Laminate slate flooring is made of sturdy synthetic material that has an elegant appearance and is easy to maintain. However, scratches and cracks may appear on the surface of the flooring, and these can be fixed using repair putty or wax crayons.

Step 1 - Clean the Floor

Remove the dirt and dust from the laminate slate flooring using a vacuum cleaner or a broom. Mop the flooring with a solution that contains one cup of dish detergent and three gallons of water. Alternatively, use half a cup of vinegar in three gallons of water. Rinse the floor and wait for it to dry.

Step 2 - Identify the Cracks

Check your laminate slate flooring and identify all cracks and chips. Even the superficial chips should be repaired to prevent additional damage. Mark the areas that need repair. Establish what color of putty you need to purchase. Certain scratches may not need putty and may be repaired with a special wax crayon. Make sure the crayon has a shade that is similar to the color of the flooring.

Step 3 - Sand the Area

Sand the inside of the cracks to make the area smoother and remove any dirt that has accumulated. This will make sure the putty will bond well with the flooring. Remove the dust with a moist sponge.

Step 4 - Prepare the Putty

Purchase the putty from a hardware store. Make sure the color you choose is similar to your flooring. Use the available swatch books to find a color that is closest to your laminate slate flooring. Prepare the putty by mixing it with the hardener that is provided in the kit you buy. Use a plastic scraper or a putty knife when mixing, and make sure the putty is homogeneously mixed with the hardener.

Step 5 - Apply the Putty

The putty hardens quickly, so you only have a few minutes to apply it. Fill the cracks in your laminate flooring using a putty knife. If your cracks are smaller, use a smaller putty knife, which will allow you to control the amount of putty you apply and avoid putting an excess of filler. Apply several thin layers of filler rather than a large amount of putty at once.

Step 6 - Remove Excess Putty

Remove the excess of putty by employing a damp piece of cloth, but do this before the putty hardens. If the putty is already dry, remove the excess with a putty knife or a razor blade. Use the razor blade with caution to avoid scratching the laminate surface.

Step 7 - Allow to Dry

The putty hardens within minutes, but allow two to three hours for the filler to dry completely before you step on the repaired floor.
