Select a densifier chemistry (lithium, sodium, or potassium silicate) for a polished concrete project

Steps

1. Identify project constraints first: schedule, slab age/moisture condition, and whether a dye or stain will be applied before or after densification, since these drive which chemistry and application approach fit best.
2. Confirm compatibility between the chosen densifier and any planned dye, stain, or guard/sealer product from the same or an explicitly compatible manufacturer system -- mixing chemistries across manufacturers can cause haze or blotching.
3. Follow the manufacturer's application rate, dilution, and dwell/squeegee timing rather than a generic rule of thumb, since silicate concentrations and reaction behavior vary by product.
4. Verify the slab has cured sufficiently and surface laitance or curing compound has been removed during the grinding sequence before densifier application, since residual curing compound blocks penetration.
5. Document the specific product and lot used for warranty and future maintenance/recoat reference.
