Standard Polished or Decorative Concrete solutions are constantly unfolding. The varying size of aggregate exposure, dyes and stain applications and level of sheen can make your floor something to talk about. Grinding a damaged floor to be sealed or polished as well as filling cracks, chips, holes or gouges will improve the appearance and longevity of your old floor. Add a dye color or design and you have a renewed polished concrete floor that is low maintenance and cost effective!
Prepare the surface with a planetary grinder to open up the concrete pores. Then run multiple passes of successively finer-grit diamond products to create a “profile” of aggregate size, and then apply chemical products like hardeners and densifiers for protection and to get the gloss you want.
The use of a grinder and the appropriate diamond grit will prepare a subfloor for the installation of different types of tile, wood or carpet flooring products. It may also be necessary to remove previous adhesives to prepare for the new flooring. Prepping the floor properly will make installation go easier and look better.
All old adhesives / glues were not created equal. So, when removing it, different glues can require different processes. And, notice that adhesives will have penetrated into the pores, pits, holes, caulk lines, or cracks of the subfloor. Depending on how deep you want to grind will depend on what it takes to remove the glue. When you polish or stain over glue left in these crevices it will take on a different color than your stain.
Basic epoxy flooring can be a simple two-coat application: A penetrating epoxy primer, followed by an epoxy topcoat. More often than not, however, a middle layer made up of epoxy and an aggregate component like graded silica is used to impart extra impact resistance or compressive strength to the floor. This mid-coat is typically followed by an epoxy grout coat, a high performance finish coat or both.
Concrete should be sealed for specific purposes such as stain repellence, dust reduction, abrasion resistance, chemical resistance or to maintain an attractive appearance. It will also strengthen the surface. Concrete is a porous material that readily absorbs liquids. In freeze-thaw climates, the expansion of frozen liquids can destroy the surface of unsealed concrete. Oil, salt, fertilizer, and other household chemicals can discolor and damage unsealed concrete.
