What
type of paint should I use?
The type of paint you select is determined by the paint job, including
the surface area to be painted, condition and age of the surface,
and type of paint, if any, previously used on the surface. House
paints fall into two general categories: water-based latex and solvent-based
(referred to as oil-based or "alkyds"). Latex paints are
better for color and gloss retention, exterior blistering, long-term
flexibility, odor level, non-yellowing properties, and ease of application,
as well as cleanup. Alkyd/oil is better for hardness and abrasion
resistance, water resistance, scrubbability, flow and leveling,
and adhesion to poorly prepared surfaces. About 75% of all the paint
sold today is of the latex variety.
Can
I paint latex paint over oil-based paint, or an oil-based paint
over latex paint?
As long as the old surface is in good condition, is thoroughly cleaned
and deglossed, you can put latex over oil and oil over latex. Cleaning
and deglossing are especially important if you are putting a latex
over an oil paint. Consider the nature of a particular job to decide
which type of paint is best for its application.
Is
the quality of paint important?
Yes. One of the most important factors in the success of any paint
job is the quality of paint used. Paints are made of three components:
binder, pigment and liquids. Paint also contains other ingredients
known as additives. These ingredients affect the quality of the
paint. Premium paints typically have higher quality of these ingredients
and rely less on extenders for hiding. As a result, premium paints
provide better color retention and uniformity as well as better
hiding characteristics than main line or economy paints. They are
more fade-resistant and flexible so that, when the weather changes
and temperatures fluctuate, the paint film will freely expand and
contract with the surface. Painting with atop quality paint can
add years to the life of a paint job and save hundreds or even thousands
of dollars in the former of lower home maintenance costs.
How
do I prepare an exterior surface for painting?
Every exterior surface should be thoroughly cleaned before painting.
In most cases, this will require both washing and rinsing, since
even soap residue can contaminate the surface and prevent paint
from adhering properly. The cleaning can be done by hand or using
a power washer. Any mildew can be removed by using a solution of
one part household bleach to three parts water. After scrubbing
the surface with this solution, let it remain there for 15 minutes,
then rinse. It is also important to remove any loose, flaking or
peeling paint before applying any primer or paint.
How
do I prepare an interior surface for painting?
As with exterior projects, good surface preparation requires a thorough
cleaning of those surfaces that will be painted. Remove accumulated
dust and dirt by scrubbing surfaces with a sponge and mild household
detergent solution.
How
do I repair a hole in plaster?
To repair large holes, brush or scrape away any loose plaster present
around the hole or between the lath strips. Undercut
the edges of the hole with a special widening tool or an ordinary
can opener-this will help keep the new plaster in police. If lath
strips are missing, take a wad of paper and pack it into the hole
as tightly as possible. Dampen the area with water. Using a broad
putty knife, press a small amount of replacement plaster firmly
against the edges of the hole and pack it tightly against the lath.
Allow the plaster patch to dry until it becomes slightly tacky,
then score it with the' of the putty knife. Tallow the plaster to
dry
completely. Repeat the process again. However, this time, apply
enough plaster so that the patch is level with the surrounding wall
surface. Wait for it to dry. Sand the patch to the level of the
wall. Dust off the area and apply a latex or oil-based sealer.
Can
I paint over Wallcoverings?
While it is usually best to remove wallcovering prior to painting,
if the wallcovering is in good condition, it is possible to paint
right over it. The first step is to make the the wallcovering is
well adhered to the surface. Always use a primer before painting
over wallcoverings Before applying paint, make sure to dull any
glossy surface with medium-grit sandpaper. This will give the surfaces
"tooth," so the new coating will adhere better. Dust off
all prepared surfaces a final time
Which
type of brush to I need?
For large exterior surfaces, use a 4"-wide flat brush with
a thickness of 3/4" to 1". To cut in at the corners of
exterior and interior walls, use a 2"-wide brush with tapered
edges. For exterior and interior woodwork and moldings, use brushes
between 1" and 2-1/2" wide. For precise painting of exterior
and interior window frames and trim, use angled sash brushes between
1" and 2 I/2" wide. For interior walls and ceilings, use
a 3"-wide brush.
