Hi,

I have several areas topside I would like to repair. Most of them are only 1-2mm deep so will likely only need some Marine-Tex (open to suggestions) but I don't want a smooth spot in the middle of the nonskid. YouTube University has several examples of a "mold" that mirrors the pattern and you apply that mold over your repair and let it set. This produces a convincing factory outcome; however, I'm not seeing which molds (patterns apparently have specific numbers to ID) apply to a 1986 Catalina 25 (for example).

Thanks,

Carl

Carl, If the areas are not too big You can cut the pattern into the Marine Tex with a dremmel.Use a cutting wheel on the side to lightly cut the grooves/pattern.

Here's a link to an online discussion of different ways that you can make your own mold. https://www.catalina36.org/forum/technical-discussion/reverse-mold-non-skid-deck-pattern

I filled small areas, let start to set and drug a flat toothpick through it. I have the same plan as Scott suggests for couple of slightly larger areas. For a mold, thoroughly wax an area of good non-skid and cover it with a quarter inch or more of silicone calk. Peel it off when cured for a good mold.

Hi All,

Fast and informative as usual. Hadn't thought about tooling such a small area, good idea. I did see the mold creation online and a couple references to PVA? PolyVinyl Alcohol for an easy treatment/removal on surroundings. Anyone use it?

One other inexpensive possible option is to use a rough paint roller & roller cover, such as is used to apply Kiwigrip, when you put the Marine-Tex down so it creates a non skid surface in at least some sort of pattern.

Hi Bigelowp, I can appreciate inexpensive, for sure, although in honor of this boat's preservation, I'm going to go for broke on matching.

You could create a mold using plaster of paris provided you can get all the air bubbles out. If you have a good section of nonskid somewhere on the top sides, plaster of Paris can be used to create a square or rectangular area of mold about the same size and shape as the portion you want to replace, then if you put down some Marine Tex, you can spray wax into the mold and stamp the pattern onto a corresponding new Marine Tex surface before it kicks.
