Concrete densifier vs penetrating sealer — silicate, silane, and acrylic chemistries compared, with the densification, waterproofing, and service-life numbers that matter to specifiers.
Why organic sealers fail at high temperature and why silicate-based densifiers survive — documented envelope, specified applications, and honest limits for high-temperature concrete protection.
Lithium, sodium, and potassium silicate concrete densifiers compared — chemistry, reactivity, residue behaviour, and how to match the tier to the application.
