Concrete Densification Explained Simply

A chemical solution called a concrete densifier is applied to concrete surfaces in the construction industry to enhance their resilience, strength, and general functionality. It makes them harder, more durable, and more resistant to surface damage and moisture penetration.

Adding this to your concrete polishing services floors can increase their lifespan by decades or more, and also make them easier to clean, which helps cut down on maintenance costs. The real trick is knowing when to apply a concrete densifier, and that can be the source of some confusion among contractors.

The answer is 14-28 days after the concrete has cured, but there are some caveats. The densifier needs to seep into the concrete and react with the free lime, or calcium hydroxide, found in the matrix of the cement. This reaction produces insoluble calcium silicate hydrate crystals that fill the concrete pores and capillaries.

Polished Concrete Safety Features

A concrete densifier can be applied either before or after you stain the floor, but it is best to do so after a light abrasion such as buffing or grinding. This will remove any residual stains, oil spots or dirt and prepare the slab for the chemical treatment.

There are several different types of concrete densifiers, and each has its own unique chemical makeup. Stepheson notes that lithium densifiers are popular for polishing concrete because they work quickly and efficiently to achieve the desired outcome. He also recommends that you consider the type of stain you will use — film-forming stains or acid stains – before you decide whether to apply the densifier before or after staining.
