This GRC PU promenade tile adhesive from Castle Composites has been designed to adhere GRC tiles to a multitude of surfaces, from bituminous felt roofs, sanded asphalt and almost all other flat roof surfaces.
Created with strength and reliability in mind, the adhesive absorbs moisture from the atmosphere and expands providing a firm support to the tile. This highly effective fixing method, when cured retains a degree of flexibility which allows for thermal and structural movement of the tiles and roof that other cementitious tile adhesives do not.
Pack Quantity: 1 litre bottle
Coverage: 50 tiles or 5m² approx.
Please note: If too much adhesive is used or has been applied too close to the edge, the expanding action will force the foamed adhesive up through the gaps between tiles. Do not try to remove when wet, simply leave until dry and then carefully cut off with a craft knife and remove marks with wire wool.
