MEM DACHLACK lmf is a black, water-repellent, latex-bitumen-based top coat for the protection and care of weathered, brittle and slightly brittle bitumen roofing membranes. MEM ROOF LACK lmf has high opacity.
Properties / Applications
MEM DACHLACK is a black, water-repellent, bitumen-based top coat to protect and care for weathered, worn-out and slightly brittle bitumen roofing membranes. MEM roof paint has a high opacity.
mode of action
MEM ROOF VARNISH dries to form a seamless, water-repellent, film-like coating. The coating does not become brittle and is resistant to naturally occurring substances that are aggressive to concrete.
substrate and processing
MEM DACHLACK is suitable for the protection, care and regeneration of weathered, brittle and slightly brittle bitumen roofing membranes (not suitable for plastic roofing membranes).
MEM ROOF VARNISH dries to form a seamless, water-repellent, film-like coating. The coating does not become brittle and is resistant to naturally occurring substances that are aggressive to concrete.
The substrate must be firm, stable, clean, largely level and free of cracks, nests of gravel, etc. and residues of oil, grease, dust or other separating layers.
The substrate may be slightly damp without a visible film. The treated surfaces must not be permanently wet, as then no thorough drying can take place.
Stir MEM DACH LACK well before use. Highly absorbent substrates may need to be primed with MEM PRE-COAT.
After drying, MEM DACHLACK is applied in 2 to 3 layers with a roller, brush or suitable spraying device, whereby each layer must be completely dry before further processing.
In areas at risk of cracking, a reinforcement fabric, e.g. MEM PANZERVLIES, should be worked into the second layer.
Avoid direct sunlight during processing. Rain during processing or drying can cause damage (e.g. rinsing).
