weedkiller

[coupe51]

Today I sprayed my block paved drive way with Fast Action Roundup Weedkiller. Thing is the block paving where I have sprayed as all gone WHITE in colour. is this the norm? I've never used weedkiller before now so didn't know what to expect. It doesn't say it cannot be used on block paving so thought I would give it a go.

Any advice is appreciated.

I have never experienced this with weedkiller - although I have not used this particular brand.
I'm sure it is just a residue which can be removed with water and a good scrub!

Maybe it's a "marker" so that you can see that you have sprayed everywhere you wanted to , if it is it will no doubt wash away with the rain.
