had a problem with kleer on my hms defender. caused yellowing and made localised crazing. now, this morning i had a chat with our flooring rep. this is what he told me..... kleer is non profitable to its manufacturer and has been downscaled with a view to discontinuation. kleer was formulated years ago to deal with quarry tiles, linoleum and asbestos thermoplastic tiles. historically darker colours. now with the current trend of pure vinyl and laminate, kleer will yellow. hence nowadays , floor gloss is completely opaque and formulated not to discolour. lighter aesthetic tones in flooring dictate that a floor treatment should maintain clear with no residue. when i asked him about kleer he told me that the formula has changed from what it was and its a cheaper and inferior product to what it used to be years ago. no floorcovering manufacturers reccomend it. do we really trust this stuff?
