High performance, two-part cementitious underlayment.
Suitable for use over most adhesive residues.
Bostik SL C955 ADVANCED is a high performance, two-part cementitious underlayment which offers excellent adhesion on most subfloors without priming. It is particularly suitable for use over old adhesive residues (including bitumen and carpet tile tackifiers).
Bostik SL C955 ADVANCED smooths and levels subfloors prior to installing all types of floor coverings. It can be applied over most common substrates including: old bitumen, ceramic tiles, flooring grade plywood, concrete, sand/cement screeds, stone, rigid metal, terrazzo (take care to degrease and prepare surface), quarry tiles, asphalt and other strong, rigid subfloors.
It is suitable for use where low-odour products are required. Bostik SL C955 ADVANCED is specially formulated to be used in conjunction with waterborne underfloor heating systems and can also be used to encapsulate electric cable type heating. Due to its high adhesion and low shrinkage properties, it can be used without a primer onto most substrates in both domestic and commercial locations.
Bostik SL C955 ADVANCED is suitable for refurbishment projects and may be applied onto firmly bonded thermoplastic tiles which have been installed on bituminous adhesives. Tiles must be stable, clean and degreased.
