How do you cover bathroom tiles with resin?
Step-by-step guide for a waterproof decorative tile finish
Transforming outdated or damaged bathroom tiles with a sleek resin finish is an excellent way to refresh your space, add a waterproof layer, and achieve a modern decorative look. This guide explains the process from start to finish, helping you avoid common pitfalls and choose the safest, most durable approach.
What You’ll Need
- “Epoxyprimer” – Universal Water-Based Two-Component Epoxy Floor Primer: A primer for ensuring proper adhesion between your tiles and resin.
- “Vertical Glass” – Thick Resin Decorative Wall Coating: For decorative waterproof topcoats on walls or vertical tiled surfaces.
- Sanding block or fine-grit sandpaper
- Strong degreasing cleaner
- Microfibre cloths
- Mixing buckets or containers
- Spatula or roller (for resin application)
- Protective gloves and mask
Step 1: Prepare and Clean the Tiles
Thoroughly clean and degrease your tiles to remove any soap scum, grease, or dirt—these will affect resin adhesion. Use a strong degreasing solution and rinse well to remove any residue. Dry the tiles completely with a microfibre cloth and allow all surfaces to air dry for at least an hour before moving to the next step to ensure there is no moisture trapped beneath the resin.
This stage is crucial: insufficient cleaning can cause peeling, bubbling, or uneven curing later on.
Step 2: Sand and Prime the Surface
Sand the tiles lightly for better adhesion using a fine-grit sanding block. This helps the primer and resin grip the glazed tile surface, preventing de-lamination. After sanding, wipe away all dust with a damp cloth, then let the tiles dry thoroughly.
Next, apply an epoxy primer for optimal bonding. Using a specialist tile primer such as “Epoxyprimer” – Universal Water-Based Two-Component Epoxy Floor Primer ensures that your resin coat securely adheres to even glossy glazed ceramics. Follow the manufacturer’s instructions for mixing, applying evenly with a roller or brush, and allowing the full curing time—typically 24 to 48 hours—before moving on.
Step 3: Mix and Apply the Resin Topcoat
Once your primer is fully cured, it’s time for the resin coating. For vertical wall tiles or areas prone to splashes, “Vertical Glass” – Thick Resin Decorative Wall Coating offers a decorative, highly water-resistant finish. Always read the instructions: measure the two resin components precisely and mix resin slowly to avoid bubbles.
Pour the resin onto the tiles in manageable sections and spread with a spatula or brush for full, even coverage. This product is designed to stay in place without self-levelling, allowing you to create custom textures or finishes if desired. For a glass-like look, finish with a smooth application; for more protection or a satin effect, apply slightly thicker and sand gently after 48 hours.
Step 4: Let the Resin Cure Fully
The final curing process is essential for a hard, durable, and waterproof surface. Work in a well-ventilated space and avoid touching, splashing, or using the tiles for at least 48 hours—preferably longer in cooler conditions. The resin should not be exposed to water or steam during this time.
Once fully cured, wipe the surface gently with a non-abrasive cloth. The result is a modern, decorative, glossy finish that transforms your bathroom tiles into a seamless, easy-to-clean surface.
Tips and Troubleshooting
Temperature and humidity can affect resin flow and curing—always work in optimal conditions. Plan for adequate ventilation, and keep the bathroom pet- and dust-free until the surface has fully set. Always patch test your primer and resin on a small inconspicuous area to check compatibility, especially if dealing with unusual or highly glazed tiles.

Frequently Asked Questions
Is it necessary to use a primer before applying resin to bathroom tiles?
Yes. An epoxy primer is essential for strong adhesion of resin to glazed or ceramic tiles, preventing future peeling.
What type of resin should be used on wall or vertical bathroom tiles?
A non-self-levelling, thixotropic resin like Vertical Glass is recommended for vertical tile surfaces.
How long should I wait before using the bathroom after resin application?
Allow at least 48 hours for curing, or longer in cool/damp conditions. The surface must be fully hard before exposure to water.
Can resin be applied over old or cracked bathroom tiles?
Yes, but cracks should be repaired and tiles must be stable and clean before proceeding with primer and resin.
How do I clean and maintain bathroom tiles finished with resin?
Use non-abrasive cloths and mild cleaners. Avoid harsh chemicals or scrubbing pads that might dull the shine.
What should I do if the resin does not adhere properly to the tiles?
Poor adhesion indicates issues with cleaning, sanding, or priming. Remove loose resin and repeat preparation steps.
Does a resin coating provide waterproof protection for bathroom surfaces?
Yes, when properly applied and cured, resin forms a highly waterproof and stain-resistant layer suitable for wet areas.
