The Lithi-Tek 4500 is a penetrating lithium silicate based concrete densifier that can make concrete up to 50% stronger. Lithium based silicates penetrate deeper and work better than traditional sodium silicate based densifiers. The 4500 can also be used as a primer on poured concrete substrates before using a concrete sealer. In addition to making the concrete stronger, the 4500 acts as a bonding agent to increase the adhesion of the subsequent sealer. The 4500 also makes concrete less porous and works great when used in conjunction with a water repellent sealer.
By using the 4500 prior to polishing concrete it will make the concrete harder and will give it more of a shine to resist stains and water damage. If concrete densifier is not used during the polishing process the concrete can wear faster and lose its shine quicker.
Lithi-Tek 4500 is concentrated and needs to be mixed with distilled water prior to application. One part Lithi-Tek 4500 is mixed with 3 parts water. One coat is applied with either a sprayer or roller.
