VI-CRYL® CP-10/11 weather barrier coating is unsurpassed for the mechanical protection and weatherproofing of thermal insulation both outdoors and indoors in hot, cold and dual-temperature service.
Childers VI-CRYL CP-10/11 weather barrier coating is a durable water based vinyl-acrylic mastic coating for thermal insulations. CP-10/11 is a tough, durable, and fire-resistive water based mastic for most types of thermal insulation and finishing and insulating cements. It is very thixotropic – it looks heavy but spreads easily. It is available in a variety of standard and special fade-resistant colors. It is outdoor rated and U.V. resistant. It comes in two grades for trowel application (CP-10) or spray / brush application (CP-11).
VI-CRYL® CP-10/11 weather barrier coating is unsurpassed for the mechanical protection and weatherproofing of thermal insulation both outdoors and indoors in hot, cold and dual-temperature service. However, since it is a ‘breather’ coating (vapors under pressure will pass through it), it should only be used over insulations in low temperature or dual-temperature service when the insulations themselves are vapor barriers. VI-CRYL® CP-10/11 has also found use throughout the thermal insulation industry as a coating used over closed cell polyethylene and polyurethane foam insulation. Industry experience has demonstrated that all weather barrier coatings may blister when applied over polystyrene board, but may be limited by use of white colored coatings. VI-CRYL® CP-10/11 weather barrier coating in its metallic gray color is the ideal companion product to aluminum and stainless steel jacketing.

1. Use Of Material
VI-CRYL® CP-10/11 weather barrier coating looks much heavier than it is. It is thixotropic. DO NOT THIN. Protect from freezing until dry. Keep stored over long periods of time in a heated area. For spray application, VI-CRYL® CP-10/11 coating must be kept at a minimum of 50°F (10°C) just prior to spraying to achieve optimum results.
2. The Condition Of Insulation To Be Coated
VI-CRYL® CP-10/11 is a “breather coating”, which means that it will allow reasonable amounts of water (in the form of vapor – a gas) to pass through it in a reasonable period of time. However, excessively wet insulation on equipment operating at elevated temperatures will cause excessive water vapor pressure, and therefore blistering of the finish. Make certain the insulation is dry prior to the application of any coating. To obtain proper bonding, dusty surfaces shall first be primed with Chil-Seal® CP-50A MV1 diluted 50% with water. When applying VI-CRYL® CP-10/11 coating over hygroscopic alkaline cements, first prime the surface of the cement with Chil-Seal® CP-50A MV1 diluted 50% with water and allow to dry completely before applying the finish coat. The presence of moisture in systems operating in cold service can completely destroy the effectiveness of not only the finish, but the entire insulation system. They MUST BE DRY. All exterior horizontal surfaces must be sloped at least 1/2 inch per foot (4 cm/m) to prevent ponding water.
3. Hand Application
Large flat areas are best covered by application with trowel or stiff brush. Smaller, irregular surfaces such as fittings are more readily covered by brushing. Airless spray may also be used.
4. Spray Application
VI-CRYL® CP-10/11 may be sprayed with many types of equipment, including airless spray. It may also be sprayed with conventional mastic spray equipment using an external atomizing spray gun. Many manufacturers of spray equipment can make detailed recommendations for any number of types of equipment. The spray equipment and techniques would be similar to those used for applying block fillers. For best results, we suggest at a minimum the following airless spray equipment (see spray equipment dealer for available packages): PUMP Graco Checkmate pump, 40:1 on 100cc lower, NXT2200 motor mounted on ram plate, Graco S20C – 5 gallon cart mounted ram COMPRESSOR Capable of 75 CFM and maintaining 100 PSIG FLUID HOSE High pressure capable of 4,000 PSI ½” inch up to 50 feet. 3/4 inch over 50 feet. Use 8’ x 1/2” I.D. hose for coupling to the gun. A higher ratio pump set-up will allow for longer hose runs up to 150’ GUN Graco Mastic or textured coating spray guns with Reverse-A-Clean tips TIP SIZES 635 to 655 Most manufacturers of mastic spray equipment maintain nearby service facilities to aid in the solution of any technical problems that arise with their equipment.
5. Drying And Recoating
A finish coat of VI-CRYL® CP-10/11 should be applied immediately after the tack coat and membrane application for maximum bond.
