WELD-ON® Pool Primer
WELD-ON® Pool Primer is a low VOC emission, non-bodied, fast acting, primer. The strong action of Pool Primer rapidly softens and dissolves the joining surfaces of PVC pipe and fittings. Available in clear and purple; the latter allows easy identification when used on the joining surfaces.
WELD-ON Pool Primer, when used in conjunction with appropriate WELD-ON Pool & Spa solvent cements, will make consistently strong, well-fused joints. It is essential that the joining surfaces of pipe and fittings be softened and remains softened prior to assembly. The main function of the primer is to expedite the penetration and softening of the surfaces. Its rate of penetration into the joining surfaces is more rapid than that of solvent cement alone. Pool Primer is suitable for use with all types, classes and schedules of PVC pipe and fittings.
Detailed directions on making solvent cemented joints are printed on the container label.
NOTE: WELD-ON solvent cements must never be used in a PVC system using or being tested by compressed air or gases; including air-over-water booster.
