Flexible Cementitious Based Waterproofing Coating
DESCRIPTION
Two-component acrylic polymer modified cementitious coating, which consists of specially selected cements, well-graded fine aggregates and additives supplied in powder form together with a liquid component of acrylic polymer, pre-dosed, ready for use as waterproofing slurry.
USES
For external and internal waterproofing coating, crack sealing on concrete, mortar, brickwork, in basements, swimming pools, water tanks, flat roofs, balconies, terraces, retaining walls, sea walls, tunnels, etc.
ADVANTAGES
- Can be applied to wet or damp substrate
- Good adhesion to substrate
- Flexible, elastomeric properties will be able to bridge cracks
- Fast curing, will allow for foot traffic when cured
COVERAGE
Depending on type of application, 2 coats are always required.
Waterproofing for toilet or bathroom : 1.25 kg/m2 at 0.7 mm of thickness.
Waterproofing for swimming pool or reservoir : 2.5 kg/m2 at 1.4 mm of thickness.
INTRUCTIONS FOR USE
The concrete surface should be sound, clean, free of oil, grease, dust or laitance and saturated surface dry. Then pour half of component A (liquid) into mixing vessel, then add all of component B (powder) and mix until you have slurry of uniform consistency.
Add rest of component A and mix again until you have uniform, lump-free mixture.
For mixing, a mechanical slow speed mixer is recommended with mixing time of 2-3 minutes, if Deltaproof CB is to be applied by trowel, use only 90% of liquid component.

Application
Always apply a minimum of two coats, the first coat on the still damp, pre-wetted substrate. The second coat is to be applied after the first coat has started to set and can support the following coat, usually after 2-6 hours, depending on climate.

HEALTH AND SAFETY
Deltaproof CB Flex powder component contains cement powders which, when mixed with the liquid, release alkalis which can be harmful to the skin. During use, avoid inhalation of the dust and contact with the skin or eyes. Wear suitable protective clothing – eye protection, gloves and respiratory equipment, particularly in confined spaces.
