Dunlop Wall and Floor Tile Adhesive is specially formulated to suit most tiles including ceramic, porcelain, mosaics, fully vitrified and natural stone (excluding moisture sensitive stone). It is suitable for use over many different surfaces including timber (indoors) as well as fibre cement sheets, concrete and plasterboard where surfaces are subject to thermal and shrinkage movement. The adhesive can be used indoors (including showers) and outdoors provided there is no standing water and there is a sufficient fall achieved in installation for water run off.
