Concrete sealers are highly beneficial for your concrete. They will make it more resistant to water, grease and oil stains, weather exposure and abrasion. Additionally, sealers can bring out the natural beauty of concrete and ensure easier maintenance. However, in order to provide all these benefits, you have to know how to properly apply the sealer and which tools to use.

Prepare the Surface

It is extremely important to properly prepare the surface before you apply the sealer. If there are any oil or grease stains, dirt or dust they might prevent the sealer from adhering properly. Additionally, if you already have a different brand of sealer applied, it is advised to remove it before applying a new coat. The two different sealers might not be compatible, so the experts recommend etching the surface first.

Choose Wisely

Before you even think about the application method, you need to find out which sealer best fits your needs. This way, it will be easier to apply it and provide a finish that will contribute to the overall design of your home. Also, keep in mind that each concrete sealer has different properties and you need to find the one that fits the needs of the surface on which you plan to apply it. So whether you want to cover your driveway, paving or a patio find the sealer that will do the job perfectly.

Smooth and Flat Surfaces

You should choose the applicator for the sealer according to the surface you will be applying it on. According to experts, lambswool applicators are the best way to apply the quality concrete sealer you have chosen. This tool is nothing more than a wooden block wrapped in wool, but it can apply the sealer easily and give it the smoothest finish, provided that the surface is smooth as well.

Spray the Sealers

Spraying is probably the easiest way to apply different types of sealers. This method is particularly good for water based ones, and the sprayer equipment is easy to handle. However, you will need some knowledge and experience in order to get the desired results. Additionally, make sure you clean the spraying equipment after using it to prevent clogging. The solution might harden in the sprayer, which leaves the equipment unusable.

Use the Roller

You can use the paint type rollers to apply the concrete sealer because it is effective and it can get better coverage. However, the downside of this method is working the rough surfaces in high temperature, since the solvent based sealers might not respond as well as you would like it. This method will also require applying multiple layers and some back rolling, but the end result will be smooth. If you choose this method, just make sure to avoid sealer pudding and blisters, because it may not set in properly, thus resulting in an unpleasant visual effect.

When to Apply

Another important aspect is the time of applying the concrete sealer. You should allow the new concrete to cure for at least 28 days before applying any sealers. Also, choose dry conditions to work under because if you apply sealer to damp concrete, haziness or improper adhesion might occur. Additionally, pay attention to outside temperature, which should typically be above 50°F. Lastly, make sure that the sealer is completely dried before you expose it to any foot and vehicle traffic.

Applying the concrete sealer is not an easy task to do. There are many different factors to consider before making a decision about application. Nevertheless, you should always rely on professional advice and find the method that suits your needs and the type of sealer and surface.
