How to Prepare Glossy or Glazed Tiles for Resin Application

← Back to How do you apply resin on tiles?

Applying resin to glossy or glazed tiles requires a bit of surface preparation to ensure the best possible adhesion and finish. A few careful steps will help you achieve a durable and attractive result.

Sanding and Cleaning for Proper Adhesion

Glossy and glazed tiles are naturally resistant to adhesives, which means resin may not bond well to their smooth, shiny surfaces right out of the box. Start by lightly sanding the tiles with a fine-grit sandpaper—this will gently roughen the surface and remove the sheen, improving the grip of any primer or resin layer that follows. Make sure to cover every area you intend to resin, including edges and corners.

Once you’ve finished sanding, thoroughly clean the tiles to remove dust, grease, and any remaining particles. Wipe them down with a damp cloth and allow them to dry fully before moving onto the next step. Even a small amount of moisture can interfere with how primers and resins bond to the surface.

Using a Suitable Primer

After preparing the surface, a quality primer is crucial for promoting long-lasting adhesion on ceramic or glazed tiles. Opt for a product designed specifically for hard surfaces, such as “Epoxyprimer” – Universal Water-Based Two-Component Epoxy Floor Primer. This primer can be rolled or brushed onto dry, clean tiles. Not only does it boost adhesion, but being water-based and odourless makes it comfortable for indoor applications as well. Allow it to cure as per the instructions before proceeding with your chosen epoxy resin.

When Extra Preparation Matters

Additional preparation is especially important if your project is in a high-traffic or wet area. In these situations, strong adhesion ensures the resin finish remains intact over time, reducing the risk of peeling. Skipping surface sanding or not allowing tiles to dry fully can lead to disappointing results or premature failure of the resin layer.
