Premier Inn located on Custom House Street in Cardiff is a Grade II listed building built in the mid 1800s. It has recently been transformed into a 248-bedroom hotel and associated bar and block restaurant.

Custom House has been carefully renovated in accordance with the architectural plans, preserving its listed facades and historical elements. The scheme's concept was based on the goal of creating a superior tower that will blend in with Cardiff's ring of towering structures, serve as a backdrop for the historic Custom House building, and revitalise it from street level.

KEIM Soldalit Fixativ was applied onto the newly lime rendered surfaces to equalise surface porosity. A coat of KEIM Soldalit Grob was used to act as a bridging coat on the painted render and to fill hairline cracks to create an even texture throughout. The technical representative, Bryan Roe, of KEIM Mineral Paints recommended the KEIM Soldalit-ME paint system by reason of withstanding the pollution with the added benefit of a long-expected lifespan.
