Are you considering enhancing the look of your existing concrete? If so, you might be thinking about acid stained concrete. Acid stained floors have become increasingly popular, especially in high-end designs. Acid concrete stains contain hydrochloric acid, which work to open the slab’s pores, giving the metallic salts contained within the stain the ability to react with the lime present in the cement. The corresponding chemical reaction is responsible for creating the color variations associated with acid stain.
Before deciding whether acid stained floors are the right choice for your home or business, it’s a good idea to understand a few facts about acid stained concrete. Acid staining is typically, but not always, performed on existing concrete floors. This means that if you have an older concrete floor that has seen better days and may even have some flaws, acid stained concrete could be a good way to enhance the look of your flooring without the need to rip it up and have new concrete poured. However, on the other hand, all of the imperfections of the old slab may be enhanced with the reaction of the acid stain, so if the imperfections are too much, you may opt for resurfacing the surface first with a thin polymer modified concrete material, and then apply the acid stain.
One of the most common problems we see is that many people try to handle their own acid stained concrete in New York. Although home improvement stores do sell acid stains, most people simply do not have the experience to work with stains and create a professional quality design.
For instance, we may need to grind your concrete slab before performing the acid staining. Grinding your slab will help remove any curing compounds that may be present and result in a better finished product. If the curing compounds are not properly removed from your existing concrete slab, the remaining spots will usually accept the stain in a different manner. This could result in yellow or white spots. If you have new concrete, it will need to be properly cured before starting the acid staining process to ensure the best possible results.
