Are you a contractor looking to diversify into other service offerings? Concrete maintenance and restoration; including cleaning, prepping, polishing, and staining, might be what you're looking for.
Nothing can last forever. That includes what might be thought of as bulletproof, concrete floors. Even concrete floors will wear, crack, and especially, stain. Fortunately, you can fix almost any surface, and concrete is no exception. It starts with a process simply called “surface preparation.”
When we talk about surface or floor preparation, we’re referring to the act of removing oil build-up, thin-set or mastic, old floor material, acid-based stains, or other contaminants, and then prepping the surface for a new coating, polishing, or new type of flooring. Surface preparation fulfills two distinct functions: first, you are scraping away or grinding off the old stuff, and second, proper preparation will ensure the surface is ready for a new “surface profile.”
There is a wide range of methods used to prepare a floor or surface, but of all the options, the most common are lumped into two categories: chemical and mechanical.
Chemicals are often used to remove thin-set or mastic from concrete surfaces. Aramsco carries a wide range of mastic removers. After using a mastic remover, which is often solvent-based, you'll need to remove the mastic remover that is left behind. A good detergent-based wash on the alkaline side (pH above 7) will get rid of any remaining solvent residue. The next chemical used depends on what you're trying to accomplish, but if you need to prep the surface to lay down an adhesive, it's common to use an acid cleaner to etch the surface.
Mechanical floor prep offers a variety of options, but you’ll have to determine what’s best depending on the area size, surface material, and use. If you’re unsure which piece of equipment is right for your job, here are some ways to do it:
Safety is paramount. And unwanted contaminants can interfere with a surface’s adhesion. In essence, you want to remove loose particles and pieces of the floor that prevent bonding, which can lead to trips, falls, slips, and stumbles.
Furthermore, a well-prepared floor is aesthetically pleasing. Proper preparation results in glossy, polished surfaces that look nice and feel smooth and comfortable to walk or drive on.
Be mindful of the weather and humidity. Moisture can influence the efficacy of the job, particularly on outdoor surfaces.
Scarifying, milling, or grinding equipment, as well as acid etching, cut small grooves in the subsurface. These grooves resemble minuscule peaks and valleys that help the top layer grip the foundation. Remember, if the top layer is laid too deep into the valleys, the peaks will protrude through the surface. A general rule of thumb calls for a third of the floor material to be above the “peaks.”
