Concrete pavers look great when they are first laid and stay that way for a long period of time. They will start to look worn down, however, if they have been there for a long time. This is generally due to the weather. If the concrete is porous, water absorbs into it and you could have mold buildup. Fortunately, there are some things you can do to bring your concrete pavers back to life again, two of which are listed below.
Clean and Seal the Concrete Pavers
Clean the surface of the pavers. If you do not see any kind of mold or algae growth, scrub away dirt and grime with a stiff broom. You can then use a power washer with a mild detergent to clean them.
If you see mold growing on the concrete pavers, purchase some oxygen bleach liquid. Fill a bucket with half water half bleach, and then pour it onto the pavers. Make sure you cover the entire surfaces. Let the bleach sit for about 10 minutes. Keep an eye on it, as you do not want to let the bleach dry. If you are doing this on a very sunny day, the bleach will dry out much faster so wait until it is overcast.
After the 10 minutes, use the stiff broom to scrub the surface. When you are finished, rinse the pavers thoroughly to remove the bleach. If you still see mold, repeat this process until it is gone.
You can then put a sealant on the concrete to offer it some protection against the weather elements. Purchase sealant at a home improvement store, and follow the directions on how to apply it.
Stain the Concrete Pavers
Staining the pavers is another way you can bring them back to life. You can find stain at home improvement stores, and you will find that there are many different colors you can choose from.
Before you stain, you will need to etch the surface of the concrete, as there has to be some texture. To do this, purchase some etching acid at the home improvement store. It is painted onto the stones with a traditional paint brush. Once you are finished, wait approximately 30 minutes to give the acid time to eat away at the surface causing it to be textured.
Use a garden hose to thoroughly rinse the etching acid off the stones. You are now ready to apply the stain. This is also brushed onto the concrete with a paint brush. The stain you purchase will come with complete instructions.
If your concrete pavers still do not look like the way you want them to, contact a paving contractor (like First Water Contracting LLC ) in your area to replace them for you.
