How are you vibrantly coloring old or new interior/exterior concrete.

I am curious as to the current market trends.

How are you vibrantly coloring old or new interior/exterior concrete, polymer modified cementitious overlayments, and micro-toppings ...

** hydrocloric reactive acid stain

** acetone based stain

** solvent based concrete dye

** water based stain/dye

** soy based stain

** "beer" based stain

** polyaspartic/PAP stain & sealer/PAP combo

*

Do you apply all, some, or focus on only one of the above. 

** If you are applying primarily reactive stains, when/if needed do you use dyes to touch up/bend in areas that didn't react for whatever reason? 

** Do you feel as if in the modern day "green safe" (environmentally conscious) world that the public "perception" of anyting containing the word "acid" is steering this segment of the decorative concrete industry in new directions?

** Do your customers have tunnel vision on the cost per sq.ft. at time of the decorative concrete surface  application (selecting water or solvent based acrylics) ... "or" longer life, ways/means of lowering their floor maintenance budgets, gloss/color retention (paying more up front, less down the road as years go by) when it comes to the higher peforming types sealers applied over the decorative concrete to shield/protect them (100% solids epoxies/indoor only, aliphatic urethanes/typically exterior, or indoor/outdoor PAPs? ... good, better, best order)
