Bob De Groot painting contractors recently complete a full sandstone block restoration, removing layers of old and flaking paint from a home in Tunbridge in Tasmania's midlands. The new technology we are now using is safe even on soft surfaces like sandstone. Its a clean safe process using mainly water pressure but designed to minimise any distruption to the substrate. This method has been working very well for cleaning up sandstone homes and buildings and is a cost effective solution compared to other methods.
