white walls? All manner of questions and solutions to problems and issues surrounding the subject of brickwork, blockwork and stonework

[marty c]

I have recently built a new garden wall but when it is dry it is covered in what looks like white salt marks all over it spoiling its new appearance. I have tried a high pressure water jet to remove it but to no avail. Any tips would be appreciated, thanks Marty C

Use brick acid, available from builder's yards.
It's only the salts in the morter coming out.
