Skimming Concrete
Hi
Rob Morley gave me the idea of stripping the surface of my concrete drive with a scabbler and skimming it. This looks a workable idea, so; How thick is the skim and what sort of mix? Do I lay it just like concrete between formwork? Do I need a bonding agent? Dave |

This looks a workable idea, so; How thick is the skim and what sort of mix? 3:1 sand/cement with about 6:1 PVA/water, prime the surface with the PVA mix and allow to dry first. 1" minimum and cover with 500 gauge polythene for a week or so to retain water. Do I lay it just like concrete between formwork? Better to install a couple of screeds (wooden rails) on stakes either side. Pour in the mix, and use a third piece of timber across them to shuffle along the job to get your flat surface As it is a driveway the slightly rough surface will be a boon on frosty mornings. You may of course finish the surface with a float. Do I need a bonding agent? As above. John Schmitt |
