QTP® 4571 — highly elastic membrane under polymer floors
Polymer-hybrid composition with 700 % elongation — a membrane under rigid coatings, a chemical-resistant sealant and waterproofing.

This clear binder with a glass-like surface effect is designed for coatings based on coloured quartz sand. It works as a clear self-levelling finish and as a binder for slip-resistant and highly filled decorative systems. Compressive strength reaches 83 MPa, flexural strength 79 MPa and Shore D hardness 84. The kit weighs 12.8 kg; at +20 °C, foot traffic is possible after 18 h.
