Due to manufacturing variations, we cannot guarantee an exact color match from lot to lot. Prior to installing DumaWall panels and trim to your walls, please unpackage & lay out all purchased product to ensure color consistency.

If you are using corner and/or L-trims for a DumaWall shower kit installation, this guide will show how to install the last, short tile at the end of a row. Read and follow this guide if your project looks like this:
The challenge is to place the remaining tile section into the edge trim while also getting the interlocking tile edges locked together.
First, install the inside corner trims into each corner using adhesive. Allow 24 hours for the adhesive to cure. Make sure the corner trims are oriented as in the image below. Each inside corner trim piece has a full and a partial channel. The full channel will be against the back wall.
Next, determine the length of the tile section. Measure from the inside lip of the previously installed tile to the inside edge of the pre-installed trim. See image at left for details. In this case, the length to cut the final tile in the row is 4-3/4-inches.
After cutting tile to length, apply adhesive to the substrate, as shown. Spray a squirt or two of water onto the substrate and adhesive, as shown. This will lubricate the substrate allowing for easier movement.
Insert the cut tile edge into the L-trim while holding the inter-locking joint edge away from its mating tile.
Push the tile into the edge trim while laying the tile down toward the substrate. When pushed into the trim entirely, the inter-locking edges will be exposed.
Apply DAP® Kwik Seal Ultra (sealant) to the interlocking edges if this installation is for a wet environment.
The tile can now be manually pulled into place. Pull the tile toward the inter-locking joint. If necessary, rubber gloves can be used to increase grip friction with the surface of the tile. See image below. Keep pulling until the inter-locking joint is tight.
Use a damp rag or paper towel to clean off any sealant or adhesive that may have been squeezed onto the tile surface.
DumaWall Edge and Corner Trims
Inside Corner Trim
Inside corner trims should be attached with adhesive to the substrate. Dispense a small bead of adhesive directly to the substrate corner or on the trim itself. Also dispense a bead of sealant into each of the trim’s channels to prevent water from reaching the substrate.
Universal J-Trims are used to finish the terminal end of tiles when not adjoined to anything. To install, don’t dispense adhesive a few inches from the tile’s edge where you intend to use the Universal J-Trim. This will allow the trim to slide in-place. Dispense a bead of sealant into the receiving channel of the trim and then press the trim into place.
L-Trims are used to cover existing exposed tiles to provide a finished look (see drawing below). Install by dispensing a thin bead of sealant on the DumaWall side and a thin bead of adhesive on the substrate side. Press trim into place. If trim will not stay in-place, use some masking or painter’s tape to hold until adhesive sets.
