Concrete Densifier

Concrete densifiers are concrete hardeners that once applied penetrate into the concrete and cause a chemical reaction. During this chemical reaction a concrete densifier reacts with free lime and calcium found naturally occurring in concrete. Calcium silicate hydrate (CSH) is formed by this reaction and fills in the small pores and capillaries of the concrete. This process increases the strength of the concrete making it up to 50% stronger and more durable.

Lithi-Tek 4500

Water-Based
Concentrated

Best used as a primer before using a concrete sealer or during the concrete floor polishing process if a polished concrete floor finish is desired.

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.

Sila-Tek 3500

Water-Based
Concentrated

Best used during the concrete floor polishing process if a polished concrete floor finish is desired.

The Sila-Tek 3500 is a cost effective, penetrating, sodium silicate based concrete densifier that increases the strength of concrete.

By using the 3500 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.

Sila-Tek 3500 is concentrated and needs to be mixed with distilled water prior to application. One Sila-Tek 3500 is mixed with 4 parts water. Two coats are applied with either a sprayer or roller roughly 5 minutes apart.
