Removing Old & Poorly Applied Deck Paint

So one of the brilliant PO's of my boat decided the original sand colored non-skid was too dark and caused the boat to get too warm in the summer. This genius painted over the non-skid with white paint. This must have been long ago as you can now see in the image about 50% of this coating has peeled away. Ideally, I will be able to use a pressure washer to remove the rest but if that doesn't work then I suppose a much more difficult task awaits. Before I start considering sanding it down and starting over does anyone have suggestions? Any short-cuts here?

Re: Removing Old & Poorly Applied Deck Paint

Stainless wire brush or wire brush wheel, if it's coming off that much maybe you can be sucessfull. Also, maybe a heat gun... carefully! Is it latex? arghhh Pressure washer may well get most of it.

Re: Removing Old & Poorly Applied Deck Paint

Well, the original non-skid is in great condition so I don't really want to damage it. My fingers are crossed for the pressure washer. Then I will look at using a very stiff bristle brush. I think if I have to go to wire brushes then we are talking about essentially taking off all the non-skid and re-painting with Kiwi…Doable but a whole lot of work.

Re: Removing Old & Poorly Applied Deck Paint

One option is to paint it!
If you don't know what kind of paint the white is, you put on a tie-coat, a paint that is compatible with what's is underneath and the poly that should go on top. If that will leave unsightly marks, then you have no choice but sanding/pressure washing/removing the white stuff and then repainting it.
Either way you may have to sand the deck... Its not a big deal, I had to do it and before I did that I had to open and fill all the gel coat cracks it had...
Best of luck

The right wire brush shouldnt destroy it. There are many options, take a look at Welders brushes for TIG welding etc, finer bristles. You could also test some of the more orgainic types of paint remover for what doesnt come off with pressure washing. Brush on, loosen up with stiff brush and wipe off using a multitude of paper towels....
I wouldnt go over maybe 1500-1800 psi with the pressure wash, depending on tip type.

Re: Removing Old & Poorly Applied Deck Paint

Wire brush is a good suggestion, you might try acetone/paint remover too.

Re: Removing Old & Poorly Applied Deck Paint

That paint does look loose enough that a pressure washer might work on its own but there are grit blasting attachments that can be used with pressure washers. If they'll push bead that might be kinder to the substrate than grit but I'm guessing - haven't done wet blasting myself, just dry. Not sure it's been tried for this, maybe someone knows?
If your non-skid is resilient/rubbery like Treadmaster I'd guess it might work very well but obviously try a small area first or check with a specialist.
I've just tried a wire brush on a scrap piece of well-weathered Treadmaster. Cut it to bits as I thought it might. You could try using the bristles of a new wire brush to tap - or beat - the surface rather than to brush it.
Normal paint stripper might be perfectly OK, or it might eat the non-skid instantly or a year from now.
Any chemists here?

S/V SeaSprite

There used to be a paint stripping process that started with a slow acting stripper painted onto the surface and then a fabric laid over that and left for a period of time. The fabric was removed taking most of the paint with it. Usually required repeat application to get the stuborn stuff but didn't damage the underlying surface.
I can't remember the name but I have used on a carved front door and found it quite effective.

Re: Removing Old & Poorly Applied Deck Paint

There are pressure washer attachments that basically turn the unit into a media blaster. You can use whatever substrate you prefer and that ranges from sawdust for polishing to coarse grit sand for blasting scaly ferrous metals.

I would think that the fastest easiest method would be to blast with a gentle media like soda with a pressure washer.

Can I use ARMEX® with my pressure washer?Yes. There are media injection devices available to introduce ARMEX® into the water stream of your pressure washer These attachments are available through the authorized ARMEX® distributor network.What is ARMEX®?ARMEX® is a baking soda based (sodium bicarbonate, NaHCO3) media manufactured by the makers of ARM & HAMMER® Products. There are over a dozen formulations designed to meet specific surface preparation requirements.ARMEX® - Baking Soda Abrasives: News and Information - FAQs

For the stubborn areas try this ---Nyalox, the original abrasive nylon brushes have been redesigned to improve performance over a broader range of uses. NYALOX is the only nylon brush line available in three grits and bristle diameters.
