Tex Cote
Q. I have been solicited by a company called Tex Cote claiming that their texture
coat has a lifetime warranty, bridges gaps up to 1/8" thick and will never
fade, chip, blister or fade. Can you tell me anything about the differences
between a solvent based texture coating and a water based liquid vinyl water
based paint as it relates to its permeability, elongation properties, filling
capabilities, etc. Also, some of these products require a priming bonding agent.
Is the primer always requires for these types of products? I have read up as
much as I can on what type of product is the best but would like to know your
thoughts.
A. Waterborne paints and coatings have matured to the stage where they are
in most cases at least as good as solvent based paints. I cannot tell you specifically
about the comparison of their physical properties, but the company's tech data
sheets should provide this information to you. I am aware that Tex Cote is used
successfully by the Department of Transportation (DOT), and if you need more
info I suggest that you call some of the DOT managers in several states to see
what their experience has been.
Always follow the vendor's recommendations regarding the use of primers. Some
coatings can be applied directly over the substrate, while others need a primer.
Again, if you have any doubts, call the folks at the various state or city transportation
departments for feedback. For the most part you will find them to be very cooperative
and helpful.
Good luck.
Best wishes,
Ron Joseph
