Thoroughly Clean and Dry the Surface Before Applying Epoxy Resin

Why Thorough Cleaning and Drying Matters

Dirt, grease, dust, and residual moisture are leading causes of weak adhesion between floors and epoxy coatings. Whether you are working on concrete, wood, screed, or tiles, proper cleaning removes all contaminants, giving the resin or primer the best chance to bond effectively. Taking time to dry the surface thoroughly also prevents bubbles, delamination, and uneven curing.

Best Practices for Cleaning and Drying

• Remove debris: Sweep or vacuum to clear away dust, loose particles, or old coatings from the floor.
• Degrease: For oil or grease stains, use a suitable floor degreaser or mild detergent. Rinse thoroughly and repeat if necessary.
• Wash and rinse: Mop or wash the floor, being careful to avoid leaving standing water—particularly important for porous materials like concrete or timber.
• Allow to dry: Ensure the floor is completely dry before proceeding. For best results, let the area air dry for at least 24 hours, or use heaters or dehumidifiers in humid or cold environments.

For optimal results on varied surfaces, applying a compatible primer like our “Epoxyprimer” – Universal Water-Based Two-Component Epoxy Floor Primer can further improve adhesion and ensure a stable base.

When This Matters Most

Vigilant cleaning and drying are crucial if you’re resurfacing high-traffic floors, treating previously oiled or painted spaces, or working with absorbent substrates. Ignoring proper preparation can result in premature wear or the need for costly repairs.
