Ive just had stencil concrete put down in my back garden. the sealer was put on that evening and the next morning the concrete was covered in white patches about 70% of it. now its terrible looking. what could have caused this and more importantly can it be fixed?

It could be efflourescence, naturally occuring, see detailed description elswhere on this site.

sounds like moisture has been sealed into the surface.the risk of sealing a concrete surface last thing in the day instead of the morning.

post a pic to confirm

i dont know how to post a pic, maybe someone could tell me how?
its not efflouresence, have that on my garden wall (red brick) and that just rubs off like powder. this stuff on concrete doesnt. talked to one of the guys doing it, yesterday, he says its fine it will go after the second coat of sealer
