| Q |
How often do I need to paint my house? |
| A |
In my professional opinion. I believe a new house should be
repainted with in 3 years after being built for the simple reason 95% of new construction
painting is sprayed on very quickly over construction dust and dirt often over unprimed
wood. As a result of this you may notice rapid deteration of surfaces and mold and mildew
appearing. Left untreated will lead to costly repaires. A properly power washed, prepared,
primed, and finish painted house should last 6to8 years.

| Q |
What about my older house? |
| A |
Most homes 50 to 100+ old have heavy coats of oil and most
cases lead base paint often cracked or flaking off This is due to heavy paint build up to
as many as 40 coats. If you are renovating the best bet of course would be to remove all
old paint by striping or burning off power wash surfaces to clean, prime with a oil
primer, re-caulk and putty and finish coat with 2 coats acrylic latex paint. This should
last a good 10 years.
If paint is tight however power wash to remove dirt, sand surface smooth as
possable, full prime with a latex bonding primer, and finish coat with a acrylic latex
paint. I have had great results with older houses and can say 7 years or more are expected
for the described paint job.

| Q |
I was told oil paints are still the best is that true. |
A
|
Yes and No for Interior wood work I feel that oil base
paint are superior, they give much richer look, are very scrubable and easily cleaned,
less likely to chip and is not effected by the oils on your hands that can raise a latex
paint over time. But on Exterior wood surfaces a acrylic latex is the only way to go the
acrylic latex acts like a rubber type coating that will expand and contract with your
house during the changing temperatures and won’t crack like a hard oil will, acrylics
are fade resistant, chalk resistane, and mold and mildew resistant, and if applied right
will last for many years.

| Q |
I had my deck restrained about a 1 year ago and it’s already
fading why? |
| A |
There is a couple reasons, first depending on the stain
used and condition of deck. Most stain manufactures will tell you that a deck should be
restained every 12 to16 months due to the harsh conditions a deck indures sun, rain, snow,
foot traffic. It also depends on the type of stain. Transparent stain has no real pigment
and allows the natural color of the wood to show through but are least durable.
Semi-transparent stains have more pigment and put a slight color change on your deck but
still allows the wood grain to show through most have UV protection and considered a
sealer- stain these may last slightly longer. Solid color stains are the closet to paint
like the name implies they have solid pigment color that will cover your wood like paint.
Like paint you have many colors to choose from. Solid color stains will hold up the
longest for aparent reasons but you’ll lose the natural beauty of you deck. All stain
manufactures offer their products in both oil and latex and over the last few years
continue to improve there product to last longer. One thing to note most cases your deck
should be striped and powerwashed before re-staining. Striping products can be bought at
all paint stores and many have powerwasher to rent.
