Brand: ttkbuildingmaterials.com Product Index
Availability: InStock

WHAT IT IS

Concrete floor hardener (chemical densifier) is a reactive liquid silicate — sodium, potassium, or lithium silicate — absorbed into concrete floors to chemically react with free calcium hydroxide, forming additional calcium silicate hydrate that densifies and hardens the surface. Available in 5 L pails, 20 L pails, and 200 L drums, it eliminates concrete dusting, increases abrasion resistance, and improves moisture resistance without creating a film coating that can delaminate. Applied by brush, roller, or sprayer with excess squeegeed off, it extends the service life of factory, warehouse, and car park floors without an overlay. Classified under HS 3824999900 · import duty 0% · SST 10%. Also known as pengeras lantai konkrit and 混凝土硬化剂.
