Questions about heat and toilet floor area

<< < (3/3)

Keith Oliver:
I woould not use polyester resin.  I would use epoxy, with thickener, then you will have a solid substrate into which you can drill holes for the bolts.  If you are unsure where the rot ends, use a penetrating epoxy on the exposed edges of the wood first.  When you use an epoxy to seal the wood, the polyester resin may not adhere effectively, so using epoxy for the rest of the job ensures a good bond.

John Padmore:
I agree that epoxy resin would be better. I will go with that. Also decided to insert bolts for the flange instead of using screws to hold it down. The heads will be immersed into the epoxy resin for stability. Just have to make sure the gasket will seal properly. I removed all of the wood down to what looks like insulation so there will be plenty of epoxy to hold things together. I might just install a seatbelt while I'm at it!  8)

Richard And Babs Ames:
The fiberglass guy's recommendation. To be sure have clean unrotted wood to adhere to and use a product called Liiquid Transom. He also stated that you need to take up a larger area including some of the floor to get a lasting fix. You need to have a good large base to attach the toilet.

Richard And Babs Ames:
Liquid Transom is available at Marine supply stores.
