There are a couple of different methods used to install laminate countertops.
Installing laminate countertops corner.
If your countertop turns a corner it probably has two pieces each with a 45 degree angle or miter cut.
Attaching laminate yourself can be a little risky but you ll save yourself a nice chunk of money if you go this route.
Installing a mitered corner on a countertop.
The point where two counters meet in a corner must be square.
When you measure for your countertop be sure to include the counter overhang which is usually between 3 4 1 inch in front and on open ends.
If you re installing a new sink or range top use the template that comes in the box.
Cut the tops to length and apply glue to the laminate ends.
If you need to make a cut out for the sink and range top use the old laminate countertop as a guide.
Place the two sections of countertop on top of the sawhorses so the laminate side is facing up and the corners are together.
If your sink or range top did not come with a template set the item upside down on top of the new countertop.
Check that the fronts and backs of each piece align with each other.
These cuts meet to form the 90 degree corner.
You can get your cabinets prefabricated and screw them in or you can laminate wood countertops yourself.
