General notes
- Limits of use: do not use in food industry facilities.
- The solvents must have fully evaporated before laying hot-welded bitumen membranes or cold-applied bitumen felts.
- In case of application on non-ferrous metals (e.g. aluminum, copper or zinc), a full-cover with weber.tec 902 must be achieved; after drying repeat this operation to avoid pinholes.
- Prevent from strong sunlight.
- Higher temperatures and lower humidity rates accelerate, whilst lower temperatures and higher humidity rates delay drying.
- Observe the national regulations for working with solvent-based products.
Special notes
- Do not add any foreign substances during application.
