Self-adhesive modified bituminous Waterproofing Membrane Product Storage Prior to Use

Avoid storing unprotected self-adhesive products in direct sunlight, as UV exposure can weaken the adhesive properties, especially on the outer layers, or cause the roll to “dog-leg.”Prolonged storage or exposure to extreme conditions may also modify the adhesion properties of the self-adhesive bitumen or disrupt the alignment of the rolls.
