Question 1

Can you put epoxy over ceramic tile?

Accepted Answer

Yes, epoxy can be installed over ceramic tile, but the tile must be prepared properly first. Ceramic tile is usually smooth and glazed, so it needs mechanical grinding to create a rough surface that the epoxy can bond to. Without this step, the epoxy may peel or lift over time.

Question 2

Can epoxy be applied over porcelain tile?

Accepted Answer

Yes, but porcelain tile is one of the harder surfaces to coat because it is dense, smooth, and non-porous. A professional installer needs to grind the surface, check the condition of the tile, repair damaged areas, and use the right primer before applying epoxy.

Question 3

Will grout lines show through epoxy?

Accepted Answer

Grout lines can show through if they are not filled and levelled before the epoxy finish is applied. This is often called ghosting or telegraphing. A proper levelling layer helps cover the grid pattern and creates a smooth surface before the final coating.

Question 4

Do loose tiles need to be removed before epoxy?

Accepted Answer

Yes. Loose, hollow, or cracked tiles should be repaired or removed before epoxy is installed. The epoxy floor is only as strong as the surface underneath it, so unstable tiles can lead to cracking, lifting, or failure in the new coating. The Tile Council of North America notes that hollow or loose tiles can happen when tile loses its bond to the subfloor.

Question 5

Is it better to remove tile before installing epoxy?

Accepted Answer

It depends on the condition of the tile. If the tile is solid, well-bonded, clean, and properly prepared, epoxy over tile can be a smart way to avoid demolition. If many tiles are loose, cracked, contaminated, or uneven, removing the tile may be the better long-term option.

Question 6

Can epoxy go over bathroom or kitchen tiles?

Accepted Answer

Yes, epoxy can be installed over bathroom and kitchen tiles when the surface is stable and properly prepared. These spaces need extra attention because moisture, grease, soap residue, and cleaning products can affect adhesion. Professional cleaning, grinding, moisture checks, and priming are important before coating.

Question 7

Can I use a DIY epoxy kit over tile?

Accepted Answer

DIY epoxy kits usually do not include the equipment needed to grind tile properly or check for moisture and hollow tiles. Because tile is difficult for epoxy to bond to, professional preparation is strongly recommended. Skipping the prep can cause peeling, bubbling, or visible grout lines.
