Deck Paint Renewal

[eyupdougdown]

When it eventually stops raining for a while, my deck is to be painted using durable masonry paint as advised by one avid ybw forum regular.

The deck already has a nice textured surface. Trouble is see, I'm wondering if the deck needs sanding off first as I am worried that if I don't, the new paint will simply 'fill the gaps' leaving a shiny surface?

Also sanding a surface with sand on it will take some sanding. y'get me?

This is a ridiculous question

since it will never stop raining

No such thing as ridiculous

There are no such such 'things' as a ridiculous questions - only stupid answers - so the Yard Gods tell me. Maybe I should build a shed?

In 4,700,000,000 years, Earth will have had been absorbed into our dying Sun - I feel there will be no more rain then.

Still before then, I would like to get the deck sorted.

Remove the deck from under the paint, then paint the underside of the existing paint allowing excess to fill the cracks. Smooth the outer surface with a spatula and replace deck while paint is still wet. This procedure can be carried out in most tempests but not monsoons.

Deck paint preparation

Although I have been removing rather more than just the deck paint over the last few years, I would recommend the same technique applied with less vigour, especially if you're looking at many years of accumulated deck paint. A 2-handed scraper (e.g. the Sandvik one from B&Q) should be run over it to remove any loose material. It can also be used to level the painted surface. It doesn't need to have stopped raining to do this, although if it has it will make the job more pleasant and reduce the time needed to dry off in the pub at lunchtime /forums/images/graemlins/smile.gif Too much vigour will remove more than the paint, I've been removing the gelcoat with a fair amount of ease, so go easy till you get the hang of it.

If Sandtex is like ordinary deck paint, it will stick to anything and doesn't readily flow into the gaps leaving bald spots, which is what, I presume , you are worried about.

Re: Deck paint preparation

Is it worth it,I would use the correct paint, last time some years ago I used TEAMAC deck paint, you should be able to get it from a painter and decorators supplier be a lot cheaper than chandlers. If the old paint is sound wash well with white spirit and roller it on, it contains sand in the paint.

Yes second this view. Plus if you sit out on it reinforce the bottom in your wet weather pants - mine wore through in a year!

Re: Deck paint preparation

There have been a couple of recent threads on the subject which is what I presume the original poster is referring to. The main drawback with sandtex et. al. is, apparently, that sand is sharper than the proprietary deck paint fillers and rips the hell out of your oilskins' knees. Otherwise it seems to be a case of "paint is paint" when it comes to durability. Personally, I use Blakes and a 750ml tin at a tenner or so does the lot. Not worth faffing about saving a few quid, IMHO, but if you've more area and less cash, it may be.
Once the surface is sound, as you say you clean (hoover and then wash), degrease (white spirit, acetone etc.) and then paint. Definitely not too thick.

One thing I found recently that is obvious with hindsight: You can mask areas against deck paint but not vice versa: the sandy bits let any other paint leak under the tape so if you are painting some non-textured areas surrounding the textured ones then do them first, or else don't rely on masking tape but paint a clean edge with a small brush.

Re: Deck paint preparation

International make a sand substitute which can be added to any paint. I certainly agree that sand on deck paint can be too rough especially if you sail barefoted or in shorts. the answer is of course to add more plain gloss over the sand to make it smoother. olewill
