Hi all, first post, any advice appreciated :-)
Had a pattern imprint concrete job recently small garden 6 meter square.
Seems OK but has developed white patches, pic attached.
Builder says it is condensation and he will remove with xylene.
Does this seem right?
The desired colour is the reddy one seen in the central "brick" and all the other white seen is undesired.
He says cant do it until early 2016. Should I push for earlier date?
Thanks.
