Thanks to its porous nature, keeping concrete free of stains from Algae, Mold and Mildew can feel overwhelming. It is essential to protect concrete from this growth as well as dirt and grime. Over time, the growth, and staining is not just unsightly, it's actually destroying your concrete. Follow these tips to keep your concrete clean and beautiful year round!
Whether removing algae off the walk or oil stains on the driveway, it is important to properly clean concrete about once per year. Stains that sit on concrete become harder to remove over time. Lichen, Moss, Mold and Algae are not only unattractive but can also make surfaces slippery and dangerous.
Not all cleaners do the same work. For example, the degreaser that pulls up oil stains from vehicles will not work against Algae, Mold, and Mildew stains, and vice versa.
If you are looking to remove efflorescence or the build-up of salts on the surface of the concrete, it is ideal to dry brush away the white, powdery substance. The introduction of cleaners or even water can cause more salts to rise to the surface.
When cleaning concrete, it is important to use enough cleaner to heavily saturate the surface. You may notice that concrete can look barely damp after just a few minutes. If this happens, apply more cleaner to get into the naturally occurring nooks and crannies.
For concrete that has a large amount of growth or has been neglected for several years, it may take more than one cleaning to return the original look of the concrete.
Whether cleaning organic growth or oily stains, concrete tends to look better the next day. This is because the water that has soaked into those nooks and crannies can result in a slightly darker look to the concrete. Once it has dried out, typically overnight, it will appear even lighter in color. This is especially true with older concrete.
Consider sealing your concrete surfaces after they have been properly cleaned. Be sure to research the best product and application for your job and to test it out before sealing the entire area. Consider:
While we may not think about it, we come into contact with concrete every day of our lives. Help to preserve your walks, drives, and even décor with these tips and your outdoor spaces will look great for years to come.
