Despite its recent popularity, stained concrete floors are very not new. Historically, it started way back to the 1920's when floors were stained to decorate the design of dull concrete surfaces. Concrete staining isn't like adding some color pigment to wet concrete. Instead, it is finished on cured concrete. Caffeine reaction of the stain (acid) and the concrete made of rocks and binding cement gives the gray colored concrete a "natural earthy" color.
There's 2 kinds of staining concrete floors - acid and water. Most acid stains really are a blend of water, hydrochloric acid and acid-soluble metallic salts that work its way below the concrete surface and reacting chemically using the hydrated lime (calcium hydroxide) in the concrete. The acid inside the stain lightly scrapes the top of the concrete allowing the metallic salts to go into easily. After the stain reacts, the stain now turns into a permanent part of the concrete, thus not put through fading, chipping or peeling away eventually. The only real drawback for acid staining is there is just not much choice in color - only tans, browns, terra cottas, and soft blue-green to resemble stone, polished marble, stained wood or perhaps tanned leather.
Similarly, using the water staining you can still reach the same effect but unlike the acid staining, water staining is water coating that bond with the concrete and, the result, therefore, may not be as thorough. Unlike acid staining, newer products like the water-based penetrating stains and water-and-solvent based concrete dyes are now you can find with colors which range from soft pastels to vivid reds, oranges, yellows and purples.
You must keep in mind though that in picking stain colors:
->> Expect wide color variation, particularly with acid-based stains. This may are more pronounced if the final coat of sealer is applied.
->> What one sees in the liquid form will not be what you have in mind when the chemical reaction between your stain along with the cement takes place. The real color will only appear when allowed to remain on the concrete for a lot of hours or longer.
->> The color effect will be darker or concentrated on new concrete compared to older concrete.
Due to these, it will be a good idea to make use of the stain with a small test area first before applying overall floor.
The thing that makes stained concrete unique is no two concrete floors, walls or countertops can look alike while they are treated with the identical staining product of the identical shade. Factors such as concrete composition and age, porosity, texture and environmental conditions give rise to this uniqueness. As such, words like "antiqued", "variegated" or "mottled" have the ability to become used to describe stained concrete.
The fee for staining concrete floors will differ depending on the make an effort to be achieved: kind of stain, surface preparation, area, and design of sealer for use among others. Generally, though, given a nominal amount surface preparation, a simple one-coat application with sealer will definitely cost from two to four dollars per square feet. More technical projects would in the price about $ 15 per sq . ft . or maybe more, with regards to the some time to level of skill involved.
