Bricklaying & Repointing

MOSS ON BRICKS that have been stored outside in a rural area

Anonymous user 23/02/2024 - 3.21 PM

I have about 2000 bricks which were new and surplus when i built my bungalow. I now wish to use these to build a garden wall but they have got covered in moss and algae of varying degrees. I need to remove the moss and I`ve tried soaking some in bleach and purchased (supposedly 100% successful ) moss killers off e-bay which have been totally useless. I`ve tried brick (acid) cleaner and even put a few in a ``bath`` of caustic acid but without any real success. Has anyone any serious recommendations. Apparently jet washing the bricks isn`t recommended by some as the power wash system drives the moss spores further into the bricks. With thanks for any serious suggestions on how to clean these bricks.

Are you a tradesperson and able to answer this question?

Moss & Algae Will Be Because The Bricks Are Still Wet/Damp.. Jet Wash It Off & Leave In A Dry Place.. Any Come Back Scrape It Off Whilst It’s Dry.. Hope This Helps..

You can use a domestic power washer to clean them up, and once any brickwork is built you can use brick acid to take any blemishes or weathering off the brick to bring it back to a fully clean state

The moss and algae is there because the bricks are wet. Put them somewhere warm and dry and moss will die and fall off, then you can brush with a medium hard bristle brush and clean them
