Provides a guide to the features and typical characteristics of long-life, aggregate filled, textured coatings intended for exterior or interior use on concrete and masonry, when applied by textured roller, hopper spray or trowel in accordance with the manufacturer's instructions.

This Standard provides a guide to the features and typical characteristics of long-life, aggregate-filled, textured coatings, intended for exterior or interior use on concrete and masonry, when applied by textured roller, hopper spray or trowel in accordance with the manufacturer's instructions.Paints covered by this Standard are classified as paint Type 38 of AS 2311 and correspond generally to Australian Paint Approval Scheme specification Type 4 of GPC-C-117.Aggregate-filled, medium to high profile textured coatings are selected for aesthetic purposes and to provide maximum relief of underlying surface irregularities. The aggregate may consist of sand, marble or other inert mineral constituent. These coatings may be applied by textured roller, hopper spray or trowel, dependent upon the material type selected and the profile required, to achieve a coverage of 0.4-1.2 m2/L (2.5-0.8 L/m2).These coatings are generally specified in a system, including a topcoat as characterized by AS/NZS 4548.2, where maximum resistance to moisture ingress and dirt pick-up is required.These coatings are not intended for use on horizontal surfaces where water ponding is possible. They are normally specified in systems that may have a sealer and multiple coats.NOTES:1 AS/NZS 4548.5 provides a test which may be used to check the cure of concrete and masonry surfaces before applying the sealer.2 Appendix A provides guidance on the use of long-life coatings for concrete and masonry.
