Features & Benefits
- Ready-to-Use Product Features
- Outstanding Features
- Can be used over BUR, capsheet, modified, steel, aluminum, tin, zinc, concrete, transite, and single-ply
- Will cure underwater regardless of applied coating thickness
- Produces a fully adhered, seamless, high-density, waterproofing membrane
- Remains flexible, tough, and weatherproof at low temperatures and will not flow at high temperatures
- Apply straight out of the container by brush or roller
- Uses DuPont Kevlar® technology to achieve super strength and durability
- Will not re-emulsify or wash away with water
- May be used on vertical, pitched, and horizontal
Applications & Uses
- Application
Although only minimal preparation is required, all loose material, stones, and grease should be removed, together with as much dust, rust, and standing water as is reasonably possible. Bird excrement, algae, and slime mold should be scrubbed off of the surface for best adhesion results. All holes, gaps, and joints should be bridged with fabric sandwiched between sufficient AcryPair™ to provide thorough wetting of the roof surface and thorough saturation of the fabric. This is best accomplished by “stippling in” with a brush. AcryPair™ may be applied in 2 coats of 20 wet mils thickness each over single-ply, capsheet, modified, metal, transite, or concrete after the above preparation is complete. The 1st coat may be applied directly over any fresh, wet repairs as curing will proceed regardless of thickness although slower. The 2nd coat may be applied as soon as the 1st coat is sufficiently dry to walk on (normally 2-3 days at 65°F). Care should be taken not to disturb any patches or pretreatments as they may still be wet.
AcryPair™ may be applied over asphalt or coal tar BUR after the preparation described above has been completed. The 1st coat should be applied at 66 square feet per gallon; fabric laid into it and thoroughly “stippled in” by brush with a 2nd coat at 66 square feet per gallon to remove all tents and voids. The fabric should be overlapped by at least 2 inches and thoroughly saturated with AcryPair™ so that no dry spots remain.
- Limitations
Not recommended in areas of high chemical attack (around stacks, etc.). AcryPair™ does contain solvent so H.V.A.C. equipment should be prevented from drawing air from the rooftop during application.
- Coverage
Approx 30 to 40 square feet per gallon, depending upon substrate.
- Equipment
Application Equipment: Brush, roller or spray
Cleaning Equipment: Mineral Spirit
