Installing Laminate Countertops

Build a laminate countertop from scratch

Build a seam-free laminate countertop

Laminate is a budget-friendly alternative to granite, quartz and other solid-surface countertops. And building custom countertops in place is a great way to deal with unique shapes and sizes. There are hundreds of colors to choose from, and you can order 5 x 12-ft. sheets of laminate at most home centers. With a sheet that size, you can avoid cutting difficult miters, and usually eliminate long, crumb-catching seams.

If you've never tackled custom countertops, don't be intimidated—let our expert walk you through the process. You'll need a couple of specialty tools, including a compound router with an offset base, a laminate slitter and a laminate file, but the several hundred dollars you'll save by installing your countertops yourself will be more than enough to pay for these tools. And just think of the bragging rights!

Figure A: Anatomy of a Countertop

Before you assemble the underlayment, plow a 1/4-in.-deep, 1/4-in.-wide dado into the backsplash (Figure A). The laminate slips into the groove to give you a little wiggle room when you install it. Jamey cuts his dado by making a few passes on his table saw.

Routing Tip

When you trim the main countertop and the top of the backsplash, the guide of your router bit will be running along finished laminate, so keep the router moving. If you stop for any length of time, the bit will grind into the surface of the laminate. Jamey rubs a little petroleum jelly along the edge where the bit rides to prevent marring.
