A Grade Floor Sanding & Polishing is a family owned business operated by Jeff Milner in Brisbane, Australia. Because we have a young family were very concerned about the health of the environment, and the people in it. After learning about the damage solvent-based polyurethanes can cause we resolved to supply and using non-toxic waterborne polyurethanes, hard wax oils & organic oils. Our aim is to supply our customers with top quality workmanship in the healthiest possible way. The products we use are extremely durable and are the result of 20 years of research by the Swedish company BonaKemi, world leaders in waterborne polyurethanes.
