How to use
Shake the container before use. The detergent can be used undiluted or in a solution of Ferrex in water. The dilution is done depending on the degree of contamination. Test first on a hidden surface to determine the dilution and how the stone reacts.
Medium contamination/light discoloration 1:3 in water
Severe contamination/extensive discoloration 1:2 in water
Extreme cases 1:1 in water
The solution is applied directly to the surface, by pouring or spraying. It is homogenized with a mop.
In extreme cases, the surface is rubbed with a brush or an abrasive sponge. Let it act for 3-6 hours then wash with plenty of clean water. If the stains persist, repeat the operation after 2 days.
When using it to remove adhesive or grout residues, let the detergent act for only a few minutes, depending on the degree of staining.
Using undiluted Ferrex is only done in cases of severe contamination, where the diluted solution did not work.
Coverage/consumption:
Average contamination: 30 sq m/liter (1:3 mixture)
Severe contamination: 20 sq m/liter (1:2 mixture)
Extreme contamination: 10 sq m/liter (1:1 mixture)
Storage: Keep in a dry, cool place, protected from frost.
Shelf life: max 4 years, in the container sealed.
Important:
Protect acid-sensitive surfaces from splashes.
Some rocks may darken after treatment, but the effect will wear off over time.
DO NOT use the detergent on highly polished surfaces.
On limestone (travertine, marble, limestone) with an unpolished finish, the effects are limited.
Protect the surface from water and moisture after treatment. Waterproofing with External Stone Sealer or Mattstone h1O is recommended after using Ferrex.
For small rust stains and on limestone surfaces, use LTP Rust Stain Remover.
Caution: Keep out of reach of children. Avoid contact with skin and eyes. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. Wear suitable gloves and eye protection. If swallowed, do not induce vomiting. In case of accident or if you feel unwell, seek medical advice immediately and show the label/container.
