Discoloured slabs

[Hogey98]

Alright guys, recently laid some slabs at the back door, nothing fancy. I was told to brush in a dry mix of sand/cement into the joints at the end. Although I though I had brushed it all off it has left damp patches and funny discolouring.

I'm assuming I have not brushed the exess sand/cement off properly. Is there an easy was to fix this or is it simply a case of wire brush and scrub?

Cheers

for me the idea of a garden is variable colour..... so it sounds like you have that?

This is one of the reasons I always wet point. If you use a wet mix and strike the joints before it's dry you know the job has been done right.

Don't use a wire brush on the paving - it may score the surface. Use a stiff scrubbing brush and some hot soapy water.

What type of slabs? If they are concrete you may be able to use some mortar acid on them. Careful though it will wreck some types
