Description
An acrylic-based liquid roof-waterproofing material.
Properties
Developed for waterproofing and especially roof insulation. Its semi-fluid nature coats surfaces easily. Water-vapour permeable, letting moisture escape. 600% elastic; retains elasticity through hot/cold swings. Tensile strength after 24 h at 23 °C is 25 kg/cm². High chemical and UV resistance, excellent adhesion, waterproof and decorative.
Application area
Safely used where water/moisture-proofing is needed — concrete, plaster, brick, ytong, briquette, eternit, wood, and corrugated/flat asbestos roof sheets.
Application method
Prep — free surfaces of all adhesion-blocking oil, dirt and loose layers; make clean and dry. Before applying, thin Universal Aqua Stop 40% with water and apply one coat as primer; once dry, apply 2–3 coats unthinned. Apply each coat crosswise to the previous, within at least 24 h. Surfaces that will be walked on or subject to mechanical impact need a protective topcoat.
