Has anyone used this?

Looking to try and strip back anti-slip paint on fibreglass and gelcoat.

If this is good, anyone got a good supplier?

I've used this previously on a topcoat and I didn't find it great.

Seems to have mixed reviews - I'm not sure what the paint in place is, so just a matter of trying some various strippers I think

what do you mean by anti slip paint? somthing like an international paint with griptex in it? Good sanding may do it start off with a rough grit and work down to finer grit

There was a base coat applied, followed by a spraypaint job with non slip particles in it.

Tried an RO sander, but the paper was shredded quite quickly and it took a lot to get it back to the underlying gelcoat / glass.

Tried with a heat gun but very slow process, and there are a lot of hard to reach areas.

It looks like the original owner had a mould problem and just painted over it, that is why I want to strip it back, treat it and then repaint

try a belt sander on it and perseverence, its only paint by the sounds of it but as most jobs with boats they are never quick and easy

I would stay with the heat gun and a good sharp scraper, do a test run on somewhere out of sight to see how hot you can get it without damaging the gelcoat you should be able to get close to the paint bubbling and then quickly scrape it off.

We've done this, very slow going and teh gelcoat has been damaged in places.
To get the underlying coat (beneath the non stick) is very tricky, the heat gun has little effect before the gelcoat starts to bubble.

Beltsander is too rough I think.

These also work well and you can get them in different grades in B&Q you can also get them for an angle grinder if it very bad but you would want to be repainting and not trying to get a gelcoat finish.\

I got tried these and they worked well.

However, this lead to another problem....

I think I'm just going to crack on.

As it's inside the boat it wont be osmosis as we know it like blisters in the gelcoat as there is no gelcoat on the inside, it looks like something called "the pox" still osmosis in a way but where the water is trapped between the sealant paint an the fibreglass, you should be fine sanding it down then leave it to dry out and repaint.

CHeers, and for the bits where the paint seems to have been rolled on over fibreglass? Bit worried to go after that with the flapper wheel.

fergal.b

Just keep it moving and it should be ok the fibreglass will be a bit tougher than the paint and if you do cut in it can easily be filled, while your at it you could mark out a little patch somewhere out of the way and sand it down to the fibreglass strands and test it with a moisture meter to see if it is wet.
