Fixing the slab before the coating goes on
Everything in this category happens before the resin does, and it decides whether the resin holds. A coating is a thin film. It follows the shape and the condition of whatever is under it, and it will not bridge a moving crack, hide a spall or bond through oil.
Cracks come in two kinds and they get treated differently. Static cracks and control joints that are not moving get filled rigidly, ground flush and coated over, which is what a crack filler kit is for. Moving cracks are a different problem. Filling a live crack rigidly means it comes back through the finished floor, usually within the first season. Diagnose which one you have before you buy material for it.
Spalls, pits and chipped edges need a patch that can be shaped and sanded rather than a liquid filler. Fast setting body fillers and patch compounds do this well because they can be feathered and ground flush within the same shift, which keeps the schedule intact.
Contamination is the other half of this category. Oil, grease and tire marks do not come off with pressure washing alone, and a degreaser that pulls contamination out of the pores is the step that stops a fish eye or a bond failure. Solvents belong here too, both for wiping down and for cleaning tools and equipment before the resin sets in them.
The honest counter advice on acid is that mechanical preparation is the better path. Acid etching is inconsistent across a slab, it does nothing to oil, and it leaves residue that has to be neutralized and rinsed completely or it interferes with the coating. Acid still has a place for specific cleaning and etching tasks, but it is not a substitute for grinding a floor you intend to coat. The rest of the category is the supporting cast that a crew notices only when it is missing. Scrapers, wire brushes, drop cloths, mixing containers, respirators and gloves. None of it is glamorous, and every one of them stops a job cold when it is not on the truck, usually at the worst possible moment, which is the reason experienced crews stock these items by the job rather than by the piece.
What to check before you order
- Determine whether each crack is static or moving before choosing a rigid filler
- Check the cure time of the repair material against when you need to grind it flush
- Confirm the repair or patch material is compatible with the coating going over it
- Match the cleaner to the contamination, since a degreaser and an etchant do different jobs
- Check solvent compatibility with your resin before using it as a wipe or a thinner
- Confirm ventilation and personal protective equipment requirements for acids and solvents before they reach the site
Crack Repair & Accessories: common questions
How do you repair cracks in concrete before applying a coating?
Concrete cracks are repaired before coating by opening and cleaning the crack, filling it with a rigid repair resin or filler kit, then grinding the repair flush with the slab so the coating passes over it evenly. Moving cracks need a joint treatment instead, because a rigid fill will telegraph back through.
Will a crack come back through an epoxy floor?
A crack will come back through an epoxy floor if the slab is still moving at that crack, because a thin resin film cannot bridge structural movement. Static cracks filled rigidly and ground flush generally stay hidden. Live cracks and control joints should be treated as joints, not patched over.
Do I need to degrease a garage floor before coating it?
Yes. Oil and grease soak into concrete pores and stop a coating from bonding, and pressure washing alone does not remove them. Use a concrete degreaser to pull contamination out of the slab, rinse thoroughly, let it dry, then grind. Grinding alone will smear deep oil rather than remove it.
Is acid etching a good way to prepare concrete for coating?
Acid etching is a weaker option than mechanical grinding for coating preparation. It etches unevenly across a slab, does nothing to oil or existing coatings, and leaves residue that must be fully neutralized and rinsed. Diamond grinding gives a consistent profile and removes contamination at the same time.
What is the difference between a crack filler and a patch kit?
A crack filler is a low viscosity resin that flows into a narrow crack and cures rigid, while a patch kit is a shapeable filler used to rebuild spalls, pits and broken edges. Fillers are poured and ground flush, patches are troweled, shaped and sanded.
What solvent is used to clean up epoxy before it cures?
Uncured epoxy and polyaspartic are typically cleaned from tools and equipment with acetone or xylene, chosen by how fast you want the solvent to flash off. Once the resin has cured, solvent will not remove it and mechanical removal is the only option, so clean tools immediately.
