1st time visitor, so ease up
on me for asking this question
for what I bet is the 3 bazillionth
Subject: a somewhat large, pressure-treated deck (16x32').
I usually pressure wash it annually as it
gets blasted by the sun for the majority
of the day. Mildew & the like doesn't
seem to be an issue, but it gets quite
"gray" by Fall. Over the years I've only
used two products to seal it: Thompsons
& CWF. Neither seem to hinder it from graying
up and from what I've read, the only way to
really retard this is to "stain" it and I don't
want to. Thompson's is apparently not highly
thought of these days but it is the least expensive of these
types of treatments and since I do the drill
every Spring, is it really worth incurring the
additonal expense of another product? I also
do not want to use anything that requires "roll or brush"
applications because I have better things to do with my
time. (I'd rather spray something)
Right now, I am being referred to a couple products that
are new to me: Behr "Weatherproofing Wood Finish"
and Olympic "Clear Wood Preservative/ Water Guard
Wood Clear". I'm not sure of the pricing on the Olympic stuff
yet, but the Behr product is about $ 80-90 for five gallons.
(I will need about 10 gal. for the job) Thompson's is alot less.
Sorry for the darn "book", but I'd
be appreciative of any advice
CWF is much better than Thompson's. But really, anything is better
than Thompsons. Blocking the UV rays is what you need, and neither of
these products will last a long time. However, a good decking stain
will outlast a clear finish by 3 or 4 times. A stain or paint is just
much better at blocking out UV rays. Since you said you did not mind
yearly applications and do not want to stain the deck, go with the
CWF. I use CWF on my redwood deck furniture, but I use Cabot's
Decking Stain ($30/gal) on the deck. I found that a brush is better
than spraying, but I know that's not what you wanted to hear.
I get the impression that you don't want to invest the time or money
to do the job the right way. If you change your mind here's the
1. Wash the deck. (never use a pressure washer on soft wood!!) Use
Jomax, bleach and water in a garden spray. Use a long handled car wash
brush. Rinse with plenty of water. Follow up with a deck brightener
if you want to remove the grey.
2. Wait 5 days for the deck to dry.
3. Apply a thin coat of stain. Use a natural brisstle brush. (not a
sprayer!!). Apply on cool/shady surfaces and spread it thin.
4. Repeat 1-3 every 2-3 years.
You'll get much better protection using a lightly pigmented stain.
(Olympic Natural, Cabot Clear Solutions, Sikkens SDR, Benwood, etc).
Thompson's is total garbage. Behr is close.
I did the same. On the vertical surfaces it is not so bad, but the
horizontal surfaces peeled away in a year. You'll never see a Cabot can in
I have used Cabot's Decking stain and have not seen any peeling at
all. Cabot's lasts 5X longer than Thompson's. After 3 or 4 years it
needs to be reapplied, but I have not recoated under the deck at all.
If you don't use Cabot stain, then what do you use?
