Epoxy can be one layer
Some professional systems use epoxy for build, adhesion, or working time and then add a different topcoat for UV exposure or wear. Judge the complete build rather than one label.
Sun and temperature change the decision
Direct light near an open garage door, slab temperature, moisture, and seasonal installation conditions can affect whether a particular epoxy product belongs in a Littleton garage.
Compare scope before price
A lower proposal may omit coating removal, edge grinding, stem walls, extensive repairs, moisture mitigation, or a second clear coat. Put each inclusion and exclusion in writing.
The material label is not the complete proposal.
Compare surface preparation, repairs, actual product names, layer sequence, coverage, texture, cure schedule, exclusions, and warranty. A low square-foot figure without those details is difficult to evaluate.
