First, does it matter where your Garage Floor Coatings come from? Most contractors do not advertise their suppliers. Most are not exclusive so the same supplier may be supplying 5 or even 10 different contractors in the same area. It does matter. The Slide-Lok product warranties are warrantied by the manufacturer.
Slide-Lok is the manufacturer and they are located in Phoenix, AZ. All the product is made in the USA. Only one contractor in each area can buy material from Slide-Lok as an authorized dealer. Slide-Lok's owner is hands-on involved in the company and in the chemical knowledge of the materials used; not just what they are, but why they are what they are.
Also, the product is consistent from one batch to the next. Everything is tested to make sure. The color pigments and even the flake colors are the same from batch to batch. Per instructions, we always mix batches to eliminate any issues, but we never see any differences to start with.
Warranty: Slide-Lok backs the Lifetime Warranty against yellowing and a 15 Year Warranty against chipping, peeling, etc (bonding issues).
