Stain Over Paint

Hello All--

Question--How advisable is it to use a solid body (oil or latex) stain over a previously painted exterior? If preperation and priming is done correctly, does it matter. All thoughts and ideas are solicited. Thanks.

JTP Clarifies Question

I do re-paints. Here, where I work--I must do extensive scraping and prep in order to get ready to re-paint. Many homes I do have at least 1/2 of the total square footage down to bare wood.

I usually scrape, feather sand, spot prime and top coat twice. Was just wondering, giving this situation if the staining idea as opposed to painting ideas was better or worse.

I generally re-paint over paint and re-stain-over stain as most of you suggested is the usual method. I did not realize that stain was just watered down paint. Not being a chemist or up on paint/stain technology, I thought stain and paint (latex and oil base) were significantly different in formulation.

Thanks for all the input so far.

Given the situation I describe in post #11 in this thread, would you stain over the paint or paint over the paint? Thanks.

ive found that all that prep work was a lot of work, so now i just show up and start painting or staining

the jobs seem to go a lot quicker, and im raking in tons of cash.

who cares what type of material you put on,,,just put it on a get on down the road.
Great suggestion John. Think I'll try your system out.

The prevailing opinion here seems to be: Paint over paint, stain over stain. Think I'll stick with that formula. Thanks for the input. It is truly appreciated.

Come to your own conclusions, I guess.

Cabot PRO.V.T. covers previously painted or
stained surfaces in just one coat, improving

species such as pine, white cedar or cypress.
This versatile, fade-resistant and water-repellent
exterior stain provides superior results when
applied on new or reconditioned wood siding
and shingles, cement siding, manufactured
hardboards, previously painted surfaces,

Surface Preparation:
Proper surface preparation is the key to
maximum stain performance. The durability
of this product can be impaired by an
unsound or poorly prepared surface. It is
very important that the surface be clean of
all dirt, mildew stains, loose wood fibers and
other foreign matter. Surfaces must be
structurally sound and absolutely dry.
(Moisture content must be below 15%, or
the wood must be exposed to dry weather
for a minimum of 3 to 5 days.) Previously
painted, stained or weathered wood
surfaces must be either sanded, scrubbed
with a detergent solution or Cabot
Problem-Solver® Wood Cleaner and a stiff
bristle brush, or power washed to remove
the surface layer of all loose wood fibers,
dirt, mildew stains, chalky residues and
other foreign matter. Use Cabot Problem-
Solver Wood Brightener to easily remove
tannin bleed, nail and metal rust stains, and
renew the wood’s appearance. New smooth
wood that is unseasoned or appears shiny
should be allowed to weather sufficiently
before staining, but generally no longer than
4 weeks. The use of Cabot’s Problem-Solver
Primer and Cabot’s Problem-Solver Primer
eliminates the need to weather new wood
and retards extractive bleeding in wood
species such as red cedar, fir and redwood.
Application of Coating:
Finishing: Stir thoroughly before and
occasionally during use. Intermix containers
of the same color. Apply two coats to
new wood for maximum protection.
Apply with a high-quality polyester brush,
roller or spray. When spraying, always
backbrush for optimal results. Maintain a
wet edge to avoid lap marks. Restain every
6-8 years for best appearance.
Spray Application: Recommended tip sizes
and adjustments for airless spray application
are 0.017”- 0.021” at 1800-2000 PSI with
a fan width of 5-8 inches. When using HVLP
spray equipment, see manual for proper
set-up instructions. If you must spray,
always backbrush immediately after each
section is coated to ensure proper coverage.
Number of Coats: Apply two coats on new
wood for maximum protection. Restain
depending on exposure or wear every
6-8 years for best appearance.
Precautions:
Do not apply in direct sunlight, to hot
surfaces, or when air or surface temperature
is below 35°F (1.7°C) or may fall below
35°F (1.7°C) for 24 hours after application.
Do not apply over wet or damp surfaces or
when rain is imminent. Do not thin.
Protect stored containers from
freezing. Do not use on decks or
other horizontal surfaces.
For exterior use only.
