Concrete Surface Treatment — Process Challenge

Concrete Densifiers & Silicate Hardeners

Polished-concrete contractors and floor-treatment formulators buy lithium/sodium/potassium silicate densifiers in drums and totes to harden and dust-proof slabs, across sodium, potassium and premium lithium-silicate grades.
Why It Matters
Polished-concrete contractors and floor-treatment formulators buy lithium/sodium/potassium silicate densifiers in drums and totes to harden and dust-proof slabs, across sodium, potassium and premium lithium-silicate grades.
Solution Approach

Polished-concrete contractors and floor-treatment formulators buy lithium/sodium/potassium silicate densifiers in drums and totes to harden and dust-proof slabs, across sodium, potassium and premium lithium-silicate grades. RawSource supplies the base chemicals that go into these programs. We can help with product selection, grade matching, and sourcing from multiple origins for supply security.

Typical Formulation Workflow
1
System & Substrate Assessment
Define the binder system (waterborne, solventborne, UV, powder), substrate, cure, and the VOC, durability, and appearance targets.
2
Additive & Resin Selection
Match resins, pigments and fillers, dispersants, rheology modifiers, defoamers, or biocides to the formulation and compatibility window.
3
Lab Let-Down & Optimization
Dial in loading and addition order through lab let-downs, checking dispersion, rheology, film properties, and storage stability.
4
Application & Performance Testing
Validate on the real application method and substrate, tracking gloss, adhesion, sag, cure, and weathering before scale-up.
