Flexitec 2020 Primer is recommended for all porous, bituminous, cementitious, timber and PVC single ply substrates. NB - Failure to prime porous surfaces, such as concrete, brickwork, tissue-faced insulation or plywood may result in an under-cure of the Flexitec 2020 resin and potential system failure.
GRP surfaces, including ResTrims, do not require priming. Application Conditions Flexitec 2020 Primer should be applied in dry conditions between 5°C and 30°C ambient air temperature. Do not begin if conditions could fall outside of the temperature range and/or if rain appears likely.
Flexitec 2020 Primer is applied at a coverage rate of 3.5 to 5.3m2/kg depending on surface roughness. Rough or highly porous surfaces will significantly reduce the coverage rate. All coverage rates are indicative only and it is your responsibility to ascertain the exact coverage rates on site.
