New Breakthrough with Poulticing

We have now accumulated a considerable amount of knowledge about the use of Poultices in stain removal. We were recently asked by a major Leeds contractor, on behalf of a major Leeds property company, to examine the cleaning of epoxy/stone chip/glass fibre cladding tiles on a tall City Centre office block. The solvent/oil used in the silicone sealant between the tiles had leached into the adjacent tiles causing an irregular dark stain that compromised the clean lines of the cladding. After a few experiments we achieved the results shown below with a very simple and economic lime based poultice. The client has expressed his surprise at the improvement and we are currently awaiting further instructions.

The Steamacc Process and Listed Buildings

WGL Stoneclean Ltd have just been awarded the contract to clean the front elevation, entrance hall and side alley of Retford Town Hall – a Grade II listed building in North Nottinghamshire. We were awarded the contract by Robert Woodhead Ltd of Newark and worked under the site supervision of Jane Harrison M.Sc.CHE. B.A. (Hons). One of the few women site managers in the UK with qualifications in the conservation of listed buildings. So far, only part of the building is visible from underneath the encapsulated scaffold (shown below). Jane says that “WGL Stoneclean have recently carried out works on behalf of Robert Woodhead Ltd, and I found their system of working to be both methodical and professional. Their clear understanding of their profession meant that I was kept updated and informed at all times”.
