Coatings, Part 1
Paint is a bad word. There is no money in “paint.”
There is tremendous profit in “exterior coatings.”
Please understand that this “exterior coatings” business
is fraught with calamity for many honorable contractors. Sears

home - several inches down - and prime and coat below ground level.
A high pressure water jet is used to remove all the loose anything
that is stuck to the walls. Workmen then dig out the cracks and
fill the cracks with elastic rubbery stuff. The “stuff”
will sticks to stucco. The “stuff” also expands and
