Description

Dur-A-Seal XL 250 Clear Acrylic Concrete & Masonry Sealer is a one-component, clear xylene-based, acrylic copolymer sealer.

Advantages
  • Extremely resistant to weathering effects and provides a uniform, easy-to-clean surface for walls and floors.
  • Breathable coating; liquid water will not pass through the coating but water vapour can vent to the atmosphere within the coated surface.
  • Resistant to a wide range of weak acidic and alkaline solutions.
  • Good inter-coat adhesion allows for repair and re-coating after cleaning.
Uses

Dur-A-Seal XL 250 is used primarily to seal  Art-I-Stone when the application is carried out on exterior surfaces, both vertical and horizontal. It effectively seals against the ingress of water and it protects the colour and texture of the Art-I-Stone. Its superior wear resistance and ability to withstand chlorides make it ideally suited for protection of exterior pedestrian traffic areas such as walkways, concrete decks, verandas, stairs, and pool decks.
