How to Seal Laminate Countertops

Updated February 21, 2017

Laminate countertops come in a variety of styles and colours and are one of the most affordable countertop surfaces. Simple to maintain, and constructed from durable material, laminate is a cost-effective alternative to granite or marble. Although laminate does not require sealing, the process helps to shine the surface that may become dull over time. Certain gloss gel products help seal and shine your laminate countertops.

Mix 1 tsp mild dish detergent into a sink of warm water. Clean the laminate surfaces with a dishrag soaked in the soapy water. Rinse the dishrag with water and wipe the countertops to remove all solution. Dry the laminate surface with a clean cloth.

Apply 1 tbsp of gel gloss to a sponge, and wipe the gloss over a section of the laminate countertop, using circular motions. Add more gel gloss as needed to the sponge, working the sealant over the entire laminate surface.

Wipe the gel gloss from the laminate countertop with a clean cloth. Turn the cloth as you wipe the countertop to expose a clean cloth area. When finished, go back over the countertop once more to ensure you have removed all the sealant.


Seal laminate countertops when they become dull or cloudy.


Avoid using abrasive cleaners or tools on laminate countertops as they may scratch and damage the surface.
