Industrial concrete floor question
Maybe a bit of a weird question to ask, because you need to know what image I've got in my head, but here goes
See the floors you get in industrial workshops, looks like concrete, but is really smooth, hard, and polished, what is it? Is it just polished
concrete?
I'm having a major clear out of the garage to make way for the possibility of a trailer, and more importantly, a set of gojak type wheel skates,
and a heavy steel workbench on castors I'm intending to build soon, and my garage floor is a nasty soft rough poor type of concrete floor, the
type you can sweep all the dust off of, sweep it again and its just as dusty. Not really any good for taking engines apart, or spray painting, for
example.
The floor has been painted many years ago with garage floor paint which helped a bit but its time to do again.
Looking for something to give similar results to the floors I've seen before, in both hardness, non dustiness, and smoothness. Are they some
sort of resin to look like concrete maybe? Epoxy perhaps?

Yup. Just polished concrete. My mate made kitchen worktops out of coloured concrete and polished the finish to a shine! Perfect for working pastry on
apparently.

Interesting! I had seen concrete worktops being done on tv, never really thought about it, but I guess with some interesting aggregates in there,
probably looks every bit as good as granite?
I always assumed the floors were epoxy made to look like concrete.
Thoughts on the best type of paint/coverings then? 2 part epoxy paint? The floor is dusty soft concrete, so needs to not break up and lift. Like I
said there is paint down already, will that do as a primer?

Polished concrete is the process used when laying the floor. I used epoxy paint on my new floor and it has worked well, it cost about £50 for as 5ltr
tin. However, the paint finish is only as good as the surface it is on. If yours is breaking up then you could consider cleaning off the surface of
loose bits a good stiff brush and sealing with PVA bonding befor applying a screed if possible. After that apply a decorative finish.

you can grind back set concrete to give a polished finish (with fancy aggregates and sometimes with epoxy) - I can't remember the name for this
but its been making a bit of a comeback on the likes of grand designs etc....
but in this country most folk would polish it as it sets - often with one of these:

you do get fancy hard wearing screeds with high impact toughness designed for workshop floors, the ones I've seen were meant to be poured about
1" thick - but they aren't cheap !
In the end I did a couple of coats of PVA (diluted in water) then just normal floor paint - its worked pretty well considering some of my floor was a
month old and other bits were 80+ years old....

My garage floor was the same
White dust everywhere no matter how much i swept and mopped
I pva'd mine - then garage floor paint
Swept and vac'd,then cheapo pva watered down and roller on
2 coats and it sealed it
I used it like that for a few weeks as the weather had turned and no dust or mess , oil spots wiped up etc
When i painted it went on really well and still looks perfect

There are no short cuts that last very long to get a good durable finish that your after assuming the surface is already contaminated with oils and
other fluids.
As you said it is a soft surface also you would be looking at scabbling the entire floor back to virgin good concrete then applying one of the many
self leveling epoxy screeds or grout's on the market.

No, the floor is pretty clean of oils and stuff. Its actually in not bad condition, not cracked, or breaking up, just dusty
Not looking to take shortcuts, but obviously I'm not taking the floor up to lay a new one, polish it, paint it with the top quality coverings,
spending thousands on a garage floor, just want a decent hard covering that doesn't kick up dust, and allows the engine crane, jack, and skates
to move around easy. Its kinda ripples slightly, only by less than 5mm I guess, if something can be poured to help fill this in a bit, perfect
This looks good

Hi Blake,
In my experience with industrial workshop floors they're made of fine concrete with a polished finish. When done well they're not cheap,
but very durable with a good layer or few of paint applied.
For a home garage IMHO it's over the top in terms of cost, preparation and complexity. I'd opt for decent poured concrete with a good
layer or 3 of paint. Should be possible to get it flat enough for good vehicle setup as well.
Hope that helps.
Nick

Its polishable concrete
Hi there are few options to achieve glossy finish on the concrete floor. Use polishable concrete now often used to make kitchen worktops other option
is spray painting the floor with clear epoxy.

When specifying the floor in a garage built for me during a previous life, the builders understood the requirements. They spread the concrete floor
carefully and then went over it (when starting to set off), with a huge rotary trowelling thingy. The result was a dark grey highly polished flat
surface. Later on, I did try to paint it (I'm not a fan of grey), but it came straight off the surface, completely, with a vacuum cleaner. I
gave up on that idea. Anyway, fantastic surface.
The garage/workshop in my current life had a variable floor. Sound dusty concrete one end, marginally cemented material at the other. Builders came
in, dug the lot up, laid down several inches of 'MOT', damp proof membrane, several inches of concrete, a layer of weldmesh, and then
several inches of screed with some polythene hair intermixed. Not what they 'usually do' in garages I was told.
Although unpolished, it's flat enough to build a chassis on, set a car up, and strong enough to take the usual abuse without detriment. It also
took to polyurethane paint, ideal. I love it.
I've sealed a dusty garage concrete floor with solvent-based PU paint in the past, with PU paint on top, renewed every couple of years.
I'm guessing this is all you'll need. I looked at epoxy, decided this was too expensive, required too much careful preparation on a very
sound etched surface. It also needed temperatures to set off that this grey damp rock struggles to produce. I also errrr'd over it's
durability.
