Weiss Extra KT: Oils, Wax and Tar
Extra KT removes deep and stubborn oil stains from all types of concrete and natural stone flooring and pavement surfaces.
How it works:
The special solvents within Extra KT attract oil which has migrated deep beneath the surface, drawing both oil and contaminants out into the slowly drying layer of Extra KT. Only a dry crust of material is left behind, to be brushed away, taking the stains with it.
- Gently removes deep stains without damaging the surface
- Spirits away stains otherwise impossible to remove in one process
- Effective for a wide variety of substrates – natural stone, concrete and gypsum
Odour: light solvent
- 150g pouch
- 750g tin
Extra.KT will keep for at least 12 months from the delivery date in its original packaging. Keep cool and dry, tightly sealed in the tin. Product that has not dried out remains fit for use.
How to use:
- Remove surface residues of oil, grease, mastic, bitumen etc using a scraper.
- Apply when the surface is dry and the temperature is between 5-25°C.
- Apply EXTRA.KT paste onto the area to be cleaned at a thickness of not less than 5 mm.
- Allow the paste to dry to a crust (may take 3 - 6 hours, longer in some conditions).
- The remaining dry crust, containing the residues of oil, solvents and bitumen, should be swept away and disposed of.
- If necessary, repeat the treatment.
- The area should then be cleaned with WEISS Grundreiniger (GR).
