DuPont™ Stone Care Glossary

Acidic
Being or containing an acid; having a pH of less than 7.

Alkaline
Relating to or containing an alkali; having a pH greater than 7.

Cement-based
This type of grout can either be sanded or non-sanded. Both varieties are absorbent and acid-sensitive. Often cement-based grout is polymer modified to prevent or minimize cracking and add strength.

Efflorescence
Efflorescence is a white crystalline deposit that is composed of salts, lime and/or other minerals. These deposits may become visible on many types of building product surfaces such as concrete, stucco, grout, masonry, brick, natural stone, clay, ceramic, and even wood. These salts and minerals are water-soluble and generally come from the ground or where cementitious or alkali substances exist. These salts and minerals travel to the surface, using moisture as their carrier, where exposure to air evaporates the moisture leaving behind salts and minerals on the surface.

Epoxy grout
Epoxy grout is impervious to liquids and does not need sealing. It will not allow bacteria to grow and it minimizes cracking. It is generally used with ceramic, porcelain and quarry tile and not with natural stone.

Fluorochemical
A chemical compound containing fluorine, especially a fluorocarbon. When used in a protective chemical such as a stone sealer, it provides repellency against both water- and oil-based stains.

Grout haze
A light haze of residue that has dried on the surface of the stone or tile after grouting.

Homogenous
Minerals are evenly distributed to form a visibly random crystalline structure.

Impregnating
As a protective treatment, it is one that penetrates the subsurface. It is not a topical coating. It can have both water- and oil-repelling qualities. They are vapor permeable, breathable & generally natural looking.

Neutral
Having neither acid nor basic properties; it is neither acidic nor alkaline. On the pH scale, it measures 7.

Oil-Based Stains
These types of stains are generally not soluble in water and usually are best removed with an oil stain remover that is solvent based. This solvent can be petroleum or citrus based, for example. Examples of these types of stains include cooking oil, hand cream, shampoo and peanut butter.

Oriented
Minerals are distributed according to a certain orientation or direction.

Patina
A surface appearance of something grown beautiful ,especially with age or use.

Red rosin paper
High-quality, heavyweight building paper protective covering and liner. Is useful in a wide variety of construction applications including roofing, flooring and as a general jobsite protective covering.

Silicone
Silicone is often used as a generic term for nearly all substances that contain a silicon atom. In a sealer, silicone helps create water repellency.

Topical
This type of protective treatment forms a surface film. It can serve to minimize wear of soft surfaces. It generally repels water- and oil-based liquids. It does stop acidic foods from etching acid-sensitive stone.

Veined
Geologically a gneiss, not a true granite. Minerals form veins of a different color to the base color, creating a curved or swirled movement in the rock.

Water-Based Stains
These types of stains are generally soluble in water and can be removed with a water-based cleaning solution. Examples of these are cola, orange juice, tomato sauce and jelly.
