Epoxy paint provides high durability in industrial and commercial floor coatings. However, surface preparation is crucial for achieving the full effectiveness of epoxy paint application. This article details the steps involved in epoxy paint surface preparation , ensuring a long-lasting coating with proper application.
1. Cleaning the Surface
Before applying epoxy paint, the surface must be free of dust, oil, and dirt. Oil residue, in particular, prevents epoxy paint from adhering. Therefore, thoroughly clean the surface using industrial degreasers and detergents, then rinse thoroughly with plenty of water.
2. Mechanical Preparation (Sanding or Sandblasting)
Epoxy has poor adhesion to smooth surfaces. Therefore, roughen the surface by sanding, sanding, or milling. This will help the epoxy paint adhere more strongly.
3. Removal of Dust and Debris
Remove any dust and residue from mechanical work. Use industrial vacuums or compressed air to completely remove dust from the surface. This will ensure a homogeneous epoxy coating.
4. Humidity and Dryness Control
If the surface isn’t dry, the epoxy won’t adhere properly and will swell. Measure the moisture content of concrete surfaces. If the moisture is high, wait until the surface is completely dry or use dehumidifiers.
5. Primer Application
Using a primer prepares the surface for epoxy paint. Primer reduces paint consumption and improves adhesion on porous surfaces. Choose the right primer for the surface type.
6. Epoxy Paint Mixing and Application
Epoxy paints consist of two parts: component A (resin) and component B (hardener). Prepare the mixture according to the manufacturer’s ratios. Incorrect ratios prolong drying time and reduce strength. Mix the mixture thoroughly with a low-speed mixer.
