Sealing off concrete on any outdoor construction is necessary in order to protect the concrete from damage due to the various environmental factors, such as rain or snow, dust and sand, oil spillages on driveways and other such factors.

A concrete sealing extends the durability of the concrete structures such as driveways, patios, pool decks, etc. It not only extends the life of an outdoor construction, but also makes it easier to maintain and repair the concrete. Small cracks can be repaired just by adding another layer of concrete sealing.

Applying concrete sealing involves a number of steps and therefore there are a few things one should be taken care of while applying it.

 Choosing the type of sealant

There are primarily two types of sealant used in concrete sealing. They are the film forming type and the penetrating type. Film forming type of sealer is usually made from materials such as epoxies, which form a smooth coating on the surface of the concrete providing protection. The penetrating type on the other hand typically contains siloxanes, which penetrate into the deeper layers of the concrete to form an actual chemical barrier. They are the longest lasting variant and do not get peeled off from the surface.

Sealing outdoor concrete is different from sealing a concrete floor

An outdoor sealing of a concrete construction typically involves the use of a sealer in an analogous way to car wax on a car. They provide a protective coating. The characteristics of a good outdoor concrete sealant are:

1. It’s breathability

2. Resistant to damage from the UV rays of the sun

3. Resistant to being slippery, especially when wet.

On the other hand, concrete sealing is also a necessity for concrete floors such as in garages and basements. However, the characteristics required of an indoor sealant are as follows:

1. Preserving natural appearance while providing a protective function.

2. Prevent accumulation of stains and scuff marks

3. Making sure no moisture related problems become relevant.

Depending on the requirement the type of sealant is selected for outdoor and indoor applications. Mostly the outdoor constructions go with a penetrating type of concrete sealer; whereas the indoor floors go with a film forming type of sealer.

New concrete and old concrete sealing

It is best to apply to seal on a concrete construction after it has settled for a minimum of 28 days. To seal a brand-new applied concrete, it is prudent to use sealers that come with a curing substance added. For old concretes, concrete sealing can increase the strength of the structure and gives it a brand-new look.

Change in appearance after sealing

Concrete sealing can provide a natural coloring effect to the concrete, depending on the sealer type used. While the aesthetic part is not the most important aspect of a sealant it can still add color and a glossy finish in some cases.

1. Color: some sealers come with a natural tint of color which provides the concrete with a colored finish upon application.

2. Finish: a concrete sealer can provide a glossy or matte finish to the concrete depending on the sealant type.

Concrete sealing of countertops

Concrete countertops have now come into prominence due to their durability, and thereby require concrete sealing as well. The main focus for the sealant is to be waterproof and protective at the same time. Being food safe is also an important characteristic they should have while having no harmful emissions. The sealant type used can cause the final appearance to range from a matte finish to a highly glossy finish depending on the customer’s preferences.

 Concrete Sealing

Concrete sealing is a must for any concrete construction, whether outside or inside. It enhances the lifespan of the product while at the same time giving it a better finish and final appearance.
