Application Situation
Householder had a problem of cracks in the sandstone Mullions of his bay windows.
Application Method
Application was carried out in accordance with Belzona Know-How System Leaflet WPA-4. The cracks were opened out and filled prior to the whole mullion being skimmed with Belzona® 4141 tinted to match the colour. The original grooving on the stone was replicated in the Belzona® 4141.
Belzona Facts
If the Mullions had not been repaired then it would have resulted in them becoming unstable. Traditional repair Methods had failed and replacement units were unavailable.
