PROSOCO 70440 Air and Water Barrier AirDam Instructions
PROSOCO R-Guard® AirDam® is a gun-grade waterproofing sealant combining the best of silicone and polyurethane properties. Installed as the interior air sealant, AirDam® creates a long lasting, weather-tight seal that prevents moist outside air from entering, and conditioned indoor air from escaping around window and door assemblies. This ensures wind driven rain and condensed water are diverted to the flashing membrane and water resistive barrier before it can enter the living space.
This single component, Silyl-Terminated-Polymer (STP) is easy to gun and tool in all weather conditions. AirDam® is immediately waterproof and can be applied in unfavorable weather conditions to dry or damp substrates, eliminating many weather-related construction delays and accelerating the “drying in” of new buildings.
AirDam® cures quickly to produce a durable, high performance, high movement elastomeric sealant. Appropriate for exterior or interior use, AirDam® is easily applied with standard caulking tools. AirDam® bonds tenaciously and can be used with all types of window and door frame material – vinyl, wood or metal, including painted metal. As a properly applied interior window sealant, AirDam® can substantially reduce a building’s heating and cooling costs.
ADVANTAGES
- Solvent free. Isocyanate free. Complies with all AIM VOC regulations.
- Silane functional polymer provides superior long term adhesion, crack bridging and weathering characteristics.
- Bonds to most common building materials without priming.
- Produces a durable, weather-tight seal.
- Suitable for exterior or interior use.
- Stops penetration of air and water under normal and extreme weather conditions.
- Single component formulation saves time and requires no mixing.
- Easy to gun and tool in all climates.
- Bonds and cures in wet weather and on damp substrates.
- Compatible with most sealants and waterproofing or air barrier components.
- No shrinkage. No staining. Non-yellowing.
- Breathable – allows damp surfaces to dry.
- Will not support mold growth.
- PROSOCO R-Guard® Joint & Seam Filler, FastFlash® and AirDam® are recommended for improved performance of all R-Guard air- and water-resistive barrier coatings.
- Illustrations depicting the use of PROSOCO R-Guard® products are available at prosoco.com by downloading the R-Guard Installation Guidelines.
Limitations
- Not for use bridging gaps more than 2 inches wide.
- Not for underwater applications.
- Not for applications in direct contact with strong acids or solvents.
- May have slight incompatibility with some asphaltic materials or butyl adhesives. Always test first.
REGULATORY COMPLIANCE

TYPICAL TECHNICAL DATA
Cured Properties
PREPARATION
AirDam® bonds tenaciously. Carefully protect people, vehicles, property,
plants, and all other surfaces not intended to receive AirDam®.
Immediately clean up incidental contact using mineral spirits or similar
solvent.
Surfaces must be structurally sound and free of any surface contaminants, chemical residues, surface coatings or films that may adversely affect adhesion.
Pressure-treated wood or fire-retardant wood and other contaminated surfaces should be cleaned with an Isopropyl Alcohol wipe and allowed to flash-off before application of R-Guard products.
Joint Preparation
For joints less than one-half (½) inch wide, sealant depth should be equal to
the width of the joint.
For joints ranging from one-half (½) to one (1) inch wide, sealant depth
should be approximately one-
half (½) the joint width.
In deep joints, control sealant depth by installing closed cell backer rod. The diameter of soft backer rod should be 25% greater than the joint width. Do not puncture backer rod.
Where joint depth does not permit use of a backer rod, install bond breaker tape to prevent three point bonding.
Surface and Air Temperatures
Substrate and temperature conditions should be 32°F (0°C) and rising and below
110°F (43°C) during application and drying. If air or surface temperatures
exceed 95°F (35°C), apply to shaded surfaces and before daytime air and
surface temperatures reach their peak.
Hot Weather Installations: when practical install AirDam® to shaded surfaces. When conditions are hot and dry, cool and dampen the surface with a fresh water mist. Allow standing water to dry before installation.
Though AirDam® may be applied to damp surfaces and tolerates rain immediately
after application, do not apply to surfaces with standing water or frost.
Contact PROSOCO if conditions are questionable.
As with any coating, application to substrates with high moisture content may
lead to blistering of thematerial.
Equipment
Apply using a professional caulking gun and standard caulking tools. Avoid
over tooling. To tool the product, use a DRY joint knife slightly wider than
the gap or joint opening. Do not use soapy water or solvent to help with the
tooling process or to slick the surface profile.
Storage & Handling
Store in a cool, dry place. Keep container tightly closed when not in use. Do
not open cartridges or sausages until preparation work has been completed. Do
not alter or mix with other chemicals. When stored at or below 80°F (27°C),
AirDam® has a shelf life of 12 months after the date of manufacture. This
shelf life assumes upright storage of factory-sealed containers. Do not
doublestack pallets. Keep out of the reach of children.
Dispose of in accordance with local, state and national regulations.
APPLICATION
Before use, read “Preparation” and the Safety Data Sheet.
ALWAYS TEST each surface for suitability and desired results before overall application. Use the following application instructions. Let the surface dry thoroughly before inspection and approval.
Dilution & Mixing
Apply as packaged. Do not dilute or alter, or use for applications other than
specified. AirDam® is ready to use. No mixing is required.
Coverage Rates
Coverage varies depending on the width and depth of joints. When overlapping
onto adjacent surfaces, rough surface irregularities will reduce coverage.
Use the table below as a guideline when estimating sealant requirements.
Application Instructions
- Using a professional grade caulking gun, install sealant in a continuous bead without gaps or air pockets.
- Tool sealant immediately to ensure complete wetting of joint bond surface and to produce a smooth, concave joint profile flush with the edges of adjacent surfaces. Where horizontal and vertical surfaces meet, tool sealant to create a slight cove which will not trap moisture or debris. DO NOT use water, soapy water or solvent to tool. Avoid over tooling.
Curing and Drying
AirDam® cures at the rate of 1/8 inch of depth per day. Allow for drying time
based on temperature and humidity. High humidity decreases curing and drying
time. Low temperatures and low relative humidity will extend curing and drying
time.
Cleanup
Clean tools and equipment immediately with mineral spirits or similar solvent.
