Installation Instructions for the plumber or DIYer during “rough in”
The plumber should be installing the Guide during “rough plumbing”stage. This is preferred. There are no ANSI specifications for the tile installer to tile up to the flange. There are always gaps. These gaps become water ways when the wax rings leaks. Eventually all wax rings leak. When there is water damage or leaks the plumber is called not the tile installer. The plumber can easily seal the floor around the flange protecting the floor and the tile guide will be in place for the tile installer making his job easier.
If the toilet that is to be installed is available the plumber can check to see if the footprint of the toilet will cover the guide. 99% of toilets will cover the guide. If the toilet has not been purchased and since the plumber has to come back to install the toilet it would make sense to remove the dogears. Use a T-Square to align the guide around the flange using the back wall as a guide. The label has been removed for this demonstration so that you can see better.
Start placing the adhesive by putting a bead of mold resistant silicone adhesive around the flange. This flange had cut outs. Fill all cut outs with the silicone to seal the perimeter of the flange.
Use plenty of silicone going around the flange and then put adhesive onto the penciled outline. Put more adhesive in open areas.
Remove the eyelet and place the guide into the adhesive. Push the guide firmly so that the adhesive comes through the screw holes on guide. Remove the adhesive from the perimeter so that the tiles can butt up against the guides edge. Align with the T-square. Using screws is optional.
For the DIYer or the Professional tile installer if the Guide is NOT already in place.
Push the Guide into the silicone. Clean the perimeter of adhesive overflow. Using the previous placed tiles as a guide and use a T-Square to align.
Finish tiling up to the guide making only straight tile cuts. Leave the debris shield on until you are ready to install the toilet.
