When you’re ready to start hanging, to pull off this trimless door look, you will have to include a certain amount of setback from the edge of the drywall to the door jamb to accommodate the Z Shadow Bead. The amount of space left here depends on the size of the Z Shadow Bead you choose — there are 11 versions of the bead available, all of which are listed on the product overview on the Trim-Tex website, where you’d consult the “B” size of the version you end up using. The gap you leave here must be 1/8" wider than the overall width of that “B” size of the Architectural Z Shadow Bead. (In the trimless door we finished this way, pictured at the top of this article, we used the 5/8” x 3/8” version of the bead.)
Now that you’ve prepped your doorway, it’s time to cut your bead down to size to create a trimless door with Architectural Z Shadow Bead, and there are a couple ways to go about doing that.
USING A MITER SAW
Just cutting right into this vinyl bead with a miter saw will often cause it to bend, leaving you with an inaccurate angle. Instead, we’d recommend grabbing a scrap piece of drywall the same thickness of the bead and slotting that into the bead’s profile to support the Architectural Z Shadow Bead when cutting with a miter saw. Make sure that the miter saw has a fine-tooth blade (100-plus teeth) before beginning.
