    Hi, I am about to install Roppe #175 vinyl/rubber T molding with metal track as a transition between two floors. I am going to have a few mitered corners in which I would like to use a contact adhesive on the T molding joint to help keep it joined. I don't want to use this against the floor surface due to floor contraction. Roppe T molding appears to be more of a rubber product than vinyl due to feel and flexibility. Although, it's found under vinyl accessories on their site. The company really doesn't state what the actual material is (link below). I would like to know if you have any suggestions for a great clear contact adhesive I could use on the joint as well as the track area just below the joint? Thanks, Ray

    most "rubber" products are vinyl anyway.. so not much worry there. I have used crazy glue in the past to hold mitres when I make them.

    The biggest thing I’ve found for minimizing shrinking is that you have to compression fit the reducers. Super glue is what I also use to keep my corners tight. Blue tape the reducers so the inevitable squeeze of CA adhesive doesn’t goober up the top side of your brand new reducers. I don’t bother to put any adhesive in the track itself. I’d think that’s just asking for trouble.

  4. The product is what is termed thermoplastic rubber. True thermoset rubber cannot be extruded, it must be molded which is a slow and costly process. They add just enough SBR (Styrene-butidiene)rubber to the vinyl mixture to give it a bit of flexibility.

    However, it is still, for the most part plastic. This means that 99% of the solvent based contact cements won't work long term to hold the product together. Eventually the solvents will cause a problem called "plasticizer migration". This causes the adhesive to re-emulsify and release.
