By the time I came in the floor had been triple stripped with Johnson Linosafe. Great product designed not to hurt natural rubber floors. Problem is that the finish on the floor could not come off with Johnson Linosafe even at 1:4. So here's the tip if you run into this situation it's called Emerald from Dustbane. We did a small test patch about 3'X3' at a dilution of 1:1. It removed the old wax without harming the floor.

Client had spent 3 weeks in these 2 gyms up until that point and had a 2 day deadline. I'm glad to say that after this process the deadline was met and the clients client was happy.
So what's the next step. For this client they want to leave the floor bear. I believe unfortunately that once waxed a floor almost always needs to be waxed, except in the case on concrete or natural stones. And I think that come October 1 after 1000 kids a day use this floor the client will have to put a sealer down on the floor. Fortunately the floor is prepped so all they will need to do is scrub the floor with Emerald at 1:40 and then apply 2 or 3 coats of either LinoBase for Johnson or Foundation from Dustbane. The deciding factor of course will be dollars. Linobase has optical brighteners that will help restore the original look of the floor where as Foundation is a great green certified sealer that will give the floor a uniform finish. By the way I think I forgot to mention that Emerald is also a green certified cleaner which Linosafe is not.
At the end of the day, please, leave the heavy lifting to the professionals. Your floors will last longer and your clients will be happier. Also remember that just because it says green it doesn't mean it doesn't work. In fact most green cleaners today are more effective than their non green competition.
