizontal seams, top and bottom. Nail the flashing that is laying on the deck surface, every 4” to 6”. Nail the flashing that goes up the wall at every stud. End the flashing at a stud.
2. The wall-to-deck flashing must be installed behind the weep screed and building paper. The weep screed should be kept off the deck at least 1 . inches.
3. Then apply 2” x 4” fascia flashing at the end of the deck. Remember to caulk and nail all of the areas where metal is overlapping.
4. If stucco is to be applied at the edge of the deck, be sure to leave the flashing .” beyond the deck to accept the stucco. The stucco should be under the flashing.
5. If a parapet wall is designed around the deck, you should have scuppers, drains or both, and an overflow scupper so the water will drain properly.
6. Where drains are required, Americrete approves Thunderbird Deck Drains. Use galvanized/bonderized deck drains and scuppers. If scuppers or drains are required, be sure the distance between each is no more than 6 feet. Install crickets between scupper with lath and A-900 Waterproofing Basecoat. Build up at 45-degree angle to divert water toward drains.
7. All decks must have at least 5/8” Tongue and groove Plywood blocked at all seams, with joists 16” on center and they must be 2” x 8” or greater with 1/4” fall per foot. All decks are to be screwed or nailed with ring-shank nails, glued and blocked.
Always use Americrete flashing procedures.
1. Apply 2.5 hot-dipped galvanized, metal lath over the deck surface and fasten with 5/8” x 1” crown,non-corrosive staples. Staple patterns must be a minimum of 18 staples per square foot. All lath seams must overlap 1” to 2” and metal lath shall be no more than .” away from the walls or edge of the deck covering all flashing. Hammer staples down at lath seams before applying A-900 Waterproofing Basecoat.
2. After lath has been applied, mix 4 . to 5 quarts of water to (1) 50 pound bag of A-900 Waterproofing Basecoat and trowel into the lath at a rate of 30 to 35 square feet per bag (lath should be completely covered). Allow to dry completely.
3. Apply A-1600 Flex Mesh over the entire surface.
4. and saturate the nylon mesh with A-8100 Waterproofing Primer by using a roller. Allow it to dry.
5. Mix 5 1/2 to 6 quarts of water per 50 pound bag of A-600 Concrete Resurfacer and apply using a squeegee at a rate of 150 square feet per bag and cover the A-1600 Flex Mesh completely.
6. Next, for a knock down finish, mix 4 1/2 to 5 quarts of water to each 50 pound bag of A-800 Texture Finish.
7. Put the material into a Hopper Gun with low pressure.
8. Apply by spraying material onto the deck. Let it set-up. Do not allow it to dry, walk onto the surface with golf shoes or spikes and proceed by knocking down the Texture Finish with a trowel. Allow it to dry for 24 hours.
9. Scrape the deck and blow or sweep the debris off the deck.
10. Apply 2 coats of A-1100 or A-1150 Color Seal with a roller at a rate of 250 square feet per gallon. Allow it to dry between coats.
Galvanized Thunderbird drains (2” or 3”) should be placed no more than 6 feet apart from each other. They must be nailed and caulking must be placed under and around the drains. If drains are needed, an overflow drain should also be installed. See plans or specifications for your project.
Galvanized scuppers 2” x 3” or better, no more than 6 feet apart from each other.
Use joist size recommended in IBC and IRC, 16” on center with .” fall per foot better. (See Tables R502.3.1 in the International Residential Code).
5/8” or better, exterior grade, tongue and groove plywood, blocked and glued fall per foot. Nails should be screws or ring-shank nails. No OSB board or particleboard. This system is not approved over plywood that is less than 5/8” in thickness.
This can be done by mixing one 50-pound bag of A- 900 Waterproofing Basecoat with 1 gallon of A-8100 Waterproofing Primer. Prime the surface before application with A-8100 Waterproofing Primer. Do not allow the primer to dry before applying A-900 Waterproofing Basecoat.
