Is Concrete Resurfacing Necessary Before Acid Staining Concrete?

Chemical stains (acid stains) are water acidic solutions of metallic salts interact with the lime from the concrete. After the chemical reaction is fully gone, the stains (which can be actually metallic oxides) become integral area of the concrete and gives it a beautiful mottled colored surface. The critical element of coloring concrete surfaces by having an acid stain or chemical stain may be the reaction between the stain and lime within the concrete. -stained_concrete-
In many remodeling projects a lot of people want to rip up their carpets, tile and linoleum and think they could acid stain the present concrete substrate and achieve a good looking surface. Unfortunately, it is not that simple. Concrete resurfacing having a self leveling concrete or micro topping becomes necessary in the following cases.
1. Usually underneath the carpet, tack strips are widely-used to hold down it down so when these tack strips are pulled up after removing the carpet, they generate holes in the concrete through the nails used in the tack strips. In the event the holes are patched then stained, they will color differently and stand out like a sore thumb. Applying a skinny micro-topping over the entire surface hides all imperfections and helps to create a brand new canvas to acid stain.
2. Sometimes carpets are glued as a result of the concrete substrate. Get the job done carpet glue is removed, there could be some glue residue left in the pores of the concrete which behaves as a resist or may create unattractive stains on the surface. It will be is sensible to cover the entire surface having a thin concrete overlay to have desired results.
3. If the ceramic, porcelain or quarry tiles are in good condition, it behooves to resurface the tiles with self leveling concrete and staining it with a chemical stain. If some tiles are loose or coming off then they should be removed and patched before pouring a self leveling concrete. Removing tiles and grinding with the tile mastic 's time consuming, messy and expensive. Be resurfacing the present tiles, the project can claim LEED points under decrease in waste and pollution inside the project.
4. In many metropolitan cities there exists a popular trend of converting old warehouses into lofts. Stained concrete is an excellent look for loft floors. Though the existing concrete substrate may possibly not have enough reactive lime for the chemical reaction. In such instances self leveling concrete or micro-topping is the way to -stained_concrete-
5. If the existing concrete surface has paint overspray, permanent ink markings (left by framing contractors), caulk lines, hydraulic oil spills, concrete curing agents and/or flyash, installing the concrete overlay becomes mandatory to get a stained concrete floor.
