Wood conditioner for wood finishing.
The
best way to get the maximum advantage of the staining result is by applying the stain
directly to the raw wood. We
can apply stain by spray, dip, brushed or wipe, but the stain must wet and penetrate
into the wood surface. By this application we can get the maximum
beauty of wood. This method will let the stain to color the wood and enhance the natural grain and pores of the wood. But this
finishing system is often causing problem in some soft wood. Some
types of woods such as: pine, maple, alder, etc. are soft porous which has
high absorption to the stain. The
application of stain directly to the wood has high risk to get problems cause by
too much absorption of stain such as: color too dark or blotchy color finish. To
overcome this problem, some finishing materials suppliers have created a
special finishing material that is called as “wood conditioner”.
Wood conditioner is special materials to
address the problem of blotchy color in the soft wood. Wood
conditioner is like a base stain, or thin sealer that serves to reduce the
penetration of stain into the wood. Wood
conditioner may have different types from one product to another, but in
principle it is a barrier to avoid too deep penetration of the stain into the
wood. Wood
conditioner is applied to the raw wood before the stain application. The
way the application of this wood conditioner can be by wet spraying, wiping, or
brushing until it soak and wet the wood surface evenly. Wood
conditioner should be applied evenly to completely wet the surface so he could wet
and fill at the wood surface that has a high porosity.
The
wood conditioner is working similarly with the glue sizing or sealer sizing,
but the wood conditioner should be easier to be applied since it is the material that is specially design to handle the
soft wood. Some types of wood conditioner can be followed by stain application
without sanding. Wood
conditioner of this type is more work as stain base which will reduce the
strength of the stain, so it does not too wet and soak into the wood surface. This
wood conditioner is usually an oil base and must be followed by the application
of stain with the same type (oil base stain).
The other wood conditioner requires drying and sanding process to produce smooth wood surface. This material contains some sealer that will stiff the wood fibers. It has to be sanded to produce smooth and even surface. This wood conditioner can be followed by application of different types of stain. The best way to apply the stain is by spray application since we can do better control to the stain thickness. The application of stain by brushing or dipping has bigger risk to get blotchy color problem, since the uncontrolled the stain thickness at the surface.
