Despite its recent popularity, stained concrete floors are very not really that new. Historically, it started dating back the 1920's when floors were stained to decorate the look of dull concrete surfaces. Concrete staining just isn't like adding some color pigment to wet concrete. Instead, it is finished on cured concrete. Mit reaction of the stain (acid) and the concrete manufactured from rocks and binding cement increases the gray colored concrete a "natural earthy" color.
There's two types of staining concrete floors - acid and water. Most acid stains are a combination of water, hydrochloric acid and acid-soluble metallic salts that really work its way under the concrete surface and reacting chemically with all 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 penetrate easily. Once the stain reacts, the stain now gets a permanent area of the concrete, thus not subjected to fading, chipping or peeling away as time passes. The only real drawback for acid staining is there is not much choice colored - only tans, browns, terra cottas, and soft blue-green to resemble piece of rock, polished marble, stained wood as well as tanned leather.
Similarly, together with the water based staining it's possible to still achieve the same effect but unlike the acid staining, water staining is water coating that bond together with the concrete and, the effects, therefore, is probably not as thorough. Unlike acid staining, newer products like the water-based penetrating stains and water-and-solvent based concrete dyes are actually available for sale with colors ranging from soft pastels to vivid reds, oranges, yellows and purples.
You need to remember though that in picking stain colors:
->> Expect wide color variation, particularly with acid-based stains. This can are more pronounced in the event the final coat of sealer is used.
->> What one sees inside the liquid form will not be what you've got at heart as soon as the chemical reaction involving the stain as well as the cement happens. The true color will only appear when allowed to remain on the concrete for many hours or longer.
->> Along with effect will probably be darker or focused on new concrete than you are on older concrete.
For these particular, it will be best if you apply the stain to a small test area first before applying generally floor.
The thing that makes stained concrete unique isn't two concrete floors, walls or countertops will appear alike but they are addressed with the identical staining product the exact same shade. Factors such as concrete composition and age, porosity, texture and environmental conditions give rise to this uniqueness. Therefore, words like "antiqued", "variegated" or "mottled" all have turned out to be accustomed to describe stained concrete.
The price for staining concrete floors will differ based on the work to be achieved: form of stain, surface preparation, area, and design of sealer to be used among others. Generally, though, given the absolute minimum surface preparation, a simple one-coat application with sealer will definitely cost from 2-4 dollars per sq . ft .. More complicated projects would inside the price to around fifteen dollars per sq . ft . or even more, based on the some time to skill level involved.
