abe.®proof liquid membrane

A single pack, solvent borne, rubberised, liquid applied waterproofing membrane that is highly elastic and durable, requiring low maintenance.


abe.®proof liquid membrane can be used to waterproof most building substrates typically:

  • Non-porous screeds, concrete, wood, polyurethane and bituminous surfaces
  • For the refurbishment of existing, new and old bitumen membranes without the removal thereof
  • Seamless, detail free singular membrane
  • Superior water resistance, stands up to water ponding
  • High elasticity and durable offering good tensile resistance
  • Excellent thermal stability
  • Excellent adhesion to most prepared substrates
  • Fast curing, second coat applied after 4 hours and full cure in 24 hours
  • Moisture insensitive, can be applied in cool, warm and humid conditions
  • No fabric reinforcement required for standard applications
  • UV stable, non-yellowing and standard reflective overcoating may be applied
  • Quick turn-around time in simplicity of application makes it economical
  • Contains a minimum of 10% recycled product
  • Low VOC levels, within EPA regulations
Typical Properties

Surface Preparation

All surfaces are to be clean, sound, free of all laitance, grease, all fungal growth and loose flaking particles. This could be achieved by wire brushing or suitable high pressure washing, finally rinsing with clean water.

New galvanised iron:

The surface has to be thoroughly cleaned using sugar soap or any other grease cutting detergent to remove oils followed by thorough rinsing or high pressure washing using clean water to reveal a clean, sound, water break free surface.

Old galvanised iron:

Remove all loose rust, dirt, salts of zinc corrosion and scale by means of wire brushing, sanding, chipping, or mechanical scouring — down to bright metal followed by thorough rinsing or high pressure washing using clean water to reveal a clean, sound, water break free surface.


A solvent wipe using MEK or oil free acetone to remove any natural wood oil prior to applicatio


Slow mixing or thorough stirring using a flat paddle just to re-homogenise the product before application.


Priming is a surface conditioner that offers optimum performance of the product.

  • Sound concrete and non-porous screeds – no priming required
  • Porous surfaces, asphalt, deficient bituminous surfaces and wood — prime with abe.®proof liquid membrane primer
  • Galvanised and metal surfaces – prime with abe.® 4-metal primer

When a primer is used allow the abe.®proof liquid membrane primer to dry for 45 minutes before applying the abe.®proof liquid membrane top coats.

The product may be applied by brush, short nap roller or airless spray equipment.

Two coats are required allowing 3 hours between coats, each coat is to be applied at a rate of 600 μm/m2 WFT (1.66 m2/L/coat).

Protection on Completion

All surfaces require suitable protection from dirt and contamination between coats and until the final coating has fully cured.


Approximate coverage:

1 L will cover 1.66 m2/coat providing a WFT of 600 μm per coat, 2 coats are required.

Model Specification

A highly elastic, durable, low maintenance liquid membrane for waterproofing.

The waterproofing will be abe.®proof liquid membrane, single pack, solvent borne, low VOC, liquid applied waterproofing membrane applied in two coats at a rate of 0.6 L/m2 per coat in accordance with the recommendations of a.b.e.® Construction Chemicals.


abe.®proof liquid membrane is supplied in 5 and 20 L containers.


Tools and mixing equipment should be cleaned immediately after use, and before the material has set with abe.®super brush cleaner, followed by washing with soap and water.

Handling & Storage

abe.®proof liquid membrane has a shelf life of 12 months if kept in a dry, cool store in the original, unopened packs. If stored at high temperatures and/or high humidity conditions, the shelf life may be reduced.

Health & Safety

Suitable protective clothing, gloves, eye protection and respiratory protective equipment should be worn.

Ensure adequate ventilation and do not smoke, use flame or naked lights during application.

If material is splashed into the eye, wash with plenty of clean water and seek medical attention.
