  • oops i fogot to install the plaster ground. Help.

    When installing my moen shower, faucet etc i forgot to install the plaster ground in or behind the wall. I am able to install and fully attach the 2 screws through the face plate and that is tight and firm. My opening is only 2 inches so i would have a really hard time cutting through tile and hardi backer to install the plaster ground. Verything is attached and working fine so do i need to go the trouble of getting the Plaster ground installed. Thanks.

      When homes were plastered these were on the edges of doors and windows for the plasterer to float the plaster off of. Moen is misusing this specific word. And it was proven by this thread. Nice to be an old fart some Tue. Morns. Good Day!

          basically it's the plastic trim used as a spacer for the tileman to float his cement to. it does a few things.

          it protects the valve from getting full of cement. it acts as a minimum / maximum distance the valve can be installed in the wall and still allow the trim to work without an extension or shallow trim kit. and it also allows the tileman to float to it and provides the clearance for the access later on, but still allows the trim to cover the hole with the finish trim.

          on some valves it also tucks in behind a fiberglass shower surround and adds support and rigidity to the cut out.

          tony it would be easier to just show you in person

          if you have the valve ruffed in the proper depth and you make sure there is proper access for service and not too much access to make the trim not cover, then i wouldn't be too worried. now if this was done on new construction with multiple units and tradespeople, i would be very concerned about them missing. on a simple single family home with the ability to check the tile float, i wouldn't be too concerned for mistakes. just make sure the trim covers, the valve is accessible and the depth is correct for the finished tile and trim.

                The plaster guard does indeed serve a use. There is a gasket on the back of the circular chrome trim which needs to butt up against something firm
                to create a good seal. Without the firm fit, the gasket will sort of work, but at some point in the future (22 years for one of my Moen valves),
                the gasket comes loose from the trim, and water leaks behind the valve (down to the ceiling in the room below, in my case!).

                I jerry-rigged a plaster guard substitute out of a circular piece of stiff plastic; am installing this afternoon.

                  Gee Tool, it is fun to disagree with you on a Wed. afternoon...Moen is using a correct term. Before the days of backer board, hardi board or whatever, the tile setters used to line the shower with wire lath and "plaster" the walls with a cement based plaster and then set their tile to it. Hence Moens terminology fits.
