Can I use this to stop mold stains on bathroom tile grout?
Yes. Cement-based grout will properly absorb and react with the treatment; vinyl based will not. Also, the speed with which the self-cleaning effects works depends on the amount of illumination.
Can I use this on my garage floor?
Yes. The sealing or densifying effect will occur even in the dark. However, the speed with which the self-cleaning effects works will depend on the amount of illumination on the area.
Will it work in a shady spot?
Yes. There is quite a bit of ambient light even in the shade; that is why we can comfortably read a newspaper there. Again, the speed with which the self-cleaning effect works will depend on the amount of illumination on the area.
On what different surfaces can I apply?
We have tested successfully on concrete, pavers, roof tiles, stone and the like. These surfaces contain calcium hydroxide (lime) – type materials that will react with the treatment and close surface pores. However, any surface that absorbs water will absorb the treatment; the treatment will often seal these surfaces permanently as well. A patch test may be necessary on the specific surface.
Can I apply this on painted surfaces?
We do not recommend application on painted surfaces, unless the paint is inorganic, as is the case with stains, or colorants, commonly used in the concrete pavers.
Can I apply this on a terrazzo floor?
Cement-based terrazzo, commonly used outdoors, is compatible with the treatment. A patch test may be necessary on the specific surface. Application on epoxy-based indoor type terrazzo is not recommended.
Will it effect the color of the floor?
No. When properly used, treatment is not detectable. However, if the treatment is over-applied, it may lighten the surface color. Following the application instructions will prevent over-application.
Will it be slippery when wet?
No. When properly used, treatment is not detectable. There is no evident change to the surface coefficient of friction.
Will I ever be able to paint a surface after it has been treated with SelfClean?
Yes. The surface still absorbs paint; also paint is opaque and will prevent light from activating SelfClean.
How long can I expect the SelfClean to work?
The changes in the concrete are permanent. When properly applied, we have so far documented SelfClean functionality for 5 years.
I have a restaurant and the wall around my outside exhaust vents gets very greasy. Will this work on food grease?
SelfClean will seal all concrete-type cementitious surfaces, even on vertical applications.
Do you know if it will stop weeds from growing in the pavement cracks?
It may, but this depends on the substrate and the application details; for example, is the crack illuminated? How well did the treatment seep into the crack? Did the crack occur after application, etc?
If I leave a car parked on a treated surface for an extended period of time, will selfclean degrade the surface of the tires at the point of contact?
No. Selfclean requires sunlight to work; the tires will prevent illumination.
Is it environmentally friendly?
We are advised that the treatment satisfies the labeling requirements for green products, as defined by green seal (iso 14020 and iso 14024).
Is it safe for children and pets to walk/play on it?
Yes. A treated surface is not distinguishable from an untreated surface.
