How to Remove a Glued Down Vanity Top

Removing a glued down countertop can be challenging if the glue was applied to the entire top edge of the base cabinets that the countertop sits on. No special tools are available to remove a countertop, but you can follow some steps to help the removal process go smoother and to avoid damaging the base cabinets. Before removing your countertops, remove the backsplash first. Care must also be taken when removing the backsplash to avoid damaging the drywall.

Removing a Glued Countertop

Step 1

Use your box knife to cut the caulking between the backsplash and the wall. Place the edge of the putty knife between the backsplash and the wall, and then use your hammer to tap on the handle of the putty knife. This will cut the glue that is holding the backsplash to the wall. Continue this process down the entire length of the backsplash. Use your flatbar to carefully pry out on the backsplash after you have cut through the glue.

Step 2

Place the putty knife between the underneath side of the countertop and the top edge of the base cabinets. Use your hammer to tap or hit the handle of the putty knife. Your goal is to break the adhesive bond without damaging the base cabinets. Use your flat bar to pry up on the countertop as you are breaking the adhesive bond. Slide your putty knife underneath the flat bar when you are prying up on the countertop. This process will keep you from scratching or tearing up the base cabinets.

Step 3

Use a circular saw to cut out the countertop. It may be necessary to use a saw to cut out the majority of the countertop. This will give you more room to pry up the edges. Set your saw blade to 1/4 inch deeper than the thickness of the countertop. Start cutting from the hole in the countertop where your sink was located. Make sure that you know where the base cabinets are located to avoid cutting them with the saw.
