Shrewsbury Flaxmill Maltings

11 Jun 2024
Case study

Built in 1797, Shrewsbury Flaxmill Maltings based just outside the town centre, was the world's first iron-framed building. It has won the RIBA Regional West Midlands Building of the Year Award 2024.

For almost 100 years, the site operated as a state-of-the art steam powered flax mill, before being converted into maltings and during the Second World War used as temporary military barracks. It closed in 1987 but was bought by Historic England in 2005.

KEIM Mineral Paints were approached by the architects, Feilden Clegg Bradley Studios, in 2017 to help bring this project back to life as a workspace, social enterprise hub and leisure destination. Bryan Roe, Senior Sales Executive of KEIM Mineral Paints visited site and upon inspection found up to 15 layers of paint delaminating from the brickwork. The application of impermeable coatings had contributed to delamination and required removal prior to redecoration. Surface breathability cannot be restored unless impermeable coatings are removed. KEIM Mineral Paints chemically bond to mineral substrates, providing surface protection and UV stable pigment.

The Thermatech superheated water cleaning system was used to remove the existing coatings and ensure full breathability and adhesion of KEIM Paints.

On the brick barrel vaults, the previous coatings were mechanically abraded as the Thermatech system would have been too harsh for the substrate.
