Masonry paint

Masonry paint and other finishes to masonry

Our surveyors find that masonry paint has been used prolifically in places like London and York. It is often used on older buildings that have been rendered, including rows of Edwardian townhouses in London and traditional timber framed buildings in York. This may not be an issue if it is used on masonry that is likely to remain dry, but any dampness within the building can cause the paint to blister as well as the masonry to perish. It is not always possible for a surveyor to identify the type of paint that has been used, but mineral paint can also be acceptable as this allows the masonry to breathe. However, impervious masonry paint (including that described as ‘microporous’) can cause these issues to occur. If the wrong type of paint has been used, it can sometimes be necessary to remove all of the paint, before repainting using mineral paint.

Masonry paint can also be used on stucco or stone dressings and is sometimes directly applied to brickwork and in these places it can also be an issue. A surveyor may need to recommend further investigation or that advice is obtained from a specialist in either external rendering or external decoration, so that it is possible to quantify the cost of any necessary remedial work.

The render itself can also be an issue depending on the type of material that has been used and if problems exist, it may become necessary to remove the render so that the appropriate finish can be applied.
