Does Lithium React Faster?
Reaction speed cannot be determined from the alkali type alone. Lithium-containing products are often promoted as faster or more complete reacting, while some formulated potassium products react quickly on porous concrete. Silicate concentration, particle size, pH, viscosity, penetration additives, temperature and concrete porosity all influence performance.
Comparing Fortis Densifiers
| Consideration | Potassium/Lithium | Premium Lithium |
|---|---|---|
| Formulation | Potassium and lithium silicate blend | Lithium silicate with penetration additives |
| Positioning | Economical general-purpose densifier | Premium polishing densifier |
| Typical concrete | Porous, trowelled and general industrial floors | Dense, decorative and refined polished floors |
| Typical projects | Warehouses, factories, workshops and large areas | Homes, retail floors and showrooms |
| Choose when | Cost-effective hardening and dust reduction are priorities | Penetration and a premium polished finish are priorities |
Choosing the Product
Select Potassium/Lithium Densifier for economical concrete hardening, dust reduction and general polishing. Use Premium Lithium Densifier for premium polished concrete systems and floors requiring a more refined finish.
What Controls Performance?
The concrete must be clean, sound and able to absorb the treatment. Sealers, curing compounds, oil and contamination prevent penetration. Apply between grinding stages and keep the surface evenly wet for the period stated in the data sheet. Remove excess before it dries because pooled silicate can leave white residue.
Is Densifier a Sealer?
No. Densification can reduce absorption and provide limited resistance to contamination, but it does not replace a dedicated stain-resistant sealer or enhancer. Always test the selected system on the actual concrete.
