We're in the process of thinking about doing our floors. I know polyurethane is a bit toxic so wanted to avoid it. We do get ppl who sell non-toxic alternatives but they take like 2 days to harden & cost a fortune. I've heard of something else you can put on wooden floors to seal & protect them which also looks good. I just can't remember what it is. I think maybe linseed oil ? Anyone know or has done their floors like this ? What were they like to clean ?
