Quick Tips:
Dry cut CSM before mixing up your resin to avoid sticky gloves, wasted time and a messy lay-up
Wet out one layer at a time and apply next layer while wet. For thicker laminates, build in stages (typically 2-4 layers at a time) to avoid excess heat when the resin cures
Choose the right weight of CSM for each part of your build:
100gsm – acts like a surface tissue
225gsm – gives controlled layering and helps reduce the risk of voids and bridging
300gsm – shapes well around curves and detail
450gsm – balances build up speed and ease of shaping
–
A few words on safety:
Glass fibres will irritate your skin and lungs. Wear gloves, long sleeves and mask when handling and sanding
