UV-resistant, High Elastic polyurethane waterproof membrane


CLI - PU Elasto Bond is a Two - component UV resistant, highly elastic, moisture curing polyurethane waterproof membrane.

know more


CLI - PU Elasto Bondis suitable for applications to most common building substrates including concrete, fibre cement, plasterboard, timber, and some metals. It is suitable for use as a waterproof membrane for wet areas as described in AS 4858:2004 “Wet Area Membranes”. It can be used as a Flexible membrane and coating for:
• Exposed roofs, Car park decks, terraces, gutters, flashing, walls
• Tanks, reservoirs and pipes
• Shower recesses
• Wet areas
• Balconies
• Retaining walls
• Planter boxes
• Slab floors


• UV resistant and non-yellowing
• Excellent mechanical resistance
• Can be made slip resistant
• Versatile - can be used for a flexible coating and as a waterproof membrane
• Good crack bridging ability
• Excellent thermal resistance
• Fact curing
• Good resistance to a wide range of chemicals and detergents
• Approved in accordance with AS 3740 - 2004 “Waterproofing of wet areas within residential buildings
• Approved in accordance with AS 4020 - 2002 “Approval for Use in Potable Water


Surfaces must be clean and free from all traces of loose materials, old coatings, curing mem branes, release agents, laitance, oil and greases etc. Substrate compressive strength should be at least 25 Mpa, cohesive bond strength at least 1.5 Mps.

Structurally unsound layers and surface contaminants must be mechanically removed by abrasive blast tracking or grinding. Substrates heavily impregnated with oil must be cleaned by torching or suitable solvent cleaning methods. To check that all traces of oil have been completely removed. Sprinkle a few drops of water over the surface. If all the water is quickly absorbed, the surface is sufficiently oil and grease free. If the water forms into globules that remain on the surface, further thorough treatment of the concrete is necessary.

CLI - PU Elasto Bond acts as a self-leveling coating and will not re-profile irregular substrates. For re-profiling defects on horizontal surfaces a suitable patching mortar is required. The patching mortar can be of epoxy or cementitious base depending on the scope, particular conditions and require ements of the work Contact the Carbolink India technical department for further information.


Prime the substrate with one coat of CLI ElastoBond diluted with CLI – XY Thinner.
