The correct ratio of resin to glass fibre chop strand mat (450g csm) is 1.5 litres of resin per m2 of mat. For 600gsm mat your resin usage will be approximately 33% higher – the thicker the mat the more resin usage. 450gsm CSM for areas of occasional foot traffic. 600gsm CSM for areas of heavy foot traffic or load bearing(decking, promenade tiles, green roofs).
For ease of mixing, simply use the measurements on the PRO GRP Graduated Mixing Bucket. The buckets are graduated in kilos allowing easy calculation of the required hardener relative to the ambient temperature. Use in conjunction with Catalyst Dispenser for accurate measurement.
Catalyst must be added to all resin and topcoat in order for it to cure.
