DIY: How to Make an Epoxy Flake Floor Repair 

Materials to Repair an Epoxy Flake Chip:

• Poly 90 Low Odor-Polyaspartic Coating
• High-grit sandpaper
• Paintbrush
• Painter’s tape
• Disposable gloves
• Matching epoxy flakes

1. Surface Preparation

• Clean Thoroughly: Clean the affected area with a strong degreaser to remove all dirt, grease, and contaminants. Rinse thoroughly and allow it to dry completely.

• Sand for Adhesion: Lightly sand the damaged area and a few inches surrounding it with medium-grit sandpaper (80-120 grit). This creates a "key" to which the new epoxy can adhere. Feather the edges of the existing coating to ensure a smooth blend.

• Remove Dust: Use a vacuum with a fine filter to remove all sanding dust and debris, or wipe the area with a tack cloth for a pristine surface. Avoid using water.

2. Polyaspartic Coating Application

• Mix Precisely: Carefully measure and mix the polyaspartic coating according to the manufacturer's instructions. We recommend Poly 90. Incorrect ratios can lead to curing problems. Mix thoroughly for the specified time.

• Apply Evenly: Using a brush, roller, or squeegee, apply a thin, even layer of the mixed polyaspartic coating to the prepared area. Overlap the sound coating slightly for a strong bond.

3. Flake Application

• Broadcast Immediately: Generously sprinkle the matching epoxy flakes onto the wet surface after applying the polyaspartic coating. Lightly press them in for proper adhesion. Aim for a slightly heavier distribution than the surrounding area.

• Remove Excess: Once the polyaspartic coating has partially cured, gently sweep or vacuum away any loose, unbonded flakes. Also, remove any tape that was used.

4. Finishing Touches

• Sand down the area to match the floor surrounding it.

• Second Coat: Apply a second thin layer of clear epoxy for deeper repairs or a smoother finish.

• Cure Properly: Allow the repaired area to cure entirely according to the manufacturer's instructions.

• Clear Top Coat (recommended): A clear top coat over the repaired area (or the entire floor) will provide extra protection and help the repair blend in better.

Important Considerations for a Flawless Finish:

• Ventilation: Work in a well-ventilated area to minimize exposure to epoxy fumes. Use fans to circulate air.

• Safety First: Wear appropriate PPE, gloves, eye protection, and a respirator.

• Color Matching: Obtain flakes that closely match the floor color.

• Professional Help: Consult a professional for extensive damage or complex repairs.

Preventative Maintenance: Keeping Your Floor Looking Its Best

• Regularly sweep and mop the floor with mild, pH-neutral cleaners.
• Avoid dragging heavy objects across the floor.
• Place protective mats in high-traffic areas.
• Promptly clean up spills.
