Staining Concrete - Green, blue and beautiful!
Concrete floors are hardly a new phenomenon, many of us will have an old lumpy piece of concrete flooring or patio somewhere around the home! One of the most common questions that builders and concrete professionals get asked is "how do I make my concrete ______ look better?"। For some time now builders and designers have been espousing the virtues of decorated or painted concretes. The most recent development, although hardly new, is concrete staining.
What you will want to know however is what are the advantages of staining concrete flooring, compared to the large number of options available to everyone nowadays? Hopefully I can give you some help here!
Why concrete staining?
Many people wonder why you would bother to stain concrete when there are so many other options open to you in terms of flooring. Tiles, wood floor, laminates, or even painting direct on to concrete are other options that maybe cheap, and simple to do. If you ask any professional they will probably give you a single word answer! "Character".
Stained concrete has a feel of rich, deep, translucent tones, similar to that find in fine oil painting, this means that the floor looks like it has aged into the site, rather than being a feature due to its newness। The results can mimic metal, marble, stone and wood, and because the effect is dependent on the underlying concrete, no two sites are ever the same.
Concrete is environmentally friendly in comparison to many other forms of flooring। Hardwood obviously has all the issues relating to sustainability, laminate floors are notorious for non-green production processes, carpet production is very environmentally unfriendly, so concrete is a relatively green process.
How is it done?
There are now two ways to stain concrete, one uses a weak acidic solution, and the other uses a pigment based solution. Each type has its advantages and disadvantages.
In the first category are chemical stains, these in effect do not have any color of their own, but color the concrete using a chemical reaction। The acid reacts with the lime deposits, and imparts the mineral agents into the concrete. This color is formed as a permanent bond and will not chip or peel away. The best finishes are achieved with acid staining, as the depth of translucency is achieved by the use of multiple layers of color and finishes.
The second category is the water based acrylic pigment solutions. These soak directly into the concrete and leave behind their pigment. These are preferred by many as there is a much wider choice of colors, than can be found in the acid stains. However they do not last as well, and certainly don't produce the same depth of color.
The most conventional way to apply a concrete stain is to place multiple thin coats onto the concrete, most professionals would use some form of spraying equipment. Be warned that the effects you achieve will vary with the quality and condition of the concrete. Concrete staining will only work where the stain can penetrate the substrate. An easy test for this is to pour a cupful of water on your slab of concrete and see if it will soak, if the water beads or wont penetrate, then the stain will not take either. If this is the case, then your other option is to apply a cement layer over your slab, this will give you a nice clean surface.
