A-9,000 System Specification

Wood Structures

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.

Plywood Seam

All plywood seams must be nailed with ring-shank nails or screwed and must be blocked from underneath.

Metal Flashing

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.

Metal Lath

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.

Crickets

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.

Waterproofing Basecoat

  1. Using a good strong drill mix 4 1/2 to 5 quarts of water with (1) 50 pound bag of A-900 Waterproofing Basecoat.
  2. Adding the cement into the water, will insure a thorough mix. Screed trowel wet mixture directly into, 2.5 galvanized, diamond lath at a rate of 35 to 40 square feet per mix.
  3. Metal lath must be completely covered. Allow to dry. Scrape off any high points or trowel ridges.

Waterproofing Primer and Flex Mesh

  1. Apply A-1600 Flex Mesh over entire surface with 1” to 2” overlap at all seams.
  2. Saturate A-1600 Flex Mesh with A-8100 Waterproofing Primer and allow to dry.

Concrete Resurfacer

  2. Apply to deck with a hopper gun at a rate of 125 to 150 square feet per bag. In golf shoes or spikes, knock down A-800 Texture Finish with a trowel, keeping trowel clean and damp with wet rag or sponge.
  3. Let dry for 24 hours. Apply A-1100 Color Seal or A-1150 Heat Reflective Color Seal over surface (2 coats). Apply the first coat at a rate of 250 square feet per gallon. Allow to dry and then apply a second coat at a rate of 250 gallons per square foot.

 

Flashing Procedure for Americrete’s Waterproofing System

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.
