Tackling Epoxy Grout Residue: Why CR10 Is the Professional's Go-To

Epoxy grout has become the go-to choice for tiled surfaces that need real staying power, from commercial kitchens and leisure centres to residential wet rooms. It is strong, waterproof and stain-resistant. The catch is the cloudy haze it can leave behind, a stubborn film that normal cleaners simply cannot shift. This guide explains what causes epoxy grout haze, why standard products fail, and how to remove it properly with Fila CR10.

What causes epoxy grout haze?

Unlike cement-based grout, epoxy is made from resins and hardeners. Once set, it forms a dense, non-absorbent surface that resists water and dirt, and the same toughness that makes it durable makes its residue hard to remove. If residues are not thoroughly cleaned during installation, they bond to the tile and leave a stubborn, cloudy haze that attracts dirt and dulls the finish. Even experienced tilers can be caught out. A minor clean-up delay or a missed patch is enough for the leftover material to cure, at which point you are dealing with a chemical bond rather than surface dirt.

Why normal cleaners do not work

General-purpose and bathroom cleaners are designed for surface dirt, not cured resin. They cannot break the chemical bond, so they smear the haze around without lifting it. That is why a product formulated specifically for epoxy residue is needed.

How to remove epoxy grout haze with Fila CR10

Fila CR10 is a concentrated, high-viscosity gel made specifically to remove epoxy grout haze and film from dense surfaces such as porcelain, glazed ceramic, glass mosaics and polished quarry tiles. Its gel consistency lets it cling to vertical surfaces without running off, and it softens epoxy deposits without affecting the tile underneath. It is ready to use straight from the bottle, with a pleasant almond fragrance.

To use it: shake the bottle, apply undiluted with a flat brush so all residues are covered, and leave it to dwell for about 30 minutes to soften the film. On walls, scrub with an abrasive sponge or spatula; on floors, use a single-disc machine with a suitable pad. Rinse thoroughly with water. For particularly stubborn haze, apply a second round and leave it longer. Do not use CR10 on very absorbent materials, wood or methacrylate surfaces, and always test metal surfaces and a small area first.

CR10 vs other Fila cleaners

It helps to match the product to the job. CR10 is the one for epoxy grout haze. Deterdek Pro is a buffered acid cleaner for cement grout haze and mineral residue on acid-resistant tiles, but not for natural stone. PS87 Pro is an alkaline degreaser and wax stripper for oils, grease and maintenance films. For resin-based grout specifically, CR10 is the right choice.

Frequently asked questions

Will CR10 damage my tiles?

No, when used as directed. It softens epoxy deposits without affecting the tile underneath. Avoid very absorbent materials, wood and methacrylate, and always test a small area and any metal first.

How long do I leave CR10 on?

Around 30 minutes to soften the film, then scrub and rinse. For stubborn haze, apply a second round and leave it longer.

What surfaces is CR10 for?

Dense, non-absorbent surfaces such as porcelain, glazed ceramic, glass mosaics and polished quarry tiles, the materials epoxy grout is most often used on.

Can I use it on walls?

Yes. Its gel consistency clings to vertical surfaces without running off, so it works on both walls and floors.

What is the difference between CR10 and Deterdek Pro?

CR10 removes epoxy (resin) grout haze. Deterdek Pro is a buffered acid cleaner for cement grout haze and mineral residue on acid-resistant tiles, not for natural stone.
