Installation

Temperature Requirements

ELIMINATOR membrane can be applied at temperatures of -10°C to +50ºC
Asphalt overlay up to 250ºC
Maximum application temperature +50ºC

Surface Preparation

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

Primer Application

All substrates 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. Primers are usually applied by spray brush or roller. Please consult the appropriate product datasheets.

Concrete substrates

New concrete decks should be a minimum of seven days old. A minimum concrete compressive strength of 3000 psi (20 N/mm2) is required prior to application ELIMINATOR Membrane. Where compression testing is not available, a tensile bond test with a minimum bond value of the membrane to the concrete of 0.7Mpa is required prior to membrane application. 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 GCP Technical Services. These materials often have low cohesive strength or retain water in open pores. For rapid repairs to damaged concrete use METASET ResiFilla Levelling & Repair compound.

Steel Substrates

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

Other Substrates

For compatibility with other construction materials or where additives, cement replacement or curing compounds have been used please consult our GCP Customer Services Department. ELIMINATOR Membrane Application: (Please contact your local GCP representative for complete and detailed application instructions). ELIMINATOR Membrane is typically spray applied. The membrane is applied when the primer has cured, typically within 20 minutes. ELIMINATOR membrane is spray applied to give a minimum dry film thickness of 2mm. It can be applied in either one coat or 2 colour-coded coats depending on the application requirements and local standards. Wet film thickness of 1.2mm wet equals 1mm dry, 2.4mm wet equals 2mm dry. The coverage rate will vary with surface texture.

Tack Coat/Bond Coat

A tack coat or bond coat must be applied to ELIMINATOR Membrane 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 are available depending upon the pavement specification. Contact your local GCP representative for more detailed information.

For technical assistance with detailing and problem solving, please contact your local GCP representative.

Cleaning

All tools and equipment should be cleaned with acetone before the material is allowed to cure. Review the supplier’s Safety Data Sheet (SDS) prior to use and follow all precautions.
