Limestone has a natural look that is usually white but can be stained to other colours. Its surface can be cut in several directions, allowing blocks and walls without worrying about the way its patterns match, to be joined. Limestone can be free because it is a stone. On the other hand, the surface is porous, which might permit water to enter and harm the material. Implementing a sealer prevents moisture problems.
Eliminate any hardware that is attached to the wall using a screwdriver, as necessary. By using a stiff brush or broom clean any loose debris and dirt. For ground-in dirt or even soil that is serious, make use of a limestone cleaner. Select one that is biodegradable and has no harsh chemicals, especially if your wall is in the lawn being maybe penetrated by a garden using the cleaner.

Read the instructions on the sealant container to come up with the best application methods. Typically, you must stir the material and apply it within a certain temperature range that is at least 10 degrees Fahrenheit over freezing. Most sealants allow application by trapping masonry units in the liquid, or by brush, roller, pressure sprayer. A gallon of sealant covers from 150 to 200 square feet, although results vary by producer.
Wear goggles and protective clothing and operate in a well-ventilated area. If contacted by the sealer, wash skin immediately. Prior to reusing them, wash have been touched from the sealant.
Until it is totally saturated into the stone apply the first coat evenly across the wall as educated. 1 coat is okay, though two increases sealing performance. Apply the second coat has been consumed.
Allow the sealant to dry. Examine the wall by operating a hose on it or splashing water. The wall must repel the liquid.
