PrimeMat Fiberglass Mat for Boat Building – CSM Marine Guide

PrimeMat guide to fiberglass mat selection for boat building: which chopped strand mat (CSM) weights suit hull layups, decks and liners, how CSM bonds with woven roving in a hand lay-up schedule, resin compatibility for polyester, vinylester and epoxy systems, and mould preparation points that decide surface finish. Includes notes on marine repair work – blister repair, tabbing and stiffener bonding – and on the mat-to-resin ratio that governs laminate weight.
