finishes will protect wood from
direct spills, steam, scatches and damge and chemicials like vinegar, lemon juice, alcohol, oils, household cleaners, solvents
can modify color and enhance grain, patterns in wood.
finishes
surface preparation

proper sanding is also required to remove imperfections like
machine marks from saws, jointers, planers, routers, excess glue, miscc dents and other defects, cross-sanding

basic wood finishing

self seal
two main types of stains
dye stains and pigments stains
pigment
on open grained woods like oat, walut a good contrast is obtained because of the higher concentration of pigments
pigment stain
On close-grained woods like maple and birch, staining will be lighter because the pigments are mainly lodging in the sanding scratches. Too fine a sanding during finish preparation will make for an even lighter appearance.
On close-grained woods like maple and birch,
Dye particles are soluble and penetrate deeper than pigments, adding depth to the appearance. If the word “penetrating” is used on the label,
dye stain
staining will be darker and more even than with a pigmented stain. However, uneven densities in closed-grained woods still give a blotchy appearance.
On close-grained woods like maple and birch

Spray and wipe stains:
Similar to wiping stains, but meant to be applied by spray gun. Blotchiness is reduced, compared to traditional wiping stains. There is less obscuring of the grain than with spray stains
are used to lighten the colour of wood before a stain is applied
