i just purchased a new 8x10 plush carpet for my family room.paid quite a bit for it i felt it would be wise to protect it.that was mistake i purchased scotch gaurd carpet protector sprayed on as directed after vacuuming well.three days later i went to vacuum rug and could not vacuum stuck to rug like there was glue on it.we called scotch gaurd and told them what happened.they said it was late in the day inform there chemist and have him call us.it's been more than a week and i haven't heard a word from them.stay away from this product if you would really like to protect your rug.
