Bedding Compounds

[Vitalba]

I`m looking for a Bedding material to seal semi-permanent items to the fiberglassed ply deck of my East Anglian(items such as stanchions, jambing cleats, autohelm pivot, windlass, fairleads and grabrail, ventilator etc. on the coachroof). Some of these are mounted directly others on a wood or metal backing plate.
Previous owners had used Sikaflex type materials which bonded so well they took the sheathing of the deck when they were removed.
What is available in the general market - it seems to me that the building industry have very similar problems / environment to contend with and solve them at a fraction of the cost of any thing marked "Marine".
Forum comments please on expirence good and bad. What about low modulus silicon ?

I was recommended to use Marineflex Bedding Compound which is available here or direct from the manufacturer on ebay. It's a non-setting polyurethane and seems to work well.

I Use Frame Sealent From B&Q

The best non setting sealant is Evomastic, it is only available from jewsons but is worth using as it is excellent & cheap. Silicon should not be used anywhere near wooden boats as it will cause problems with painting & varnishing and it leaks!

Since receiving this advice I have been using Jewson`s Evo-stic Frame Mastic for semi permanent bedding which I find easy to work and seems a very satisfactory solution to the problem - although time will tell. I contacted Bostic the manufacture to find a source for Grey to suit my decks and was told they are discontinuing that colour. Some Jewson stores do have stocks and I believe a system for internal transfer if your local store has no stock. Their Part No. is LESFS2GR if you need to stockup. VITALBA
