HIGH FLOW, EASY TROWELLING SMOOTHING COMPOUND
Bostik SL C540 FLOW is a two-part cementitious underlayment with an improved flow for smoothing and levelling uneven floors before laying decorative floor coverings. It has excellent workability and flow, is self-smoothing and can be trowelled to a feather edge. Bostik SL C540 FLOW can be applied over most common substrates, including concrete, sand/cement screeds, stone, anhydrite screeds, terrazzo & quarry tiles, asphalt and other solid and rigid subfloors. Bostik SL C540 FLOW should not be used over adhesive residues. As Bostik SL C540 FLOW is protein-free, it is suitable for biologically sensitive areas. The low-odour formulation makes it ideal for use in occupied buildings. The moisture tolerant formula enables Bostik SL C540 FLOW to be used to smooth rough-textured subfloors before the application of Bostik damp proof membranes in buildings incorporating a base DPM. It is suitable for use with warm water underfloor heating systems, provided a surface temperature of +27°C is not exceeded and in areas of high solar gain. It is not to be used as a wearing surface and should always be covered with a floor covering. For interior use only.
