What You’ll Need

• “Epoxyprimer” – Universal Water-Based Two-Component Epoxy Floor Primer: Essential for maximising adhesion when covering tiles with resin.
• “Prolux” – PU coating for tiles, concrete, plastic and metal – suitable for driveable surfaces: For durable, UV-resistant finishes especially in high-traffic or outdoor areas.
• “Vertical Glass” – Thick Resin Decorative Wall Coating: Ideal for vertical or sloping tiled surfaces if a decorative, washable wall finish is desired.
• “Trasparente” – Multipurpose Clear Epoxy Resin for Casting – Up to 2cm: Suitable for small, highly transparent coatings with self-levelling properties.
• High-grit sandpaper
• Microfibre cloths
• Protective gloves and mask
• Roller, brush, or spatula (depending on surface and product)

Step 2: Sand and Key the Tiles

Ceramic or glazed tile surfaces are naturally smooth and non-porous, which hinders resin adhesion. Sand the tiled surface evenly using high-grit sandpaper (120–220 grit works well) to create a uniform, matte texture. Focus on the tile faces and ensure grout lines are lightly abraded too.

Vacuum dust from the area, then wipe tiles with a microfibre cloth. This step prevents dust particles from mixing into the primer or resin layers and ensures optimal binding for the subsequent primer coat.

Step 4: Apply the Resin Coating

With the tiles now primed, it’s time to coat the surface with your chosen resin. Apply resin in controlled conditions—ideally, room temperature and low humidity—to reduce bubble formation and promote a flawless finish. Work in small sections for best control, and always wear protective gloves and mask.

For floors, a self-levelling product such as “Trasparente” – Multipurpose Clear Epoxy Resin for Casting – Up to 2cm is suitable for clear, thin coatings. For vertical walls or decorative features, use “Vertical Glass” – Thick Resin Decorative Wall Coating, which is formulated for vertical application without running or sagging. Spread it with a spatula for a smooth and even layer.

Allow full curing in a dust-free environment. If a second coat or additional finish is desired, wait until the first coat is completely firm.

Tips, Common Mistakes and Troubleshooting

• Avoid rushing surface preparation—thorough cleaning and sanding are essential for preventing peeling or bubbling later.
• Do not skip required priming steps—tiles without primer may cause resin delamination, especially in wet areas.
• Prevent trapped moisture under resin by allowing all cleaning steps to dry fully before progressing.
• Always measure and mix resin or primer components precisely to avoid sticky or undercured surfaces.
• If air bubbles appear when pouring resin, gently pass a heat gun or hairdryer over the surface at low power to release them before curing begins.
