Due to manufacturing variations, we cannot guarantee an exact color match from lot to lot. Prior to installing DumaWall panels and trim to your wall, please unpackage & lay out all purchased product to ensure color consistency. If you encounter unreasonable color variation, please give us a call at 1-800-434-3750 (7am-4:30pm CST, M-F) so that we may assist you with your project.

Inside Corner

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.

J-Trim

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 into place. Dispense a bead of sealant into the receiving channel of the trim and then press the trim into place.

L-Trim

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.
