Dan,
I have no experience with this particular product, however I looked at
the site and the descriptions. This looks very much like a typical
elastomeric or LBC (Lead Barrier Compound). My best luck with any of
these is on masonry surfaces (block and stucco), however, condition of
the substrate is everything and verification of proper thickness of
application is very difficult. We used FiberLock a number of times in
the middle, late nineties. It is similar in finished thickness and
elasticity and is applicable by spraying, The product is warranteed for
twenty years. It holds small deteriorated substrates well (good
bubbles, Guinness Book blisters) and rips or peels like a skin where
moisture has been an issue. The thickness poses other problems. You
need a carpenter to refit all the friction surfaces (windows, doors) so
that after application the fit is right. It will hide your problems
longer, but ask the representative what to do when you have to repaint
if for some reason it does not last forever as they claim. In general,
I think it is probably a poor choice for wood and needs a careful look
for historic work as it is not very reversible.
Let's hear from MikE on this. By the way, Edison Coatings
products have been used on an almost finished terra cotta façade
restoration in (you guessed it, New Haven!) and look fabulous. The
color match and glazed look are the best I have seen to date.
Best,
Leland

Subject: Coating analysis interpretation
We historic district staff in North Carolina are starting to see
requests in historic districts for a regionally advertised product,
"Spray-on Siding," from a company named Alvis Coatings, Inc. based in NC
("ALVIS Spray On Siding is a special blend of resins and polymers that
are designed to look like fresh paint but endure like siding."). It was
very hard to get any technical data on what exactly it is. They have now
posted some ASTM test data on their website. I am wondering if anyone on
the list would care to look at this info and interpret the numbers for
me. It would be greatly appreciated. Scroll to the bottom of the page
for the test data.

The other question I can't get any info on is methods of surface
preparation and application. It could be the greatest thing since sliced
bread but if they have to blast the surface to get it to stick, that
would be bad. So I'll keep poking around on that issue.
Thanks,
