What is this white stuff appearing both on house brick and block paving?

Postby apacheDIYman » Fri Jun 11, 2021 8:34 pm

I've started seeing this white stuff appearing both on house brick and block paving.

At first I thought its because of sealing the block paving but its also on my house brickwork which it wasn't before.

Is it possible to remove it? What is the best way to clean bricks like this?

Hi apachediyman
You could try acid brick cleaner but it looks like water is coming out over your DPC so this may be an ongoing issue.
