Cleaning Mildew From Concrete

Surface Gel Teks Gelled Acids are an ideal product for cleaning mildew from concrete surfaces.  They solve significant problem that a typical liquid acid cannot provide. Acid has long been known to be the most effective product for cleaning not only mold and algae but also rust stains and oils from concrete surfaces.

The problem is that liquid acids are very difficult to control. They need to be diluted with water and lack an effective application method. Liquid acid is like trying to work a hammer without a handle.  Gels are to acid what a handle is to a hammer . They make the acid work.

If you have mildew on your concrete surface which has built up over the years on a patio, stairs or sidewalk you can simply pour the gelled acid into a paint tray and roll on the surface just like paint. Let the acids sit for about 15 minutes until they neutralize and wash off the surface.

The acid pulls the mildew, mold and algae out of the concrete and is contained in the gel. The gel works as a carrier. They come in two strengths. HD24 is 24% acid and the HD stands for heavy duty. HD 24 also will profile a sidewalk creating a non slip surface and is very effective as a concrete etching product prior to applying epoxy coatings. The other is Tek Gel for profiling which is 20% acid. Both are ASTM certified .
