Deck paint again

gtflash · 12 July 2021, 20:00

I would like to renounce my previous posts that commend kiwi grip. As beautiful as it is and as easy as it is to apply. It blisters on any area that has standing water, shows dirt and peels.

Now I’m looking for other reccomendations. Even outside the boat industry. My mates pickup has U-POL raptor paint and it seems a perfect finish for a deck. I have emailed UPOL and they state it is even safe underwater.

I could remove all paint and re gel but I know it’s going to be a bore. If anyone has any other reccomendations that last longer than 3 seasons I’d appreciate it. For now I will jet wash it off and enjoy the season tatty.

Just grind it back and use none slip flow coat its cheap, hard as nails & needs minimum prep just sand back with a 36g soft sanding disk or flap wheel and brush it on , hides all the sanding marks too. Cant understand why anyone would use anything else on a fibreglass boat deck

Because I have some epoxy repairs. So felt it safer to use paint.

I use International Deck Paint over the top of their one pack undercoat. I only applied one coat and it has stood up very well. The plan was to do a couple of coats and I'll get round to it at some point.

I clean it using a degreaser from Screwfix and a telescopic handled car cleaning brush and it comes up very clean.

It is a ply deck though.

You could look at something such a seadeck for a quality long lasting product.

For the record Ive used Kiwi grip on several vessels (my last three) and never had a blister but agree it can hold dirt and fish blood etc but has always cleaned up well with either a good scrubbing or pressure wash. For it to blister sounds like water has gotten under the paint which could of been down to surface preparation before applying it. Removing any dirt, grease, oil or silicone (even silicone spray) before applying is key.

I agree. However it is only the standing water areas that have failed. I have two small wells that collect deck water. They always peel. I have touched those areas up several times so the second and third application might not have been as reliable.

I have some pained on a fibreglass dive step that sits underwater and never blistered, could the surface you painted have moisture inside it possibly ? All the surfaces Ive painted have been fibreglass in the past.

By the way Im not trying to defend the product, its something I will certainly watch out for on any further projects. The fact we get very little rain and lower humidity in my part of the country might help, also I have no areas that pool water.
