I have laid some raj green honed slabs and rubbed in grey geofix for the joints - it was very hot on the day when we jointed the slabs - so hot you couldnt kneel on the slabs.
its left a dark grease mark around the slab where we have rubbed in the geofix.
any ideas on how to get rid of the marks before i seal he slabs??
apart from the fact that nobody here uses geofix,I would say leave it well alone,the weather will take the marks out over time,along with the geofix !
