Laminate flooring is generally much more durable and scratch-resistant than wood and can be maintained with a minimal amount of fuss. Laminate is frequently used in kitchens for this reason since the floors in those rooms generally get exposed to much more wear and tear from grease and dirt. Laminate flooring can be coated with a protective sealer to help maintain it for a longer period of time. Applying a protective sealer to a laminate floor can be done fairly simply with a little bit of work.
Remove any furniture or other items from the floor so you can apply sealant evenly.
Mop the floor with a mixture of warm water and mild detergent to remove any dust and dirt prior to applying sealant. The mop should just be slightly damp and not soaked to prevent water from soaking into the seams of the laminate.
Dry the floor with a soft rag to further remove dust. The floor needs to be completely dry before continuing.
Apply a laminate sealer to the floor using a mop. You can use a water-based sealer that will last several months or a polyurethane sealer that lasts longer but may darken lighter floor coverings. Start in the far corner of the room and work toward the door so you don't get stuck in a corner.
Apply a second coat once the floor has dried. Several coats help make the sealer last longer and provide better protection to the floor.
