Hypo and soft bricks

[Aquajetexteriorcleaning]

I've got a customer that's wants her walls on the house cleaned, they are soft bricks soaks up water like a sponge, is it ok to use hypo? If so what mix would you use? The walls are green.

Sounds like a test patch is needed

Yes I think so, just not sure weather to really soak them first before putting hypo on.

Yep sounds right

You could try both wet and dry on the test patch
