Sealacryl provides immediate waterproofing for emergency roof repairs, even on damp surfaces.

What you’ll need

  • Remove dirt, debris, moss and loose material from the area.

  • Remove standing water where possible.

  • Fill large gaps with bitumen mastic if required.

2. Application

  • Stir Sealacryl thoroughly.

  • Apply a thick, even coat over the repair area, working into cracks.

  • Reinforce with scrim if the area is subject to movement.

3. Curing

  • Provides instant waterproofing.

  • Touch dry in 6–8 hours and fully cured in 24–48 hours.

  • Apply a second coat after 2–3 days if required.

Key tips
