ABAFLEX-FCW
HIGHLY FLEXIBLE CEMENTITIOUS WATERPROOFING MEMBRANE FOR HORIZONTAL & VERTICAL SURFACES
DESCRIPTION
A two part acrylic polymer modified highly flexible cementitious waterproof membrane supplied in pre-packaged form for the protection of concrete and mortar. ABAFLEX-FCW provides excellent adhesion, flexibility, crack bridging ability, and durability.
SURFACE PREPARATION
The substrate should be clean and sound, free of dust, loose particles, grease, oil and primers from previous membrane systems or bitumen. Bitumen or primers should be removed by shot
blasting or mechanical means. Spalled concrete should be repaired by cutting out to sound concrete and patching with E.M.SUPER REPAIR .Cracks, holes and honeycombs must be repaired prior to application.
MIXING
ABAFLEX-FCW is supplied in premeasured units. Slowly add the powder to the liquid and mix to a lump free smooth consistency. Do not add water or rework a stiffened mix by adding water. Mix sufficient material to use within 30 minutes.
APPLICATION
Saturate the concrete’s surface with clean water. Apply the first coat while the surface is still damp but no free standing water. Apply using a short stiff bristle brush, rubber squeegee or roller at a rate of 1-2 mm. for walls and floors, depending on the expected water pressure. The required thickness is achieved by applying 2 layers, taking care that each layer is not thicker than 1mm. Leave the first coat to dry for 2-4 hours before applying the second coat. The second coat can be rubbed down with a soft dry sponge. Spray or trowel application is acceptable providing the mixing ratio is adjusted to achieve the right consistency. Leave the second coat of ABAFLEX-FCW to cure overnight before proceeding to conduct water ponding test.
CURING
ABAFLEX-FCW should be protected from high wind & intense sunshine. Keep moist for 3 - 4 days after application.
ADVANTAGES
• Resists strong hydrostatic pressure (tested against strong water pressure head both positive and negative)
• Solvent free and non-toxic - Environmentally friendly
• Protection against carbonation and chlorides
• Excellent adhesion. Full bonded
• Bridges cracks on positive water pressure side applications
• Minimum surface preparation needed. No priming is necessary in most cases.
• Stands up to pedestrian and light traffic
• Resists abrasion, mechanical wear & deicing salts
• Applied to moist/damp substrates. (Also it can be applied to 24 hour old concrete.)
• Approved for use in contact with potable water
• Breathable (not a vapor barrier)
• Does not support the growth of mold & mildew
• UV resistant
FIELD OF APPLICATION
Coatings made of ABAFLEX-FCW are wear-proof, elastic and waterproof. Such coatings can be used for areas subject to mechanical stresses and for areas which might be subject to cracking, e.g. waterproofing layers on terraces and balconies, as protection for concrete surfaces which can be walked on, as waterproofing for water tanks, swimming pools, underground concrete structures, pits, basins, wet and damp-rooms underneath tiles and ceramic coverings.
