Everbuild® Liquid Roof

Everbuild® Liquid Roof

A READY TO USE, ALL WEATHER ROOFING SYSTEM

Everbuild® Liquid Roof is a fast-curing, polyurethane based waterproofing liquid membrane for flat and pitched roofs. Everbuild® Liquid Roof has excellent adhesion to both porous and non-porous substrates and is suitable for use on new projects, extensions or to refurbish an existing, leaky roof. The product has a moisture activated curing system that allows the product to use atmospheric moisture to trigger the curing process, which means that no catalyst is needed and the product is fast curing.
With a 2 coat application to a variety of substrates this fast curing membrane cures in a range of weather conditions (see limitations) and is completely rain resistant in just 10 minutes.

  • Suitable for use with both new and old roofs.
  • Moisture curing technology –no catalyst required.
  • Fast curing – rain resistant after 10 minutes.
  • All weather product.
  • Ready to use – apply with brush or roller.
  • Forms a seamless membrane.
  • Can be reinforced.
  • Easily recoated, no stripping required.
  • Provides cost effective life-cycle extension of failing roofs.
  • Vapour permeable – allows substrate to breathe.
  • Elastic – retains flexibility even at low temperatures.
  • Compatible with common substrates: Cement, concrete, brick, stone, metals, wood, tiles etc.

Usage

  • Water-proofing of flat and pitched roof structures.
  • Treatment of new construction and refurbishment of existing structures.
  • Ideal for use on concrete, mortar, brick, stone, fibre cement, roof tiles, metals, wood and tiles. Can also be used on roofing felt, asphalt and bituminous coatings however full reinforcement must be used with these surfaces as they may soften after application. Reinforce using a suitable reinforcing fleece.
  • For waterproofing underneath tiles bonded with adhesives on balconies and terraces.

Application

Application Information

Ambient Air Temperature

Ambient temperature must be between +5 °C and +40 °C and maximum 85 % relative humidity.
Beware of condensation as it may affect adhesion and appearance.

Substrate Temperature

Substrate temperature must be between +5 °C and +60 °C. Moisture content of substrate must be ≤4 %.
Application steps

SUBSTRATE PREPARATION

Ensure substrate is in good condition e.g. cracks sealed, sound joints, tiles securely fastened etc. All timbers used in roof constructions must be suitable for exterior use. Adhere to good building practices in the selection of building materials and design of roof constructions.
Make sure any gaps are filled with an appropriate sealant before using Everbuild® Liquid Roof.

APPLICATION

Everbuild® Liquid Roof can be applied using a soft bristle brush or a solvent resistant roller. If product has settled or separated on opening, stir gently in order to achieve a uniform colour. Do not overmix as this will cause air entrainment. Generally priming is not required (see limitations); for porous or irregular surfaces apply an additional priming coat of 0.25-0.3 L/m². Ensure all surfaces are sound, clean and free from dust and loose friable material prior to application. Protect handrails etc. with tape and/or plastic wrapping prior to application.
Roof coatings – At least two coats of 1 mm depth are needed. Allow for the first coat to dry before applying the second coat (6 hours at +20 °C).

Ambient Conditions

*If time between coats is longer than 4 days, clean surface and apply reactivation primer before applying second coat.

N.B. # When using on wood; Everbuild® Liquid Roof should be applied in conjunction with a suitable fleece, e.g. Sikalastic® Fleece 120.

CLEANING OF TOOLS

Clean all tools and equipment with xylene immediately after use. Hardened/cured material can only be removed mechanically. Wash hands and skin with soapy water, or use Sika® Wonder Wipes.
