SELF-LEVELLING SCREED

Decorative self-levelling, self-smoothing and quick setting screed for new and old concrete floors

Self-Levelling Screed is a polymer modified cement base screed with very good properties such as low shrinkage and high adhesion strength for pedestrian traffic.

Suitable for interior or exterior use as an underlayment or overlayment. It’s high strength and excellent durability can be further enhanced by further enhanced by adding FLEXTILE 43 LATEX additive.

ADVANTAGES OF USING SELF-LEVELLING SCREED

· Fluid consistance ensure product levels to a smooth even surface

· Minimum shrinkage to cracking and spalling

· Hogh early strength

· Quick setting

· Excellent bond strength to concrete substrates

· Can be laid in thickness of 1 - 30 mm

· Contains synthetic fibres

· Fast and easy installation resulting in reduce labour costs

· Can be mixed with FLEXTILE 43 latex Additive for even higher strength and abrasion resistance
