BUILDPLAST-PJS POUR GRADE is a high performance. self leveling chemical resistant elastomeric joint system. Due to its high polysulphide polymer content, it is resistant to many chemicals. shrinkage, aging, thermal stress and the effects of outdoor exposure. It is highly resilient and has excellent recovery characteristic after extended period of compression or elongation.
4 x 4 kg in a carton and 4 x 6 kg in a carton. Shelf life is 12 months from date of manufacturing in unopened condition.
Joint surface to be applied should be clean dry and free from loose material, dust oil or
