- Finish for all cold insulation systems.
- It is also recommended for hot, exterior, sprayed polyurethane applications.
- In both cases, Childers® Encacel® V CP-45 Vapor Retarder Coating is used as the finish coat after flashing and sealing all metal protrusions throughout the surface of the insulation.
- Childers® Encacel® V CP-45 Vapor Retarder Coating can be used as a decorative finish over closed-cell, flexible, cellular plastics.
- Care must be taken that the adhesive-bonded joint is not adversely affected by the solvent in the vapor retarder.
- It is not to be used in direct contact with polystyrene foam insulation.
- Childers® Encacel® V CP-45 Vapor Retarder Coating can be applied by spray or brush (for applying by glove or trowel, ENCACEL® X CP-40 vapor retarder coating is recommended).
- With its excellent bridging properties, Childers® Encacel® V CP-45 Vapor Retarder Coating will provide a smooth finish, even over relatively rough substrates.
- On large exterior surfaces, such as sprayed polyurethane foam, airless spray provides the most economical and efficient method of application.
- Over sprayed polyurethane foam, a two-coat, two-color system is suggested to eliminate voids and holidays.
- It is suggested that Childers® Encacel® V CP-45 Vapor Retarder Coating be stored at a minimum of 50°F (10°C) just prior to application to achieve optimum results.
- Outdoor horizontal surfaces must always drain completely.
- A pitch of at least 1/2” per foot (4 cm/m) is recommended. Childers® Encacel® V CP-45 Vapor Retarder Coating will not check or crack in exterior applications.
- The cured film of Childers® Encacel® V CP-45 Vapor Retarder Coating is fire-resistive and tough, yet flexible.
- It is resistive to many acids and alkalis.
- The excellent spray characteristics of the product minimizes the possibility of “pin-holing”, resulting in a uniform, monolithic film.
- Cetified
- This product has been tested according to ASTM E84 (Surface Burning Characteristics of Building Materials).

Notes to Specifying Engineer
- Flashing Prior to the application of the vapor retarder coating system, a complete flashing shall be provided at all metal-to-insulation joints and/or protrusions through the insulation.
- Uniformity of surface shall be made by cutting or shaving the insulation on these protrusions as necessary.
- By trowel, apply a 1/16" (0.15 cm) wet coat of CHIL-BYL® CP-76 Joint Sealant a minimum of 3" (7.62 cm) over insulation and metal protrusions.
- Embed CHIL-GLAS® #10 Glass Fiber Reinforcing Mesh into wet CHIL-BYL® CP-76 a minimum of 3" (7.62 cm) over insulation and metal protrusions.
- By trowel, apply a 1/8" (0.30 cm) coat of CHIL-BYL® CP-76 over the entire glass fiber reinforcing mesh.
- Allow a minimum of 24 hours drying time for the applied flashing system.
- Apply Childers® Encacel® V CP-45 Vapor Retarder Coating a minimum of 3" (7.62 cm) out over the insulation.
- When using a solvent vapor retarder such as Childers® Encacel® V CP-45 Vapor Retarder Coating, the joint sealant to be used shall be CHIL-BYL® CP-76. CHIL- JOINT® CP-70 Joint Sealant should not be used for this application.
- In applications where insulation has been fabricated with asphalt adhesive or where asphalt has been used as a joint sealant, there may be discoloration of the Childers® Encacel® V CP-45 Vapor Retarder Coating. This discoloration will not affect the overall physical properties of the dry film.
- Recommended Spraying Equipment Normal surface irregularities of sprayed polyurethane foam require correct atomization of sprayed coatings in order to achieve uniformity of dry film thickness. Childers® Encacel® V CP-45 Vapor Retarder Coating can be sprayed with a variety of airless pump models.
- Preparation and Application Information
Normal Service
- Apply a tack coat of Childers® Encacel® V CP-45 Vapor Retarder Coating at a thickness of 1/32 inch (0.8 mm).
- This is equivalent to 2 gal./100 sq. ft. (0.8 l/m2 ).
- Embed Foster MAST-A- FAB® or CHIL-GLAS® #10 White Membrane into wet tack coat.
- Smooth membrane to avoid wrinkles and overlap all seams at least 2 inches (5 cm).
- Apply a finish coat of Encacel Coating at a minimum thickness of 1/16 inch (1.6 mm).
- This is equivalent to 4 gal./100 sq. ft. (1.6 l/m2 ).
- This finish coat shall be applied no later than 2 hours after the tack coat and shall completely cover membrane.
- This application shall provide a minimum dry film thickness of 29 mils (0.7 mm).
Severe and Cryogenic Service
- After the first two coats have set, 24 hours minimum or until dry, apply an additional coat of Encacel Coating at a thickness of 3/64 inch (1.2 mm).
- This is equivalent to 3 gal./100 sq. ft. (1.2 l/m2 ).
- This additional application shall provide a minimum dry film thickness of 42 mils (1.05 mm).
- On rough or porous insulation surfaces additional product will be required to achieve the full surface dry film thickness.
- The application rate may need to be increased by up to 20% or more to achieve minimum film thicknesses.
- User shall determine required material based on specific substrates and application methods.
On Sprayed Polyurethane Foam
- Many sprayed polyurethane foam systems are different; end user should always perform an adhesion test to ensure that the adhesion of Childers® Encacel® V CP-45 Vapor Retarder Coating to the foam insulation to be used is sufficient.
- If adhesion is not sufficient the sprayed polyurethane foam may need to be primed prior to the application of coating to improve adhesion.
Brush
- Use a good brush, making strokes as long as possible over the surface.
- Multiple coats may be needed to achieve the minimum dry film thickness.
- Do not overwork.
Clean Up
- Use xylol (flammable) or chlorinated solvent (non-flammable) for cleaning equipment.
- Dried Encacel Coating is extremely difficult to remove.
