St. Tudor’s Church, Mynyddislwyn, Blackwood


St. Tudor’s Church is a Grade II listed stone church in Mynyddislwyn, Monmouthshire and was built in mid 19th Century.

Bryan Roe, Senior Sales Executive at KEIM Mineral Paints, visited the church and viewed the bell tower which was in poor condition. It was suffering from high contamination of red algae and mould growth.

The limewash lime render was failing and had washed off from the string course due to the exposed location of the tower.

As the building was a lime render, the architect, Morgan Horowskjy, specified KEIM to maintain breathability and durability.

Bryan recommended washing down the surfaces using 50:50 bleach and water to remove the red algae. KEIM Algicid was then used to remove and prevent further mould growth. To offer improved protection, KEIM Silan Primer was applied onto the horizontal surfaces where the limewash had been washed off.

KEIM Royalan was the chosen paint system due to the church being on a hill in a very exposed area.  It will provide durability and breathability for many years to come.
