Polyurethane varnishes are typically hard, abrasion-resistant, and durable coatings. They are popular for hardwood floors but are considered to be difficult or unsuitable for finishing furniture or other detailed pieces. Compared to simple oil or shellac varnishes, polyurethane varnish forms a harder, decidedly tougher and more waterproof film. However, a thick film of ordinary polyurethane may de-laminate if subjected to heat or shock, fracturing the film and leaving white patches. This tendency increases with long exposure to sunlight or when it is applied over soft woods like pine. This is also in part due to polyurethane's lesser penetration into the wood.

Unlike drying oils and alkyds which cure, after evaporation of the solvent, upon reaction with oxygen from the air, true polyurethane coatings cure after evaporation of the solvent by a variety of reactions of chemicals within the original mix, or by reaction with moisture from the air.

Water exposure, humidity, temperature extremes, and other environmental factors affect all finishes. In other words, the only coat of varnish with near perfect durability is the one stored in a vacuum, in darkness, at a low and unvarying temperature. Otherwise, care and upkeep are required.

VARNISHES

Varnish is resin dissolved in turpentine or in a mixture of turpentine and a drying oil such as linseed oil. There is several resins available with which to make a varnish, and the selection of a resin is guided by use.

Picture Vanish is used as a final coating for a painting to protect the picture and unify the appearance of the surface. It can, for example, make the surface appear either matte or shine, or protect the paint film from chemical reactions with the atmosphere and from mechanical abrasion. Retouch Varnish is using to give a full and wet look to the surface of the unfinished painting before work is resumed. This prevent the eye from been fooled by the unevenness of the light reflected from parts of the painting's surface.

Mixing Varnish is use as an additive to the painting medium to accelerate the drying time, to add gloss, and to given body to a glaze.

Isolating Varnish is a resin that is soluble in turpentine or mineral spirits. When this varnish is applied to a paint film, it will protects it from being affected by the turpentine or mineral spirits in the next layer of paint to be applied.
