Before application, test the product on a small area to check the material’s resistance to VIACEM®. The product can be used undiluted or diluted with water, depending on the type of deposit and the cleaning required.

• Undiluted: for heavy, stubborn limescale deposits and substantial cement slurry residues.
• Diluted with an equal part of water: for cleaning that requires a normal descaling and limescale-removing action and for neutralising surfaces after previous alkaline cleaning.

How to use the product

• Apply VIACEM® evenly to the surface and, where possible, leave it to work for a few minutes.
• Scrub the surface with a BROWN BUFFER PAD, BROWN DISC, nylon brush, TYNEX DISC or carborundum brush until the dirt and deposits have been removed.
• Repeat the cleaning process if necessary.
• Always rinse thoroughly with plenty of water.

Approximate coverage

Coverage varies according to the type and amount of deposits and the absorbency of the material:

• for intensive cleaning: 1 litre per 3–6 m²;
• for normal cleaning: 1 litre per 8–12 m².
