    Default Adhesive staining on terrazzo

    Has anyone run across old (about 80+ year old) terrazzo that over the years has had carpet or tile adhered to it by glue and when the flooring surface and glue was removed it looked dark and stained? I ran across this twice recently and no matter how much cleaning I did and grinding no lower than 50 grit it still looks terrible.

    Any ideas on what could be done to remove the adhesive stains if that is what they are?

    Some stains will not come out completely. Did you cut with metal or resin. You can try a couple of things.
    1 Klenztone Ive not seen much result but many rave about it,but I always cut with metals first.
    2 Peroxide 20% ( 40 volume is 12% still works just slower) spread it out let it dry.On bad areas you can spread it out cover with plastic overnight.
    Some guys like bleach,I dont because is a corrosive .

    Hydrogen Peroxide poultice in high concentration left over night has worked for me in the past. An old terrazzo guy in Florida told me that. Hoboal.

    Thanks Ted I will give that a try. Only issue I see is that the area in question is about 800 sq'.

    Get the peroxide at beauty supply and do a test.
