[awab]

dear readers,
I hear alway epoxy. I am only lost when it come to buy the right product. There are so many out there.

can somebody share his opinion about how to treat the undership.
I got it cleaned quite well with a hot water pressure cleaner. Everthing what s left is very strong. I was thinking to treat as a primer/ sealer the cement with CPES and then antifouling. For you thoughts I would be thankfull.

There are some epoxys specially formulated to waterproof cement water tanks. I would check with paint companies.
