Downloads & documents
The stated values represent typical product characteristics and are not to be construed as binding product specifications.
Field of application
- Strengthening of strongly weathered and loose surfaces
- Stones and mineral building materials that are reasonably solid in their original condition
- Especially uniform strength profiles can achieved if used in combination with KSE 100
- Alternative product to KSE OSH with significantly improved properties
- Gel release rate approx. 30%
- High penetration depth
The substrate must be clean, dust-free and dry.
Any construction defects such as cracks, cracked joints, defective connections, rising damp and hygroscopic moisture must be remedied in advance.
Perform any necessary cleaning gently, e.g. by spraying with cold or warm water or by steam-cleaning; use rotec soft whirl jet technology or Remmers cleaning products (e.g. Traffic Film Remover (0671), Clean FP (0666), Clean AC (0672), Combi WR (0675)) on tough stains.
To avoid material loss of the substrate, an initial strengthening with KSE 100 or an other suitable strengthener can be carried out before any cleaning measure.
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 spray application is not possible, apply using a well-saturated brush.
Take appropriate measures to protect adjacent building elements and materials that should not come into contact with the product.
Remove any excess impregnation agent within 1 hour using V 101 thinner.
Protect freshly treated surfaces from driving rain, wind, sunlight and condensation.
Working tools / cleaning
Solvent-resistant low-pressure conveying and spraying apparatus, liquid pumps, brush, surface brush and lamb's wool roller
Tools must be clean and dry.
After use and before prolonged interruptions of work clean tools with Thinner V 101.
Ensure that any residue from cleaning is disposed of correctly.
Storage / shelf life
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.
After every use, close containers so that they are air-tight, since silica gel reacts with moisture (in the air).
Between 0.3 l/m² and several l/m² depending on the type and condition of the substrate and the specific application
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.
Carry out a quantitative analysis of aggressive salts if there are any salts present that could damage building materials.
High concentrations of harmful salts can cause major structural damage that impregnation cannot prevent.
Residue (e.g. surfactants, wax) from previous cleaning measures can have adverse effects on the treatment and must therefore be completely removed.
Application of restoration mortars, hydrophobizing primers and paints:
After application, the active ingredient "silicic acid ester" leads to a temporary water-repelling effect that disappears during the course of gel formation (reaction time: at least 28 days). Remmers Restoration Mortar, Funcosil impregnation agents and paints can be applied only after the gel formation is completed. If strengthened surfaces still show a water-repelling effect after more than 4 weeks reaction time, this can be suppressed by wetting the surface with alcohol or de-tensioned water.
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.
