When you apply a liquid densifier to concrete during coloring or polishing, the solution reacts with the free lime or calcium hydroxide present in the concrete to solidify it, making the concrete surface much less permeable and more resistant to stains. Concrete Densifiers Explained. Increase surface density. Improve the wear resistance. The densifier causes additional cementitious materials to form (in combination with the lime in the cement) and tighten the pores.
Can a densifier really waterproof concrete? What is aliphatic urethane? While these products are superior for that application, they are also outstanding for the DIY consumer who just wants to mop a product to harden and densify their floor.
The chemistry of how densifiers work is complex, but in general terms, silicates react with the leftover calcium hydroxide in the concrete , which is a byproduct of the hydration process. Most commonly used on warehouse floors in conjunction with a floor machine to polish and add a shine. LIQUI-HARD concrete densifier and chemical hardener compound is a proprietary, water-base ready-to-use, clear silicate liqui formulated with chemically reactive raw materials to harden and dustproof concrete.
This waterborne solution, when properly applie offers substantial improvement in abrasion and chemical resistance and will significantly improve the durability of the concrete surface when compared to untreated concrete.
