Question #3: Kiln dried lumber costs
less than PT doesn't it?
Answer #3: Yup. It isn't a wash,
but you will save some on switching from PT to kiln dried,
but spend more in order to seal the kiln dried wood on all
surfaces... but the look will be stunning... and you may
never have to seal it again. You could also take the ultra
safe route and use KDPT (kiln dried pressure treated) which
costs currently about 10% more than PT.
Question #4: What!?! I would not have
to seal it again, as in never? Have you lost your mind?
Nothing lasts that long on wood!
Answer #4: Hey, dude, chill out.
It is true that almost anything you use to seal wood will
need to be re-sealed in 6 months to a year. Understand also
that many factors influence the longevity of this or any
other flouropolymer, but if you prepare the surface correctly,
and apply it correctly, it will last many, many years without
a doubt. And if in 20 years you find it needs a little touch
up in main traffic areas, you can do that with a gallon
of clear or perhaps just a can or two of the aerosol. Touchup
is no problem with this product.
Question #5: You said that this was
an inexpensive alternative. So what might cost a little
Answer #5: Use Ipe for the decking
and railings with 1/2" colored metal balusters for
the pickets and maybe cambera
mahogany for the ceiling. Seal it all (even the metal
balusters) with Super Shield and it will be jaw dropping
gorgeous and stay that way for a long, long time. It will
cost more, but your biggest problem will be keeping your
neighbors from drooling on it!
Question #6: Let's go back to how long
this stuff lasts. You seem very confident.
