Concrete is one of the most popular construction materials in the world. It is affordable, versatile and structurally sound for buildings of all kinds. Usually, concrete's finish is robust enough to withstand various tensional and abrasive forces. However, you can go a step further and improve the lifetime of your concrete surfaces by sealing them. The seal beads water on the surface of the concrete, preventing it from seeping into the heart of the structure. The seals also improve the concrete's look and fight staining by creating a protective layer between the concrete and the spills. The following piece offers a detailed discussion for anyone who wants in-depth knowledge of concrete sealing.

Preparing the Concrete Surface

When you take on a concrete sealing project, note that the initial stages are critical for your success. The first step is ensuring that the concrete surface is clean. It should be free of any materials that will hinder a strong bond with the sealant. Clean the concrete with suitable brushes to remove grease, stains, dust and dirt. Moreover, ensure that you remove traces of other sealants so that you do not apply your new sealant on top of another used brand.

Take Note of the Number of Coats

The number of coats you apply plays a significant role in the quality of protection on your concrete surface. Usually, two thin coats are ideal for dependable coating. Doing more than two puts you at risk of having a concrete sealer with puddles and uneven, thick sections. During application, the second layer of sealant should be perpendicular or in the opposite direction to the first layer. The application interval should be in line with the manufacturer's recommendations.

Dealing with Concrete Joints

Concrete joints are intersections of two or more concrete panels. They break the continuous flow of the concrete surface, which can easily turn them into lines of weakness for concrete sealants. It may not be mandatory to seal concrete joints. However, doing so eliminates the chances of any ingress and damage by harmful elements.  

First, you should only apply a sealant to a joint after allowing it to shrink and relax as much as possible. Allow the joint to heal through different times of the day and night to take advantage of significant temperature changes. The fluctuations allow the slabs to shrink and relax, settling in a more predictable position that suits your sealant. Secondly, you can make the most of your sealant by introducing backer rods to keep the sealer plugs thinner and ideal for application in the joints.
