Thanks for the reply Dahlea, I am excited about trading with you... It is kind of intimidating to negotiate, but if you don't ask for what YOU WOULD LIKE~~~~ it really minimizes the chances that it will happen. So be assertive and air your concerns, be honest and forthright. This is a great forum that was in high demand for a LOOOOOOOONG time. Now that we have it we should use it! Go ahead, you will enjoy it Carolyn the Gardninlady

Right in the specs for Thorocoat it states "Vertical and overhead surfaces". It is not for a porch floor.

You could try it. Tap con preasure treated stringers to the slab,screw the ipe to them. J.

Measure diameter of hole and multiply by 3.5. Cut a piece of flexiable plastic or heavy cardboard or metal roof flashing long as number found above X twice the thickness of tank cover. Work strip to snuggly fit inside tapered hole making sure lower edges line up ( top edges will miss-alighn where they meet but it doesn't matter.) Use duct or other strong tape to join ends. Wax inside ring and set on waxed plywood. Fill ring 3/4trs full of sackcrete and bury wire reinforcmet and handle in it before it sets. You might have to lightly agitate concrete to make sure ring form is round. Many people just lay flat rot resistant material over the hole which seems to work fine.
