Superior adhesion for epoxy resin flooring on tiles

Why glazed tiles need a primer

Glazed ceramic and porcelain tiles often have a dense, low-porosity surface. Epoxy resin needs a mechanical or chemical key to hold onto; without a primer, the cured coating can form a weak interface with the tile. A purpose-made primer like Epoxyprimer is formulated to bridge that gap.

It is designed for reliable adhesion on ceramic tiles and other stable substrates such as concrete, screed, and timber. Because it is water-based and odourless, it is suitable for indoor floor preparation.

Application steps for a lasting bond

Primer adhesion is only as good as the preparation. Start by ensuring the tiles are clean, dry, and free from dust, grease, or loose grout. On particularly smooth or sealed tiles, a light sanding or degreasing step may be required before priming.

• Inspect the floor and repair any cracked or loose tiles before priming.
• Apply the mixed primer with a roller, brush, or spatula for even coverage.
• Use around 100–300 g/m² depending on how porous the surface is.
• Allow 24–48 hours for the primer to cure before pouring the resin coat.

When this matters

Primer choice matters most in high-traffic areas, on smooth ceramic surfaces, or where the subfloor may expand and contract. If you skip this step, resin coats are more likely to lift, crack, or form bubbles at the tile interface.

For the final finish, a durable top coat such as Prolux PU coating can be used over a primed tile floor, particularly where UV resistance and abrasion resistance are useful.
