Hi Andy, you might not be able to demonstrate things right now, but you sure can educate us right now. You have the knowledge, let it out!

Did this exact project (consulting with Andy) for a Beneteau 361. Just as he said, sand, primer and paint all the smooth areas (non-nonskid) first. Then I taped off the smooth areas and hit the non-skid with 60 grit to take off the peaks. The 60 grit was aggressive but it went much quicker. I wasn't looking to get the surface completely smooth. Then I used flexible 2 part epoxy and squeegeed it over the sanded areas, filling in the remaining valleys. Next was the Alexseal primer. Note that you have to pull the tape after each layer, otherwise you're going to spend a lot of time removing tape with a razor. The rubber granule non-skid was poured over wet Alexseal top coat paint. Used a very clean vacuum to suck up the excess after allowing to dry. Then 2-3 coats of topcoat paint to seal. Some of the slip holders in my marina routinely do the Newport-Bermuda race. They all planned on doing the same process, given the soft surface with superior grip. Not going to lie, it was a week of very long days and frustrations. But, the end result was truly stunning.

There's always sand blasting to remove surface contamination. It's really messy and hard to do correctly, but nothing can beat it for providing a clean surface ready for painting.

@glenndennis6801 9 ай бұрын

Fiberglass should never be sand blasted. I know people do it, but it's really not acceptable. Walnut shell media is barely acceptable. Peeling with specialized planer is the recommended method.

Hi, my suggestion for a very secure solution would be ( if possible ) to sandblast the surface. This is very fast ,safe and cheaper at the end..

I think the "sprinkle on soft sand" (or rolling) and "Kiwi Grip" looks amatureish! Nothing looks as good as the molded in non-skid. Before filling with fairing compound and sanding smooth, (starting over with a flat surface) I'd test a small section of non skid and apply primer and paint. If it looks even marginally good, it will still look better that soft sand or Kiwi grip. Just my opinion :) Love your videos!

I’ve had success with top coating diamond pattern non skid as well as smooth gel coat by power washing several times, first with a degrease/wax, then with an aggregate (soda), then a couple times with fresh water. Be sure to do a final wipe . I roll and tipped with a 2 part epifane’s with 10% thinner….. 2 coats, no primmer, 6 years out, still looks fresh. Non skid still has grip…..

I saw someone on another form say to use a bristle disc (3M, Scotchbrite) with a gritty cleaner like comet. What do you think? I have a 42' Technomarine C42 Tiger from 1984 that needs the whole superstructure painted and I'm really trying to figure out what to do with the molded diamond nonskid over the massive deck...

Before you go for shoulder surgeries, please please try Perfotek Hydrolyzed Collagen Peptides. One scoop every day. My guess is you might feel a whole lot better in 2 to 3 weeks. If you keep it up, the study showed cartilage growth of up to 1/8 inch in 66% of the study patients. It has helped me and so many of my friends. There are scan photos in the study showing bone on bone going to new cartilage in the joints. I am 81 and have not been to a quack in over 20 years. Dad was all but crippled and had 3 hip replacements which only helped a little. I started taking Arthro 7 when my hips started to hurt when I was in my early 50s. That helped for a long time. In my early 70s my knees really started to complain. I found the study on collagen, started taking it and it worked wonders. Even a fall that really injured my shoulder, is now fine after three years. I just will not listen to anyone who profits if I am sick. I do my own research.

I work at a boat yard, and like Andy said, there's no way to guarantee that the diamond pattern non skid will ever be clean enough, especially with old, chalky gel coat. Yes, you could try to clean as best possible, but on my boats, I sand the diamond pattern flat and start with a nice flat, fresh surface and use sand.

@danielturco5809 9 ай бұрын

Just as an alternative, if the surface softens/ bubbles, would it be just as effective to soak the surface with the reducer and then pressure wash the surface? For the bite into the surface, would you consider soda blasting the surface, which also ensures all of the paint is removed. Additionally, is a chemical etch possible with the paints you discussed? Back in the day, we would use Skipsand to ensure the bonding of bottom paint.

@pointnemo72 9 ай бұрын

Was skipsand a chemical? Or a process?

@danielturco5809 9 ай бұрын

Skipsand was brushed on like a primer, leaving a translucent tint. It was wretched smelling, even outdoors. It probably shortened the lives of everyone who used it. LOL

@SV_Aroo 9 ай бұрын

Others have already suggested sandblasting. You could remove the paint with a stripper, especially if it's a one-part paint. Aluminum oxide and carbide abrasive powders are readily available, 80 grit and coarser, and could be applied with a hand wire brush to provide plenty of tooth. Pumice is friable and fine and is used for rubbing out finishes. Comet? Spray or a good brush could apply an even coat even on the peaks and valleys if a roller failed. I wouldn't want to build up a smooth surface with fairing compound on top of a deteriorated paint layer with just the peaks sanded down to gelcoat. That could fail dramatically.

I always sand off non skid and remold with gelcoat thickened with cabosil.... Bio blue works decent for wax removal on gelcoat for pre painting.

@kevinjamescerce 9 ай бұрын

I liked this video. I used the bio blue before on a new bottom paint. It worked pretty good but I wouldn’t say it saved much time. Maybe using a scotch bright with the bio blue would work on a nonskid surface?

Tape-Washi ultra-premium painter’s tape-lasts in the sun for a long time, holds up to rinsing off, (but not direct high pressure)even sticks to a wet surface. Costs about $8. So much better than the blue tape and as good as the $100 silver tape that’s no longer available.

Could you sand blast the Surface????

@todddunn945 9 ай бұрын

Well presented. Filling in the non skid pattern with paint is always an issue. Personally I don't like the idea of going over the non skid with a wire brush. There is no way you will be able to avoid leaving scratches in the gel coat. If you opted to go that way I think an aggressive scotchbrite type pad would be a better choice, but I still think it is a lousy idea.

@svlamancha9877 9 ай бұрын

Great video. I re-watched your earlier video and was wondering if you can use soft sand with gelcoat. Thanks 👍

@countryracer69 9 ай бұрын

Just curious about using a small sand blaster to clean and sand the area? The results with the paint filling and diminishing the nonskid would still be the same however

@TheBronDancing 3 ай бұрын

Dear Andy, thank you. May I ask please, if the non skid is the original gelcoat can you clean and then apply a new thin coat of gelcoat over the top. My deck non skid will not come clean - its either that or sea deck.

you'll run into the same issues as mentioned in the video coating with paint. Loss of texture and bonding would be an issue :-/

Practical Sailor Suggestion for next episode: It is pretty much impossible to get a professional to come to a dock slip to paint the topside. Every shop I contacted said I would have to bring my boat to their warehouse shop. Well, that is absolutely impossible due to my boat not being able to be trailered unless I spend a fortune to have it hauled, de-masted, transported, etc. Plus, there is no one in our area who provides such service. So, DIY is the only way to go. It os illegal to spray a boat while it is in the water. This is due to environmental issues as well as the practical issues associated with spraying in the vicinity of boats that are docked next to them. So, painting with a brush and roller is the only way to paint the topside. Almost all videos about using 2 part epoxy (and one part EZ Poxy) are for doing the hull. There are virtually no comprehensive videos about redoing the deck and cockpit. Yes, EZ Poxy is recommended for the deck and cockpit. But, the advice and tips usually stop there. I am referring to the need for advice and tips on how to prep and paint these areas. More specifically, how do you prep the the deck and cockpit in relation to dealing with curves, textured walkways, angles, hardware, and teak. For example, how do you sand a diamond textured surface since you can’t get into the valleys? Often, textured surfaces are a different shade or color than the smooth surfaces. When so, what gets painted first, the textured surfaces or the smooth? How do you deal with all the masking if the textured surfaces are a slightly different color than smooth ones. How do you prep gelcoat that has lots of spidering? How many coats? It would be a nightmare to detach hardware and teak. Will painting around them look ok? What about bugs landing on uncured epoxy? Due to the complexities involved in refinishing the top surfaces, it is easy to see why no one really wants to do it, especially when there aren’t detailed videos on it. Have I made a good case for a DIY video on re-finishing the topsides?

Sandblasting or pressure washing paint remover was not an option because the boat is in the water and I don’t want to make a mess. In addition, the weathered gel coat is softer than the paint. A Bosch 6” RO sander with a Dust Deputy and a shop vac does fine. Stripping the smooth areas are far more tedious.

Thanks!!! Has anyone field tested refresh / etch solutions on Cape dory’s original molded rubber/ non skid ~ that were deemed successful ? Seemingly futile … The aftermarket products seems a downgrade of paint and sand/ glandular materials not the cushioning assigned to the original non-skid not to mention the mayhem / removal efforts of the original Aftermarket paints include glandular materials but not the “ rubber “ which I deem superior

Your title said “Can you paint over molded gel coat”? You talked about painting over one and two part paints but what about over gelcoat? Did I miss something?
