Surface Preparation 

The success of any waterproofing system is dependent on the thoroughness of the surface preparation.


New concrete decks should be a minimum of seven days old. The substrate must be clean, dry and structurally sound. It must be free from laitance, oils and all other surface contaminants.

Where the use of a non-structural screed or a lightweight concrete substrate is proposed, contact Technical Services. These materials often have low cohesive strength or retain water in open pores.

Use METASET®  ResiFilla Levelling & Repair compound for rapid repairs to damaged concrete.


On steel surfaces all rust, dirt and contamination should be removed by blast-cleaning to expose bright metal to achieve a surface cleanliness meeting ISO 8501-1:2007, Sa 2.5.

For compatibility with other construction materials or where additives, cement replacement or curing compounds have been used please consult the Technical Services Department.


ELIMINATOR®  is spray applied to give a minimum dry film thickness of 2mm, in either one or two colour-coded coats. The coverage rate will vary with surface texture.


The resin components of the ELIMINATOR®  system can be applied by airless spray or by hand, do not require heating, and include a BBA-approved Hand Grade membrane.


The substrate must be primed with an appropriate GCP primer prior to application of the ELIMINATOR® membrane. A choice of primers is available depending on the type of substrate and weather conditions. They are usually applied using spray, brush or roller. Please consult the appropriate datasheets.

Tack Coat/Bond Coat

A tack coat or bond coat must be applied to ELIMINATOR®  when it is being used as a waterproofing membrane on road bridges underneath asphalt or macadam surfacing. A range of tack coats and bond coats is available depending upon the pavement specification( ).


All tools and equipment should be cleaned with acetone before the material is allowed to cure.

Packaging & Storage

Primer/Tack/Bond Coats: refer to separate datasheets

ELIMINATOR®  Membrane: 48kg & 400kg kits

All components of the ELIMINATOR®  system should be stored in cool, dry, protected conditions, out of direct sunlight and in accordance with the relevant site Health & Safety regulations. Storage temperature must not exceed 25°C. Do not store near naked flames or foodstuffs.

Stored in unopened containers, under the correct conditions, the components have a minimum shelf life of twelve months. If your product is more than twelve months old contact Technical Service before use.
