In Part 3 of this series of articles on how to build a custom laminate countertop, you learned how to apply the laminate material to the countertop base andto trim the excess material. In this 4th and final part, you will learn how to finish the laminate covering by sanding the edges and touching up the corner and to install your new custom countertop on the cabinet base. Follow the simple steps below to complete this project.

Step 1 - Place Countertop on the Cabinet Base

Have a couple of friends help you carry the countertop and carefully set it on top of the cabinet base. Make sure that the sides of the countertop are positioned correctly and that the back of the countertop is flush against the wall where will it be installed.

Step 2 - Secure the Countertop to the Cabinet Base

After you have the countertop and position, make sure that all the drawers and doors on the cabinet base had been removed. Then, crawl underneath the countertop and begin screwing screws into the bottom of the countertop base. When inserting screws into the bottom of the base, make sure to screw through supports pieces of wood on top of the cabinet base. Don't be afraid to use a lot of screws to securely attach the countertop to the countertop base. However, try to make sure that the screws are evenly spaced—just in case you need to remove them in the future.

Step 3 - Caulk the Rear of the Countertop

Take some silicone caulk and a caulk gun and carefully place a bead line of caulk along the rear of the countertop. Try to apply the caulk as neatly as possible. You can also use your finger to help smooth the caulk if you make a mistake.

Step 4 - Use Rolling Pin on Laminate Material

After you are finished with the caulk gun, take the heavy rolling pin and again use it to help press down the laminate material into the countertop base. Go over the entire surface of the countertop as well as the edge facing on the front and sides of the counter.

Step 5 - Sand Edges of Laminate Material

Use the sanding block to sand away rough edges where the countertop laminate material meets the material placed on the edge facing pieces. If you made a mistake with the router, you can use a file to file away large bits of the material, and then use the sanding block to clean them up.

Step 6 - Sand and Clean Up Corner Edges

You should pay particularly close attention to the corners of the countertop. If the edge of the laminate material appears to peeling away from the wood, apply additional contact cement as needed. Use the sanding block and file to carefully get rid of rough or sharp edges on the corners of the countertop.
