APPLICATION

PRIMER

None normally required.

MIXING

Mix before application to assure uniform color and consistency.

APPLICATION

Apply by brush or roller as received. For spray application, use as received. Consult Gaco Western's Silicone Spray Guide SG-Silicone for more information.

For cold weather application, keep material stored above 65° F (18° C). Maximum time between coats is 72 hours. Longer recoat times will result in poor intercoat adhesion and delamination.

CLEAN-UP

Clean spray equipment with GacoFlex T-5135 thinner. Recirculate through lines and gun until residual GacoSil is removed.

CURE

Applied coating will cure in 3 to 7 hour depending on temperature and humidity.

CAUTION

GacoSil S-10 contains solvent and is combustible. Keep away from heat, sparks and open flame. Avoid prolonged breathing of vapors and prolonged or repeated skin contact. Use only with adequate ventilation.
