Do you have a concrete floor that you love for its raw, natural look?
At District Design , we fully understand this desire to maintain the unique appearance of concrete while providing it with lasting protection.
Sealing or varnishing your concrete is essential to protect its surface from wear and stains and to minimize dust that can form over time.
In this article, we will introduce you to several products suitable for different experience levels and guide you through applying these sealers to your concrete surfaces.
Concrete sealing forms a protective barrier, reduces dust production, and helps maintain the natural beauty of your concrete floor or wall.
Why seal or varnish your concrete?
Concrete, while strong, remains a porous material. Without protection, it can absorb moisture and dust, and be prone to stains and abrasions.
Here are some reasons why it is crucial to seal or varnish your concrete:
-
Protection against stains and wear : Sealing prevents liquid absorption and protects against stains.
-
Dust reduction : Unsealed concrete naturally produces dust. A sealer reduces this.
-
Aesthetic improvement : Depending on the product chosen, the sealer can provide a matte, satin or glossy finish, enhancing the appearance of your concrete.

Concrete preparation
Before applying any sealer or varnish, it is crucial to properly prepare the concrete surface.
-
Clean thoroughly : Make sure the concrete floor or wall is clean and dry. Remove any dirt, dust, or oil residue. If your concrete has been sealed before, check it with the water test: if the water is absorbed quickly, the concrete is not sealed. If the water remains on the surface, the concrete is sealed.
-
Lightly sand : If necessary, roughen the concrete surface with a power sander and 120-grit sandpaper. This will allow the sealer or varnish to adhere better.
Product application technique
The technique for applying sealants or varnishes is similar for all the products mentioned. Here is a step-by-step guide for successful application:
-
Surface preparation : Sand the surface to remove any irregularities, then carefully vacuum up the dust.
-
Product Application : Apply your chosen product with a paint roller for large areas and a brush for edges and corners. It is essential to work in small sections to prevent the product from drying too quickly before you have finished spreading it evenly.
-
Work on a damp surface : When applying, ensure that the concrete surface is slightly damp to ensure optimal adhesion of the product.
-
Dry and repeat : Allow to dry according to the manufacturer's instructions. Typically, one to two additional coats may be required for maximum protection, respecting the drying times between coats.
Sealing concrete or brick walls
Sealants can also be used on vertical surfaces such as concrete or brick walls.
The method is similar to that used for floors, but some extra precautions are necessary to avoid drips.
-
Wall preparation : Clean the wall thoroughly and ensure it is dry before applying the product. If necessary, lightly sand the surface to promote better adhesion.
-
Even application : Apply the sealant with a roller or brush, taking care to cover the joints between the bricks or concrete blocks well.
-
Dry and apply additional coats : Allow the sealer or varnish to dry according to the instructions and apply one or more additional coats if necessary.
Differences between polished concrete and sealed concrete
When it comes to choosing between a polished concrete floor or a sealed concrete floor, there are several aspects to consider, including appearance, installation process, and maintenance.
-
Appearance :
-
Polished Floor : Polished concrete provides a smooth, glossy finish that highlights the natural texture of the concrete. However, it is not waterproof.
-
Sealed floor : Sealed concrete retains a more natural appearance, while providing waterproof protection with a choice of finish (matte, satin or glossy).
-
Installation process :
-
Polished Floor : Polishing concrete is a complex mechanical process that requires specialized tools and can be expensive.
-
Sealed Floor : Sealing is a simpler and more affordable process. It requires light roughening before applying the sealer.
-
Interview :
-
Polished floor : Less prone to stains but more slippery, polished concrete requires regular but simple maintenance.
-
Sealed floor : Easy to maintain, sealed concrete effectively protects against stains and wear, while being waterproof.
