How to Seal the Edges of Kitchen Formica Countertops

Kitchen Formica countertops are available in a wide range of materials, including laminate and other solid materials. Formica is the first company to have produced laminate countertops, and its products are known for their durability and sustainability. Some people may wrongfully use the term formica for laminate, but these two terms are not equivalent. There are also other companies that produce laminate countertops. If you would like to seal the edges of your laminate kitchen countertop, you need to determine the types of edges that you have.

Step 1 – Clean the Countertop

Clean the countertop before sealing. Use 50 ml of dish detergent in 3 liters of water and spread the cleaning solution on the countertop and the edges as well. Employ a soft brush and stay away from wire brushes, which could scratch the laminate surface. Rinse the countertop and wipe dry with a clean piece of cloth. Allow the surface to dry before you start applying sealant.

Step 2 – Determine the Material Used for Countertop Edges

The laminate countertops are made of a particle board that is coated with a synthetic material. The edges may be made of wood or laminate, or a combination of these two materials. The wood edges require a different type of sealing than the laminate edges.

Step 3 – Seal Laminate Edges

If you determine that the edges of your kitchen countertop are laminate, use gel gloss and a soft sponge to seal the edges. Use circular moves when applying the gloss and make sure to cover the entire surface of the edges of your countertop. Get a clean piece of cloth and wipe the gloss off the edges of the counter. Make sure no sealant is left behind, as this can attract dust and debris.

Step 4 – Seal Wooden Edges

Wooden edges are sealed with a different treatment than laminate edges. You need to prepare the surface for sealing. Use an 80 grit sandpaper and remove all the dust that is formed. Use mineral oil, which offers protection for wooden countertop edges. Dip a soft sponge in mineral oil and apply a thin coat on the edges of your countertop. Reapply this solution once per week for maximum protection, as the oil can evaporate in time. Wax is a more durable sealant and may be applied in the form of a gel or oil. Apply a thin layer once per month or every two months. Both the oil and the wax are safe for kitchen surfaces where you prepare food. Given that the edges are less likely to come in contact with food, you may use non-toxic varnish, which will last for up to a year. Apply two coats of varnish, sanding lightly between coats, and allow the surface to dry before using the countertop.
