A floor coating is a special covering applied to existing floors such as concrete, screed, or tiles to protect, beautify, or improve the functional properties of the surface. It usually consists of resin-based materials such as epoxy resin, polyurethane, or acrylic, and may also contain additives such as quartz sand, gravel, or color pigments.

The substrate must be level and free of cracks and have a rough surface, which can be achieved by grinding with a diamond grinding cup or by shot blasting.

A standard floor coating is structured as follows:

1. Primer

2. Coating (flow coating or roller coating)

3. Optional sealing with anti-slip properties

If the current substrate is not yet primed, a primer is required as the first layer.

There are different types, which vary in material, function and area of ​​application:

• Epoxy resin coatings (EP) – highly durable, chemical-resistant, ideal for industry, garage or workshop.
  
• Polyurethane (PU) coatings – flexible, UV-resistant, good for indoor and outdoor surfaces.
  
• Acrylic coatings – thin top layers, more decorative, weather-resistant.

Standard coatings are often smooth, so the surface should be modified if necessary to ensure safe walking or driving on.

Slip resistance can be achieved by adding quartz sand or special anti-slip agents.

Our complete floor coating kit offers a perfectly coordinated coating system from SIKA. It contains the correct amount of primer and the self-leveling coating in the desired RAL color for your coating project.

The lifespan depends heavily on the material, substrate, and load:

Epoxy resin (interior use, garage): approx. 10–20 years

Polyurethane (UV-resistant, outdoor use): approx. 15–25 years

Stone carpet (terraces/balconies): approx. 15–25 years

Crucial for the lifespan are careful substrate preparation, the correct layer thickness, the stress from use and UV exposure outdoors.

Floor coatings offer numerous advantages over conventional floor coverings such as tiles.

Because they are applied seamlessly, there are no joints where dirt or water can accumulate, which makes cleaning significantly easier. They are particularly durable and resistant to abrasion, chemicals, and mechanical stress.

Furthermore, floor coatings can be designed in many colors, textures and gloss levels, making them both functional and decorative.

They can be used flexibly on uneven surfaces, can easily be made slip-resistant and require little maintenance, making them practical and cost-efficient in the long term.

Floor coatings are versatile:

The most common projects are garages, basements, workshops, industrial areas, warehouses and parking garages.

RAL colors are standardized colors developed to clearly define and reproduce colors. They are primarily used in industry, crafts, painting, and construction.
