LD 1800

SureCrete’s LD1800 is a liquid, lithium-based, densifier hardener for concrete and cement-based surfaces. When applied it provides a clean, safe, economical “stand-alone” finished concrete floor. To harden concrete, this penetrating treatment reacts chemically with the free lime in concrete to produce calcium silicate hydrate within the concrete pores, making the concrete stronger and more durable.


LD1800 is a concrete lithium densifier that is an alternative to conventional sodium or potassium sodium hardeners. As these traditional densifiers leave a high concentration of salts on the surface of the cement. Our lithium densifier will not contribute to alkali-silicate reaction (ASR). LD1800 is non-flammable, VOC compliant, environmentally safe, and non-staining concrete hardener.

As a surface preparation product, LD1800™ can help to strengthen your overly-porous or weak concrete surface. This product can contribute to extending the lifespan of your slab by contributing to solidify the “cream” or top layer of your concrete. It does this by filling in many of the small voids in the concrete with liquid silicate that hardens slowly over time. Whether you are looking to repair an old slab that is losing its strength or only trying to prepare a freshly poured concrete substrate that you want to last longer than the competition, LD1800 can make your jobs stand the test of time with a nearly negligible cost pre square foot.


How Should I Apply LD 1800?

You can pour it onto the concrete surface directly or spray it out of a pump-up sprayer. Which ever you choose, you must put enough densifier down to keep it wet for 10-15 minutes.


Does Lithium Densifiers Come With A Sealer Built-in?

Although some make come with a fluoropolymer sealer combination. SureCrete’s LD 1800 does not carry a sealer in it. This gives it the advantage to be used in concrete surface preparation. As it will not contribute to delamination issues.


LD1800 Coverage Rates

Coverage varies based on the surfaces porosity. Typically hard-troweled concrete is applied at 300-400  ft² per gallon  (27.9 m² – 37.2 m²). On porous surfaces you will be more like 100-200  ft² per gallon (9.3 m² – 18.6 m²).

VOC Rating   0 g/L
Shelf Life   1 year in original unopened container
