In most homes the walls are not square, straight or even. This is due to the home settling, twisting beams or carelessness on the part of the builder. Uneven walls create gaps between the wall and the straight, even countertop, resulting in a messy and amateur look. Fortunately, an easy fix will make the countertops look neat, even and professional.

Instructions

  1. 1

    Place a large sheet of heavyweight paper over the countertop area and tape in place with light-tack masking tape.

  2. 2

    Cut along lines with a utility knife, creating a paper template with uneven wall lines.

  3. 3

    Cut the countertop with a circular saw, following the uneven markings, which will coordinate perfectly with the uneven wall.

  4. 4

    Mount the custom-cut countertop, tightly butting it up to the existing wall.

  1. 1

    Load a caulking gun with paintable silicone caulk by inserting the tube of caulk into the caulking gun with the tube nozzle pointed away from the trigger.

  2. 2

    Place the tip of the caulking tube up to the beginning of the gap and squeeze the trigger while moving the caulking gun along the gap.

  3. 3

    Press the caulk into the gap with a flexible putty knife to make it smooth and even with the wall and countertop.

  4. 4

    Allow the caulk to dry fully.

  5. 5

    Brush on matching paint with a small paintbrush.

  1. 1

    Glue wood shims into the gaps, sitting 1/4-inch below the edge of the gap to give the caulk a seat, with all-purpose adhesive.

  2. 2

    Allow the glue to dry fully.

  3. 3

    Apply a bead of paintable silicone caulking over the wood shims ending just above the countertop surface.

  4. 4

    Press the caulk in place with a flexible putty knife, making it smooth and level with existing countertop.

  5. 5

    Paint the caulk to match and blend with the countertop.

Tips and warnings

  • Always choose a paintable silicone caulk in order to match the countertop colour and paint.
  • Wear protective eyewear when cutting countertops.
