Surface Preparation

Proper surface preparation is one of the most important factors affecting the performance and service life of epoxy flooring systems.

Before application:

• The concrete surface must be sound, dry, and clean
• Weak concrete layers and curing compounds must be removed
• The surface should be mechanically prepared to create sufficient adhesion
• Cracks and surface defects should be repaired with suitable repair mortars
• Surface moisture levels must be checked and rising damp problems must be eliminated

A properly prepared substrate ensures stronger adhesion, better durability, and improved coating performance.
