What does a lifetime warranty on a floor coating actually cover?

Everyone in this industry advertises a lifetime warranty, and almost nobody explains what it covers. So here is the plain version: a coating warranty is a warranty on adhesion. It promises the coating will stay bonded to your concrete. It is not an insurance policy on the floor, and it does not make the floor indestructible. Understanding that distinction is what lets you compare two quotes honestly.

What does “bond failure” mean?

Bond failure is the coating letting go of the slab. It is the thing a coating warranty exists to cover, because it is the only failure mode that is genuinely the installer's fault rather than the world's.

It shows up in three named ways, and they mean slightly different things:

• Delamination — a layer separating. It can be the whole system separating from the concrete, or one coat separating from the coat beneath it. If you lift a piece and the back of it is clean, with no concrete on it, the system never keyed into the slab.
• Peeling — delamination that has progressed to the point where the edges lift and you can pull a sheet or a flap up by hand. Usually starts at an edge, a control joint, or the apron.
• Blistering — domes lifting off the slab, typically from vapor pressure collecting at the bond line. Whether this is covered depends heavily on whether the slab was moisture tested first, which is why the test matters so much.

The mechanisms behind all three are covered in detail in why do garage floor coatings peel. They come down to preparation and moisture, both of which are decisions made by the installer on the day. That is the logic of the warranty: we control the prep, so we carry the risk on the prep.

What do coating warranties typically NOT cover?

Across the industry, these exclusions are close to universal. They are not unique to any one company, and a warranty without them would not be a real document.

Impact and abrasion damage

Drop an engine block, a floor jack, a cast iron pan or a loaded tool chest hard enough and you will chip the coating. That is not a bond failure, it is a collision. Same with dragging a heavy metal shelf across the floor and gouging it, or running a machine with steel wheels over it.

Chemical abuse

Brake fluid, paint stripper, battery acid, aggressive solvents and driveway degreasers left to sit can etch or soften a coating. A splash wiped up is nothing. A puddle left for a week is chemical attack. Warranties normally exclude it, and it is easily avoided.

Structural movement in the slab

This is the big one and it is worth understanding. A coating is a few thousandths of an inch of resin bonded to a slab of concrete. If the slab settles, heaves in a freeze-thaw cycle, or develops a new structural crack, the coating over it will crack too. The coating cannot hold a moving slab together and no coating on the market claims to. Control joints are a related case: joints exist so the slab can move, and movement at a joint can telegraph through the finish. Ask how a contractor treats joints before work starts.

Discoloration from things you put on the floor

Rubber mats, cheap tires, and anything containing certain plasticizers can leave a stain or a shadow on a coated floor over time. Leaving cardboard or a wet mat in one spot for months can also mark it. This is a care issue, covered in how to clean and maintain a coated concrete floor.

Work done by someone else

Coating over another installer's floor, or someone else recoating or repairing ours, generally ends coverage on the affected area. Reasonably so — nobody can warrant a bond they did not create.

How do you compare two lifetime warranties?

Ask for the document, not the adjective. Then read it for these specifics:

• Whose lifetime? Is it tied to you as the original owner, or does it transfer if you sell the house? Both exist in this industry.
• Labor or material only? A material-only warranty means the manufacturer replaces the resin and you pay someone to grind and reinstall it. That is a very different promise.
• Is it prorated? Some warranties reduce what they cover as the years pass.
• Who honors it? The installing company, or a manufacturer you would have to chase yourself?
• What voids it? Read the exclusions list in full. If there is no exclusions list, that is not a stronger warranty, it is a less serious document.
• Was moisture tested and recorded? If the installer did not test the slab, a blistering claim later becomes an argument. A recorded reading protects both sides.

What is Spartic's warranty, specifically?

We carry a lifetime warranty on our floors, and its terms are set out in the written document that comes with your quote. We are not going to paraphrase its exclusions on a blog post, because the document is the document and you should be reading that rather than a summary. What we will tell you is that you should have it in writing before you sign anything, from us or from anyone. If a contractor will not put a warranty in writing, the warranty does not exist.

Why does the prep decide the warranty?

Because an installer can only responsibly warrant what they control. We control how the slab is prepared, and we diamond grind every floor to an open concrete profile rather than acid etching, which is the difference between a coating that is mechanically keyed into the slab and one that is sitting on residue. We control whether the slab is tested for moisture before anything goes down. We control whether flake is broadcast to rejection and whether two clear topcoats go on. Those are the variables that produce bond failure, and they are the variables the warranty is about.
