I am putting down NOFMA 20mm thick T & G oak flooring. Once it's put down, I have to sand it and then I was told that I have to fill the gaps with the sanded sawdust. This sawdust should be mixed with what??? . I am not sure what is the best subtance to use, it should be fexible though, as wood moves. Does anyone know?
Also after all this as my final finish, I am going to either oil or wax it , but not sure which yet. I need to know what is better for spillages, as some of this oak floor will be in the kitchen area. Can anyone advise?
