Features and Benefits
- Treated porous, mineral substrates show
very good water and oil repellency
- Treated surfaces remain clean for longer
times and are more easy to clean (common liquids like coffee, coke, oils and
dark liquids are easily removed)
- Weakens the adhesion of chewing gum or
posters to e.g. facades
- Slows down the growth of microorganisms
such as mold and algae
- Helps avoid unsightly dark water streaks
- Highly reactive and resistant against
alkali
- Generates water-vapor-permeable,
colorless impregnation
- Reduces the uptake of water and soluble
salts (e.g. chlorides)
- No formation of sticky silicone films
- Can be diluted using demineralized water
- Suitable for the treatment of
hydrophobated substrates
Preparation before applying HydroLAN
Wood
- Ensure that the façade will be treated is clean and dry.
- Imperfections such as cracks, cracked joints or defective
seams must be repaired using appropriate methods. Mortar used for repairs must
be fully cured and surface dry.
- Always use clean application equipment to avoid contaminating
the façade that will be applied with Protectosil SC Concentrate.
Application
Guide
- The recommended application method for Protectosil SC
Concentrate is with HVLP (High Volume Low Pressure) equipment. Product
application using airless sprayers (low pressure, so called ‘flooding’ method)
is also possible if the substrate is sufficiently absorbent. The ready-to-use
solution is best applied starting from the bottom and going up the wall. This
avoids pre-treating the substrate with run-off from above.
- Some substrates such as limestone are less reactive. In these
cases the effect may take some days to fully develop. The application should be
continuous and uninterrupted so that no overlapping occurs
- In some cases (especially on very coarse and very porous
substrates) the easy-to-clean effect of Protectosil SC Concentrate may be
enhanced by additional treatments. The amount of product required for the
second and all subsequent treatments is considerably less.
- In the case of polished stone (e.g. marble) simply apply
Protectosil SC Concentrate once with a cloth, microfiber glove or other
suitable aid by polishing until a liquid film is no longer visible.
Significantly less product is required for polished surfaces (about 30 g/m2)
compared to rough ones.
- Protectosil SC Concentrate comes with high concentrate
formula. Thus when it is used diluted using demineralized water, the suggested
ratio will be 1:8
The application is recommended if air
and substrate temperature are between 50 C and 400 C.
Protectosil SC Concentrate should not
be applied during rain or strong wind.
Non-absorbent substrates such as, for
example, glass, wood, plastic and metal cannot be treated with Protectosil SC
Concentrate.
