- GENERAL APPLICATION INSTRUCTIONS
Apply ELASTAFLEX™ HP only to clean, dry, sound, surfaces free of loose particles or other foreign matter. ELASTAFLEX™ HP can be sprayed over a broad range of ambient and substrate temperatures. It is recommended that ELASTAFLEX™ HP be sprayed in multi-directional (north/south - east/west) passes to ensure uniform thickness.
COMMON SUBSTRATES:
STEEL: 4-5 mil anchor profile is best for maximum adhesion andvaries per application and conditions; adhere to proper SSPC standards.
WOOD: Apply polyurea onto a clean, dry, and sanded surface; free from burrs, splinters and loose debris. (It is recommended to prime wood and other porous surfaces before application of heated, fast-set polyureas to reduce pin holing).
CONCRETE: Prepare concrete in accordance with SSPC/NACE Standards and SPI Concrete Prep Guide.
NOTE: It is recommended that existing surfaces be powerwashed with 2500—3500 psi water pressure to enhanceadhesion of ELASTAFLEX™ HP. If there is a possibility ofsurface contamination, scrub with a solution of 1/4 tsp Dawn detergent and 1 tbsp of vinegar, per 1 gallon of warm water. Follow with a thorough water rinse. If there is oxidation onthe surface of the existing substrate; it must be removed prior to application of ELASTAFLEX™ HP. Removal of oxidation can be done via mechanical methods to insure the ELASTAFLEX™ HP has a sound substrate to adhere to. The use of SPI Prep Wipe™ solution will tack up the existing polyurea coating andhelp promote bonding of the ELASTAFLEX™ HP.

Technical Details & Test Data
- Applications & Uses
Thoroughly agitate the “B” components of this product prior to application. Use a SPI folding blade mixer or equivalent equipment approved by SPI. Install mixer through the extra air specific 2” bung hole provided on all “B” drums. Care must be taken not to cross contaminate the individual components with the mixing equipment; for best mixing results, supply the SPI mixer with 25 cfm of air at 100 psi. Thinning is not required. Using any thinner may adversely affect product performance.

EQUIP & MFGBoss - Standard 1:1 ratio, heated, plural-component equipment developing a minimum of 2000 psi (10.4 MPa) dynamic pressure at the gun with heating capabilities to 175°F(79°C) will adequately spray ELASTAFLEX™ HP.
- Machines capable of producing a higher dynamic psimay be required depending on the service environment the ELASTAFLEX™ HP will be exposed to.
- Proportioning machine primary heater temperature 160-170°F (71-77°C).
- Hose temperature 160-170°F (71-76°C). A hose thermometer inserted under the insulation near the gun should read a minimum of 145-155°F (63-68°C).
- Physical properties will be enhanced when sprayed at higher pressure (3000 psi or more); and utilizing an impingement mix gun such as MP Fusion or GX7-DI gun.
- Do not use mixing chambers with output greater than 1.5 gallons per minute.
- LIMITATIONS
- ELASTAFLEX™ HP is for professional use only. User must be proficient in the application of ELASTAFLEX™ HP and the use of the high pressure heated plural component equipment used to apply it.
- ELASTAFLEX™ HP must be stored at temperatures between 60—90°F (15—32°C).
- Liquid temperature in containers/drums during application 70—100°F (21—38°C).
- Apply ELASTAFLEX™ HP when surface and air temperatures are above 40°F (5°C) and the surface temperature is at least 5°F (3°C) above dew point and rising.
- Avoid moisture contamination in containers. Containers should not be resealed if contamination is suspected.CO2 created pressure can develop. Do not attempt to use contaminated material.
- Undried air exposed to liquid components will reduce physical properties of the cured coating.
Note: The material supplied is a two component system(component “A”/component “B”, which is used to formulatethis product. The quality and characteristics of the finishedpolymer is determined by the mixture and application of thetwo components by the person applying the polymers.
