Wood Stain
Characteristics of Wood Stain
When a piece of wooden furniture is finished, the wood grain and surface makes it look natural
and pretty. However, the furniture would even look better if the grain is emphasized. Or, it may look more
beautiful if the wood is of a different shade or tint that can only come from aged wood or a kind of wood not
present in your area.
There is a way to achieve this effect. This method involves the use of wood stains.
A wood stain is made up of pigments, solvent and binder. These components are
also present in paint. But unlike paint which is made up of equal parts of the three substances, wood stain is made
up of mostly pigments with solvent. Only a little amount of binder is present.
This composition allows the pigments of wood stain to be absorbed into the
pores of wood, unlike paint which creates a film of color over the wood. The wood surface takes the color of the
pigment but leaves the substrate, or the natural texture and color of the wood, mostly visible. When the wood stain
is dry, varnishes and surface film is applied to protect the color or to make the wood shiny.
Some people think that wood stains and varnishes are the same. Varnishes do not have pigments
and colors, and are therefore transparent. However, there are some companies that produce a product lines that are
marketed as a combination of wood stain and varnish.
Wood stains viscosity can range from very thin to extremely thick, such as siding stains. Siding
stains penetrate the wood better than paint. They also protect wood from sunlight, ultraviolet rays, water, mildew
and fungal decay. Siding stains also have binders that are softer and more flexible than those used by paints. This
makes siding stains more flexible than paint.
Certain solvent based or oil based stains have bits of paraffin wax in it. Furniture treated in
these kinds of stains cannot be painted over. They can be re-stained, however.
Applying wood stains on wood is either easy or difficult, depending on the type and
characteristics of the wood substrate. For example, freshly cut wood does not absorb the stain well. Aged wood,
however, accepts stains well. End grain and bias-cut grain woods also absorb stains so well that the darkening will
be quite considerable. Wood that has been stripped of paint or washed down with solvents can absorb wood stains
better than those that are not yet painted or stripped.
So, if you need to alter the shade of wooden furniture, just apply wood stain. It is easier and
cheaper than having to look for a certain kind of wood that has exactly the shade that you want.
