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.
