BuildCrete Stucco

Item: 00-BC-STUCCO

Description

Description

BuildCrete Stucco is a true one-coat stucco designed to adhere directly to any EPS foam, CMU block, DensGlass, Securock, concrete and other building materials. BuildCrete has been used on ICF construction for its durability, strength, and ease of application. It allows contractors to be green without complexity, compromising performance,or high cost.

BuildCrete Stucco exterior wall finish coating performs beyond any conventional exterior stucco on the market today and features: excellent water resistance, impact and abrasion resistance and resistance to mold and mildew.

It is the perfect choice for exterior applications including as a bonding agent and mortar for manufactured (cultured) stone facings. The 3/16” one coat application has over 3,500 PSI compressive strength. BuildCrete™ is designed to be environmentally responsible, utilizing natural limestone sand and zero portland type cements. It is sustainable and emits no pollutants.

Each 75 lb. (34 kg) of BuildCrete Stucco covers approximately 42 sq. ft. (3.9 m2) at a thickness of 3/16 in (4.8 mm).
