Repairing Avon inflatable floor advice needed

[davidfox]

This is a rephrase of a previous post, can anyone help with advice?

The top and bottom 'skin' of the floor has sort of delaminated because of the heat forming large blisters from the escaping air any ideas on repair solution?

If it's delaminating I would think your only option is to cut out and patch, depends on the size of the area and location. If a large area it may not be worth it as other areas might compromised.

I would consider patching then cutting out affected area but have no experience of this type of repair.

The top and bottom skins are held together by a myriad of fine threads. If it is "delaminating" it means the threads are broken in that area. I would think it can't be repaired. Live with it or replace the floor.

Does your airdeck have a quilted appearance, small diamond shapes, or is it the later, smooth finish with non-slip patches stuck on? The former type has two layers on both top and bottom. I am guessing that air has penetrated the inner layer and blown up the outer. When I had this type it always leaked a little but never developed blisters. Mine went sticky after five years and was replaced. You might be able to cut away the outer surface and glue a replacement on but I suspect it would be tricky. The material is pvc, even though the dinghy tubes may be Hypalon.

Mine is the smooth one, I was wondering if I could cut out the blisters and use the blisters themselves as patches after all they don't have holes in them, I didn't realize that they were PVC? do you know what the inner body of the floor comprises?

As Stork III says, the upper and lower skins are held together by thousands of threads, maybe one per square millimetre(?). I suspect that the threads are attached to an inner skin with the weatherproof outer glued to that. I would be surprised if both skins were not PVC or some similar polymer but I don't know for certain. Your idea of cutting the blisters out and re-using them sounds feasible.
