All That You Wanted to Know About Wood Finishing (Part 1)…
Wood finishes furniture,wood stain finishes,wood finishes varnish
Whether antique
or contemporary, furniture requires a perfect finish if it has to retain
all that gloss and glory for years to come! There are many terms associated
with wood finishing. If you familiarize yourself with them assessing good
stuff might prove to be a lot easier.
(1) When materials end up bound to one another, they are indulging in
ADHESION.
(2) This ability of one item to stick to another is referred to as BOND.
(3) If there is adherence, there can be separation too! If layers come
apart because of improper attachment of substrate or inter-coat, then
we call it DE LAMINATE.
(4) Below-normal temperatures have an adverse effect on wood finishes;
they crack. This is called COLD CHECKING.
(5) If cracks or voids have gone unnoticed, they are covered by a layer
of finish—BRIDGE.
(6) Should silicon be present, the polished surface will still reveal
craters or pock marks. Just visualize a FISH EYE!
(7) Polished, but still shows age marks or fly speck spotting—we call
this DISTRESSING.
(8) Careless cleaning will not get rid of surface grime and grease/oil.
Thus, as soon as the first coating is applied, the liquid tends to be
wayward in movement—CRAWLING. Certain unpolished areas will show up among
the coated bits.
(9) The oil stain has to be awarded enough time to dry completely prior
to coating. Failure to do that will end up in a bluish haze on the film.
We call this BLOOM.
(10) Should moisture get trapped in the film, the result is a white,
milky cast—BLUSHING. The addition of a blush retardant can resolve the
issue.
(11) Is there a common solvency of the dye and the top coat? Then, expect
the dye or color to be absorbed through this surface. This is called BLEEDING.
(12) Expose well-polished wood to bright sunlight and observe the loss
of color—FADING.
(13) In contrast, if there is no loss of color, then it is FAST TO LIGHT.
(14) Excess heat is not necessary for drying surface coating. This mistake
will result in bubble formation or small holes in the film—PINHOLEING.
And there will be plenty of them!
(15) Conditions for spray painting better be right—no excess heat, no
draft, no excessively viscous material! Or else, a rough texture resembling
an ORANGE PEEL will show up.
(16) Even spraying should result in smooth flow of liquid or perfect
leveling. If these fine particles do not result in a flat and even film,
the orange peel effect is noticeable. This phenomenon is called FLASH
or FLASH-OFF.
(17) To prevent premature “flash” (fast drying) from occurring, a FLASH-OFF
CONTROL SOLVENT (additive) can be added. This extends the “wet” time.
(18) The temperature or flammability is known as FLASH POINT.
(19) BODY refers to the viscosity of the liquid coating.
(20) Whatever solid material is left behind after evaporation is NON-VOLATILE.
