Tek Gel for Profiling Concrete - Etch and Clean Concrete Surfaces

Tek Gel for Profiling Concrete is a medium-duty gelled acid for removing dirt, organic material, grease/oil, and to profile for thin coatings and overlay applications typically less than 10 mils thick. When used properly, fine sands will be exposed. The treated surfaces will feel and visually look like 120 grit sandpaper.

Tek Gel removes rust, mold, mildew, grease/oil, dirt and much more - profiles and cleans in 1 step.

Ease of use

Roll it on, scrub it in until it stops sizzling, flush expired product to sewer with water.

Tek Gel is a system of gelled acid products that can be used to clean, etch or profile cured concrete before the application of coatings and overlays; as a pretreatment before mechanical grinding; as a pretreatment before acid staining and for Flattooing™ which is the installation of standard and customized stenciled designs and patterns on the concrete’s surface creating one of a kind graphics.

Tek gel can be used on uncolored concrete, integrally colored concrete, color hardeners, and cementitious overlays.

Application

Tek Gel can be applied to horizontal, vertical and overhead surfaces. This is great for removing rust, mold, mildew, grease/oil, organic waste, as well as laitance, efflorescence, surface glaze, release agents and curing compounds from unsealed concrete.

On hard troweled concrete surfaces, the addition of Tek Gel for Profiling Concrete will significantly improve the penetration of stains and dyes, and help obtain the proper profile for mechanical bonding of sealers, coatings and overlays. Used as an initial grinding aid,

Tek Gel can reduce the need for the initial course grinding phases normally done with metal diamond abrasives. Using Tek Gel as a pre-grind can help the overall project budget and is an ideal application for ground, honed or polished concrete.

Tek Gel’s patented formulations are environmentally safe, user-friendly and easy to apply by brush, roller or squeegee. They are ready to use without measuring or diluting. They contain no VOCs, are incombustible and nonvolatile. Clean up and neutralize with water.

Unlike other harsh, liquid chemical cleaners, Tek Gel controls and contains the waste residues for easier clean up and disposal. Tek Gel provides more consistent results and does not damage the concrete by deeply penetrating the concrete substrate, when compared to liquid acid cleaners. Tek Gel does not produce airborne silica dust as does sandblasting or dry grinding. The products are safe for indoor and outdoor use.
