new flat roof

LAVA 20 can be easily used to waterproof new roof and balcony structures easily by:

1. Prime the roof with Owl Prime.

2. Preparing the joints with Owl PU mastic.

3. Cover the area with the first coat of Owl Lava 20.

4. Apply the second coat of Owl Lava 20. Job complete.

LAVA 20 is a unique single component polyurethane liquid membrane.

Due to its unique formulation, it cures rapidly to form a completely defect free membrane with excellent mechanical and elastomeric properties. This product is ideal for use during the winter months or in climates with relatively low or high humidity. Furthermore, the fact that the minimum consumption can now be achieved in only one coat, reduces labor cost and eliminates previous drawbacks.

Application: can be applied by brush, roller or squeegee

Apply minimum consumption of  ±1.5 kg/m2.

Recommended for Waterproofing and protection of:

Roofs, Balconies and walk ways. Can be used directly on OSB Board,  Ply Wood, Gypsum and cement boards,
polyurethane insulation foams, verandas and balconies and other new and existing substrates.

roofs,
light roofing made of metal or fibrous cement, asphalt membranes,
EPDM membranes.

 

Features and Benifits:

Fast curing! Skin formation time of 2 hours. Bubble and defect free membrane.
No thinning is required but SOLVENT may be used.

  • Excellent weather and UV resistance. The light colour reflects much of the solar energy and so reduces the internal temperature of buildings considerably.

  • Excellent thermal resistance, the product never turns soft. Recommended service temperature 80 oC, max shock temperature 200 oC.

  • Resistance in the cold: The film remains elastic even down to -40 oC.

  • Excellent mechanical properties, high tensile and tear strength, high abrasion resistance.

  • Good chemical resistance.

  • Moisture vapor transmission: The film breathes so there is no accumulation of humidity under the coat.

  • Special primers available for almost every substrate.

    Application Prerequisties:

  • Can be successfully applied on:

    Concrete, Fibrous cement, Mosaic, Cement Roof Tiles, old (but well adhered) Acrylic and Asphalt coats, Wood (OSB / Ply Board). For information about other substrates, please contact our tech department.

Priming:

 Low Viscosity, polyurethane based primer / concrete sealer, for both porous & non-porous substrates, and both dry & wet concrete.

LAVA Prime 20 is a one component, low viscosity, polyurethane based primer suitable for many different substrates.

It is characterised by its very low viscosity and balanced curing speed which result in excellent wetting, impregnation and paint-over time on different substrates, whether of high, low or no porosity (e.g. glass and metals). Additionally, it can be effectively used on both dry and wet concrete, even green concrete, not only as primer but also as a low-cost sealing solution, increasing, thus, the durability of the substrate.

The cured film displays outstanding mechanical properties: Its elongation is >300%, and its tensile strength surpasses 30 N/mm2.

Benifits and Features

One component.
Of low viscosity.
Can be applied to damp concrete.
Adheres strongly, even on glassy, non-porous

substrates.
Excellent wetting, impregnation and paint-over time. Elastic.
Many pigment pastes available.
A low-cost solution for concrete sealing &
protection.

Apply with brush or roller. Once cured, the main membrane (e.g LAVA 20 System) can be applied.

Coating Application:

Apply the material with roller or brush in one or two, coats. Do not exceed 48 hours between coats. If more time passes (for example more than 4 days) or if you are unsure of the interlayer adhesion, please contact our technical department.

Coverage:

Coverage on substrates can vary; average 3 kg per m2. Apply 1.5 kg per coat; two coats recommended.

Precautions:

Contains volatile flammable solvents. Apply in well-ventilated, no smoking areas, away from naked flames. In closed spaces use ventilators and carbon active masks. Keep in mind that solvents are heavier than air so they creep on the floor. The MSDS (Material Safety Data Sheet) is available on request.
