Mitigate Efflorescence on Concrete by Applying a Concrete Sealer

Almost all buildings right now use concrete as part of their structural framework. Additionally, they incorporate concrete in constructing walkways, driveways, garage floors, and other indoor and outdoor areas of the properties.

Concrete is maximised in these areas as it can last for a long time. With proper upkeep and maintenance, concrete surfaces are expected to withstand heavy pedestrian and vehicle traffic. They can also resist heat, moisture, and other key elements in the surroundings. Concrete surfaces and structures are even eco-friendly as their core components are not toxic to the environment and can be recycled multiple times.

Some concrete surfaces, unfortunately, may be filled with patches of white and grey crystals, which can ruin their appearance as well as cause other issues to the properties.

The Formation of Efflorescence on Concrete

The existence of white and grey crystal patches is caused by efflorescence, which is the migration of white salt deposits on or near the concrete surfaces. Efflorescence often occurs on concrete surfaces like walls, floors, walkways, and driveways.

One primary cause of the efflorescence is the entry of moisture into the concrete surfaces and soaking the saturation. The possible sources of moisture entry include the existence of cracks in concrete surfaces and voids in concrete areas due to bad workmanship. Moisture can also enter the concrete surfaces due to the sudden leakage of soil, wastewater, or rainwater pipelines. Once the moisture evaporates, salt is expected to crystallize on the concrete surfaces, bombarding them with white streaks and grey patches.

Efflorescence can lead to various damages like decay and disintegration of concrete. It can make the surroundings unhygienic.

Other Causes of Efflorescence on Concrete

If you notice some streaks and patches on your concrete surfaces, you may have to mitigate and get rid of efflorescence.

Efflorescence on your concrete may happen not only due to the entry of moisture. It can also be caused by the existence of too high salt content on your concrete mix. Failure to cure your concrete properly can likewise lead to efflorescence. This concrete issue may also happen due to low atmospheric temperature during the concrete construction, too much water in your concrete can make your concrete surfaces porous.

Concrete Sealers Can Prevent Efflorescence

To deter and mitigate efflorescence on your concrete surfaces, you must purchase and apply a concrete sealant. A concrete sealer is a product applied to concrete surfaces to protect them from surface damage, staining, corrosion, and other similar types of damage. This product can effectively cover the pores in your concrete surfaces as well as prevent them from absorbing water, salts, and other damaging elements.

Before applying the concrete sealer, you must first rinse your concrete surfaces with a power washer. You can also clean them with a hose or spray bottle. Once dirty elements have been eliminated, you can now apply the concrete sealer according to its manufacturer’s instructions. Leave the sealer for a few hours until it becomes dry.

The last step that you must take is to rinse off your newly sealed concrete surfaces and wipe them with a dry rag to eliminate any moisture. To buy effective sealers for your concrete surfaces, you can contact us at Auseal.
