Work commenced February 2009. Concrete re-surfacing performed by All Concrete Coatings is very poor workmanship, breaking up, discolored greatlty from one area to the other, did not provide joint sealant on all joints, those not with joint sealant are covered over with concrete coating now breaking up. Warranty does not apply to any of this as well as nothing covered under warranty by company. Went to BBB and filed complaint. No resolution reached by BBB, All concrete Coating and myself. Beware of All Concrete Coatings.com...not good workmanship or warranty coverage. read full review »
