Details of different surfaces
All bitumen surfaces must be fully dry. Ensure asphalts are pressure washed clean and free of any loose particles including moss, algae growth, etc. Applying the Lava 20 membrane over any uncured (not aged) asphalt products will result in staining/blistering.
The use of geotextile matting is required for all bitumen-based materials over the entire surface. The Lava 20 system is designed to cover o
For newly set concrete structures, at least 28 days curing time is required before applying Lava 20. Both new and existing concrete surfaces must be completely dry prior to application. Oil, grease, curing compounds, loose particles, moss, algae growth, laitance, friable matter, dirt, bituminous products, and previous water proofing materials must be removed.
All metal/steel surfaces must be thoroughly cleaned and dried prior to application. Rust (iron oxide) is the result of oxygen and water or excessive moisture on metal surfaces. All rust areas must be treated before using Lava 20 Quick Primer.

Application Tools & Materials Required
Coating over wet wood/plywood surfaces will greatly reduce Lava 20 membrane adhesion.
System can be spread out on wood/plywood surfaces using a roller, brush, squeegee, or airless spray. The use of polyester fabric matting for reinforcement is recommended.
It is recommended to conduct an adhesion test for extremely durable synthetic rubber roofing membranes (EPDM) and single-ply Thermoplastic Polyolefin (TPO) substrates in order to ensure the best adhesion possible.
