Can I Apply Resin Over Old or Cracked Tiles? Expert Advice

← Back to How do you cover bathroom tiles with resin?

If you’re considering giving tired or damaged bathroom tiles a modern makeover, resin coatings can provide a seamless, waterproof and attractive finish. But is it possible to apply resin successfully over old—or even cracked—tiles?

Can Resin Be Applied Over Old or Cracked Tiles?

It is possible to apply resin over old bathroom tiles, including those that have minor cracks, provided you take the right precautions. The tiles must be securely attached to the wall or floor and thoroughly cleaned to remove loose debris, grease or any material that could hinder adhesion. For cracked tiles, any damage must be repaired so the surface is stable—this can involve filling cracks or replacing loose sections before priming and coating.

Crucial Preparation Steps for Lasting Results

Preparation is the key to a smooth, long-lasting resin finish on tiles. Begin by removing mould, limescale, or soap residues. Repair cracks using filler suitable for ceramics or tile adhesive. Next, apply a primer specifically designed for use on tiles, such as the Epoxyprimer, to ensure maximum adhesion between the tile and resin layer. Once the primer has cured, you can apply a resin wall coating—products like Vertical Glass are suitable for vertical surfaces, providing a glossy, washable, and water-resistant layer ideal for bathrooms.

When Does Resin Over Tiled Surfaces Make Sense?

Covering unsightly grout or patterns with a modern finish
Reviving old tiles when replacing them is impractical
Adding water resistance and ease of cleaning to high-moisture spaces

Choosing the right resin is essential—look for non-self-levelling formulations for walls, or glossy, scratch-resistant resins for decorative effects.
