Hi all, this has probably been asked a million times but I can't seem to find a definitive answer....
I have laid 27m2 of Kotah Black Indian paving and sealed it with Nexus ProJoint V75. It has been allowed to cure for 3 days now but I got up this morning to see that almost half of it has gone white.
Could anyone point me in the right direction of what may have gone wrong and how I could remedy it before pulling the affected slabs up and replacing them?
