Treadmaster blisters

[hpeer]

I put down some treadmaster, 8 pieces each about 1 foot by 3 feet. I did this about 3 months ago, then left. Now that I am back a couple of the pieces have a blister or two. Apparently I was stingy with the epoxy.

Any suggestions on how to repair short of rip up and start over?

Mask entire top off, inject with epoxy, then vacuum bag. Make sure everything inside the bag is well masked for squeezeout. Use thinned epoxy and a needle for injection. Done right it should only leave the needle hole full of epoxy. If you can't bag it, use something flat with weight on it.

I was thinking dive weights?

Any special type epoxy?
