What is this deck made from?

[Tim Good]

The benefit being lack of maintenance which, as you have found out, is not a total lack.

True but 18 years with just a few minor cracks is not bad. Another Seastream made a year before mine has mostly been in the UK and has no cracks so no doubt the Med sun was to blame where by boat spent all its life until now. I recon a careful colour matched epoxy mix might be fine and may experiment on a small area.

Interesting... The patent seems to belong to the then MD, Luitgard Wolter. I'll see if I can get in touch with that person to get a copy of the installation specifications

Great find thanks! It notes "19. Method according to claim 10 comprising applying sand as an anti-slip material prior to final hardening of the layer forming the upper surface of the deck covering."

Is sand the normal anti slip agent used in epoxy non slim systems? Can anyone experimented with it and can give an indication of the sand type? I imagine it is quite critical in terms of grain size.

Chatting to a friend who is our local GRP expert told me to use polymer beads that have the same density of point so will not sink once the paint is applied.

Havent looked into this too much as I am not ready to replace the treadmaster I currently have and is coming off at the edges.

This is a useful read

GripTex by Awlgrip is a similar material.

Sand is sold for use in paint - e.g. https://www.boatpaint.co.uk/acatalog/International-Non-Slip-Additive.html, though I seem to recall seeing some type of beads (as mentioned) sold by one of the bigger boat paint companies.

I think it's carborundum that is used on what seems to be epoxy (but could be polyester) resin on the grippy 'caulking' strips in She-decking , probably in part for the dark colour.

Not epoxy unless you intend over painting it as it isn't that uv stable. I suppose you can get a stabilised version though.

Ok final bit of feedback which I have managed to get from the former Yard Manager of Seastream who dealt with this product:

"Over Deck consists of a base layer of black epoxy on which the planks are formed with then tape strips on either side, then a beige epoxy is applied on top and sand
sprinkled on before it goes off, when the tape is pulled off the black is revealed as the caulking, the loose sand is then removed and a clear sealer is put on top of the whole system. It's relatively easy to repair, not sure if the original company still going as they could supply you with the materials to repair if not you could buy the epoxy / pigment etc from a resin supplier and make up a kit yourself"

Very interesting. Looks like I was wrong about not forming the black strips with tape. Probably needs a keen eye and lots of patience to get it right. At least the cracking is largely cosmetic and the structure underneath will not be damaged.
