Poured concrete vs.Skimstone vs concrete board?

I've wanted poured concrete counters in the kitchen for some time. Only two thing prevent it...Budget and husband's willingness. So I search high and low for a product called Skimstone and finally found it. Not sure if it's be cost prohibitive but instructions sure look labor intensive....SO...I saw a remodeling show that use the concrete board above a fireplace and the ole wheels & gears started spinning. If they could use it as a decorative element and it's used in bathrooms....Why can't I use it on my kitchen counters w/ heavy coating of (water proof) sealent?????
