Applications & Uses

Cleaning Information

Use fresh water for cleaning brushes and equipment before product dries.
Dry product may be removed with hot soapy water (with ammonia added) or strong solvents such as chlorinated solvent (non-flammable) or xylol (flammable).

Preparation and Application Information

Preparation

Stir well, Do not thin.
Apply only to clean, dry, oil-free surfaces.
Keep container closed when not in use.

Application

To prevent water vapor and moisture infiltration, proper and complete flashing is required.
Follow flashing specifications.

Indoor and light duty outdoor

Apply tack coat of Foster® VAPOR-SAFE® Coating AF at 2 – 4 gallons per 100 square feet (0.8 – 1.6 l/m2 ).
Embed Foster® MAST-A-FAB® White Membrane into the wet tack coat. Smooth membrane to avoid wrinkles and overlap all seams at least two inches (5 cm). Apply finish coat of VAPOR-SAFE® Coating AF, within 1/2 hour of the tack coat application, at 2 gallons per 100 square feet (0.8 l/m2 ).
This application shall provide a minimum dry film thickness of 37 – 56 mils (0.9 – 1.4 mm).
Do not use with canvas or other closed weave cloths.

Brush

Use a good brush (suitable for water-based paints), making strokes as long as possible over the surface.
Apply with full brush and spread out evenly.
Do not overwork.

Spray

VAPOR-SAFE® Coating AF may be airless spray applied.
For spray equipment information, please consult Airless Spray Recommendations or contact your airless spray equipment supplier.
Average viscosity range: 60,000 – 90,000 cps.
Corrosion resistant pumps and fittings are suggested.

Product Highlights

FOSTER® VAPOR-SAFE® COATING AF is a water-based, fire- resistive, flexible, high solids, vapor retarder finish for most types of thermal insulation, including polystyrene foam.
It may be used over dry concrete and finishing cement.
It is designed for use in high humidity areas to resist mold, fungus and mildew growth on its surface and protect the insulation system from their discoloring and deteriorating effects.
VAPOR-SAFE® 30-80AF™ has the water resistance and low water vapor permeance normally only found in solvent-based products.
It can be used in high humidity environments and greatly retards water vapor permeation.
It is non-flammable in the wet state.
VAPOR-SAFE® 30-80AF™ is formulated for both indoor and light duty, commercial, outdoor use.
It is UV resistant. It has a mild, latex “paint- type” odor, and is designed for use over insulation on pipes, vessels, ducts and equipment operating below ambient temperatures.
VAPOR-SAFE® 30-80AF™ is ideal for vapor sealing ASJ, FRK and FSK jackets and board facings at joints, laps and over staple and weld pin punctures.
It is an excellent duct board closure sealant. Do not exceed 1/8” (3.2 mm) wet film thickness.
VAPOR-SAFE® 30-80AF™ meets the requirements of Military Specification MIL-PRF-19565C, Type II using method AS™ E96, Procedure A permeance.
VAPOR-SAFE® COATING 30-80AF™ meets the requirements of:
- MAS Certified Green®
- California Dept. of Public Health Standard Method v1.2
- VOC Emissions and Content requirements to contribute to LEED v4 EQ Credit: Low Emitting Materials – Paints and Coatings
- Collaborative for High Performance Schools EQ 7.1

Storage & Handling

Handling Conditions

Store and apply between 40°F (4°C) and 100°F (38°C), protect from freezing until dry.
To resist rain wash-off, allow at least 8-12 hours drying time above 50°F (10°C), with a relative humidity of 50%.
Higher humidity and/or lower temperature may retard drying.
Always select coating in the white color for use over polystyrene on outdoor installations.
After long term exposure, 30-80AF™ may weather to an off-white color.
Always test foil and paper facings for acceptable adhesion before using.
Outdoor horizontal surfaces must always drain completely.
A pitch of at least 1/2” per foot (4 cm/m) is required.
This product does not protect users or others against bacteria, viruses, germs or other disease organisms.
It does not take the place of normal cleaning and disinfecting procedures.
