Important Notes
- Substrate must be sound, dry, clean and free from oil and removable contaminants
- Porous or open-textured substrates require primer (diluted RTU 801 or Sikalastic-500 Acrylic Primer HK)
- Fresh concrete must be fully cured before application
- Allow substrate to dry thoroughly after rain
- Reinforce open joints, corners and stress points with fibre-reinforced detail coats
- Slight separation after storage is normal — stir at low speed to restore uniformity
- Clean tools immediately with water
- For detailed application methods, coverage rates and technical parameters, refer to the official product data sheet
FAQ
How does Monoprufe RTU 801 differ from standard roof waterproof coatings?
Polyurethane-acrylic copolymer formulation with elongation far exceeding standard acrylic coatings. High elasticity effectively bridges cracks and accommodates movement. UV-resistant and non-yellowing — ideal for exposed roofs and walls.
Is a primer required?
For porous or open-textured concrete and mortar substrates, apply primer (diluted RTU 801 or Sikalastic-500 Acrylic Primer HK). Smooth non-porous substrates can be coated directly.
