Instructions for use |
Surface preparationCheck that gutters are in good working order, that walls and floor meeting corner sides are rounded, and verify minimum slopes of 1.5%. Concrete substrate will be casted minimum 30 days before application. Remove intensively all loose particles. Rinse intensively the roof/deck to remove mud and wait until completely dry. Application temperatures: 7ºc - 35ºc (convenient temperatures: 15ºc - 27ºc).
Performing of the sealing system
Waterproofing system for exposed roofs:
For long term and qualified roofing system : On substrates such as concrete, old bitumen membranes with aggregates, old PU and acrylic coatings - apply Aquapoxy, 250 gm/m², wait 1-2 hours for initial drying. On metal substrate, apply Polyseal Primer, 150 gm/m², wait 3-4 hours for initial drying.
On rough surfaces, you should expect bigger quantities.
