http://www.bio8.co.uk/p-56/en701 this product i bought for a job i had last year in a brand new warehouse where the workers had been playing around in warehouse on forklift n left mark everywhere. It lifted some marks but nowhere near what i expected.
I spoke with company and they could not understand why it did not work. The batch number was checked out to see if any other problems with it but nothing showed. It maybe worth trying again.
Do you plan on using a buffer type machine or have pads on a doodlebug? I applied with a sprayer and used different xoloured pads on a doodlebug with little effect. I then used a ride on machine with pad to try n nothing.
We thought maybe floor had been sealed and was creating the problem.
Might be worth trying again or checking out other products.
