The TIS 469-1983 standard specifies the technical requirements, performance indicators, test methods and application specifications for cementitious coatings. Cementitious coatings are decorative and protective coatings with cement as the main component, which are widely used for decoration and protection of concrete, masonry and other surfaces. The standard details the composition, Color, hiding power, weathering resistance, water resistance, adhesion and other key performance requirements of cementitious coatings, and provides corresponding test methods and construction instructions. Through a unified mass code, the standard provides a reliable basis for the production, inspection and use of cementitious coatings, with the aim of ensuring their decorative, durability and protection under different environmental conditions, meeting the diverse needs of buildings and infrastructure.
