The paper presents preparation of a low shrinkage polyester mortar coating, its physico-mechanical properties and corrosion resistance in various acid media. The coating is made of polyester resin as binder and hollow micropellets in fly ash as powder material. It features extraordinary low shrinkage approaching zero, and low tensile modulus of elasticity. Applied on the surface of portland cement concrete, it forms a resin mortar coating that is highly adhesive, impermeable, waterproof as well as abrasion-, impact-, weathering- and chemical resistant. It has been successfully used in southen China under intense heat of summer when temperature on the ground is as high as 70–80 c as well as temperature of several degrees below zero. It has been used with success as a isolating for large-sized waste acid reservoirs.
