Anyone with experience of this? the concrete in my cubicle shed is very slippery and i need to sort it before winter, was thinking of grooving as the most obvious way to go and wondered if it actually worked or whether there were draw backs with it?Now I know it's a long time ago but our 130 Fresians soon polished a slab of concrete to the inevitable mirror smooth. Great for scraping out but yes they still slipped occasionally going round the corners.
I did however mull this over @RWG Contracts and how about scrabbling in lines as if you were mowing with a Dennis?
See the result of your efforts the following polished concrete st louis year and then perhaps go accross the opposite way. Me I'd still be concerned about removing too much of the top layer hence the caution.
One good frosty winter may wreck the scrabbled area and thus the yard as ice is a powerful force to be up against.
