Despite its recent popularity, stained concrete floors are really not too new. Historically, it started way back to the 1920's when floors were stained to spice up the appearance of dull concrete surfaces. Concrete staining isn't like adding some color pigment to wet concrete. Instead, it is done on cured concrete. The chemical reaction of the stain (acid) and the concrete made from rocks and binding cement provides gray colored concrete a "natural earthy" color.
There's 2 types of staining concrete floors - acid and water. Most acid stains can be a combination of water, hydrochloric acid and acid-soluble metallic salts that work well its way underneath the concrete surface and reacting chemically with all the hydrated lime (calcium hydroxide) from the concrete. The acid in the stain lightly scrapes the surface of the concrete allowing the metallic salts to go into easily. When the stain reacts, the stain now gets a permanent part of the concrete, thus not put through fading, chipping or peeling away with time. The only real drawback for acid staining can there be just isn't many options in color - only tans, browns, terra cottas, and soft blue-green to resemble piece of rock, polished marble, stained wood or even tanned leather.

Similarly, together with the water staining you can still reach the same effect but unlike the acid staining, water staining is water coating that bond with all the concrete and, the consequence, therefore, might not be as thorough. Unlike acid staining, newer products such as the water-based penetrating stains and water-and-solvent based concrete dyes are you can find with colors which range from soft pastels to vivid reds, oranges, yellows and purples.
One must keep in mind though that in selecting stain colors:
->> Expect wide color variation, particularly with acid-based stains. This will likely become more pronounced once the final coat of sealer is applied.
->> What one sees inside the liquid form will not be what you've got in mind after the chemical reaction involving the stain along with the cement takes place. The genuine color will still only appear when allowed to remain about the concrete for many hours or longer.
->> Large effect will be darker or concentrated on new concrete than you are on older concrete.
Of those, it might be recommended that you apply the stain with a small test area first before applying generally floor.
The thing that makes stained concrete unique isn't any two concrete floors, walls or countertops will look alike even though they are given the identical staining product of the identical shade. Factors concrete composition and age, porosity, texture and environmental conditions bring about this uniqueness. Consequently, words like "antiqued", "variegated" or "mottled" all have come to be accustomed to describe stained concrete.
The charge for staining concrete floors will differ with regards to the attempt to be performed: form of stain, surface preparation, area, and sort of sealer to be used amongst others. Generally, though, given a minimum surface preparation, an elementary one-coat application with sealer will cost from two to four dollars per sq . ft .. More complicated projects would inside the price about $ 15 per square foot or more, with regards to the some time to ability involved.
