To complete this system of waterproofing of shower walls, Profilpas also offers internal and external corners, stripe and collar for sealing. If you need to waterproof the junctions and the connections between the membrane and special pieces, Profilpas recommends to use a polymer sealant MS (PP/96) at the extremity and to superimpose the special piece on the membrane of almost 5 cm. Conversely, near perimetral junctions and expansion joints, you should use a 14-cm-wide stripe between the two cloths, glued on both sides with polymer sealant MS (PP/96).
