If you are gluing laminate along walls that are not straight this is normal. You must take the time to cut the plastic laminate Formica to fit the inconsistencies of the curves on the walls. It is a very rare case for the drywall to be straight. Make sure to allot plenty of time to do the job correctly. NO RUSH JOBS ALLOWED HERE!
The method taught in this video for scribing a plastic laminate countertop backsplash cap to fit tightly to the walls can be used for every area of kitchen or bathroom vanity cupboard lamination work.
What I mean is, if your vanity or kitchen cabinet side has a void area where the mica meets the wall, when you are resurfacing, just use the same method to make it fit to the crooked wall. The same applies to floors that are not level and walls that are not plumb.
This video demonstrates the use of hand cutters. You can buy these at a hardware store. Cutting Formica with these tin snips is an acceptable method commonly used in the cabinet industry. The scissors are utilized more for fitting plastic laminate on kitchen resurfacing jobs more than any other type of laminate work in the industry.
Kitchen and bathroom vanity cabinet and countertop installers have used these cutters for decades to sever the plastic while on the job site.
You can find Formica cutting hand tools that are a lot more expensive and do not cut as efficiently as a good old pair of tin snips from Home Depot or Lowe’s. These specially designed scissors are designed to cut “clean” cut both the left and right edge of the cut. Although the look impressive and come with a hefty price tag the tin snip style cutters work better than these over priced laminate shears.
