PMAC specialise in Facade cleaning

PMAC recently undertook a project for a private client to restore the red brick facade at a house on Marlborough Road, Dublin.

Our brief was to clean and restore the front facade of the house, including repairs and re-pointing of the facade and chimneys.

Cleaning a brick facade

We cleaned the red brick front facade of the house, by pre-washing the surface using a mild detergent. Once complete, we used a specialised heavy-duty restoration cleaner, combined with low-pressure hot water. The cleaning included the chimneys and granite sills at the rear of the building.

Restoring the brick pointing

Following cleaning, the existing pointing was raked out to a minimum of 15 cm. All re-pointing was carried out using traditional methods and using lime mortar supplied by The Traditional Lime Company in Carlow. Window surrounds at garden level were pointed using traditional wigging pointing. Every project needs to be explored to find out what pointing style is required for each elevation.

Bricks that needed to be replaced were sourced from salvage yards to get as close a match as possible taking into account age and colour. Brick repair mortar was supplied by Contec (Conservation Technology) and was colour-matched by Remmers.

At basement level, we applied both traditional, slightly recessed flush pointing with a lime mortar and wig pointing. The three chimneys were cleaned in the same way as the brickwork, raked out and slightly recessed flush pointed.
