Wood varnish is a clear varnish that is applied to wood. Wood varnish has been used for centuries to protect the surface of wooden items such as furniture, cabinets, and bookshelves. Wood varnish usually comes in two different types. The first type of wood varnish is an acid-based sealant. The second type of wood varnish is a wax-based sealer. Wood varnishes are made from three basic ingredients: solvent, resin or oil, and pigment or dye. Wood veneers are also sometimes given an unfinished coat of clear paint to protect them against stains and UV radiation. Wood stain can be applied over the paint to provide more color variation that matches with the rest of the room. Wood varnish protects wood surfaces from moisture, water vapor, and acidic or alkaline substances. Wood varnish also provides a smoother surface that is easier to clean than bare wood. Wood varnish adds shine to the appearance of the object it coats and enables easier cleaning of spills on wooden furniture. Wood varnish is sometimes called a wood sealant or a wood coating. Wood varnish gives the object it coats a clear, protective exterior coating.
Wood varnishes are applied to wooden surfaces before they become dry and when the humidity in the air is low. Wood must be clean and free from dust particles when applying varnish. Wood varnishes are also applied to surfaces before they become dirty. Wood varnish is sometimes applied multiple times or it can be reapplied after the original coat becomes dry and chips due to usage. Wood varnish should always be tested on a small, inconspicuous area of wood before applying it to the rest of the object that is to be varnished. Wood varnish can also damage some types of wood such as lacquered or lacquered plywood and some types of particleboard. Wood varnishes should not be applied when the temperature in the air is below 7 degrees Celsius. Wood must also dry out completely before varnish is applied. Wood that has not dried out will cause the varnish to dry slowly and will lead to deformation of the object. Wood varnishes should be brushed on wood surfaces instead of sprayed onto them because applying the varnish with a brush prevents bubbles from forming in the coating. Wood varnish cuts down on reflection of light off the surface it coats by 95%. Wood varnish should not be used on surfaces that need to have a high gloss or a clear reflection. Wood varnishes with higher concentrations of pigment will dry darker than those with little pigment. Wood varnish should also never be applied over paint.
Acid-based clear finishes are pigmented to show a clear, protective coating on the surface of the wood. Acid-based clear coatings can be left clear or tinted with colour dyes or pigments. These types of wood varnishes have low viscosity's and dry quickly. The clear coatings penetrate the wood for a durable finish that protects against moisture and ultraviolet light damage.
These clear coatings are good for people who want to change the colour of the floor or leave it clear with no treatment at all.
Oil-based clear finishes work as a high quality, clear top coat for surfaces of wood, metal and masonry. They have a clear appearance on the surface of the substrate they are applied to. Different from water-based clear finishes, oil-based clear varnishes dry more slowly but provide a higher degree of protection against moisture and abrasion damage. The clear coats do not penetrate into the substrate and the clear coatings dry to a hard film that is extremely durable and scratch-resistant.
Oil-based clear finishes are good for furniture, wood flooring, exterior decks and fences. Oil-based clear varnishes provide varying degrees of gloss, depending on how many coats of clear finish are applied to the substrate.
Water or solvent clear finishes dry quickly, are low in viscosity and provide an excellent clear coat over many surfaces. These clear coats are durable, well-bonding to wood substrates and are ideal for water-based stains. They can also be used as a clear topcoat on oil-based stains.
Water or solvent clear finishes are good for wood flooring, doors and window sashes. They can be used as clear coats on acid-based clear finishes to prevent yellowing of the clear finish.
Floor varnishing is a clear coat that provides an abrasion-resistant surface that can be used to protect and enhance the appearance of a floor. Wood floor varnish is a clear coat that protects floors from damage due to moisture, scratches or scuffs. The clear coatings are applied over unfinished wood floors, leaving the surface clear and durable.
Floor varnish clear coats are available in oil-based clear finishes and water clear finishes. The clear coats leave a clear, glossy finish on the floor.
Floor varnish clear coats are available as a single-component coating or two-component coating. Floor varnish clear coatings can also be pigmented with dyes to colour the clear coats over stained wood surfaces.
