Rubber spatula
Limestone sealant

Limestone filler

Refinishing a limestone tile countertop is an easy process which will bring the original look and appeal of the limestone back to its original state. Limestone is a very soft substance that takes a little extra care when working upon, and since it stains fairly easy, it has to be cleaned before it can be coated with a sealant.

Step 1 - Clean any Stains

Before even attempting to refinish a limestone tile countertop be sure that the surface is clean and that all of the stains are removed. Depending upon the type of limestone that you have, remove the stains by applying a paste made from flour, dishwashing soap, and water or flour, water, and hydrogen peroxide. Apply the paste over the top of the stain and cover it for 24 hours with a piece of plastic wrap. When taking it off, scrape it up with a rubber spatula, making sure that you do not scratch the surface. After all the stains are removed in this fashion, wash the entire countertop with a good quality limestone cleaner. Use a clean soft rag and very little pressure.

Step 2 - Apply Limestone Sealant Remover

Once again, depending upon the type of limestone that you have installed, apply the sealant remover and follow the directions upon the specific type that you are using. Be careful not to scratch the surface of the limestone. It is necessary to use a clean, soft rag when doing this, but be sure not to press down too hard upon the rag, and if you feel any particles of dirt between the rag and the limestone countertop, stop immediately and remove them before proceeding.

Step 3 - Apply Limestone Filler

If the countertop has a lot of swirls or scratches within it, or even some small chips or cracks, apply a thin coat of limestone filler in order to smooth the surface out. Once again follow the directions given for the specific product that you use. The filler should effectively fill in any minor scratches or chips, but if the countertop has some serious issues it would be a good idea to have it resurfaced before continuing onto the next step.

Step 4 - Apply the Limestone Sealer

Apply the limestone sealer, after the other chemicals have dried, with a soft brush. Apply the sealant in even coats, using a motion that covers one section at a time. Begin at the back of the counter, and brush forward in one even stroke, and then back up in a line next to it. Work as quickly as you can so that the sealant does not begin to dry as you apply the next row. This will ensure even coverage as well as preventing any lines from forming that will be seen after the sealant dries.
