Removing Bitumen from Concrete
Tile Doctor has a product for most things in its range and I’m happy to say I was able to clean up the floor using Tile Doctor Remove and Go which was left to soak into the bitumen to soften up before attacking it with a black pad fitted to a Numatic buffing machine which was weighted down to improve traction. Some areas were stubborn to remove as you can imagine so to soften it further I used an Earlex Steamer and finally a Tile Doctor Diamond encrusted burnishing pad to cut into the concrete very slightly and remove most of the bitumen that had sunk below the surface.The results were as good as they could be and the customer was very pleased as she said it made the whole room look much lighter.
