What is cheap? we found that cheap(er) , from a known brand, was just fine. I'm talking about garages with 30+ movements a day, some HGV too, and oil spills etc.. 

I expect there is some rubbish too.

 

which brand/ product would you recommend? 

ive only ever used screwfix own brand or mapei where you mix it with water.

I have no brand name for you, but would only use a known brand name. 

It might be labelled as Garage or Industrial floor paint. 

Own-brand and anonymous stuff can vary in quality and I think the manufacturer also changes acording to the cheapest deal. 

eg I once thought a SF mastic was great value and bought more, which was useless.

I meant leveller. 

i think im going to use a resin top coat.

Can't help sorry. some epoxy paints are very thick, maybe 3mm, but costly

When I have had rain damage to a slab I've ground it down rather than built it up.

a leveller will be much easier.

 

Right then. Done some homework. This looks the business

Sikafloor-440 Level Fibre Reinforced Self Levelling Compound

I can understand why you would grind it down if you had an exact floor height to work too. I'm lucky in that it only needs to be the height of the driveway that isn't going to happen till next year so i can easily build it upwards.

 

i did have a quick look around google last night and saw that sikaflex stuff, guess im pouring £300 on the floor.

Give it a good jetwash to remove the dusty crap.

Two pack floor paint is generally tougher than single pack.

 

If your worried about the stones having sunk to the bottom you could always hack out a foot square sample with a bfo grinder or core drill. You'd need to tip a liquid DPM in before re-concreting.

the only thing to use 

 i used it in my garage biz and most of it was still there 35years later,

 you neeed to sort out the dusty layer ir anything will just stick to the dust  and not the concrete 

maybe a deep penetrating sealer .then the two pack 

your one pack garage floor paints are not brake fluid proof or even some oils   --so thats why we didi not go for the cheap option which would have worked out over the years much more expensive

Not in my experience. our garage clients were perfectly happy with the occasional touch-up and tens of thousands saved (these are 1,000m2 garages).

 

The dealer approved product that was almost as thick as a vinyl sheet was much tougher, but if it was damaged by impact it was a costly repair.

 

So it is over to you.

mine was 750sqm

and was not so thick as to chip easily  

probably what was specified by the franchise --and they never look at things right 

I have had 4 dealerships in my time and they used to spend my money like water if you did not chalenge them

 they would suddenly send you 15k of advertising stands for showroom  -no option and bill your parts accounts 

same with special tools ,at least 90 % of which you would never use ,or in alot cases even know what it is for  or for a model you did not get  in uk

 one maker wanted tiled workshop  floor -they were told to go whistle

 and you wonder why main dealer labouur rates are so high

to be fiar it could have been the floor spec   when we built it 

we wanted same spec floor as they used for heavy earth moving workshop ,so it would not even chip if you hit it with a big hammer

laid then polished for hours with  ,if i remember correctly addition like a resin substance that they polished in to it with the ride on flymo things

I've found that with franchises I built for, so perhaps all do this. They have image people and they have to make changes or what are they for?

There are volumes of information on image.

 

No names here...but one make of cars wanted stupidly flash features for building, and as you say, sent unwanted furniture costing tens of thousands.

But I helped the franchisee talk the manufacturer out of £150k of features. probably costing  treble that now.

On the other hand another brand's design book required the buildings to be 'not too flash', as it gave the wrong impression  on value ,although this was described over several pages of guff, and was subjective.

 

I noticed that Peugeot stuck some wood around the entrances for a few years, to show how green they were, but have now removed it.

 

sorry...floors.

Your point is correct. the manufacturers insisted on the very expensive floors for their franchisees. Non-franchised businesses went for the cheaper and  were happy with the decision.

I assume that magazines and websites aimed at the motor industry will have lots of ads for floor paint.
