Bostik Cempolatex Flexi-Deep is a protein-free, flexible smoothing compound for preparing interior floors prior to laying carpet, soft floor coverings or ceramic tiles. It is reinforced with fibres for strength and flexibility and can be applied to depths between 3mm and 60mm in a single application. Being protein-free, it is suitable for use in biologically sensitive areas.| |Bostik Cempolatex Flexi-Deep has excellent workability and is ideal for smoothing and levelling prepared concrete subfloors, sand/cement screeds, calcium sulphate screeds, rigid timber floors and other strong rigid subfloors. It can also be applied over minimal quantities of tile adhesive residue, provided they are firmly bonded and unaffected by water.|It is suitable for use with warm water underfloor heating systems and for encapsulating electrical radiant heating mats, provided a surface temperature of +27°C is not exceeded. It is not to be used as a wearing surface and should always be covered with a floor covering. For interior use only.
