Seat Sealant

[twilliams_34]

Hi
I have had to remove the rear seat in the cockpit to get it repaired. Having spent ages looking for screws or any fixings that held it on I discovered it was held on with a some type of sealant!

The repair is now complete and I need to fix it back on. Does anyone know what type of sealant I need?

Thanks
Tony

Usually a cheap silicone sealant applied in blobs will suffice. Degrease first, apply blobs that will spread out with a bit of pressure and retain in position with a little pressure for a day or so. Acetone is good for degreasing a grp area but NOT recomended for vinyl. Meths is better for degreasing vinyl.

Cant tell without seeing it. If it is twangy, it'll be ordinary silicone sealant. If it isn't as twangy and is more stiff-rubbery, it is likely sikaflex 291 which is a polyurethane sealant/adhesive used in general purpose boat fixing/building. It could be sikaflex 292 but that's unlikely - 292 is a very strong polyurethane sealant/adhesive and dries quite stiff - it's the stuff used to seal/glue things like cleats and chainplates to GRP (together with bolts)

Ordinary silicone might be ok but i suspect 291 will be better, for reassembly. Dont use too much though or yu'll never be able to remove the item

Thanks for the replies, yes it is more of rubber consistency so will have a look at the 291.
When you say do not use too much would 1" blops (technical term ) be about right?

Hi Tony

Sealine use just the basic cheap white silicone sealer for these jobs.

if you are going to use silcone its better to use DOW CORNING as it doesn't go hard or turn into powder, Regards
