• Apply 2-3 coats using a brush or roller

B. Waterproofing for Horizontal Surfaces
• Mix 4 liters of DAVIES® MORTAFLEX® to 5.5 kg of ordinary Portland cement and 3 kg of sand.
• Apply one (1) coat using a trowel

C. Floor Patching & Concrete Repair
• Mix 4 liters of DAVIES® MORTAFLEX® to 7 kg of ordinary Portland cement and 7 kg of sand.
• Apply one (1) coat using a trowel

It is not recommended for the interior face of the structure (negative side).

Drying Time:
Dry to touch- 10-15 minutes
Flash-off (in between coats): 30 minutes
Dry hard (paint-ready): 3 days

Clean-Up: Clean water

STORAGE AND HANDLING
