The first of these common errors, occurs, and sometimes often underestimated, takes place before the project begins. However, the last few years have seen an unprecedented increase in the demand of the acid staining — books, web sites, videos, and manuals to help designers, architects, and contractors understand the complete acid stain process and products to avert these problems at first place. Testing in a small piece of area is always recommended prior to doing large-scale work. If a contractor notices a character mark by the staining test, using tinted sealers is considered best for hiding these imperfections. Experienced and novice staining professionals covers this type of troubleshooting and touch up work in detail. Dry sanding removed surface effects. The other part of troubleshooting is with surface effects. Surface effect is a catch term given for a comprehensive range of issues, associated with stained concrete. These residues can chemically alter the sealer film as well as act as a bond breaker by clogging the pores of the concrete. Be wary of those contractors propagating staining concrete to be maintenance free. On a positive note, even some badly damaged stained floors can be brought back to life in the right hands of staining professionals. Many times it is not too late to consult a novice staining contractor.
After the chemical reaction is completed, the stains (which are actually metallic oxides) become integral part of the concrete and gives it a beautiful mottled colored surface. The critical element of coloring concrete surfaces with an acid stain or chemical stain is the reaction between the stain and lime in the concrete. Concrete resurfacing with a self leveling concrete or micro topping becomes necessary in the following cases. It will be a very good idea to cover the entire surface with a thin concrete overlay to get desired results. If some tiles are loose or coming off then they should be removed and patched before pouring a self leveling concrete. In many metropolitan cities there is a popular trend of converting old warehouses into lofts. But the existing concrete substrate may not have enough reactive lime for the chemical reaction.
Whip it into shape with concrete stain. The end result is a surface that is a permanently stained and one that will withstand abuse, wear and tear without ill effects. There are some limitations when using acid stains as the colors are restricted to an autumnal palette. But if you want a patio, driveway, floor or any other concrete surface to have a gorgeous long-term splash of color, the acid stain is worth strong consideration. These stains lack the bonding features of the acid stains, but do provide significantly more color choices. If you have decided that you want to get a little more adventurous with your design ideas, use the ample selection of colors to express your creativity to its fullest. Prior to applying the stain, give the surface a complete cleaning with a power washer or a hose and stiff brush. Most home improvement centers sell special applicator devices that will allow you to apply the stain evenly so as to avoid clotting and streaking that can result from the use of mops and squeegees. The main difference in this process has to do with the concrete preparation prior to staining. You’ll need to clean the concrete surface, but in addition, you’ll need to chemically treat it so as to open the pores, which will in turn permit the stain to thoroughly enter the concrete itself. For sure fire quality, look at stains made by Behr, Kemiko and Sherman Williams. If you decide to take go the stain route, you won’t be disappointed. Don’t spend needless time and money replacing a perfectly sound concrete surface. Instead, stain it and transform it for pennies on the dollar.
