PVC flooring: how to repair it

What You’ll Need

• CROP 2K Fiberglass Putty – 750 ml + Hardener – for filling cracks, deep dents and holes in PVC flooring
• “Icrystal” – Clear Epoxy Resin – Odourless Formula – Up to 1.5cm – for transparent and durable surface repairs on PVC flooring
• Sandpaper (various grits, starting around 120 up to 400)
• Protective gloves and a dust mask
• Mixing spatula and flat applicator
• Clean cloths and mild cleaning solution

Essential Tools and Workspace Setup

Organise your workspace with all the necessary materials at arm’s reach. Use gloves and a dust mask to protect your hands and lungs while sanding, handling putty, or applying resin. Lay down dust sheets for easy post-job clean-up, and ensure ample ventilation in the repair area for safety and optimal curing. A well-prepared workspace ensures a smoother process and a professional-looking result.

Step 1: Assess and Prepare the Damaged Area

Start by carefully inspecting the PVC flooring for cracks, chips, dents or worn spots. Remove any loose debris, dust or residue from the damaged area using a clean cloth and a mild cleaning solution. For the best adhesion, deep cracks or holes must be properly cleaned before repair — scrape out loose fragments if necessary. Allow the surface to dry thoroughly before proceeding.

Step 2: Sand and Smooth the Surface

Lightly sand around the damaged area using fine-grit sandpaper. This helps to flatten rough edges and create a suitable profile for filler or resin to adhere to. Sanding too aggressively can damage the surrounding flooring, so maintain a gentle touch. After sanding, remove dust with a clean, damp cloth and let the surface dry completely.

Step 3: Fill Cracks, Dents or Holes

Mix your chosen repair compound according to the manufacturer’s instructions. For cracks or deep dents in PVC flooring, use CROP 2K Fiberglass Putty – 750 ml + Hardener for its fibreglass-reinforced strength and resistance to moisture. Apply the putty with a flat applicator, pressing it firmly into the damaged area and smoothing it flush with the surrounding surface. Pre-mixed two-part putties cure quickly, so keep your workflow efficient and clean any excess before it hardens.

Step 4: Sand, Clean and Apply a Clear Epoxy Finish

Once the filler is fully cured, sand the repair lightly until it is smooth and level with the floor. Remove dust thoroughly. For a transparent or glossy finish, use a suitable resin to seal and protect the repair. “Icrystal” – Clear Epoxy Resin – Odourless Formula – Up to 1.5cm is ideal for clear, durable coatings on PVC flooring. Mix and apply the resin as per instructions, allowing it to self-level over the area. Let the resin cure fully before resuming foot traffic.

Tips, Common Mistakes and Troubleshooting

Always follow the curing times for fillers and resins to ensure strength and adhesion. Good ventilation minimises odours and speeds up drying. Avoid overfilling or underfilling repairs, and blend edges so patched areas remain discreet. If colour matching is needed for visible repairs, consider specialist coatings like polyurethane products for paintable finishes. Always test in an inconspicuous area if unsure about compatibility or finish.

Finishing Touches and Maintenance Advice

Once your repair is fully cured and restored to a smooth, even finish, regular cleaning with non-abrasive products will help preserve the appearance of your PVC flooring. For long-term durability, consider using a quality floor polish or applying a compatible polyurethane coating for extra resistance in high-traffic areas. Promptly address future scratches and dents to prevent minor damage from spreading or worsening.
