Mexicali Pool guy

Dear Friends, Let me present myself: I started in Mexicali Mexico a swimming pool construction company in 1984 (25 years ago) named "Albercas Aquarius" I started from zero knowledge of the swimming pool construction experience, just after watching the construction of one 15 X 30 in ground swimming pool. Practice, mistakes and time made me improve this knowledge, and after almost 600 s. pools made in Mexicali, I was so tired (stressed) that I stopped doing this for 2 full years. I am a Medicine Doctor with specialization in Acupuncture and electrotherapies. The medicine and the s. pool made me almost crazy... because the working guys at the s. pools were asking for sand, gravel, plaster, etc. and I was working as a Doctor. Well to make a long fable short... I quit the s. pool construction this 3 last years, but yesterday I talked to a good friend (and co-worker in the S. Pool building) and told me he resigned at the s. pool company he was working, and since I made a "Corporation" in USA for the working of this building, he offered to be partners, and he will find the jobs and I will be in front of the company. I read all your tread on this plaster theme, really interesting (both of you guys) and I agree with almost all of your telling about plastering... the real smart part of the s. pool that can end in a good work or in a disaster (doing the job again, and again) My question since I used for plastering ONLY white cement, poolmix and water... and today days I discovered the plastering is using agregates ( 3M colorquartz) and I do not know the correct proportions of blue, cayman (green), black, for a good blending color (And as saying from the 3M web page more duration and resistance) AND the white cement and poolmix? I will greatly appreciate your income on this matter. Alex
