International Gelshield 200 is a quick‑drying epoxy primer for GRP hulls that protects against osmosis and leaves a hard, matt protective coat.

• Size: 750 ml (26 fl oz)
• Quick‑drying epoxy primer for GRP/FRP
• Protects against osmosis in five coats — 250 µm (0.25 mm) DFT
• Usable down to 5°C; fast drying allows multiple coats in one day
• Colours: Grey and Green; two‑colour system improves coverage and overcoating contrast. Use alternating colours starting and ending with grey. Bilges: Apply 2 coats only if there is gelcoat on the inside of the hull; if not, do not apply in bilges.
• Suitable for above and below the waterline; finish: matt
• Mixing: measured base + hardener; stir and leave 10 minutes to disperse bubbles

Apply over clean, sanded GRP (180 grit). Remove old antifouling with Interstrip where needed. Apply with brush or a 5-inch foam radiator roller for even coverage; use thinners code YTA061 if required.
