The Common Mistakes In PU Flooring Application And How To Avoid Them

Polyurethane (PU) flooring is a durable and versatile solution for industrial and commercial spaces. However, improper installation can lead to a variety of issues, including premature wear, cracking, and delamination. To ensure a successful PU flooring project, it's crucial to avoid these common mistakes:

PU (polyurethane) application

1. Inadequate Surface Preparation:

Problem: A poorly prepared surface can compromise the adhesion of the PU coating.

Solution: Thoroughly clean the surface to remove dirt, grease, and contaminants. Grind the surface to create a profile for better bonding. Repair any cracks or holes in the substrate.


2. Incorrect Primer Application:

Problem: An improperly applied primer can lead to poor adhesion and premature failure.

Solution: Apply the primer evenly according to the manufacturer's instructions. Ensure the primer is fully cured before applying the PU coating.


3. Excessive Coating Thickness:

Problem: Applying too thick a coating can cause issues like slow curing, cracking, and delamination.

Solution: Follow the manufacturer's recommended thickness guidelines. Apply the coating in multiple thin layers to ensure proper curing.

4. Improper Curing Conditions:

Problem: Exposure to extreme temperatures, humidity, or direct sunlight during the curing process can affect the quality of the flooring.

Solution: Maintain optimal curing conditions, including temperature and humidity control. Avoid exposing the newly installed flooring to direct sunlight or drafts.


5. Lack of Professional Installation:

Problem: Improper installation techniques can lead to a variety of problems, including poor adhesion, uneven surfaces, and premature wear.

Solution: Hire a professional installation team with experience in PU flooring. Ensure they follow industry best practices and use high-quality materials.
