ICO-Primer LV is a low viscosity, two part, 100% solids epoxy primer. It is virtually odorless and non-toxic. ICO Primer LV has excellent damp, as well as dry adhesion to concrete, masonry surfaces, wood and gyp board. (For priming metal, we recommend our Rust Guard Coating). With a very low viscosity of 250 centipoise, it readily penetrates porous substrates to provide an excellent mechanical bond. Such a highly penetrating primer has also been found effective in sealing the concrete to help prevent outgassing. Where faster curing times are required, specify ICO Primer LV FC. For application between 320°F and 500°F, our ICO Primer XFC material should be used. For vertical surfaces, our ICO Primer XT is preferred.
