VINYL
SIDING
Question
We recently purchased a 22 year old ranch house with light green
(minty fresh!) vinyl siding. The siding is original to the house
and is somewhat faded, although not much (we have a piece of the
siding in the garage to compare it to). Can we paint this? We'd
like to paint it a medium gray. What do we need to do to prepare
the siding for painting? Is it ok to go somewhat darker than the
original siding? How long will the paint job last (before needing
repainted)? What is the best outside temperature to do this type
of painting?
Answer
Here are some points and suggestions:
1.
With vinyl siding, DO NOT paint any darker than the original color,
or the siding can get too hot from sunshine, and warp permanently.
You should probably choose a light gray.
2.
Kill any mildew that is on the siding now. There are a number of
factors that affect tendency to grow mildew on a paint job. Included
is the removal of any mildew on the surface prior to priming/painting.
3.
Then clean the surface by scrubbing with detergent, then rinse thoroughly;
or use power washing with plain water, as mentioned above. Be sure
to aim the spray level or slightly downward, and keep the tip 6"
- 8" from the surface.
4.
Apply one or two coats of a top quality 100% acrylic exterior house
paint, in a flat, satin or semi gloss finish, depending on appearance
wanted.
Normally,
a primer is not necessary with cleaned vinyl siding. Use a quality
3" polyester-Nylon brush, or spray the paint. The light gray should
last very well. If the surface is sound, clean and free of chalk
when painted, and you apply two coats, you should be able to get
at least 10 years, possibly longer.
