FERROLIT Water-Based Impregnator is a ready for use, solvent-free impregnation based on a silane/siloxane mixture emulsified in water. The product penetrates into the pore system of the stone. A polysiloxane results from the catalytic reaction. In addition, a reaction with the silicate substance of the stone takes place which results in high efficiency.
Solvent-free, no VOC
Application also possible on surfaces with residual humidity
Fast formation of the hydrophobic effect
Reduction of water and dirt absorption during periods of moisture
Fast liberation of humidity during dry periods due to high vapour permeability
Maintenance of breathing properties because there is no surface layer
Resistance to UV radiation
Good alkali resistance towards mineral joint mortar
Coverage - approx. 5 - 15 m²/liter, depending on the absorptivity of the stone
Colour - Milky White
Density - approx. 1 g/cm³
pH value - approx. 7
FERROLIT Water-Based Impregnator is suited to achieve a water and dirt repellent effect on absorbent, mineral substances terrazzo, It is also very well suited for bricks, sand-limestone and mineral-based plaster.
Instructions for Use: Disregarding the processing guidelines can lead to irreparable damage!
Cleaning - The surface must be clean, completely dry and free from all layers. Ensure that outdoors stone does not contain any detrimental salts (nitrates, sulphates, chlorides) because these can reduce the absorptive capacity of the impregnating material. Depending on the type of stone and the degree of soiling, the following products can be recommended, please pay attention to our care recommendations as well as our specification sheets: AKEMI Stone Cleaner, AKEMI Algae and Moss Remover, AKEMI Wax Stripper, AKEMI Oil and Grease Remover Paste, AKEMI Graffiti-Remover. Rinse well with water after cleaning.
Preparation of a sample area - Before starting we recommend to prepare a sample area of 1-2 m² in order to examine the efficiency of the impregnation, to evaluate the appearance of the treated object (colour enhancement) and to ascertain the material consumption as exactly as possible.
Impregnating procedure -
The best conditions for impregnating are a cold object, an ambient temperature of 15-25°C and protection from humidity for approx. 24 hours. The stone must not be warmed up by an underfloor heating or direct sunlight.
The impregnating effect is sufficient for fissures which are smaller than 0.3 mm.
In general, one to two appliances wet-in-wet are sufficient.
Apply the product with a brush or a mop. Airless spraying equipment with low pressure (max. 1 bar overpressure) is suitable for treating façades using the flooding (multiple-coat) method and a jet distance of approx. 15 cm (condition: tubes and seals must be resistant to solvents). The impregnation is applied until it runs down 40-50 cm.
Approx. 20 minutes after application, respectively before drying of the impregnation on the surface, any excess which has not been absorbed by the stone has to be completely removed with a suitable cloth. Polished surfaces must additionally be polished again until any blooming on the surface is removed.
If the desired effect is not achieved or if the impregnation has been applied unevenly, it is possible to apply the impregnation once again. The water repellent effect develops after approx. 24 hours. Sufficient efficiency is reached after 1 week, complete hardening after 3 weeks.
Tools can be cleaned with AKEMI® Nitro-Dilution.
Special protective measure in case of spray application: avoid the formation of aerosols and risk to third parties. Do not breathe vapours (protective mask).
Ensure sealing of the reverse side and lateral surfaces of the stone, so that rising moisture cannot penetrate into the stone. In this context, we recommend the use of AKEMI Anti-Stain Coating 2015 to seal the reverse side and the lateral surfaces.
In case of loose laying outdoors it is recommended to treat the stone prior to laying from all sides with FERROLIT Water-Based Impregnator.
Impregnations do not offer sufficient protection against waterlogging.
If the treated area is cleaned, a drying time of 1 – 2 days (depending on the temperature) is necessary.
A treatment with FERROLIT Water-Based Impregnator prevents the stone from getting dirty again, respectively, the process will be delayed considerably. Should the surface become dirty again it can be cleaned much more easily.
Unsuited or aggressive cleaning agents, as well as pressure washers, may destroy the impregnation and the stone. We recommend using AKEMI Mild Stone Soap or AKEMI Crystal Clean only for the regular cleaning.
Product which has been inaccurately applied can possibly be removed with AKEMI Impregnation Remover.
Existing joints must be tested in view of their resistance to solvents. In case wetting agents had been used to smoothen joint fillers, they must be removed prior to application of the impregnation.
FERROLIT Water-Based Impregnator is not suited for glazed and non-absorbent surfaces.
In case of water absorption of the stone < 3% we recommend to use our solvent-containing products AKEMI Stone Impregnation.
A surplus of the product causes blooming and spotting.
Use AKEMI Liquid Glove to protect your hands during working.
Surfaces to be treated must be protected against direct solar radiation.
Protect synthetic materials which are not resistant to solvents, window- screens, parts to be varnished or objects situated in the area of working (cars, gardens). An evaluation of the impregnation according to its water repellent effect is not sufficient because this effect shows on the surface only.
The water repellent effect can be diminished or be invisible due to dust settings.
The colour of most stone surfaces will not or only slightly change. On quartzite and serpentine, a clearly recognizable colour enhancement occurs. Therefore it is recommendable to test on a sample piece or an inconspicuous area.
For adequate waste disposal container must be completely emptied.
When applying the product correctly it is not hazardous for health.
2 years if stored in a cool place free from frost in its tightly closed original container.
