Waterguard Liquid Membrane: A versatile waterproofing solution for diverse applications

FAIRMATE has introduced an innovative solution in its Waterproofing range called WATERGUARD LIQUID MEMBRANE, which is suitable for a wide range of applications, including wet areas, foundations, basements, terraces, retaining walls, bridge abutments, planters, inverted roofs and remedial repairs to felt, asphalt, concrete, fibrous cement or other roof structures.

WATER GUARD LIQUID MEMBRANE is a ready-to-use, single-component, high-performance coating based on bitumen that dries to a tough, impermeable, waterproof membrane. It is ideally suited as a vapour/salt barrier for building facades behind granite, marble, stone cladding, and curtain wall elements.

Being a water-based and environment-friendly material, it enables good adhesion even when the surface is moist. It provides elasticity, ensuring a permanently flexible barrier over various temperatures. It is a cold-applied material that does not require heating or thinning. It has outstanding oxidation resistance, UV Light & embrittlement and provides a seamless insulation layer. Moreover, no special skilled person is required for its application.

Recommended uses:

· Useful as a protective coating on concrete and brick foundations, retaining walls, timber, metals, etc.

· Provides a sandwich membrane in new construction and surface treatment on existing slabs.

· Provides a key for plaster on difficult surfaces.

· For waterproofing and protection of concrete structure columns and beams.

· Used for the external insulation of foundations, underground constructions, basements, etc.

· Used for insulating water leakages in closed, damp environments such as bathrooms, kitchens, toilets, etc.

Application instructions

For proper application, it is crucial to prepare the surface adequately. Ensure that all substrates are in good condition free from defects such as protrusions, voids, honeycombs, and high spots. Any presence of curing agents, paint, or oil can hinder adhesion, so make sure the surface is clean and dry. Remove any moss and lichen and treat the area with a proprietary fungicidal wash to eliminate spores and prevent further growth. After treatment, thoroughly wash the area with clean water and allow it to dry. Create fillets for corners or sharp angles using a 4:1 sand and cement mortar mixture modified with a high-quality bonding agent known as FAIRCRETE SB (L).

Priming is necessary only for poor substrates. Address any cracks by applying a minimum 1.5mm coating of WATERGUARD LIQUID MEMBRANE, extending 75mm on either side of the crack. Allow this to cure overnight before proceeding with the general application.


The membrane should be applied directly by brush to obtain a continuous, unbroken film. Two coats are required, with the second coat applied at right angles after the first coat has healed.

WATER GUARD LIQUID MEMBRANE must be protected from mechanical damage during subsequent construction or backfilling works. Any damage may be repaired by spot application. If a water flood test is to be run, the membrane should be cured for at least 10 days.

 Whilst this membrane is resistant to frost, adhesion will be impaired if applied to frosted substrates. Application should be avoided if substrate temperatures are below 5ºC or rain is imminent.
