DIRECTIONS

A. SURFACE PREPARATION

- Surface temperature must be 7-32°C (45-90°F) during application and for 24 hours after installation.
- All substrates must be structurally sound, clean and free of dirt, oil, grease, loose/peeling paint, laitance, efflorescence, concrete sealers or curing compounds.
- Make rough or uneven concrete smooth to a wood float or better finish with a DYNA Underlayment.
- Do not level with gypsum or asphalt based products.
- Maximum deviation in plane must not exceed 6 mm in 3 m (1/4” in 10 ft) with no more than 1.5 mm in 0.3 m (1/16” in 1 ft) variation between high spots.
- Dampen hot, dry surfaces and sweep off excess water—installation may be made on a damp surface.
- New concrete slabs shall be damp cured and a minimum of 14 days old before application.
- Maximum amount of moisture in the concrete substrate should not exceed 2.26 kg/92.9 m2 (5 lbs/1000 square feet) 24 hrs. per ASTM F-1869 or 75% relative humidity as measured with moisture probes.

1. Installer must verify that deflection under all live, dead and impact loads of interior plywood floors does not exceed industry standards of L/360 for ceramic tile and brick or L/480 for stone installations where L=span length.

2. Minimum construction for interior plywood floors:

SUBFLOOR:
15 mm (5/8”) thick exterior glue plywood, either plain with all sheet edges blocked or tongue and groove, over bridged joints spaced 400 mm (16”) o.c. maximum; fasten plywood 150 mm (6”) o.c. along sheet ends and 200 mm (8”) o.c. along intermediate supports with 8d ring-shank, coated or hot dip galvanized nails (or screws); allow 3 mm (1/8”) between sheet ends and 6 mm (1/4”) between sheets edges; all sheet ends must be supported by a framing member; glue sheets to joints with construction adhesive;

UNDERLAYMENT:
15 mm (5/8”) thick exterior glue plywood fastened 150 mm (6”) o.c. along sheet ends and 200 mm (8”) o.c. in the panel field (both directions) with 8d ring-shank, coated or hot dip galvanized nails (or screws); allow 3 mm (1/8”) to 6 mm (1/4”) between sheets and 6 mm (1/4”) between sheet edges and any abutting surfaces; offset underlayment joints from joints in subfloor and stagger joints between sheet ends; glue underlayment to subfloor with construction adhesive.

B. APPLICATION

Read the Safety Data Sheet (SDS) before use. 

A) PRE-TREATING CRACKS AND JOINTS
Apply a liberal coat of AQUABAN 200 approximately 200 mm (8”) wide over substrate cracks, cold joints, control joints and board joints using a paint brush or roller (heavy napped roller cover). Place 150 mm (6”) wide AQUABAN 200 fabric into the wet AQUABAN 200 liquid. Press down on AQUABAN 200 fabric with brush or roller until the AQUABAN 200 liquid “bleeds” through from below. Then apply another liberal coat of AQUABAN 200 liquid over the entire surface of the fabric.

B) PRE-TREATING COVERS, CORNERS & SEAMS
Apply a liberal coat of AQUABAN 200 liquid approximately 200 mm (8”) wide over substrate coves, corners, seams, joints and changes in plane using a paint brush or roller (heavy napped roller cover). Fold 15 cm (6”) wide AQUABAN 200 fabric in half and place it into the coat of wet AQUABAN 200 liquid. Flash AQUABAN 200 fabric 75 mm (3”) up walls and other vertical surfaces. Press down on AQUABAN 200 fabric with brush or roller until the AQUABAN 200 liquid “bleeds” through from below. Then apply another liberal coat of AQUABAN 200 liquid over the entire surface of the AQUABAN 200 fabric.

C) MAIN APPLICATION
Allow any pre-treated areas to dry to the touch. Apply a liberal coat of AQUABAN 200 liquid with brush or roller over substrate including pretreated areas. Lay AQUABAN 200 fabric into wet AQUABAN 200 liquid and smooth out any wrinkles. Press AQUABAN 200 fabric with brush or roller until AQUABAN 200 liquid “bleeds” through to surface. Lap seams approximately 50 mm (2”). Flash AQUABAN 200 up over pretreated coves and corners, so such areas have two layers of AQUABAN 200 fabric. Apply another liberal coat of AQUABAN 200 liquid over AQUABAN 200 fabric to saturate it. Let topcoat dry to the touch, approximately 1-3 hours at 21°C (70°F) and 50% RH. Make another liberal coat of AQUABAN 200 liquid to seal entire surface. When last coat has dried to the touch, inspect final surface for pinholes, voids, thin spots or other defects. Use additional AQUABAN 200 liquid to seal defects.
