|Methods of application||
Weiss EXTRA.KT removes deep and stubborn oil, fat and bitumen stains from all types of natural stone surfaces, concrete and stone paving, and plaster walls.
EXTRA.KT is a solvent paste that draws out oil and fat stains from deep below the surface and deposits the contaminants into the paste as it slowly dries. Once the paste has dried out on the surface it is simply brushed away, taking the stains with it.
Cleaned surfaces should be treated with a WEISS water-based impregnator such as StainProtect PROFI to provide protection against new oil and grease staining.
