How to buy Terralite stone coating or similar

[Monomial]

I am interested in using a stone coating exterior finish for my house such as Terralite Granite from Terraco.

http://www.terraco.com/products/Stone-Coatings/

Unfortunately, the company does not advertise any kind of a telephone number on their website, and numerous attempts to contact them through their web form have gone unanswered.

Does anyone know where I can purchase this product, or a builder familiar with this technology who will quote a small job for me? I'm looking to do about 18-20 sq.meters. Any product similar to Terralite is also acceptable, but it must be something that simulates the real look and feel of granite with flakes and chips and a jagged finish, not just a poured epoxy with rounded rocks.

Thanks for any advice. The project is in the Rangsit area of Northern Bangkok.
