This week I've been preparing the garage floor. The concrete has been down for about 7 months now and is unsealed so it's really dusty. My original plan was to polish it and clear coat it, but I think it will be too dark in colour so I have decided that I will use a 2 pack epoxy paint on it.
This however doesn't let me off with grinding it down to remove the latience (fine particles of cement floated to the surface during finishing) (the list of things I've learned with this project is getting longer by the day) which was causing most of the dust and was starting to break up and leave pitting and more dust. On Monday I hired an electric carborundum grinder and made a start, The top layer came off easily and as long as I swept up often there wasn't too much mess.
On Tuesday I hired a concrete planer to get into the edges, it looks like an angle grinder with a sole plate and has a cupped diamond tipped blade. This was the monster from hell, the dust was everywhere, thick to the point it choked my mask and I had to vacate the garage on several occasions just to breath, not a nice job.
On Wednesday I started on the floor again, using medium carborundum stones and I have to say that this will be as smooth as I will be going as the 2 pack epoxy paint will need something to adhere to. I am just at the stage where the aggregate is starting to polish up. The edges and corners still have to be finished off by hand and for this I will use the carborundum stones to tidy it up.
Here are a few pictures I took on Wednesday
I knew the ramp would come in handy
This is the aggregate showing through.
and outside on Wednesday
I called a few companied who do concrete floors and was quoted £1500-£3000 for the work, depending on what was involved and I will hazard a guess it would be nearer £3k.
Doing it myself for the cost of hiring the equipment and the 2 pack epoxy undercoat and top coats it will cost me less than £600, so quite a saving. I have to say though, it's a heck of a lot harder to do than I ever imagined.
On Thursday I finished grinding the floor. Edges and corners tidied up by hand using a medium stone and the floor has been hosed down to remove the dust. Now I need to wait on it drying out and also for some slightly warmer weather before applying the epoxy coating
