The POLITABER AUTOADHESIVA ABT GRIS is a waterproofing membrane, easy to lay designed for pitched roof systems or wood pergolas. The top surface of grey mineral slate chippings provides an aesthetical decoration and a protection against moisture and rain.


Clean the surface and prime it with a coat of ChovASTAR Preparador de Superficies. Start installing the membrane in upwards direction, from the bottom of the roof up to the top. Make 10 cm overlaps and press the area with a roller for a perfect sealing. Full laying instructions are provided within each box. In case of doubt as to the installation, please, revert to our Technical Department.
