I'm trying to bring my house back to it's original 1900's feel. I have hardwood floors in the whole house. The kitchen and bathroom were covered with lenolium a few different times. I just recently pulled the lenolium up in both rooms and i am left with the black paste adhesive that is now worse than tar. I have tried everything. I was told i need a scarifier on a buffer,is this a good idea? I am in no way wanting to replace this floor or lay something over it. Any suggestions would be very helpful.
