How to Install Schluter-DECO-SG Metal-Edge Profile for Tile or Glass

June 22, 2020


Schluter-DECO-SG profile can be used to support glass panels or to create an attractive shadow gap between tiles

DECO-SG is available in anodized aluminum and stainless steel.  The channel of the profile is offered in two widths, 1/2" and 9/16". This enables the use of glass panels up to 3/8" and 1/2" thick, respectively.

In this video, we use DECO-SG on the wall and floor to support a glass panel in a curbless shower application.  

Our shower has already been prepared to receive tile including the installation of the Schluter-Shower System and Schluter-DITRA uncoupling membrane. Work on the tile installation has already begun. 

The Schluter®-DILEX-EKE corner movement joint was installed up to the planned location of the DECO-SG.  We selected the profile height according to the thickness and format of the tile and width according to the thickness of the glass panel.

First, we’ll measure where the DECO-SG profile will be installed on the wall. We must avoid any overlap of the anchoring legs where the profiles meet at the floor to wall transition because this will interfere with the tile installation.  Transfer the measurement to the profile.  Remember to always observe all safety instructions and standards.

Since we are using the anodized aluminum version of the DECO-SG, we will be using a miter saw with a non-ferrous blade to cut the profile.  For best results, cut the profile slowly. An accurate cut helps ensure a clean installation. Then, file the cut end of the profile to remove any burrs.  Keep in mind, different tools will be required depending on what profile material you are using.  Aluminum and stainless steel can be cut using a variable-speed angle grinder, set to the lowest speed, with the Schluter-PROCUT-TSM cutting wheel. A third option for aluminum is to simply use a hacksaw with a bimetal blade.  

Dry fit the profile before moving forward.  Metal snips can be used to cut away the anchoring leg to avoid any overlap.

We used a level to ensure our profile is plumb and placed a mark on the wall where it will be installed.

Using a notched trowel, apply thin-set mortar to the area where the DECO-SG will be installed.  Firmly press the anchoring leg of the profile into the thin-set mortar.  Next, we trowel additional thin-set mortar over the anchoring leg. This is necessary for full coverage and support of the tile edges.

Solidly embed the tiles into the thin-set mortar, so that the tiled surface is flush with the top of the profile. Leave a space of approximately one-sixteenth to one-eighth inch for grout.  Don’t forget to remove excess setting material from the profile immediately to avoid any damage to the finish.

Take care to align the profiles, paying close attention to the area where they meet.

Once the tiles have been set and grouted, the glass panel is inserted into the channel of the DECO-SG, as per the glass panel manufacturer requirements.

As you can see, not only will DECO-SG support glass panels, it also provides discreet and elegant lines within the tile assembly.
