Foster® Vapor-Safe® Coating 30-80
1 of 34 products in this brandFoster® Vapor-Safe® Coating 30-80 is a water-based, fire-resistant, flexible, high-solids vapor retarder finish suitable for various types of thermal insulation, including polystyrene foam. It can be applied to dry concrete and finished cement surfaces. This coating is formulated for both indoor and light-duty commercial outdoor use, featuring UV resistance. It has a mild, latex "paint-type" odor and is intended for use over insulation on pipes, vessels, ducts, and equipment operating at cryogenic to ambient temperatures.

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 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, 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 cloth.
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 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 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.
- VAPOR-SAFE® COATING has the low water vapor permeance normally found in only 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® COATING 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 at cryogenic up to ambient temperatures.
- VAPOR-SAFE® COATING 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® COATING meets the requirements of Military Specification MIL-PRF-19565C, Type II using method ASTME96, Procedure A permeance and is QPD-19565 Listed. VAPOR-SAFE® COATING contains no asbestos, lead, mercury or mercury compounds.
- VAPOR-SAFE® COATING 30-80 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
