How to Apply Emperor Masonry Paint

Cleaning masonry wall

2. Repair


The surface you are painting must be sound before you can paint it. This is not only to ensure the surface looks its best but also prevents any water getting into the wall so the paint can do its job. If there are any cracks or holes in the wall, make sure you fill these with a good-quality exterior filler. While any loose or defective paint may have been removed during the cleaning process, this is the last opportunity to check whether all previous paint is still sound. If there is any peeling paint, remove this using a paint scraper back to a 'firm edge', where no more paint can be removed.

4. Paint


Make sure to mix your paint thoroughly with a paint paddle before use. The easiest way to apply the paint is a combination of a masonry brush and a long-pile roller, although you can also use an airless spray machine. Emperor Masonry Paint is a two-coat paint which must be applied at 5-6m2 per litre on smooth surfaces, which can be reduced down to 2-3m2 per litre on rough, textured surfaces such as pebbledash. You can dilute your first coat of paint by 10% with water but do not dilute your second coat. While touch dry after 1-2 hours, it is crucial to allow 8 hours at 20°C for the first coat to dry before you apply your second coat. Lower temperatures will extend this drying time.
