Belzona Facts
During a major refurbishment of this Grade 2 Listed Building, the main contractor started repairing the sandstone on the window frames with cement based products. The Local Authority was not happy with the quality or colour matching of these cement repairs so they told the contractor to use Belzona 4141 for the rest of the project following several other local projects recently completed for them with Belzona 4141. The stone coloured belzona 4141 provides a very close match colour and texture wise to natural sandstone.
