Preparation
All surfaces should be free from all contamination such as de-icing salts, grease or oil, any loose or friable particles, moss or algae growth, dirt and frost. New concrete substrates must be a minimum of 14 days old prior to application.
Grease and oil should be removed using our Polycote Degrease IT.
CONCRETE: Concrete surfaces must be prepared using mechanical preparation; this can be done with a vacuum assisted shotblaster, floor grinder or equivalent method. Please note that water jetting will not key the surface suitably. All repairs should be made prior to application using one of our concrete repair products. We advise that you then prime the surface with one of our Polycote Primers, however this is not essential.
ASPHALT: For applications onto asphalt less than 28 days old, a test area should be carried out; this should cover all variations in the asphalt substrate. A circular area of about 100mm in diameter and about 5mm thick should be laid. Once this has cured, its adhesion should be tested with a hammer and bolster; if the product comes up, the asphalt will have to be left until it is 28 days old. The asphalt can be dried using a hot compressed air lance. The surface will not need priming.
STEEL: The steel should be exposed back to a bright metal – all rust, dirt, oil, grease and contamination should be removed. The steel should be primed, please contact one of the Polycote technical advisers for the correct primer.
Mixing
Having fully prepared the substrate, stir the resin part thoroughly. Settlement will have occurred during storage and transportation and you should continue mixing until the product has fully homogenised.
Add the aggregate and mix until it is totally stirred in.
The next step is to add the hardener – please note that adding the hardener starts the chemical reaction. The application of Slip Grip is very fast and everything must be ready to go before you start. The hardener should now be added and mixed until it has dispersed; this should not take more than 1 minute. For best results use a heavy duty slow speed drill with a mixing paddle. Ensure thorough mixing as an unmixed product will result in a poor or non-cure situation.
Application
The product should be laid at about 4mm using a serrated squeegee followed by a roller. The roller application should be perpendicular to the squeegee application (crossrolled). A medium pile roller should be used which can be supplied by Polycote UK. Once applied allow to fully cure before trafficking.
Application Temperature
Normal application temperature range is between 0˚C and 30˚C. For applications outside this range please contact Polycote Technical Helpline for further advice.
