Surface Prep & Repair · St. Paul, MN · Est. 2003
St. Paul is the Minnesota state capital and the largest city we work in, on the east bank of the Mississippi in Ramsey County. It is the closest large city to River Falls and the one the east metro drives into. About 40 minutes west of River Falls on I-94. We install polyurea + polyaspartic floor coatings for St. Paul homeowners: diamond-ground prep, custom flake colors, 1–2 day install, written 15-year warranty. Predominantly pre-1940. Summit Hill, Cathedral Hill, Dayton's Bluff and Macalester-Groveland are 1880s-1920s Victorians, foursquares and bungalows; Highland Park, Como and Battle Creek fill in with 1940s-1960s post-war housing; Highland Bridge, on the old Ford plant site, is new construction from 2019 onward.
Surface Prep & Repair in St. Paul
St. Paul is older than every suburb around it, and it is the one place where the detached alley garage is the normal case rather than the exception. Across Macalester-Groveland, Merriam Park, Summit Hill, Hamline-Midway and Dayton's Bluff, the garage sits at the back of the lot off the alley, holds one or two cars, has no heat, and stands on a slab that is either original to a 1910s or 1920s house or was replaced at some point nobody remembers. Those two facts change the job. An unheated slab has to be coated inside a temperature window, and an old slab has to be read before it is quoted: 1920s concrete is often thin, sometimes has no vapor barrier under it, and can carry a century of oil. Highland Park, Como and Battle Creek are the post-war half of the city, mostly 1940s to 1960s, with attached and tuck-under garages on slabs that grind predictably. Highland Bridge is the newest concrete in St. Paul, poured from 2019 on, and it behaves like any other new build. We diamond grind to bare concrete on all of them and moisture test before quoting any lower-level or tuck-under floor.
St. Paul has more surface prep demand than anywhere else we work, and the reason is age. A hundred-year-old garage or basement slab in the pre-1940 neighborhoods has usually been painted at least once, patched at least once, and cracked from both settlement and freeze-thaw. We diamond grind to bare concrete, remove failed paint and old coatings, repair spalled edges, fill structural cracks with polyurea, and moisture test before quoting an install. Prep alone is available if you want a sound, clean slab now and a coating later.
Why we don't install epoxy in St. Paul
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.
St. Paul 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.

linear ft + sq ft
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.
