Processing guideline


The materials used must be free from dust and grease and substrates must be dry and supporting.
The greater the pressure applied, the better the performance of the adhesive tape.
Sealing Plaster has the function of sealant and not of a firm connector (No permanent tensile stresses may act on the bonded joints – e.g. if the drill cores of OSB boards are re-inserted, they must be mechanically fixed). The pure acrylate adhesive used does not contain resins or other additives that could cause the adhesive film to become brittle and therefore this product is extremely resistant to ageing.
