STORAGE
STABILITY:
One year from date of manufacture when stored in sealed container below 75F (24C).
THINNER & CLEANER:
Gaco Western's T-5129 thinner. Only use thinner supplied by Gaco Western.
APPLICATION
PRIMER:
None normally required.
MIXING:
Mix before application to assure uniform color and consistency.
APPLICATION:
Apply by brush or roller as received. Thinning up to one pint per gallon (.47 L) is permissible if viscosity increases. For spray application, use as received. For cold weather application, keep material stored above 65F (18C). 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-5129 thinner. Recirculate through lines and gun until residual Gacosil is removed.
CURE:
Applied coating will cure in 3- 7 hours depending on temperature and humidity.
CAUTION:
Gacosil S-10 contains solvent and is flammable. Keep away from heat, sparks and open flame. Avoid prolonged breathing of vapors and prolonged or repeated skin contact. Use only with adequate ventilation.
