Liquid waterproofing membranes are liquid, applied like paint or spray, etc., which take the form of highly flexible (very high elongation) monolithic (jointless) membranes with excellent waterproofing capabilities. We have developed liquid-applied waterproofing membranes, such as polyurethane waterproofing and sealing membrane, polyurea membrane, hybrid polyurea membrane &, etc., from numerous compounds to fix the leakages.

Apply ELASTOROOF 2K directly to the primed concrete surface in good condition.
Apply 1.5-2.6 kg per sq. m. in two coats.
First coat: Use a brush, roller, airless spray, or squeegee. Apply 1-1.3 kg per sq. m. and let it cure overnight.
Second coat: Apply 0.5-1.3 kg per sq. m. using a brush, squeegee, or airless spray.
Cure for 12-24 hours. Broadcast nonslip aggregate on the wet second coat.
Ideally, perform hydro-testing for at least 72 hours to ensure membrane integrity.
After testing, protect the membrane with a cement-sand dash coat before installing tiles/another surfacing. Alternatively, limit foot traffic on the exposed membrane.
General water isolation: Water tanks, pools, swimming pools, ponds, pipes, pipelines, waste water treatments, manholes, and sewer linings.
Floors: Industrial floors, hospitals, factories, parking lots, and garages.
Truck bed liners.
Construction: Roads, bridge decks, railways, high-speed railways, tunnels, airports, and line striping.
Marine industry and marine applications.
High abrasion applications: Oil and gas industry, refineries, petrochemical industry, mining, secondary containment, and energy industry.
Leisure industry: Water parks, aquarium linings, playgrounds, theme parks, and decorative applications.

FLEXITOP POLYUREA is sprayed using a 1:1 volume ratio with airless spray equipment.
Choose the appropriate primer based on substrate and weather conditions. Allow it to cure as directed.
Follow the start-up procedure for the airless spray equipment.
Test spray surface for compatibility.
Apply the first coat and the second one in the opposite direction using the cross-hatch technique. Each coat should have a typical thickness of 1.5 mm to 3 mm.
FLEXITOP POLYUREA coating achieves handling strength within 20 to 30 minutes.
Liquid-applied waterproofing is a method used to protect various surfaces from water and moisture damage. It involves applying a liquid-based coating, typically made from polymers like polyurethane or acrylics, directly onto the surface. This coating dries or cures to form a seamless, flexible, and durable waterproof barrier. This method is favored as it is joint free, is able to adapt to surface irregularities and undulations, for its adaptability, strong adherence, and effectiveness in providing long-lasting water-resisting protection.
The best liquid membrane waterproofing depends on the specific requirements of the project, including the type of surface being treated, environmental conditions, and desired durability. However, some of the best ones are SUNPROOF PU 1K, polyurethane waterproofing membrane, SUNKOTE WP+ single component elastomeric waterproofing membrane, POLYALK WP polymeric cementitious waterproof coating, etc.
Yes, a liquid waterproofing membrane is highly effective for protecting various surfaces from water damage. It offers seamless coverage, ensuring no gaps or weak points that can occur with sheet materials. The flexibility of these membranes allows them to adapt to structural movements and temperature changes, preventing cracks. Easy to apply, they are ideal for complex surfaces and challenging areas.
Liquid waterproof membranes can last 10+ years, but lifespan depends on type, application, and exposure. Quality membranes paired with proper installation can even last 60 years! Be sure to choose the right one for your surface and consider reapplying if needed to maintain protection.
Start by thoroughly cleaning and drying the area to be treated. Depending on the product manufacturer’s recommendation, you might need to apply a primer for better adhesion. The liquid membrane can then be applied using a brush, roller, or sprayer, making sure to apply multiple thin coats for optimal effectiveness. Each coat requires a specific amount of drying time, as indicated in the product's instructions. Bear in mind that, based on the type of membrane and environmental exposure, it might be necessary to reapply it every 5 to 10 years.
