Lythic Densifier with reactive colloidal silica is a densifier for concrete, used to improve the performance and appearance of concrete floors. It can reduce dusting, efflorescence, and ASR. It can also increase surface hardness, compressive strength, and abrasion-resistance.
Lythic Densifier is permeable and does not form a film on the surface, allowing the concrete to remain breathable. Therefore, it will not yellow or cause cracking issues.
After application, it will "not change" the color and brightness of the concrete surface (the appearance of the concrete will remain exactly the same as before). If a gloss is desired, please follow the procedure for hardening and polishing concrete.


1. Prevent dusting, efflorescence, and A.S.R.
2. Increase surface hardness, compressive strength, and abrasion-resistance.
3. Reduces capillary size to make the surface less porous
4. Does not yellow or whiten concrete
5. Particles are approximately 5 nanometers (5nm) ensuring superior penetration. Fast reacting – one hour or less.
6. Safe to handle – pH=9. Lower pH than silicates.

Material Packaging

1.  Concentrate 1 Liter (5:1 mix with clean portable water)
     *Note the concentrated product will yield 6 times the volume when mixed 5:1 with clean potable water.
2.  Ready-to-use 1 Liter 

Coverage Rates

Lythic Densifiers will yield different coverage rates depending on the porosity of the surfaces. Test on a small sample area to determine appropriate application rate and technique before applying to entire project area.
Use these coverage rates as a starting point to determine necessary application rate. Coverage rates are based on a mixed ready-to-use (RTU) liter of Lythic Densifier.

  • High Porosity Concrete: 6~10m2 
  • Medium Density Concrete: 7~12m2 
  • Hard Concrete: 9~15 m2

How to use

1. Concrete should be cured for 28 days before application.
3. Agitate Lythic Densifiers RTU mixture before pouring into sprayer. When it comes to Concentrate, 5:1 mix with portable water before use.
4. Pour Lythic Densifiers RTU mixture into sprayer. Keep sprayer pressure at optimized level, allowing even distribution when applying to concrete surface.
5. Spray apply Lythic Densifiers, holding spray tip 12-24 inches above surface and moving in a circular motion to achieve even distribution. Spray enough to form an even sheen and ensure complete saturation of surface. Avoid puddling. 
6. Keep the surface wet for 10 to 15 minutes, applying additional Lythic Densifiers only as needed. Areas of higher porosity will require more Lythic Densifier. 
7. Allow surface to dry completely before further operations commence.
2. Surface must be clean and structurally sound, and clear of membrane-forming curing compounds, oils, dust and other surface contaminants that will prevent Lythic Products from having full contact with the concrete.


1.   After completion of the application, please clean all equipment immediately with water.
2.   Any adjacent areas, surfaces, or objects not intended to be treated with Lythic Densifiers should be protected from overspray or drift with plastic sheeting or other proven protective material.
