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?

Not being awkward, but why?

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.

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.

As above.
