Surface Prep & Repair · Bayport, MN · Est. 2003
Bayport is a St. Croix River town in Washington County between Oak Park Heights and Lakeland, on Highway 95 with the river on one side and the bluff on the other. Andersen Corporation has been the town's largest employer for more than a century and the street grid still reflects it. We install polyurea + polyaspartic floor coatings for Bayport homeowners: diamond-ground prep, custom flake colors, 1–2 day install, written 15-year warranty. Early twentieth century worker housing near the plant and downtown, much of it built between the 1910s and the 1940s for people working at Andersen, on narrow lots. Post-war fill behind it, and newer homes up on the higher ground away from the river.
Surface Prep & Repair in Bayport
Bayport is a small town with old concrete, and the housing history explains it. Much of the building near downtown and the Andersen plant went up between the 1910s and the 1940s for people working at the mill, on narrow lots, and the garages that go with those houses are small, detached and unheated, standing on slabs poured at some later point nobody has a record of. Those are the slabs that need reading before they are quoted: older concrete is often thinner, was frequently poured without a vapor barrier, and has usually been painted at least once. The other Bayport fact is the river. The town is on the water, and lower-level slabs downtown and along Highway 95 pass more moisture than the ones up on the bluff behind town, so a calcium chloride test comes before any below-grade quote here. Bayport also has real industrial floor for its size, because the plant and the river ground are here and so are the buildings that serve them.
Bayport has some of the oldest residential slabs on the Minnesota side of the river, and prep here reflects it: paint, patches, thin concrete, spalled edges and river damp, sometimes all on the same floor. We diamond grind to bare concrete, remove failed paint and coatings, repair spalling, fill cracks with polyurea and run a moisture test before quoting an install. Prep on its own is available if you want a sound, clean slab now and a coating later.
Why we don't install epoxy in Bayport
Surface prep is where cheap coating installs get cheap. Acid etching takes 30 minutes with a $40 jug of muriatic acid; diamond grinding takes hours with $30,000 worth of equipment. The cost difference is why some installers acid etch, and the bond difference is why those floors peel. Here's the head-to-head:
If a coating contractor offers to "save you money on prep" by acid-etching, that's the moment to walk away. The prep is the foundation of the install; saving 30 minutes on prep guarantees a re-install in 18 months. Diamond grinding is the only surface prep we do, and it's included in every coating price.
Bayport Pricing
For a coating install, prep is included in the per-sq-ft coating price: never a separate line item, never an upsell. For standalone prep work (sub-contracting to another coating contractor or repair-only jobs), pricing depends on slab condition + scope.

Standalone prep is typically a contractor-to-contractor arrangement, but homeowners with damaged slabs sometimes commission repair-only work as a stopgap before a future coating install. Send photos + scope and Dave will quote.
The 6-step install
Same checklist on every floor. The reason our coatings still look new at year ten when the cheap stuff peeled in year two.
