Concrete is an interesting substance. It is composed of a mixture of calcium compounds, silica, alumina and iron oxide. To this mix are added limestone, shale and clay. Everything is placed into a kiln which rotates slowly and then heated. A lot of the water and carbon dioxide is removed, leaving what is called clinker. This is then used to produce finely ground cement.
It’s very important to cure the concrete that’s made to harden it and so it becomes durable. Temperature extremes can affect it and if not properly handled at this stage, the concrete can crack. This may be the problem that you are noticing now in your garage and also may be why the surface is absorbing all those oil stains.
Concrete is almost guaranteed to crack as it dries out and if it is not laid perfectly, those cracks can be very uneven and random. Cracks allow all kinds of stains to get through and can be a real problem to clean. It’s at times like these when you start to look for a garage floor cover to cover the problem.
Harsh chemicals may be your answer or even heavy duty processes such as planing, scouring, sandblasting and shot blasting. Do be careful using steel wire though as particles of that wire can come off, rust and stain the concrete in any case.
Substances may be dissolved by using chemicals, but those chemicals can in turn stain the concrete if you’re not careful. There doesn’t seem to be a palatable answer to the problem, unless of course you fit a garage floor cover.
Whenever you try to cover the entire surface of the garage, you have to select the type of paint for epoxy covering carefully. Before that though, the surface must be as clean as possible and you’re advised to use a pressure washer. There again, you need to choose the right type of day and must be sure that it’s relatively dry and clear, otherwise humidity will hang around stubbornly and cause difficulties when you try and set the paint.
The majority of problem areas can be dealt with right now by selecting a purpose made garage floor cover. This is designed to absorb liquids and oil stains before they get to the surface. Polypropylene-based solutions fit underneath each vehicle and will definitely cut down on the amount of time that you might otherwise have to resort to clean up.
When you are designing a new garage and getting ready for concrete, pay particular attention to your process and procedure. Otherwise, it will have a propensity to crack in the wrong places. You can always fall back on an absorbent mat if this happens though, to guard against the likelihood of spill absorption in the future.
