How To Join Laminate Countertop Corners

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.

How to join laminate countertop corners.

They let you position the sheet exactly before gluing it down. Cut the tops to length and apply glue to the laminate ends. Sand down any rough edges with a sander or file. When it dries set a sheet on dowels placed on the substrate.

Place the two sections of countertop on top of the sawhorses so the laminate side is facing up and the corners are together. Use an angle square to determine the perfect 45 degree angle. Mark the miter angle on the back of the laminate countertop. You ll end up with a small burr on the bottom edge of the laminate.

Using the straightedge draw a line on the countertop between the l s inside and outside corners. However carpenter s glue sets up more quickly. Mark a straight pencil line along this straight edge. Measure and cut the laminate countertops to the desired size.

I haven t seen anything that shows how to trim tight spots such as the side edge of the laminate up to the wall. When connecting two pieces along a run such as in a galley kitchen make the cuts straight across at a 90 degree angle. Check the underside of the miter joints to ensure the mortise joints align as well. Spread contact adhesive on the countertop substrate and both sheets of laminate.

Apply yellow carpenter s glue or liquid hide glue to both edges of the mitered joint and reposition the two sections. I ve seen where after you stick the laminate to the counter you trim it with a router. Before you join the pieces mark the ends where you need to cut them to length. This must be done on the back of the countertop because this is the side.

For joining in a corner the pieces should be cut at a 45 degree angle. Either glue works well.
