Re: Best way to cut a formica countertop
Use a fresh, sharp blade in a circular saw, mark your cut line on the back, cut the splash first, then make the cut from the front edge to the backsplash.
If you use a straight edge to guide the saw, the cut should be smooth enough to install an end cap if necessary, otherwise polish the edge with a belt sander before installing the end cap.
If fitting the counter between two fixed points, you're going to want to scribe both ends onto a template, transfer the template to the underside of the countertop, and make the cuts, this way there will be minimal clearance to caulk. IMHO, when counters butt into a wall, it is best to install an end splash, this will not only cover any gap, it will finish off the countertop nicely.
I suffer from CDO ... Its like OCD, but in alphabetical order, LIKE IT SHOULD BE!!!
