Understanding Concrete Sealing

Most structures utilise concrete during construction. If you look at a concrete surface's finished state, it appears aesthetically appealing because of the finish that is applied. Part of this finish is a sealant that helps the concrete surface last for the longest time possible and also helps retain the structure's aesthetic appearance.

Over time and due to harsh environmental conditions, concrete can get damaged and start to crack or crumble. This can cause stability problems and unsightly structures. The concrete needs to be restored; part of this process includes the application of concrete sealing. Here's what you need to know about concrete sealing:

What Is Concrete Sealing?

It is the application of either acrylic, epoxy, urethane, polyaspartic or silicate to concrete to strengthen and protect it from harsh weather conditions and traffic damage. The different sealants mentioned above have different uses; for example, acrylics may be used for decoration and protection, silicates are used to increase the density and strength of concrete and epoxy and urethane can be used on concrete surfaces that may be exposed to chemicals or high traffic.

When Should Concrete Be Sealed?

There are two instances when concrete surfaces should be sealed:

When it is poured for the first time during construction 

You have to wait for it to cure and dry before applying any sealant. Moist conditions can render the sealant ineffective.

When the concrete surface is damaged

This involves several steps that have to be followed for the sealant to be effective. First, you have to clean the concrete surface well to remove any debris that could make an analysis of the condition of the concrete surface difficult.

Secondly, inspect the concrete surface to find out whether a sealant had been applied initially or not. If it had, you need to remove it before applying a new sealant. You might also need to remove any paint, stains, grease or oils on the concrete surface.

Thirdly, clean off the surface and inspect it once more. If there are any cracks, fill them up before applying the sealant.

Fourthly, wait until the floor is dry and then apply the concrete sealant that best meets the needs of your concrete surface.

From the above, you can tell that concrete sealing should be done by a qualified concrete sealing specialist. DIY attempts might lead to further damage or shoddy work that needs redoing. You will not only have wasted time and energy but your hard-earned money as well.
