I run a small carpet cleaning firm and occasionally sand and varnish wood floors for my domestic customers using hire equipment (drum and edge sanders).
However, I have been asked to look at improving a large wooden floor of aprox 70 sq metres in a pub. The floor was only laid 3 months ago but now after Christmas /New year has already lost its bright new look and is looking grubby with ingrained soil. How can I test to see if the boards where sealed. To be honest, I think it would be a huge job for me to sand the wood back to clean and really am looking for a suitable product to clean the floor as best as possible and then re seal.
Any advice greatly apprecaited.
