Grout Haze Removal Pro Kit

The Pro Kit is for bigger post-installation cleans and for tilers and contractors who remove grout haze regularly. It has the same tools as our other grout haze kits, with 5 litres of Cleaner No.4 concentrate and a 5 KG Half Tub of Diamond Dust, a 220-grit diamond honing powder for extra cleaning power.

What’s in the kit

• TileMaster Cleaner No.4, 5 litre concentrate: a professional acid cleaner (Grout & Builders Dust Residue Remover – Acid Cleaner 4) for ceramic, porcelain and acid-resistant natural stone only. It does not tarnish aluminium or steel trims, taps, sinks or cookers.
• Diamond Dust Honing Powder, 5 KG Half Tub: a 220-grit diamond honing powder. Sprinkled on the floor before Cleaner No.4, it adds extra cleaning power. Never use it on polished or shiny floors.
• Scrub Pad – Tile and Grout Scrubbing: a heavy-duty, flexible scrub pad that cleans both tiles and grout lines, including uneven and textured floors. Rinse it with water after use.
• Aurora Spray Mop with 2 washable microfibre pads: a lightweight mop with an ergonomic handle and a 360-degree swivel head for corners and tight spaces. Never put Cleaner No.4 in the mop’s spray bottle: it can break the seal.

Who it suits

For larger areas and trades. Cleaner No.4 covers approx. 15 m² per litre of concentrate for grout haze removal (used at 1 part cleaner to 4 parts water), so the 5 litres in this kit cover around 75 m². Diamond Dust is made for contractors and stone restoration specialists. For smaller jobs, choose the Basic kit.

Suitable surfaces

• Ceramic tiles
• Porcelain tiles
• Acid-resistant natural stone only
• Kitchens, hallways, bathrooms, pool surrounds and changing rooms
• Diamond Dust: never on polished or shiny floors

Not suitable for: wood, vinyl, or acid-sensitive stone such as marble, limestone and travertine. Do not use on any polished or other acid-sensitive surface. Never use Diamond Dust on polished or shiny floors. If you are unsure whether your stone is acid-resistant, test a small, inconspicuous area first or contact us before use.

How to use

1. Protect yourself: wear protective gloves and eye protection. Wear safety goggles, gloves and a dust mask/respirator when handling the dry Diamond Dust powder.
2. Test first: always test on a small, inconspicuous area first. If you are unsure whether your stone is acid-resistant, contact us before use. Never use Diamond Dust on polished or shiny floors.
3. Sprinkle Diamond Dust: for extra cleaning power, sprinkle Diamond Dust onto the floor first.
4. Dilute Cleaner No.4: mix 1 part cleaner to 4 parts water (100ml cleaner to 400ml water) in a separate container. For grout haze, always use it diluted. The neat concentrate is only for rust marks on porcelain.
5. Apply directly to the floor: apply the diluted No.4 directly to the floor over the Diamond Dust and leave it to work for 5 minutes, keeping it wet so it does not dry on the floor. On a large floor, work in sections you can keep wet. Do not put No.4 in the mop’s spray bottle: it can break the seal.
6. Scrub: scrub the tiles and grout lines with the Scrub Pad on the mop, or with a TileMaster machine fitted with the tile and grout brush (machine not included).
7. Remove: take up the dirty solution with a clean mop, sponge or cloth, or extract the residue with a wet vacuum.
8. Rinse: rinse well with clean water.

Always test on a small, inconspicuous area first.
