How to Clean and Seal Concrete

Concrete is a popular building material, but it can be susceptible to damage from weathering, staining and general wear and tear. By cleaning and sealing your concrete surface, you can help to protect it from these damaging elements and keep it looking new for longer.

What is concrete and what are its benefits ?

Concrete is a mixture of cement, water, sand and gravel. It is widely used as a building material due to its durability and strength. However, concrete can be susceptible to damage from weathering, staining and general wear and tear. By cleaning and sealing your concrete surface, you can help to protect it from these damaging elements.

How to clean concrete

To clean concrete, you will need a pressure washer, a stiff brush and a cleaning solution. Pressure washing is the most effective way to clean concrete, as it will remove any built-up dirt or debris. You can either use a commercial cleaning solution or make your own by mixing one part bleach with four parts water. Once you have mixed your solution, wet the concrete with a garden hose and then apply the cleaning solution with a pressure washer. Start at the top of the surface and work your way down, using a back and forth motion. Rinse the area with clean water once you have finished washing it.

How to seal concrete

There are two types of sealer that you can use on concrete – a topical sealer and a penetrating sealer. Topical sealers provide a barrier on the surface of the concrete, which protects it from staining and weathering. Penetrating sealers penetrate into the concrete, providing protection from within. Both types of sealer will need to be reapplied on a regular basis, so it is important to choose a sealer that is suitable for your needs.

If you are sealing concrete that will be exposed to weathering, such as a patio or driveway, then a topical sealer would be the best option. If you are sealing interior concrete, such as in a basement, then a penetrating sealer would be more suitable.

To apply a topical sealer, you will need a paint roller or brush. Start at the top of the surface and work your way down, using even strokes. Make sure that you cover the entire surface and pay attention to any cracks or crevices. Once you have finished applying the sealer, leave it to dry for the time specified by the manufacturer.

To apply a penetrating sealer, you will need a pump sprayer. Start at the bottom of the surface and work your way up, spraying the sealer in a back and forth motion. Make sure that you cover the entire surface and pay attention to any cracks or crevices. Once you have finished applying the sealer, leave it to dry for the time specified by the manufacturer.
