Two-component, solvent-free, low-viscosity, elastic and impact-resistant polyurethane primer and binder, suitable for bituminous and mineral substrates, compatible with DANOCOAT® and DANOPUR® systems.
Instruction for Use
- Before applying the product, check that the application surface is dry, clean and free of solid debris and irregularities.
- Protect yourself adequately for handling the components with appropriate gloves and mask. See safety data sheet.
- Mix the two components in the plastic container to a uniform mass.
- Apply to cracks and joints first. We recommend using 4×4 mm fibreglass reinforcement (PX160 mesh).
- Use a trowel/roller to apply the first coat and place in fresh PX160 Mesh reinforcement also in the corners.
- Apply the remaining coats crosswise to the previous coat for best result (see Drying Time).
