Preparation is the key to
a good paint job. Taking the time to repair, clean, and prime your
walls will guarantee a longer- lasting paint finish. Because dirt
and grease will interfere with a good, smooth paint finish, every
surface should be thoroughly cleaned before painting.
Donít rush the preparation process and youíll be rewarded with a
beautiful, durable finish once the project is completed.

Clean the Surface First
To avoid messy streaking, begin washing your walls from the bottom
up. While you can use common household cleansers for the job, many
professional painters use a TSP (trisodium phosphate) solution.
Wearing rubber gloves,
wash with a damp, not dripping, sponge. Rinse thoroughly with clean
water. After the surface is dry, sand lightly where need; then wipe
the surface with a clean cloth.
As you clean, you will
discover any small problems, like cracks or stains, on the surface.
Make those repairs before beginning to paint.
Fixing Common Problems
Problem: Unsightly water or rust
stains require immediate attention because they may indicate a leak
Solution: Check for leaking pipes or dam aged Hashing on
the roof. Before you paint, repair the leak. If the wall surface is
soft or crumbling, repair the area. To seal and cover a
water-stained area that is not otherwise damaged, use a
stain-sealing primer that contains shellac. If left unsealed, the
stain will eventually show through your new paint job.
Problem: Black marks and other
wall stains like crayon or marker are not always easily removed.
Solution: Apply a stain remover
to a clean, dry cloth and rub lightly on the stain. Cover any stain
that is not completely removed with a stain-sealing primer that
MILDEW AND MOLD
Problem: Because mold and mildew
grow in damp areas, check kitchen and bathroom surfaces carefully.
Solution: Test the stain by
washing it with water and detergent. If it is mildew, it will not
wash away. Wash the area with a solution of one part chlorine bleach
to four parts water, which will kill the mildew spores. Scrub with a
soft-bristle brush. Then wash the mildew away with a TSP solution,
rinse with clear water, and allow the area to dry thoroughly before
Problem: Peeling paint occurs
for a number of reasons, and it must be removed before you repaint.
Solution: Scrape away the loose
paint with a putty knife or paint scraper. Apply a thin coat of
spackle to the edges of the chipped paint, using a putty knife.
Allow it to dry. Sand the area with 150- grit sandpaper, creating a
smooth transition between bare wall and surrounding painted
surfaces. Wipe clean with a damp sponge. Spot-prime the area with
polyvinyl acrylic (PVA) primer.
FILLING SMALL NAIL HOLES
Using a putty knife or
your finger, force a small amount of drywall compound or spackle
into the hole, filling it completely. Scrape the area smooth with
the putty knife and let dry (see photo left).
Sand the area lightly
with 150-grit sandpaper. Wipe clean with a damp sponge, let dry,
and dab on PV A primer.
