Dubond’s Hydro Lastik extremely flexible two-part water-proofing for brush, trowel, roller or spray application. Suitable for hydraulic works in general, foundation walls against the ground, swimming pools, terraces and balconies. Component A is a waterbased special acrylic resin and component B, is a mortar based on a mixture of specialminerals, additives and well-graded aggregates.Once applied and cured, Hydro Lastik provides a non-toxic, flexible and waterproofcoating with very high adhesion on those common substrates in construction such as concrete, natural and artificial stone, traditional mortar plasters, bricks, concrete blocks, etc.

Shelf Life
- Provides a fully-flexible coating which ensures complete waterproofing even in the most severe conditions, as high negative water pressure
- Covers shrinkage and hairline cracks of the concrete
- Acts as an anti-fracture membrane between the substrate and other finishing coats if applied
- Excellent protection for concrete, being both a CO2 an chlorine (Cl2) barrier and thereby preventing carbonation and electrochemical corrosion
- Permeable to water vapour, allows the substrate to breathe
- Resistant to abrasion and UV rays
- Withstands atmospheric pollution, corrosive effects of salt water and de-icing salts and freeze/thaw cycles
- Resists hydrostatic negative pressure from ground water when used for underground interior applications
- Excellent adhesion and easy to use. Does not require bonding agents and can be applied on wet surfaces
- Non-toxic and chloride-free. Suitable for contact with potable water
- Longer lasting that other coatings, avoiding maintenance costs
- Environmentally friendly
- Withstands the root penetration, when properly reinforced with fibber glass mesh
- Waterproofing and protection of water retaining structures, such as drinking water tanks, reservoirs, water mains and swimming pools
- Waterproofing of below-grade structures like basements, retaining walls,foundations, tunnels, galleries subjected to both positive or negative high water pressure
- Internal and external waterproofing and protection of new and old buildings, facades against dampness, rain, pollution and aggressive environments
- Waterproofing and protection of concrete against carbonation, freeze-thaw cycles
- De-icing salts in highways and chlorine penetration in public works, irrigation channels, dams, retaining walls and water treatment plants, bridges, etc
- Tile fixing and waterproofing under tile and pavement in terraces, balconies, bathrooms, kitchens and other wet rooms in hotels, hospitals, offices and residential buildings, in indoor or outdoor use
- Waterproofing of window boxes, gardens and other surfaces subject to root penetration
- Hydro lastik is applied with a fibre type brush or by trowel when a smooth finish is required. For large areas Hydro Lastik can also be sprayed, being the recommended nozzle size 3-4 mm and spraying pressure between 3.5 and 5.0 bar. When sprayed, it is recommended to finish the fresh coat with a trowel to make sure that the whole surface is covered completely
- Apply two coats, using 1 – 1.5 kg/m² Hydro lastik per coat and allow a minimum of 16 hours and a maximum of 3 days between applications. Prior to application thoroughly wash down and saturate the surface, but do not leave free standing water. Thickness per layer should be 1 mm approximately, thereby being important to avoid very thin application or, on the opposite, a much thicker one. In those areas such as fissures, concrete joints and active cracks, once repaired and sealed
- Place the mesh on a first coat of Hydro lastik with at least 20 cm wide of strip, and then apply a second coat of Hydro Lastik
- Application conditions Optimum application temperature is between 10˚C to 25˚C. Do not apply below 5˚C or if lower temperatures are expected within the following 24 hours after application. Do not apply on frozen surfaces or if rain is expected 24 hours after application. Protect against quick drying by winds and direct sunlight with high temperatures, by fog spraying with water for two hours after application
- Curing time required to put the product into service or to immerse it in water will depend on temperature and relative humidity conditions on site. Conditions in the range of 20˚C and 50% R.H will require a minimum of 14 days to ensure that the product has cured enough to be in permanent contact with water. Applications made at lower temperatures or sites without ventilation will require longer curing periods. After curing, wash the surface of Hydro Lastik with water before putting into service in permanent contact with water
