Color Match Silicone Sealing To smooth out a seamfill bead with
your finger, dampen a paper towel
with rubbing alcohol and then
dampen your finger. Next, run your
finger along the bead of seamfill,
wiping any excess silicone onto the
paper towel.
The rubbing alcohol will keep the
silicone from smearing.
After the seat is secured in place, it may be necessary
to support or brace the seat against the wall until the
adhesive silicone cures. Then use the Onyx color
matched seamfill to fill the seams between the seat
and the walls.
Dry Fitting Mark with Tape&
The painter’s masking tape will help
keep the silicone from being spread
on the wall panels.
With the seat resting on the wooden supports and the
position and fit is satisfactory, the seat must be
siliconed into place. We recommend putting masking
tape around all the edges of the seat to help with
placement and clean-up of the silicone.
Adhesive silicone
Seat Supports
Remove the seat and apply a bead of silicone on the
shower walls, about ½” inside of the edge of the
masking tape. Place a bead of silicone on top of the
wood supports as well. Place the seat back onto the
wood supports. Silicone may press out in places.
Remove the masking tape, being careful to remove
the excess silicone.
Mounting Adhesive Silicone&
If excess adhesive silicone gets on
the walls or seat, it can be cleaned
up using rubbing alcohol and paper
towel.
Dry Fit Seat & Check Level
If the seat needs to be belt sanded,
masking tape is often used to help
mark the line.
Place the seat on the wood supports. Ideally, the wall will
be square and everything will fit perfectly. If the wall is
out of square slightly, color match silicone can cover the
small gap easily. If the wall is out of square more than ¼”
overall, we recommend marking the seat (top and
bottom) and using a belt sander to fit the seat to the
corner. Check the seat with a level. The seat design has
certain slopes to allow the water to drain towards the
