One of the easiest ways of refreshing the outside of your home is by giving it a new lick of paint. Exterior paint or masonry paint, will be the best option to paint your exterior walls.

Does masonry paint need an undercoat?

The vast majority of trade masonry paints do not require an undercoat. However, for chalky and flaky external walls, it is recommended to use a stabilising primer, such as Farrow & Ball Stabilising Primer, or a stabilising solution, such as Sandtex Trade Stabilising Solution. These will seal and stabilise external walls to prepare the surface for an even and longer-lasting finish.

Can masonry paint be used on internal walls?

You should not paint internal walls with masonry paint. Masonry paint will have different chemical compounds than interior paint as these are formulated for outdoor use. They often contain fungicides to inhibit mould growth which are not necessary for internal environments. Exterior paint can also give off powerful (and sometimes dangerous) odours in confined spaces.

The drying time of masonry paint will depend on the paint used. For instance, Sandtex Trade High Cover Smooth Masonry Paint will be touch dry in 1-2 hours whilst Armstead Trade Smooth Masonry Paint will take 4 hours to be dry even though it is shower-resistant in 30 minutes. Another deciding factor in drying time is whether oil-based or water-based masonry paint has been used.
