Concrete sealer gives an extra layer of protection to your concrete floors both indoors and outdoors. It safeguards the concrete floors from damage due to continuous weather changes.
Sealing also prevents concrete from staining and discoloration. It adds beauty to your floors and improves the overall appearance of your home. Have a look at excellent concrete sealing products at http://www.bestbar.com.au/product/concrete-sealing/.
In order to get complete benefits from concrete sealers, they have to be applied properly. According to decorsnob.com, each step of concrete sealing affects the final result. Following are some points which you have to take care of while applying concrete sealers.
Prepare the surface properly
The surface of the concrete has to be cleaned thoroughly. Any oily or greasy substances, dust, stains, etc must be completely removed for proper adherence of sealers. If you are reapplying the sealer one or two years after the first application, then you may have to remove the previously used sealer from the surface. This is advised by manufacturers especially if you are choosing a different brand for reapplication, the reason being the incompatibility of different products.
Some manufacturers go one step ahead and recommend using an etching solution to clean concrete. They say that this ensures the best adhesion.
Select the right tool
Using the right tool for applying concrete sealer is very important. Right tools ensure the best coverage and proper sealer thickness required for maximum performance. Rollers and sprayers are the most commonly used tools. Among sprayers, there are further categories such as airless sprayers, low-pressure sprayers etc. T-bars, Microfiber applicators etc are some of the not so common tools.
Choosing a tool mainly depends on whether the sealer is solvent-based or water-based. Each brand of sealer will have specific application guidelines provided by the manufacturer. Make sure you consider those instructions.
Whichever tool you are using, your focus should be on maximum coverage. The coverage rate varies based on the porosity of the concrete. The thinner the layer is, the better. Applying two thin coats is the best. Apply the second coat in a perpendicular direction to the first. This ensures even coverage. Make sure not to form bumpy thick areas of sealer in between.
The second coat should not be applied immediately after the first. You should wait for a certain time as recommended by the manufacturers.
Best time to apply sealer
Concrete has to be cured properly before applying the sealer. Generally curing requires 28 days. The concrete has to dry up completely after curing as most sealers should be applied to dry surface. Applying sealer to concrete which is moist may lead to lesser adhesion.
Temperature also plays a role while applying sealers. 50 degree Fahrenheit or above is the desirable temperature during and at least 24 hours after applying the sealer. Give the sealer enough time to dry up before walking or driving on the surface.
These are some general instructions for applying concrete sealers. Apart from this, there may be some specific instructions from the manufacturer depending on the brands. Follow those instructions as well for successful application.
