Plastic Padding epoxy products

[Kelpie]

My local swindlery only sells Plastic Padding 'glassfibre resin' which seems intended for use with cars etc (judging by the picture on the tin!). I need a wee bit of resin for bedding in screws, sealing around holes etc in a plywood deck. Will this stuff be alright? It seems quite cheap.

Secondly, they also do a 'gel coat filler', presumably this is the stuff I need to repair shallow scratches and scrapes on my hull?

Ta!

Hi I would think both this products as described would be fine. If you are doing some work and refurbing I would thorughly recommend the West Epoxy course. They are based near Southamptom, i am not sure hwhere you are but for around £100.00 they did a day on use of resin, epoxy fillers and all sorts. great fun and lots of practical experieince plus discount on products at the end of day- Good luck

G'day Rob,

Standard resins will not stick long term to any timber, this is why boat builders now use foam ribs to provide the profile but put a lot more glass on to compensate for the missing timber. More expensive to build but will last.

You need an epoxy mixed with 'Micro-fibres' to seal the ply. We drill out the hole 10mm oversize and after curing drill a new hole the size of the screw shank.

This means the timber is covered by a 5mm protective layer of epoxy.

Hope this helps.

Old saltz got it right

Polyester resin will stick to timber. (and let go in the future)

Epoxy will bond to it.......... (as it soaks into the wood)

I know I know thats not quite correct but it's close for a layman.

Thanks for the replies. Since I live on an island I am restricted in where I can buy things, and it seems that you cannot get epoxy sent by post.
Here's the stuff I can get locally:

By the way a mate of mine tried to use the PP 'marine filler' to repair scratches in his gelcoat and it all fell out! I think it must only be suitable for smaller, deeper, applications.

I have used PP Marine Filler to fix quite a big (50p) ding in my topsides, two years ago, it's been fine. No sign of cracking at all, and easy to use.
