  1. Start with cleaning the algae buildup that sometimes forms around eaves and chimneys. Spray a moss cleaner on the affected areas and let it remain so for 48 hours. Once the moss or the algae trunks are bright red, start the removal process to prepare the base for limewash.
  2. Wash the entire surface with water so that the surface is free of moss cleaner and other dirt that settles on the house over a period of time. Touch up corners and crevices with some lime wash using a small masonry brush.
  3. Wait for another week, and then apply a fresh coat of mineral shield as an invisible topcoat. This will reduce weathering, repel water, and elongate the life of lime paint by offering protection against grass, clay, and dirt. By giving it enough time to dry, you will be able to prevent moisture-related issues.
  4. Stain Removal is of utmost importance. Therefore, for a quick fix, make a paste by mixing baking soda with water. Apply the paste on the stained wall and allow it to sit for a few minutes so that it reacts with limewash. Once it has dried, take a brush and scrub the paste off the wall gently with a brush. Rinse the space with water to finish the process.
  5. If you have a small surface like a fireplace with a limewash brick exterior, you can clean the surface thoroughly so that it lasts longer. Make a mild cleaning solution by mixing water with a small amount of pH-neutral soap. Perform a small patch test before using the entire mixture on the complete surface.
