A bit of background first;
We had 50sqm of mid-grey granite slabs installed late last year - just before the weather went really wet. So now the sun has bothered to turn up, I wanted to get around to sealing them.
I’d specified VDW 815 Plus for the 3mm jointing, but when applying, the four lots of 10kg seemed to disappear under the slabs, so it covered about 10sqm. I wintered the joints with paving sand to stop ingress of seeds etc and was looking to seal with Adseal Stone and Slate Protector. APART from the internal argument to somehow get the granite looking darker (wet look without the wet-look), it seems that when applying the VDW, there are some dark blotches left behind on some of the edges. I believe these may be from underwetting the granite during application, and lack of efficient cleaning off of the residue afterwards...
So, is there a way to remove this darker blotching - a resin cleaner?. I didn’t want to seal it in with the sealant. Or would it be necessary to replace the slabs? Or, would the slight darkening due to the sealant, possibly hide the resin...
Thanks for your thoughts.
