How To Join Laminate Countertop Corners

Before you join the pieces mark the ends where you need to cut them to length.

How to join laminate countertop corners.

Apply yellow carpenter s glue or liquid hide glue to both edges of the mitered joint and reposition the two sections. You ll end up with a small burr on the bottom edge of the laminate. Rout a straight edge on one piece of laminate photo 1. Place the two sections of countertop on top of the sawhorses so the laminate side is facing up and the corners are together.

Sand down any rough edges with a sander or file. In most of the videos i ve seen the counters are removed or if they re not removed they simply show how you trim the front edge with a router. Check that the fronts and backs of each piece align with each other. I ve seen where after you stick the laminate to the counter you trim it with a router.

Spread contact adhesive on the countertop substrate and both sheets of laminate. Either glue works well. Check the underside of the miter joints to ensure the mortise joints align as well. For joining in a corner the pieces should be cut at a 45 degree angle.

Mark the miter angle on the back of the laminate countertop. They let you position the sheet exactly before gluing it down. Use an angle square to determine the perfect 45 degree angle. However carpenter s glue sets up more quickly.

When it dries set a sheet on dowels placed on the substrate. I haven t seen anything that shows how to trim tight spots such as the side edge of the laminate up to the wall. Remove the burr with a file so the laminate will glue down completely flat. Using the straightedge draw a line on the countertop between the l s inside and outside corners.

Cut the tops to length and apply glue to the laminate ends. When connecting two pieces along a run such as in a galley kitchen make the cuts straight across at a 90 degree angle.
