Granite slab poor finish - Sticky looking patches on driveway

[Iron2010]

Hi all

I had grey granite slabs laid in December. We decided to grout despite the temperature to avoid weeds etc. Predictably enough the grout did not set properly and bled all over the slabs leaving a grey film on them.

After talking with the company who I purchased the slabs from I used brick and patio cleaner on the worst affected areas. (The grout had finallly set)

This seemed to go okay but when I applied the sealer I have been left with areas that seem to have a darker sticky looking patch. It's quite similar to the pictures in the thread on the link below but perhaps not as bad probably because Granite is slightly more durable than the sand stone.

However, it certainly isn't the finish that I'm after and i'd be grateful for any solutions.

I used good old fairy liquid and warm water on the area last night (as suggested by a paving company that I called) and it really does seem to have improved the slabs. A blue colour came away which was strange.

It is still far from perfect but my expectations have really been lowered !
