Can I Use A Sealant On The Laminate Flooring To Make It Waterproof?

A siliconized sealant can be used in the joints to protect from moisture seeping in between the planks, but the surface of the laminate cannot be sealed. Unlike hardwood, laminate contains a hardwood picture which is sealed with an aluminum oxide coating on the top of the laminate. Any sealant or wax will leave a residue on your laminate, which will collect dirt and will build up, making the cleaning process harder.
