How to Repair a Limestone Countertop
Limestone countertop, unlike granite or other stone counters, requires specific cleaning techniques. If the stains from spill are not cleaned immediately, the stain seeps through the surface leaving permanent etched marks. As a result, only cautious care of the countertop guarantees long durable look of limestone. You can repair and clean your limestone countertop very easily yourself by following the below steps.
Step 1: Clean the Countertop
Remove all the equipment from the countertop to prepare it for repair. Soak the sponge in water and rub it across the surface to clean the top from any dirt. Use the dry piece of cloth to dry the surface. The marks on the limestone will appear more conspicuous therefore, identify the stains and their nature. Stains caused by different sources require different techniques for repair.
Step 2: Rub the Surface with Sandpaper
Stains will form etched marks on the surface which you will be able to feel from your hands as well. Fold a page of normal sandpaper into fours and rub it across the marks. Apply even and gentle pressure, while switching sides of the sandpaper systematically as limestone sticks to the paper. Make sure you do not use sand paper unevenly because it will result in an uneven surface and will affect the beautiful finish of limestone. When the stain fades, soak the sponge and rub it across the surface again. Use a dry piece of cloth to dry the surface.
Step 3: Apply Paste
After the stain marks have been faded, apply paste on it to restore the top to its original look. For beverage stains, make a paste by mixing a cup of flour in 2 tbsp ammonia and water. Similarly, for more oily stains, use hydrogen peroxide instead of ammonia to achieve professional results. In the event of failure to obtain these materials, choose from a variety of stain solvers available in the market. Apply the paste evenly on the surface of the marks and allow drying. Use plastic cover to wrap the surface and leave the mixture untouched for at least 12 hours.
Step 4: Remove the Paste
Paste, allowed to sit on its own, will harden over time as it will disintegrate the compounds comprised in the food and liquid stains. Use a spatula to scratch off the hardened paste cautiously. Make sure you do not scratch the surface of the countertop through aggressive movements.
Step 5: Clean the Surface
Dampen the sponge in water and clean the surface of the countertop with it. Make sure the sponge is not soaking. Use a dry piece of cloth to dry the surface. Make rigorous circular movements till the shine of the surface is restored. Keep a cloth at an easy access area to allow you to clean the spill stains immediately without allowing for the stain marks to settle. You should constantly and periodically clean the limestone countertop to avoid any repair work later on.
