Most concrete surfaces will last a very long time when they are properly maintained. Maintaining a concrete surface is no different than other surfaces, it just needs to be cleaned periodically and protected from the elements. Harsh weather and climate can take their toll on concrete that is not waterproofed. When water and moisture are able to penetrate the concrete, it can cause all types of problems. Most notably, constant moisture can create mold, mildew, and algae buildup. This can break down the concrete over time and is extremely unsightly. It can also create a slippery when wet surface, which can be dangerous.

In climates that see below-freezing weather in the Winter, freeze and thaw damage is very common. When moisture penetrates the concrete and freezes, it expands. This can cause chipping, cracking, and heaving of the concrete, literally breaking it up and ruining the structure. Repairing this type of damage can be costly. The good news is that it is avoidable with some regular maintenance. The best protection you can give any type of concrete surface is to waterproof it so water and moisture cannot penetrate the surface.

To waterproof concrete, it needs to be clean and free of any contaminants that may hinder the performance of the waterproofing sealer. This can be accomplished with a pressure washer and some concrete cleaner. Concrete should be cleaned in this manner anywhere from yearly to bi-yearly depending on the area. In addition to cleaning, you should apply a waterproof sealer every couple of years. Knowing how to waterproof concrete is not difficult. By simply following the directions on the label you can waterproof concrete with a brush, roller, or garden-type sprayer.

Multiple coats may be necessary depending on your situation and the type of waterproof sealer you are applying. Be careful not to over-apply the sealer as this can lead to other types of issues. Always pay attention to the weather and as mentioned follow the manufacturer’s recommended suggestions for application purposes. Knowing how to waterproof concrete can be a huge advantage in protecting your investment. When maintained properly, your concrete surfaces will serve you well for many years to come.

how do I remove existing sealer from concrete pavers? I used a Valspar product on my patio, applying it per product application directions and am not happy with the results. the product is not breathable, holds water, did not stabilize the polymer sand in the joints (the patio is tumble stone concrete pavers) and made the surface slippery.
