Latex Paint Characteristics & Usage
Thins with water: Spills, spatters, brushes, rollers, etc. cleaned with
warm, soapy water.
Dries faster than oil base paints. Most can be re-coated within four
hours.
Low odor. No solvent smell.
Easy to apply.
Use with nylon or polyester brush (not pure bristle), polyester or synthetic
roller covers (not lambswool) or flat applicators. (The natural bristles
and lambswool absorb water in the paint and become soggy.)
Has flat to high gloss range.
For interior or exterior use, depending upon product.
Latex paint can be applied over oil based paints. When painting over
a semi-gloss or gloss surface, dull the old paint with sandpaper or a dulling
solvent first.
Avoid using latex paints when surface is above ninety degrees or below
forty five degrees. High temperatures may evaporate the paint too quickly
and cause poor flow for an uneven finish. Low temperature may prevent it
from forming a uniform film that will also create an uneven finish.
Check weather forecast to be sure that rain isn't expected before the
latex paint has had a chance to set-about two to four hours.
Most latex paints can be stored for at least two years without the risk
of deterioration. However, exposure to extremes of heat or cold may shorten
the paint's storage life. Severe, prolonged or repeated exposure to freezing
temperatures could cause separation in the can. Stir to bring back the
correct consistency.
Oil Paint Characteristics
Thins with solvents such as mineral spirits or turpentine. Brushes,
roller covers, and other tools to be cleaned with solvent, not water.
Dries slower than latex paint. Waiting overnight to re-coat is necessary.
Higher odor level than latex during application and drying.
Use pure bristle or polyester brush or lambswool or polyester roller.
Has flat to high gloss range.
For interior and exterior use, depending upon product.
Varnish Characteristics
Solutions of resins in a drying oil. Contains little or no pigment.
Dries and hardens by evaporation of the volatile solvents, oxidation
of the oil, or both.
Recommended for both outdoor and indoor applications where a hard, glossy
finish is needed for weather protection.
Enamel Characteristics
Basically a varnish with pigments added. Same basic durability and toughness
of a good varnish.
Produces easy-to-clean surface.
In proper formulation, can be used for interior and exterior. For the
highest quality interior work, an undercoat is required.
Shellac Characteristics
Long-standing favorite for finishing wood floors, trim, and furniture.
Apply in dry, warm air to avoid clouding.
Dries dust free in fifteen to twenty minutes.
Can be used as a pre-staining wash coat to obtain even stain tone on
porous or soft wood such as pine.
Can change tone of an already shellacked surface by tinting with alcohol-soluble
aniline dye.
Instead of re-staining, pigmented shellac (also called shellac enamel)
can be used as a sealant over stained finishes for a uniform, freshly-painted
surface.
Sheen Characteristics
FLAT. Lusterless, non-shiny appearance. Most often used on interior
walls, exterior body or walls of homes and commercial buildings, and associated
with interior and exterior stains.
EGGSHELL. Slightly higher than "dead" flat. Is usually an enamel
paint. Most often used on interior and exterior walls and on doors and
trim.
LO-LUSTRE. Low sheen or "satin." Slightly higher than eggshell,
but lower than full semi-gloss. Popular interior enamel sheen. Most often
used in kitchens, baths, and on interior doors and trim as it's resistant
to marking, easy to clean, and more washable than most flat latex.
SEMI-GLOSS. Midway between flat and high gloss. Associated with
enamel paint and most often used in kitchens, interior doors and trim and
exterior siding and trim. Very resistant to marking and easy to clean.
GLOSS/HIGH GLOSS. Very shiny appearance. Enamel paints. Used
on interior and exterior surfaces. Popular for furniture, toys, floors,
exterior doors and trim. Resists marking and easy to clean.
