Can I leave ECO-Block exposed to ultraviolet rays for extended periods of time?
Exposure of up to a year should not pose a serious problem. However, a light oxidation layer will develop on the surface of the forms after extended periods of exposure. This oxidation does not indicate any detrimental effects to the wall form. However, you may need to use a water spray to clean the oxidized layer prior to brushing the surface with a broom to provide a clean bonding surface.
