Aqueous protective agent for natural stone with a clay/mineral structure for protection against hygroscopic swelling
The stated values represent typical product characteristics and are not to be construed as binding product specifications.
The substrate must be absorbent, clean, free of dust and dry.
Perform any necessary cleaning gently, e.g. by spraying with cold or warm water or by steam-cleaning; use the rotec Soft Whirl Jet 25 l (5235) or Remmers cleaning products (e.g. Traffic Film Remover (0671), Clean FP (0666), Clean AC (0672), Combi WR (0675)) on tough stains.
Temperature of the material, air and substrate: from min. +8 °C to max. +25 °C
Apply the primer abundantly by flow coating without pressure (avoid misting), so that a 30 - 50 cm long liquid film flows down the surface.
Apply on one section at a time, moving from top to bottom, and immediately go over with a large brush.
Repeat the application several (at least two) times (wet on damp) until no further material is absorbed by the substrate.
On surfaces where a spraying application is not possible, apply by brush or roller making sure the tools are always well saturated.
Protect freshly treated surfaces from driving rain, wind, sunlight and condensation.
Non-corroding low-pressure, conveying and spraying equipment, liquid pumps, paintbrush and flat brush
Tools must be clean and dry.
Clean tools with water after use and before any lengthy interruptions to work.
Ensure that any residue from cleaning is disposed of correctly.
If stored unopened in its original container in a cool, dry place and protected against frost, the product will keep for at least 12 months.
Use the contents of open containers as quickly as possible.
Shilf sandstone: 1.0 – 4.5 l/m² Red sandstone: 0.3 – 2.5 l/m² Tuff: 1.0 – 6.0 l/m² Brick: 0.2 – 3.0 l/m²
Apply to a large enough trial area to determine the precise amount required.
Deviations from applicable regulations must be agreed separately.
The relevant test certificates must be observed when planning and carrying out work.
The level of absorption is crucial for the impregnation agent to work at its best. This depends on the respective pore volume and moisture content of the building material.
Residue (e.g. surfactants, wax) from previous cleaning measures can have adverse effects on the treatment and must therefore be completely removed.
High alkalinity may reduce the effectiveness.
Larger quantities of leftover product should be disposed of in the original containers in accordance with the applicable regulations. Completely empty, clean containers should be recycled. Do not dispose of together with household waste. Do not allow to enter the sewage system. Do not empty into drains.
