ASTM C811-98 (R2008) PDF Download

ASTM C811-98 (R2008) is a standard practice that provides guidelines for the preparation of concrete surfaces to receive chemical-resistant resin monolithic surfacings. The term "monolithic surfacings" refers to toppings that are applied over concrete with a thickness of at least 60 mils (1.5 mm) and cure in place, providing a continuous surfacing that is bonded to the concrete surface.

The surfacings are composed of fillers, resins, and hardeners that, when mixed, applied, and cured correctly, form a strong bond with primed or unprimed concrete. These monolithic surfacings can be either reinforced or unreinforced.

The standard practice does not restrict the method of application, allowing flexibility in how the surfacings are applied to the concrete. It is important to note that this practice is specifically designed for use with filled resin systems, such as those specified in ASTM Specification C722, and does not replace or supersede the manufacturer's instructions for specific products.
