We recently purchased and applied the Water Based sealer from Foundation Armor for our 950 sq ft concrete driveway. Couldn't be more pleased with our purchase, their tech support and our results. They answered all our questions before purchase, the delivery was quick, application was easy once I got the concrete cleaned. The product had no odor, it cleaned up easily, and worked well in our new sprayer. Had heavy rains 2 days later and it beaded up just as we hoped for. Looks great. Highly recommend the product and the company.
