Vapor Retarder Adhesive CA

Polyether adhesive

6 months in the original sealed container.

Store in a tightly-closed container at temperatures between 41°F and 104°F (5°C and 40°C) in a ventilated place, away from heat and direct sunlight.

11.2 lb/gal (1.3 kg/L)

35,000 cP at 77°F (25°C)

32 g/L

Curing time at 77°F (25°C) and 50% RH*: 7 days depending on quantity applied.

*Curing time will be longer at lower temperatures.

The coverage rate is approximately 50 ft²/gal (0.8 L/m²) and may vary depending on the application technique and porosity of the surface.

All surfaces must be clean, sound, dry, and free of loose materials or contaminants such as water, frost, ice, oil and grease that would interfere with proper adhesion and compromise the performance of the product.

In accordance with the ICRI Technical Guideline No. 310.2R-2013, newly poured concrete surfaces must be finished by forming, wood float, steel or power trowel, or broom finished to meet the equivalency of a CSP type surface between a rating of 2 – 5.

Apply Vapor Retarder Adhesive CA with a 3/16" (4.8 mm) notched squeegee. Apply Vapor Retarder Adhesive CA ahead of the sheet application. Do not allow Vapor Retarder Adhesive CA to skin-over before the sheet is applied into adhesive. The sheet will not adhere where Vapor Retarder Adhesive CA has skinned over. Use a follow tool, weighted roller or broom the leading edge of the sheet to the substrate, working forward and outward as necessary to remove wrinkles. Avoid walking over the sheet and prevent adhesive displacement or damage during application.

Apply sufficient adhesive coverage to ensure 1/8" to 1/4" (3.2 mm to 6.4 mm) of adhesive bleed out at all laps. At end-laps, cut 45-degree dog-ear away from the selvage edge for all T-joints. For low-slope areas where the slope falls below 1/4" per ft (1.2°), and where otherwise specified, leave all side and end-laps "dry" and hot-air weld or torch all laps watertight.
