I wanted to let you know that the double faced carpet tape you sold to us for our basement family room floor worked out great. We have an old basement and the floor had been painted and was not very clean. We wiped down the areas where the tape was to go to remove the dust as you suggested. We needed a couple more rolls to finish, so we picked up some at our local hardware store. It was definately not the same quality as yours and did not stick as well. Thanks for suggesting the tape to us it really works well.
