Author Topic:   MOLD FOR NON-SKID SURFACE

NEVER SCARED posted 10-12-2001 01:33 PM ET (US)
Since gel-coat repair must be done on the non-skid surface, I came up with a method for making a pattern mold:
1 Choose a non-skid area that is least worn.
2 Clean and wax a 6 x 6 in area.
3 Pour enough West System Epoxy to cover area.
4 After the epoxy cures, pry it off the floor and there you have it!
Remember to wax the inside of the mold everytime you use it.

N.S.- what is your procedure for using the mold when repairing non-skid deck? I've got a '71 hull w/ BW blue inner... is that the same pattern as yours? How does it work?

PAID4,
My boat is an 87 Outraged 18', Im not sure if BW used the same non-skid pattern for the early boats. After you've made the mold, add a little gelcoat to the repair area and a little to the inside area of the mold that will sit over the repair spot. I use a tooth pick to fill in the tiny holes of the mold with gelcoat so air wont be trapped under. Im only fixing areas .25 diameters, larger areas could be tough!

Thanks for getting back NS- Do you press the gel coated mold onto the deck and leave it til it cures? or partially cures? do you weight the mold? It seems this technique may be feasible for larger areas. I believe I read a post describing a similar approach but, as I recall it was stated as a possibility and not something that was actually tried and proven and/or disproven. Anybody else out there have any experience with recreating original non-skid patterns over deck repairs?

I am atempting to recreate the non-skid in my '67 13 footer...I am told by a reputable dealer/friend that handles Rino (spray-on) that he can recreate the non-skid original blue interior floor. He claims to make it like new ! I recently read a thread on this and others seemed to agree...

I've been thinking about this topic, since I started to restore my 1972 13. How about tamping the wet epoxy with the end of a rough cut 2X4?

I recently wanted to fill in the holes where the orinal tanks were on my Montauk 170. I ordered Spectrum Patch Paste which is the correct color. Gibco sent a sample of the non skid for a M170 (GFBW 332). The cost for a 3 X 4 foot piece would be $100 while a one square foot piece would be $20. The representative at Mini-Craft of Florida stated that I would NOT be able to use the Patch Paste; it's necessary to use regular gel coat so that it can be thinned to run through a #2 zon cup. That way the gel coat runs ahead of the flex mold as you unroll whatever sized piece you're using. Evidently Patch Paste might cause air pockets (bubbles) under the mold. I'm going to try the epoxy method as described above before sinking the 401K into a few small holes. All this can be seen at www.minicraft.com then go to Gibco on the left side...Jim

Hey gang
You can avoid bubbles between the non skid pattern and the deck by pressing gelcoat inside the pattern, not the deck. When pressing mold onto deck, make sure pattern holes match up with deck pattern. Kinda like leggos.
Never scared

Neverscared, has your custom-molding technique worked well for you? Do you have any before and after photos? What is the largest area you have successfully repaired?
NEVER SCARED posted 02-17-2003 09:21 PM ET (US)
The places I fixed were old screw holes that I plugged. They were about 1/4" dia. Larger areas will be tricky. Biggest problem for me was the gelcoat curing in 50 sec. If you have many areas to fix, try a small one first. Practice makes perfect. Sorry no photos.
