How to Make Prefab Vanity Countertop Fit Non Straight Wall
If you have purchased a countertop from Home Depot for your vanity there’s a possibility that the wall will not be straight that you will be installing it on. Many of the tops are made out of fiberglass material and they have the sinks pre-molded into the counter. If you place the top into position on top of the bathroom vanity cabinets and there are gaps along the wall, it’s because the walls are not straight.
Tools Needed to Make a Prefabricated Vanity Countertop Fit
1) Belt sander
2) Fifty grit sand paper belts
4) Dust mask
5) Saw horses
6) Eye goggles
7) Long sleeved shirt
Procedure for Fitting Top to a NON-Straight Wall
Place the top into and get it aligned perfectly straight with the front of the bathroom vanity cabinets. Using a pencil start at one extreme end, place it tight (flat) to the wall and let the lead rest on the backsplash of the countertop.
Keeping the pencil tight to the non-straight wall begin to pull it along the contour so that it marks the top of the prefab countertop’s backsplash in relation to the humps and dips in the bathroom wall.
Remove the top and take it outside. Place the prefabricated fiberglass countertop flat on the saw horses or something else to support it as if it were resting on the vanity cupboards.
With your dust mask on, begin sanding the vanity counter with the belt sander equipped with the fifty grit sanding belt. You should be holding the tool in a vertical position where it is only touching the surface of the top with the three inch width of the sanding belt. Sand the countertop down to the pencil mark all along the edges of the countertop.
It is a great idea at this point to be wearing a long sleeved shirt and eye protection. The dust particles will be very fine and will get into your eyes and the pours of your skin if you do not protect yourself.
Sand the Home Depot countertop down to the pencil mark all along the edges of the countertop.
Take the fiberglass prefabricated-vanity-top back into the bathroom and place it on the cupboards. Push it into position and you should have a perfect fit to the non-straight walls. If there are still gaps, mark the countertop again and sand off more of the fiberglass so that the prefab counter will fit correctly.
