Beginning with rebar corrosion inhibitors and primers, we offer repair mortars and injection grouts, surface finishes, water repellents, mineral silicate systems and a variety of architectural coatings. Our systems are designed for the specific tensile and compressive characteristics of your substrate. Best of all, our Matrix repair system allows contractors to color match our mortar to your substrate on site. Stone isn't uniform in color. Subtle shade differences are the hallmark of stone facades. With Matrix, you have an entire palette of color at your fingertips. Conproco also offers custom color matching, exterior wall systems and our own line of ProMasonry brand pre-mix products.
