Sealing slate tile flooring is an easy DIY project. To get you started, you only need the right tools and a pair of handy hands, to prepare the surface and apply the sealer with a paintbrush. Here are the steps.

Step 1 – Clean the Surface

Clear the area. Move the furniture, and remove the rugs or mats from the floor. Sweep or vacuum the floor, to remove dirt and other debris.

Next, create soapy water with detergent and water. Get the mop, and wipe the floor with soapy water. Get a bucketful of clean water, dip a clean mop, and wipe-rinse the floor.

If you want to treat the floor for molds, mildews and other living organisms, you may mop the floor with oxygen bleach solution. This step is optional. To make a solution, mix oxygen bleach with water in ratio of 50:50.

If your slate tile flooring is in the dining or kitchen area, use of degreaser is an option to remove oil and grease on the surface. This will ensure that the sealer that will be applied later will not slide off.

Step 2 – Strip and Neutralize

Old sealer from the slate tile flooring should be removed as well. This can be done with the use of a paint stripper. Select eco-friendly friendly strippers, that contain natural and mild ingredients. An example is a soy-based stripper that can be used for natural stones, such as slate.

Apply stripper on the area using a paintbrush or roller. Refer to the manufacturer’s instructions on how to apply the compound, and the waiting time before rinsing. Use a stiff nylon brush to remove old paint or sealer on the surface. Vacuum the floor to remove debris.

After chemical stripping, the slate tiles has to be neutralized, to prevent oxidation and the tiles to becoming brittle. Mop the neutralizer on the floor and rinse. Follow the instruction on the package for the correct usage of neutralizer. As a rinse, use distilled water. Tap water contains minerals that can cause discoloration and oxidation on the slate’s surface. Allow the surface to dry completely

Step 3 – Check for Damage and other Possible Repairs

Inspect the tiles for cracks, holes and broken tiles. Use epoxy glue to repair cracks and holes. Remove and replace broken tiles.

Step 4 – Apply the Sealer

Get the paintbrush or roller and dip it in the sealer. Apply the sealer in 1 direction only, starting with a very thin coat. Let it stay for 10 minutes or more, depending on the instructions, and then thinly apply second and third coat. After several coats, allow the area to dry for more than 24 hours, before resuming heavy traffic on the area.
