How to install wedi Sanoasa Bench 4

The Sanoasa 4 is a suspended bench that allows a design creating more space in any shower while adding suspended seating

comfort and can carry up to 500 lbs of weight across once it is tiled. The Sanoasa 4 is 3 1/8 in. thick and 47 1/4 in. long. The

bench comes pre-sloped on its surfaces so water can safety run off to the front of the seat where it can move towards the shower

drain instead of causing puddles on the bench tiles. The Sanoasa 4 can be cut to a shorter length and made-to-fit between three

shower walls where the bench connects. This bench is ideal for installation prior to tiling but can also be installed over existing

tiled walls. In the latter case, there is a risk the waterproofing of the walls may be damaged by the Sanoasa fasteners which are

difficult to seal like in most retrofit installations where fasteners penetrate through tile and waterproofing below the tile. This

bench can carry up to 500 lbs. of load on its surface once tiled without creating a risk for cracks in grout or tile. The larger and

thicker the tile and stone, the more it adds to stiffness and load capability of this bench. A minimum tile size of 4 inches should

be used and tile should be a minimum of 1/4 in. thick.

5. After 24 hours, tiling can commence to include the

underside of the bench.

1. Cut and dry-fit the bench into the three-wall opening in the shower. Dry fit with the two L-shaped steel profiles loosely fitted

onto the sides of the bench. Mark the outline of the bench where it will connect to the walls so you can see later where to

apply wedi Joint Sealant.

2. Determine installation height and apply wedi Joint Sealant widely over the wallboard area where the steel profiles will be

installed. Press the steel profiles into position.

3. Install steel profiles in a level position. Apply wedi fasteners through the steel profiles and wallboards into framing spaced 16

in. o.c. apart.

4. Apply wedi Joint Sealant widely to all areas connected with the bench (all three walls and to both steel bracket surfaces). Insert

the bench and press into the bed of sealant. Ensure the bench will stay in a tight position to allow the sealant to bond. Apply

a 1/2 in. bead of sealant over and along all transition seams between wall and bench including on the underside of the bench.

Finally, apply wedi mesh tape on all such seams. The mesh tape is later covered with thin-set mortar. Allow wedi Joint Sealant

24 hours to cure.
