Wood Finishing Terms Flashcards
the property causing one material to stick to another
adhesion
a coat applied which separates the substrate from contact w the topcoats
barrier coat
when a dye or color absorbs through the top layer due to a common solvency of the topcoat and the dye
bleeding
a bluish haze of a film ususlly caused by insufficient drying timr of the oil stain before topcoating
bloom
a white milky cast in a film which is caused by trapping moisture into the film
blush
reducer with slower drying properties
blush retarder
thickness of viscosity of the coating while in liquid form
body
adhesion of or ability of two items to stick to one another
bond
when a finish forms a layer over a crack or void
bridge
method of filling a defect in wood using a hot knife and a burn in stick of resin or shellac
burn-in
act of applying voat to a surface
coat
any material applied to a surface leaving a protective layer on that surface
coating
the cracking of a finish due to exposure to cold temperatures
cold checking
when a coating applied tends to flow away from areas leaving them uncoatrf. usually caused by grease or contamination on the surface to be coated
crawling
the separation of layers due to lack of intercoat or substrate adhesion
de laminate
fly speck spotting (and/or other age marks) in the finished surface or on the substrate
distressing
coloring material that dissolves completely in a system very transparent
dye
the elapsed time at which a coating has reached its optimum hardness
dry hard
the loss of color due to exposure to sunlight
fading
color which is not significantly affected by exposure to sunlight
fast to light
pock marks or craters that show up on finished surface when silicone is present
fish eye
the point at which a sprayed coating stops flowing or leveling, premature flash causes orange-peel when atomized droplets do not flow into a completely flat and even film
flash or flash off
an additive that extends the wet time or “flash” of a sprayed or brushed coating
flash off control solvent
temoerature at which a material will ignite when exposed to a source of ignition
flash point (flamability)
act of very heavily applying a coating to the substrate
flood
the fluid sheetung and leveling of a coating
flow
shellac base coating which is applied manually by padding it into the surface
french polish
an oil based pigmented treatment which is applied between lacquer coats to accent or give a grained effect
glaze
shininess or reflectability of a surface
gloss or sheen
an uncoated area of a coated surface usually missed unintentionally
holiday
used in reference to coatings and/or stains which are not capable of being mixed with one another
incompatible
the act of applying a coat which will smooth out a previously rough (orange peeled) coat
leveling
the softening and repenetration of a previous coat resulting in anything from an orange peel to a stripping effect. usually caused by applying strong solvent coating over a curing type coating
lifting
the solid material which is left after a total solvent evaporation
non-volatile
the primary resin material used in making lacquer
nitrocellulose
degree of hiding a pigmented coating. opposite of transparent
opaque/opacity
a rough surface of film similar to the appesrance of the skin of an orange. usually cuased by spraying in high heat, draft or material that is too thick or heavy in viscosity
orange peel
finely ground insoluble puder which contributes color to a coating. usually very color fast
pigment
appearance of numerous small holes in a film, usually caused by bubbles due to high heat dryinf of the coating
pinholeing
a coating which is first applied to a bare surface
primer
to add sa solvent in order to thin a material to a workable thickness (viscosity)
thinner/reducer
lacwuer or other coating formulated to give better filling and sandability than the topcoat products
sanding sealer
the surface or material to be coated
substrate
clear e ough to see through
transparent
allows light to pass through but not clear enough to see through
tanslucent
the thickness of a coating material in its liquid form
viscosity
solvent portion of a coating
volatile
very thin coat of shellac or sanding sealer or coating
washcoat
term used to describe the color of a coating in its liquid form ——meaning as clear and colorless as drinking water
water white
