Abrasion Resistance

The ability of a material (such as a floor surface) to resist damage from scratching, rubbing or scraping.

Abrasive Blasting

The act of using an abrasive material propelled at a high speed onto a flooring surface to clean or roughen it. It is commonly referred to as sandblasting, shot blasting, or bead blasting.

Accelerator

A mixture, that when added to concrete, increases the rate at which it hardens or strengthens.

Acetone

One of the most common solvents often used to clean residue off a surface or to thin other products. It is a flammable substance.

Acid Etching

A process of applying phosphoric or muriatic acid to a concrete floor which cleans and 'etches' the surface.

Acid Stains

An advanced method of colorizing concrete that involves applying an acidic, water-based solution mixed with inorganic salts to the floor's surface for 1-6 hours. The solution is then neutralized with ammonia and water and cleaned up with a wet/dry vacuum. The appearance is generally earth toned and may appear marbleized.

Adhesive Stencils

Stencils with adhesive backing that are often applied to concrete or another surface and then used to create a pattern or picture by using a stain, dye, gel, or other method to apply color.

Admixture

An ingredient other than water, cement, and aggregate that can be added to concrete at the site of installation or at the factory to modify its properties in a number of ways. For example, it can lengthen or shorten hardening time.

Aggregate

A material that is added to wet concrete to improve its structural durability. Common aggregate materials include gravel, sand, rock, and stone.

Air Content

A measurement of the amount of air trapped inside concrete expressed as a percent of the entire volume.

Air Entrainment

The process of adding microscopic air bubbles into the concrete. This helps improve floor's durability as well as increases floor's resistance to damage due to freezing.

Alligatoring

When a finish cracks into large segments that appear to resemble alligator hide. This is usually caused by applying coating too heavily or over other coatings that have not cured. It can also be caused by using thinners meant to speed drying time or by applying a layer of finish over another layer with less elasticity.

Antiquing

A method of giving a surface an aged, slightly worn appearance.
