The character of Idraflex.
A high-elastomeric polymer-cement (or single-/two-component polymer) waterproof coating engineered for residential wet zones and small commercial works. Designed for domestic kitchen, bathroom and balcony waterproofing at home, and humid-climate residential plus light-commercial projects abroad.
High-elongation membrane
Elongation at break ≥300%: bridges hairline cracks and substrate movement that rigid waterproofing fails on.
Tested watertightness
0.3 MPa for 30 min with no leakage: meets residential and light-commercial waterproofing acceptance.
Finish-compatible
Bonds with tile adhesive, microcement and decorative coating systems: no awkward interface trades.
Predictable wet-zone trade
Fixed system thickness and coverage make take-off pricing and warranty terms predictable for project teams.
