I know that some of you have used masonry paint, eg Sandtex, on your decks. I'm thinking of doing the same on my grp deck when I have stripped the old paint off.

Question: Did you use a primer/undercoat on the bare deck?
 
I would not use masonry paint ever, I use international & mix to the colour i want. the only down side is it doesnt hold dirt :disgust:like masonry paint but is a tad more expensive, it costs me £22 for a 37 footer with wide side decks
 
Agree with sailorman. For the small difference in price - a few £s on a boat your size, why not use the proper stuff? A 750ml tin of Interdeck at around £25 will do your whole boat with some left over for touching up. Came out the best in the PBO trials.
 
All i can say i havent painted decks for many decades , however more decades ago than i care to remember i worked in an outdoor centre, i was initialy bemused to be asked to paint wayfarer floorboards with sandtex , however it stood test of time with very heavy use .

My boat had Sandtex fine texture masonry paint when purchased and have maintained the same ever since for 18 years. I do not know if the previous owner applied primer but over the years where i have done small repairs or moved fittings i have just abraded the bare grp and applied the Sandtex and it has never been a problem. It does get grubby after 2 or 3 years so i just remove the grit surface with a tungsten scraper and course sand then hose off and when dry paint on a single thin coat. It is water based and dries fast so you can walk on it within half an hour. It is very nonslip.

I am planning on using International interdeck on the deck, Do you think I can apply this on top of Toplac ?. I want to have a smooth finish on the edges of the deck and then apply nonslip in masked of areas. In terms of primer I was going to give the deck a coat of pre kote.

I never did. It is what I have been using for over twenty years. I recoat every five years or so. My boat is permanently afloat except for a three-week lift out every two or three years.
 
Slightly different question, if painting masked off areas of moulded in non-slip would it be better to use something like Interdeck, or use Kiwi Grip, which has its own texture (will the peaks conflict!)
 
I painted with Sandtex two years ago and it looked (and still does look) far better than the old 70s turquoise paint which had worn through in places. Obviously it can only be cleaned with a brush not a cloth but being able to just top up the paint quickly where rust stain or oil stain appeared is great. Took a very long time to prepare, mask off and 3 coats of paint but I'm happy.
 
I've used sandtex for years and didn't bother with a tie coat. It seems to stick alright although it is difficult to get a feather edge to touch up patches. It's nine slip properties are excellent.

I'm currently painting my non-slip areas with Sandtex Smooth Masonry paint. Haven't yet tested how non-slip the result is but it looks good and the the texture is apparent through the paint.
 
I painted my day boat's ply floorboards with Primocon and then Danboline all over (especially edges) and then masked the edges with approx. half inch tape and applied a coat of Interdeck on the upper surfaces. When I refinished them I just added another coat of Danboline to the top and found that the nonslip properties still worked.
 
I cleaned and quickly sanded my decks and then coated on dulux smooth masonry (weathershield?) paint. That was 4 years ago and the non slip is still very good. Big problem though is keeping it clean and it now needs repainting as it looks grubby and doesn't clean up well. As others have said , easy to put on and dries in an hour or so for walking on.

Presumably on a ferrp-cement boat, otherwise why would you consider doing such a thing?

Cost? Why should I pay more for a 'marine' non-slip - containing fine sand - when I can use masonry paint - containing similar fine sand - mixed to the precise colour that I want... at a fraction of the price?
 
Which deck paint has the best anti-algae properties?

I use Interdeck but algae soon appears, at least on the shaded areas and is a pain to clean off. I used an 'eco' boat wash a few weeks ago and the algae love it - they were back with a vengeance. In fact, I've never seen it so bad in such as short time.

(I'm in a loch with many fish farms in it so dare not use any of the anti algea patio cleaners (which have dire warnings of aquatic toxicity) for fear of a visit from SEPA!)

I wonder if there is an anti algae additive I can mix with the Interdeck next spring...
 
Found it VERY hard to keep clean.. Looked amazing for about 2 weeks then super grubby. Wouldn't do it again.
 
I used it and it worked fine for the 6 years I had the boat. But she did have concrete decks. I can't see why it wouldnt work on grp
