When to Choose CL 71?

If your roof is covered with moss, algae, or a green film, or if you want to prepare it before applying a renovation coat. A clean surface is the foundation for the long-lasting results of any renovation.

Recommendations

For heavily soiled roofs, we recommend first removing coarse debris with a high-pressure washer and then applying CL 71 as a concentrate. For maximum renovation longevity, apply HYDROPROTECT after cleaning; this helps extend surface protection for up to 15–17 years. After application, it is important to protect the surface from rain for at least 24 hours.
