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. For joining in a corner the pieces should be cut at a 45 degree angle. Cut the tops to length and apply glue to the laminate ends. Mark a straight pencil line along this straight edge.

Place the two sections of countertop on top of the sawhorses so the laminate side is facing up and the corners are together. When it dries set a sheet on dowels placed on the substrate. I ve seen where after you stick the laminate to the counter you trim it with a router. Check that the fronts and backs of each piece align with each other.

Measure and cut the laminate countertops to the desired size. Mark the miter angle on the back of the laminate countertop. Before you join the pieces mark the ends where you need to cut them to length. However carpenter s glue sets up more quickly.

When connecting two pieces along a run such as in a galley kitchen make the cuts straight across at a 90 degree angle. Remove the burr with a file so the laminate will glue down completely flat. 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. Either glue works well.

Check the underside of the miter joints to ensure the mortise joints align as well. You ll end up with a small burr on the bottom edge of the laminate.

This must be done on the back of the countertop because this is the side. I haven t seen anything that shows how to trim tight spots such as the side edge of the laminate up to the wall.
