Installation Instructions
1■ Build a form for making your countertop using ¾” Melamine coated particleboard. Cut strips for
the sides 1 ½” – 3” wide to match the desired countertop thickness.

3■ Sink Cut Out (if required – otherwise, skip to step #4): Make a sink cut out by using extruded
foam equal to the depth of the form. Use a jigsaw with a metal cutting blade or a hack saw blade
with handle to form the cut out. The cut out should be sanded to remove any rough spots and taped
carefully with clear packing tape. Smooth out any air bubbles, etc. as they will transfer to the sink
opening. Faucet templates can be made using PVC pipe wrapped in thin sill plate foam and
wrapped with clear packing tape using the same procedures used for the sink.
2■ Drill guide holes on the side boards from the top down and assemble the side panels to the
bottom panel using 2” coarse drywall screws. Fasten the sides of the form to the base using coarse
screws allowing for the depth of the countertop and fastening securely to the base. Fasteners
should be located every 6-8 inches around the perimeter.
Note: If the countertop will be positioned against walls that may not be square, we recommend
creating a template out of cardboard first and positioning the sides to match the template.
