The popularity for limewash or Venetian plaster aesthetics is increasing, but as watered-down acrylic paint mixed with bicarbonate of soda isn’t vapour permeable and can contain solvents, we've developed KEIM Colourwash - an interior mineral paint to replicate historic finishes which is  non-caustic in composition and non-chalky in finish.

In addition to the high quality associated with KEIM Mineral Paints, KEIM Colourwash is #likelimewashbutbetter, uses UV stable pigment and supplied ready for use, making it ideal to apply onto both bare and previously painted walls and ceilings.

Following the launch of KEIM Colourwash in April 2023, we’ve been searching for collaboration projects to showcase the easiest way to achieve a limewash aesthetic without the hassle of limewash.

Nathalie Mackinnon (AKA Nat the Painter), already experienced with the application of KEIM Mineral Paints for projects including St Andrew’s by the Wardrobe, put forward KEIM Colourwash for Waterloo wine bar, Café Del Marsh.

Soft and cosy Colourwash KNIT was chosen to compliment the Parisian-influenced interior of the contemporary café and live music venue, paired with Farrow & Ball Wimborne White for the wooden panelling. Sol-silicate Colourwash BASE is suitable for direct application onto previously painted surfaces and creates the perfect opaque white base to create depth to Colourwash shades.

Nathalie rocketed through the paint application (you can follow the Café del Marsh decoration journey on Instagram: @natthepainter or @keimcolourwash), applying a single coat of Colourwash BASE followed by one coat of Colourwash KNIT with 12 hours between coats. Nathalie commented “I love the finish. Colourwash goes on like a dream”.

The Colourwash system comprises: Colourwash BASE – a one-coat opaque white paint suitable for bare and previously painted walls and ceilings, and Colourwash in five complimentary colour shades, curated by KEIM’s Creative Finishes Designer, Amie Paxton. Optional surface texture to mimic historic limewash can be created using Textured Undercoat, with bare or new lime plaster surfaces requiring a coat of Lime Primer. Application is best with a KEIM Oval Brush.

In addition to the standard colour range, a bespoke colour design service is available. Whether you want interiors reminiscent of charming Italian architecttura, sundrenched Morroccan riads or are inspired by chic Café del Marsh, we’re here to help you achieve your creative vision in as little as two coats of paint (no art degree necessary).
