Construction Method
Base Surface Treatment: Clean concrete thoroughly, remove all dust, oil, coating and sealant; wet surface and remove standing water.
Application: Apply generously with low-pressure sprayer or roller, keep surface wet for 20–30 minutes; reapply to areas that absorb quickly; do not allow pooling.
Second Coat:For severely weak or dusty surface, apply second coat after first is absorbed (30–60 minutes); scrub surface with stiff brush during application.
Curing & Cleaning: After 1–2 hours, rinse off excess residue with water and squeegee; full hardening in 7 days; can polish for glossy finish.
