How to Refinish a Limestone Floor
Though limestone floors are well known for their high durability, they will eventually need refinishing after a certain period of time. In areas of the floor which receive a great deal of traffic, the tiles can eventually become discolored and grouting between the tiles can start to wear, causing irreparable damage. Every five years or so, a limestone floor should be refinished to ensure that it retains its high durability and attractive look. Refinishing a limestone floor is something that requires a few special materials as it is something that standard cleaning materials can no longer remedy.
Step 1 – Make Preparations
First, purchase an appropriate acid-based floor cleaner. Make sure you purchase enough to cover the entire floor area. You should ideally refinish the entire floor so this means removing all furniture from the room. If there is any furniture that cannot be moved, such as built in units, you will need to make sure that these are properly covered before beginning. The chemical cleaners that you will be using can cause severe damage to the surface of many furniture items.
Step 2 – Apply the Floor Cleaner
Work systematically from one side of the room to the other. Apply the acid cleaner to the floor, covering the tiles thoroughly. You should use rubber gloves before you handle any cleaning products. Ensure that the floor cleaner evenly covers the entire floor. Use a scrubbing brush on the areas which have a great deal of dirt on them. The grouting lines should also be thoroughly cleaned. Wash the floor with water, changing the water often. Leave the floor until it is completely dry.
Step 3 – Apply the Stone Sealer
Depending on the type of stone sealer that you purchase, you may either have to apply it once and allow the tiles to absorb it or you may need to apply it in multiple layers. Refer to the instructions on the packaging. Using a specially designed applicator pad to apply the sealer is by far the most convenient method. You can use a cloth or sponge. Work in one small section at a time, pouring small amounts of the sealant and spreading it evenly around the surface. Cover both the tiles and the grout joints thoroughly, spreading the sealant in a circular manner.
Step 4 – Finishing the Job
The floor should be left to dry overnight before walking on it or moving any of the furniture back into the room. When you are satisfied that the floor is completely dry, you can then move any rugs and furniture back into the room. You can continue after this using standard floor cleaning methods. The surface should not need to be refinished for another five years.
