The Plaster Bond treatment from building materials specialist, Magply, has been employed as part of the specification for the renovation and conversion of an old agricultural building at a property in Essex.
The 200 year old single-storey building has been transformed into office accommodation by a local building company, lining the rustic timber and stone construction throughout using the manufacturer’s high performance Magply MGO boards to create a sound and level surface. The fire resistant, highly moisture stable boards were then given a roller applied coating of the new mineral based Magply Plaster Bond, prior to being finished with a conventional one-coat gypsum skim. The versatile new primer has a potassium silicate formulation suitable for most common building substrates and can be applied by brush or roller to create an even, but slightly gritty surface offering a strong mechanical key for a range of plaster types, including lime based finishes.
The owner of the property commented: “While the timber trusses and general structure to the barn were in reasonably good condition, the walls were very irregular and we also wanted to conceal the underside of the roof coverings, so our architect selected the well-proven Magply MGO boards to provide a flat and stable, fire resistant lining and although the 9mm boards are routinely used as a substrate for render treatments or tiling, when the company’s technical department heard we wanted to create a crisp plaster finish, they suggested applying a coat of the Magply Plaster Bond.”
Not only were the boards easy to cut to shape and fix, but the bond coat was very straightforward to apply and gave our builder extra confidence in plastering the interior.”
Independently tested by Sheffield Hallam University and PRA Coatings for vapour diffusion, Magply Plaster Bond is therefore proven not to trap water vapour within the fabric of a building. Additionally, the potassium silicate based primer coat is VOC free and odourless and contains no other co-binders such as solvents, gypsum or cement, making it non-hazardous. Applied by broad brush or roller using short strokes, the product gives a coverage rate of approximately 500g/m2 or some 35m2 from one of the 17 kg recyclable containers. Appropriate vapour open plasters can then be applied at any point after a 24 hour curing period.
