I have had stained concrete work done (not by the linking company) on residential and commercial work and the product looks as good as the day the contractor installed it. Moisture is a concern, but the amount of time your concrete has sat, much of the curing should be done. I've talked to home owners who have done their own. One did have a problem with peeling, the other went well.
