Lithium Silicate Concrete Sealer

These are excellent choices but a newcomer to the field is the lithium silicate sealer.

Lithium silicate concrete sealer. It chemically reacts below the surface to form a permanent calcium silicate hydrate csh structure within the pores that can only be removed when the concrete itself is removed. Normally when calcium hydroxide comes to the surface of fresh concrete it reacts with atmospheric carbon dioxide producing carbonation calcium carbonate. A silicate is a penetrating sealer made up of small particles of sealant. The difference is that the carrier which only functions to transport the silicate into the concrete is lithium instead of sodium.

Lithium silicates are the most prevalent of all the silicate technologies and possess a much smaller molecular structure than sodium and potassium silicates. This reaction produces a calcium silicate hydrate within the concrete pores. Lithseal sc deeply penetrates and reacts with cured concrete. These small silicate particles are suspended in a sodium or lithium carrier that helps transport the particles past the surface pores of the concrete.

Lithium silicate concrete densifiers are fast acting silicate sealers used to increase the strength and density of the concrete. The reaction is greater when the concrete humidity is high and when bleeding is prolonged. They chemically react with the free lime and calcium below the concrete surface to create a permanent calcium silicate hydrate barrier within the pores. The introduction of the lithium silicate technology has been one of the biggest breakthroughs in concrete sealer technology for densifiers and hardeners within the last 50 years.

In theory impregnates containing lithium sodium or potassium silicate compounds are designed to penetrate deeply into the structure of concrete and fill its pores creating additional bonds in floor concrete. Usually these products are applied with a roller or brush and then polished. Lithium silicate concrete sealer densifier lithseal sc is a premium lithium silicate sealer densifier for concrete surfaces. Keep in mind that silicates both sodium and lithium do not offer any type of waterproofing protection.

It is an ideal treatment for machine troweled burnished or polished concrete surfaces. L3000 the armor l3000 is a concentrated fast acting lithium silicate densifier and surface hardener.
