improving concrete floor surface

floor paint

Most instructions for self levelling compounds say they are not to be used for a final surface and some covering layer is required. That is not to say you will not find one that will do what you want but you will have to sear ch for it all the off the shelf ones will not do. If it's simply a case of stopping the dust, diluted PVA does the trick.

Or diluted SBR which can penetrate better than PVA. Another option might be some thin resin that could be brushed on, or even diluted varnish (not tried this mind!). You want something that will soak in and cure to a hardish finish.

The "industrial" solution to this would be a two pack epoxy paint, which is effective but not cheap. Obviously, if the loads from the "heavy machines on castors" are sufficient to damage the concrete, the epoxy won't protect it.

dusty surface. Is there an easy answer to this problem ? Would self levell ing compound be effective ? It woiuld have to be able to withstand irregula r movement of heavy machines on castors,

There really isn't anything that will withstand wheeled traffic for long. Esp. meatal/hard plastic tyres.
