ReadElastomeric Waterproof Coatings
Flexible reinforced waterproof coating for structures under sustained water pressure, showing nil water penetration at a 50-metre water column and bridging cracks up to 3.5 mm.
ROOFBOND RFX PLUS 210 is a high-performance flexible reinforced waterproof coating engineered for structures under sustained water pressure. It delivers 5–5.5 N/mm² tensile strength with 120%+ elongation, bridges cracks up to 3.5mm and shows zero water penetration at a 50-metre water column, with a bond strength of 2.0 N/mm² to prepared concrete and a stated durability of 10+ years.
Figures are controlled laboratory results. Actual site performance varies with substrate, temperature, humidity, application method and workmanship — please confirm the current product datasheet before specification.
ROOFBOND RFX PLUS 210 is a waterproofing for basement under water pressure, made as a flexible reinforced coating for structures that stay in contact with water. The components are mixed to a smooth, lump-free slurry and applied in two coats by brush, roller or spray. Fibre mesh or geo fabric can be embedded in the first wet coat for extra reinforcement.
Applied where hydrostatic pressure on the structure is continuous.
Nil water penetration at a 50-metre water column suits stored water.
Two coats by brush, roller or spray over the prepared slab.
Used in pits and sunken slabs where water pressure is sustained.
Water cure for 7 days before flood testing the pool.
Flexible coating that bridges cracks up to 3.5 mm underground.
Where lift pit leakage or basement seepage comes from continuous water pressure, the figures matter. The coating shows nil water penetration at a 50 m water column, which is why it is used for hydrostatic pressure waterproofing. Tensile strength is 5–5.5 N/mm², elongation 120%+, crack bridging up to 3.5 mm and bond strength 2.0 N/mm² to prepared concrete. Coverage is 13–14 sq.m per 20.1 kg unit, with a stated durability of 10+ years. Water cure for 7 days before flood testing or covering.
Armstrong Chemicals supplies ROOFBOND RFX PLUS 210 to sites across Telangana, Andhra Pradesh, Karnataka, Kerala and Tamil Nadu, including Hyderabad, Vijayawada, Bengaluru, Kochi and Chennai.
Zero water penetration at a 50-metre water column means the coating keeps holding when water presses on it continuously.
With 120%+ elongation and crack bridging up to 3.5 mm, the film can stretch across cracks instead of splitting.
A bond strength of 2.0 N/mm² to prepared concrete keeps the coating attached to the surface it protects.
Clean and prepare the surface — remove all loose material, laitance, dust, oil and fungal growth
Pre-wet the substrate to a saturated surface-dry condition, leaving no standing water
Mix the components thoroughly to a smooth, lump-free slurry
Apply the first coat by brush, roller or spray over the entire prepared area
Apply the second coat perpendicular to the first once the first has set firm
Embed fibre mesh or geo fabric in the first wet coat where extra reinforcement is required
Water cure for 7 days before flood testing or covering
