573 Fastfill Screed is a single component, polymer modified cementitious coating developed for rapid resurfacing and internal waterproofing of concrete. Formulated with advanced micro-silica, fibre, and polymer additives, it cures to form a dense, durable matrix capable of withstanding up to 10 bar (145 psi) of negative hydrostatic pressure.
Designed for easy on-site mixing and fast track application, the screed levels worn or uneven surfaces while providing a high performance barrier against moisture ingress. Its fast curing profile supports reduced downtime, and it integrates seamlessly with Resimac primers and top coats for multi-layer waterproofing systems.
