Non-Skid Deck Gelcoat Kit - White Gelcoat with Non-Skid Additive

Worn non-skid is the most common thing wrong with an older deck, and it is a safety problem before it is a cosmetic one. Once the moulded pattern has been polished flat by twenty years of feet and buffing, waxing it makes it worse.

This restores the grip with the same material the deck is already made of.

What is in the kit

• 1 quart pure white gelcoat with wax and hardener
• 8 oz non-skid additive in fine, medium or coarse
• 2 oz MEKP hardener
• Three 3" chip brushes, 2 plastic spreaders, 4 graduated cups, stir sticks, gloves
• Wet/dry sandpaper in 6 grits and an instruction card

Picking a grit

• Fine for cockpit soles and anywhere people go barefoot or kneel. Grippy without being unpleasant.
• Medium is the general answer for side decks and foredecks. Start here if you are unsure.
• Coarse for bow pulpits, swim platforms and working boats, where wet feet and a real chance of going over the side beat comfort.

Why waxed gelcoat, and why that matters

Polyester will not cure tack-free in open air. Gelcoat sold for a mold face or an intermediate layer is deliberately made without wax so the next layer bonds to it. A deck is the opposite case. Nothing goes over it, so it needs the wax that floats to the surface, seals out the air and lets it cure hard enough to walk on and sand. That is why this kit ships the waxed quart and our tooling kits ship the unwaxed one.

Mask it properly. The line between non-skid and smooth gelcoat is what makes the job look factory or look homemade. Tape the border, pull the tape while the gelcoat is still green, and do not try to cut it in freehand.
