WOOD STAIN AND/OR VARNISH
Staining is the process of dissolving solvents with colors onto material surfaces that would subsequently be absorbed by substrates materials such as timber. Staining can be difficult or easy to perform, it involves using properly aged timber boards and using dye or pigment finish depending on the finish. The differences between the both are the particle sizes.
Pigments have larger particles substances that would present a final finish color that is consistent with the deep pores of the wood. And since, it has larger particles that are unable to fit within detailed timber pores, it dry’s within the pores to create a smoother surface.
Dye stains work similarly to pigment substances, however dye stains have smaller particles which have greater detail that would give a lighter color between the timber pores. Because it is more detailed, it transmits the colors differences between pores more evenly that would mean lighter and better flowing consistency in color.
Varnishing is a transparent or colored finish that provides a protective film and gloss finish to the substrate which enhances the natural appearance of the timber. The type of varnish used is determines by the type of timber and finish, it could be matt, satin, semi-gloss or gloss.
Once, the timber type, finish and purpose is investigated then one or more types of Varnish can be used. These include oils, polyurethanes and epoxy, each with a specific advantages and disadvantages that would interest the user. Oil varnish normally tends to soak within the timber making it very durable in wet conditions, acts like water proofer. Polyurethane is synthetic compounds that do not go as deep, however still provide a clear finish of the natural appearance of wood. Lastly, epoxy are chemical based substances that similar do the same as polyurethanes, however with the difficulty of applying and sanding in the future.
In the industry, polyurethane is vastly used for its flexibility, durability and final finish and is therefore recommended by Shine Painting services.
