In order to protect concrete from damage caused by spills of brake fluid, gasoline, and engine oil, all of which are absorbed by concrete, on the one hand, and to have a suitable aesthetic in the parking space on the other hand, epoxy and polyurethane flooring are used in the form of pouring.

These coatings cannot be applied to troweled concrete, and it is necessary to first trowel the concrete or smooth it with self-leveling cement, and then apply epoxy or polyurethane on it.

Number of layers: In general, the flooring layers include primer, intermediate, and final. In polyurethane flooring, due to its higher abrasion resistance than epoxy and the lack of stress transfer, small cracks from the concrete surface to the final layer do not transfer. Find out.

Comparison of properties of epoxy and polyurethane flooring:

• Epoxy flooring is a branch of rigid polymers, but polyurethane flooring is a branch of flexible polymers, and due to this property, small cracks in concrete (craze) do not transfer to the surface of polyurethane flooring.
• Epoxy flooring has a very high resistance to chemicals and solvents compared to polyurethane flooring.
• Polyurethane flooring has a higher light resistance compared to epoxy flooring.
• Polyurethane flooring in comparison Epoxy flooring has higher abrasion resistance.
• Epoxy flooring has higher adhesion to concrete surfaces compared to polyurethane flooring.
• Polyurethane flooring is more sensitive to concrete floor moisture and air humidity compared to epoxy flooring.

Therefore, in cases where the contractor and operator want to use the benefits of polyurethane and epoxy together, this company recommends using epoxy materials as a primer and middle layer and using polyurethane flooring as the final layer. Because the final layer is directly exposed to abrasion and also withstands stresses.

The Arg (Amir Kabir) Tajrish project with an area of ​​40,000 square meters was implemented by this company using this method and is approved by most employers.

Implementation stages:

• Enclosing the desired area to prevent personnel from moving
• Scraping the concrete surface using a Scratch device or other device
• Emptying the grout joints using a suitable device
• Vacuuming all surfaces using a vacuum device
• text-align: justify;">Apply a primer coat (sealer coat) to all surfaces
• Filling expansion joints using special epoxy grout
• Applying an intermediate layer of epoxy floor coating using a squeegee
• Applying a final layer of solvent-free self-leveling epoxy (Solvent free epoxy) or roller
• Debubbling the surfaces using an airless roller
• Final inspection of epoxy surfaces
