Spring cleaning extends outdoors, and the garden wall usually reveals moss and mould in the most unlikely places - unsightly, and worse, holding moisture against the masonry. Preventing or removing it is not easy. Here is how one perimeter wall was cleaned and protected - and the striking difference between the treated and untreated halves.
Step one: clean
Pressure-wash the surface at high pressure to remove every trace of dirt, mould and moss.
Step two: dry
Let the surface dry completely for at least two to three days - so do this in spring or summer, with the first warm weather.
Step three: one coat of Brickcover
Spray Brickcover with a low-pressure pump - a single coat is enough. It can also be rolled or brushed, avoiding pooling.
Brickcover is a ready-to-use, water-repellent anti-degradation protective for stone, brick and concrete. It penetrates deep and leaves the surface completely natural, without changing its colour. Non-toxic, film-free and fully breathable, it makes the material impermeable to water and protected from the weather; its potassium-salt formulation gives a very long-lasting treatment.
One precaution: cover any glass or steel nearby - the product is alkaline and could dull those surfaces.
Simple to apply, effective, ecological and long-lasting - see Brickcover in the UK range.
