Cleaning Brickwork prior to applying Stormdry

[John74813]

Hi

Can I get some advice please - I've had some work done on the front of my house to fix an issue with water ingress. I now need to paint it with Stormdry (Water repellent). I have two questions I would appreciate your advice on please:

1. What can I clean the blackened brickwork with? I've tried Spear and Jackson spray and leave but it doesn't seem to have done anything.
2. Is there anything I can do to make the new bricks/pointing blend in better? Or will it do so over time?

Thanks in advance
J

You need a nylon brush and cleaner.
Something like.

Thanks Wayners, that will clean up my old bricks/mortar? I think they are blackened because it's so exposed and they're constantly wet when it's raining

Just need to clean the best you can then treat.
You can hire a jet wash or get a company in but you need to be careful not to damage bricks.

Can’t think of any good reason to apply stormdry to brickwork , needs to be able to breath to avoid damp .
