Description:
Aquaseal is a proprietary self adhesive 25 mil membrane sheet which requires minimal labor for installation. It combines high strength, low temperature adhesion and high temperature stability which creates a superior barrier to limit air and moisture transmission. Unlike air/vapor barriers with no adhesive backing which require stapling, Aquaseal is self adhering. If stapled however, Aquaseal will seal itself around all the staple holes. The combination of 4 mils cross laminated polyethylene and 21 mils rubberized asphalt produces a product which is tough and resilient to physical damage. Aquaseal is cold applied and requires no maintenance after installation

Uses:
Aquaseal is used to prevent air and vapor transmission through masonry curtain walls, construction joints and fittings around doors and windows. Can be applied to wood, concrete, metal and concrete block.

Application:
Surface Preparation:
All substrate surfaces must be dry, clean and smooth. Structural concrete needs to be cured a minimum of seven (7) days. Wood composition panels, especially Oriented Strand Board (OSB) may require priming. When surface is cannot be made smooth, Aquaseal can be mechanically fastened with nails, screws or staples.
Primer:
Prime dusty, weathered or dirty surface with Aquaflash Primer. Allow primer to dry prior to installing Aquaseal membrane.
Application:
Cut Aquaseal into manageable lengths and remove the release liner. Apply membrane from the lowest point upward and in a shingle fashion overlap horizontal edges. Use a hand held roller to ensure uniform contact with substrate. Reinforcing strips on all outside and inside comers as well as mechanical fastenings to windows frames and doors is recommended. Seal all terminations, protrusions and detailing with Aquaflash Mastic

Technical Data Table

Model Guide Specification:
The product for air/vapor barrier for (windows, doors, etc.) shall be Aquaseal, a composite 25 mil sheet membrane consisting of 4 mils cross laminated polyethylene with 21 mils of rubberized asphalt as manufactured by Fiberweb div. of Clark/Hammerbeam Corporation followed by installation instructions.

Safety, Storage and handling:
Aquaseal is to be installed in ambient temperatures of 50 degrees F and above. When Aquaseal is to be installed below 50 degrees F, store at room temperature and prime the substrate with Aquaflash Primer to insure good initial bond.

Pallets of membrane should not be double stacked on jobsite.

Avoid prolonged and repeated contact with skin. Consult Material Safety Data Sheet
