High-quality and durable concrete floor sealing

Concrete floors should be thoroughly and evenly sealed to increase their resilience and durability. The concrete floor sealer from Mainbrick is ideal for this. Special paint is available for this purpose, which provides a durable, weatherproof and abrasion-resistant coating. A professional sealer acts like a protective film that keeps dirt, dust and liquids out and prevents them from seeping into the concrete. There is a wide range of products available for concrete sealing, which differ not only in terms of color and price. Depending on the content and components, they are suitable for indoor or outdoor use. In addition to the all-round sealing of floors, some products can also be used to seal other concrete parts. Below you will find out which product is best suited for sealing concrete floors and how the lacquer and epoxy resin products are applied.

Why should you seal concrete floors?

Concrete is a robust and durable material. Nevertheless, the floor can show signs of wear, unevenness and cracks after some time. Water and other liquids can penetrate these areas. This increases the damage and the floor or concrete floor becomes leaky. To maintain the quality of concrete floors, they should be treated with a concrete sealer made of epoxy resin. An epoxy resin-based product forms an effective protective layer, improves the appearance and increases the service life of the floor. The surface can be made even and uniform. This also makes cleaning easier. Dust and dirt cannot settle so easily in cracks and pores in the concrete.

Soil sealing indoors and outdoors

Concrete floor sealing for all concrete surfaces

A sealer for concrete floors is recommended for both indoor and outdoor areas. Suitable products can be found for basements and garages, for example. In addition to the protective function, floor sealing also achieves a visual effect. The sealed floors convey an elegant and homely impression. Cracks, unevenness and stains can be reliably avoided. Especially in workshops and garages where paint and oils are used, it is important to be able to clean the floor quickly and easily. With sealed floors, the substances remain on the surface and do not penetrate the concrete layer. This makes it easier to remove stains and keep the color of the concrete floor even. Weatherproof products made of acrylic resin are recommended for outdoor use. They are ideal for sealing plinths, concrete floors, kerbs and facades. A hardener is added to every product for outdoor use, which makes the floor sealers particularly robust and abrasion-resistant. When buying, you should make sure that the sealant is waterproof and weatherproof. The coating should be able to withstand large temperature fluctuations and frost without any problems. Concrete sealers for indoor and outdoor use are available in many different colors. This allows the design of the floor to be perfectly coordinated with the surroundings.

How are concrete sealants applied?

If you need a tip for floor sealing, you will find some useful tips on application here. The contents of most sealing products can be applied directly to the substrate. To avoid unevenness and color deviations, the concrete floor can be primed with a deep primer. The deep penetrating primer forms a closed and hardened surface on concrete and screed surfaces. After drying and hardening, this can be painted with a sealing product made of lacquer or epoxy resin. Pre-treatment is particularly recommended for colored concrete sealers, as this allows the colors to stand out better. For a neutral design, you can choose a product that is colorless. Outdoor floors can also be perfectly primed with outdoor sealers, including walls, paved paths, steps and kerbs. The sealers are easy to apply, harden quickly and have a low odor. Especially in the workshop or garage, floors should be protected from dripping engine oil, petrol and other liquids. A floor coating can also prevent unsightly marks from tires or road salt from attacking the surface.

The floor coatings for workshops and garages are abrasion and chemical resistant. Before applying the floor sealant, the garage floor should first be thoroughly cleaned. Sand and dust residues should be removed with a vacuum cleaner. Unsightly marks can be removed with suitable cleaning agents and stain removers. Finally, wipe the concrete floor with a damp cloth. Once dry, the garage floor can be primed. This is particularly necessary if the substrate is absorbent. To do this, mix the primer thoroughly and spread evenly with a microfiber paint roller. To achieve a harmonious overall appearance, the individual strips should overlap slightly. The primer must dry for 12 to 48 hours before the garage floor can be sealed. During the priming process, it is essential to pay attention to the ideal application temperature, which is between 15 and 25 degrees. Particularly in summer, there are large temperature differences between the warm and humid air and the cool cellar or garage floor. This can cause stains and condensation. Once the primer has dried and hardened, the actual floor sealant can be applied. To do this, the sealing liquid is mixed with its components according to the manufacturer’s instructions. Starting in one corner, the contents are poured onto the concrete in small sections.

This is then immediately spread evenly with a microfiber roller lane by lane. This makes it easy to apply the Mainbrick concrete sealer. Modern sealing liquids contain self-leveling layers that distribute themselves and automatically level out minor unevenness. To achieve an even texture, the concrete floor should be sealed in one step. You should therefore calculate exactly how many liters or kilograms of sealing liquid are required beforehand. To avoid a glossy film and to achieve an even texture, the sealing process can be repeated after drying. Finally, allow the sealed surface to harden for 24 hours. Garage floors should be left to cure for at least a week before they can be driven on. Under normal use, the concrete sealant lasts for several years and offers reliable protection against road salt, dirt, engine oil and moisture. This floor sealer is also an excellent addition to the paving joint mortar water-permeable for concrete sealing and natural stone.

Sealing products for immediate use

A tip for DIY enthusiasts is to use sealing products immediately. They do not need to be diluted with water. Instead, they can be applied immediately, which makes work easier and quicker. The various components combine ideally to create a reliable protective effect. Modern Beton-Sigel products are not only waterproof, but also resistant to heating oil. They can therefore also be used to prime boiler rooms and heating oil tanks. The concrete sealers are available in different colors and also colorless. Concrete gray, pebble gray, white and gray beige are the most frequently chosen color variants. For larger areas such as garage and industrial floors, there are storage containers with a capacity of one liter or several kilograms. With the water-dilutable products, several kilograms of sealant can be obtained.

A suitable product can be found quickly for every area of application. When buying floor sealant, you should not only pay attention to the content in liters, but also to the weight in kilograms. This tells you how economical the product is. Basements, stairs, heating oil pans as well as garage and industrial floors can be sealed and colored with sealing products at a reasonable price. When buying sealing liquids, always look for quality seals. Tested products are less harmful to health and the environment and are easier to apply thanks to special components. You can also use concrete impregnation, but this is more suitable for screed and is specially designed for this.
