replacement caulking or sealant?

We are replacing our outside shower box and faucet. What do we use to seal or caulk around the box? Can this also be used to caulk/seal around a new city water inlet device?

Thanks!
  • Butyl tape, don't confuse it with the cheap putty tape, they aren't the same. Putty tape dries out and fails in time.
  • If you can't find ProFlex locally, OSI Quad from Lowe's or HD is just as good if not better. And it's half the cost too!
  • First put butyl tape around the perimeter of the box that sits flush with your side wall.

    Once the box is attached and the butyl tape squeezes out the sides, trim the excess. Let sit for a day, then check and trim again (sometimes more will squish out).

    Finally apply a bead of RV approved sealant (Geocell Proflex is great) around the top and sides of the box.

    Done and Done!
  • Don't use anything with Silicone. Use Geocell Proflex! Yes, you can use this stuff to caulk, reseal anything on the outside walls of the RV. The roof requires something different!
