Mode of Operation
ETCHEX will remove most metallic stains such as rust depending the stains origin. When used in conjunction with GELTEKK it will open surface pores so that the GELTEKK can deep clean and effervesce the pore compound out of the pore space. This is a 10% solution of sulfuric acid that is safe but still works like acid.
ETCHEX is designed to be chemically reactive to alkaline materials to chemically react opening the profile of such surfaces. When used with GELTEKK the ETCHEX will effervesce materials out of the pores and neutralize the acidic activity.
ETCHEX has minimum odor and off gassing.
Types Of Surfaces
ETCHEX can be used on various types of surfaces where chemical etching may be needed such as concrete, masonry and stone. When used in conjunction with GELTEKK the acid will effervesce lifting soils from the GELTEKK and neutralizing the acid.
Once rate of dilution is determined and the expect ed results are achieved, apply the material to the surface with brush roller or spray. Spray application with low pressure bug sprayer type applicator, generally provides the most uniform application method.
Note: As with all chemicals, always wear appropriate protection in compliance with general chemical application procedures using OSHA approved type protection. Always read the attached MSDS for all safety precautions and concerns.
