WE have a jaquzzi tub, it was here when we bought the house. The brand name is novi, we have aproblem with the caulk bead retreating from the tub when filled with water. I can caulk it and it will last for about a month then it will start to peel away thus allowing water to get behind it then trickle down to the kitchen ceiling. WE are renovating the kitchen (read toilet supply rupture thread) and while I have great access to the bottom of the tub I thought maybe I should look into this fix. As I looked at how the tub is sitting, first there is the t/g floor boards, then a layer of what looks like cement then a piece of plywood, a piece of styrofoam another piece of OSB. All this looks like it is attached to the bottom of the tub with the same resin that was applied to the underside of the tub. Is this normal or is only the OSB attached at the factory to the tub as a platform. What I am thinking is that the styrofoam is compressing causing the cualk to separate.
Any ideas before I hang the new ceiling?
