Essential
Silane-siloxane penetrating sealer. Best for high-moisture slabs.
- Breathable: vapor can escape
- No film to lift if vapor pressure rises
- Natural concrete look preserved
- 3 to 5 year limited warranty
$800 to $4,500 per project
Basement Floor Coating · Chaska + SW Twin Cities · Owner-operated since 1996
Most basement coating failures trace back to one thing: ignoring vapor pressure from the ground. We test for moisture before we quote, choose the system to match (penetrating sealer for high vapor, polyurea for normal slabs), and prep the concrete properly. The result is a finished basement floor that stays bonded and doesn't bubble or peel at year three.
What we install
Every basement quote starts with a calcium chloride or RH moisture test. The result drives the recommendation: high vapor means Essential, normal vapor opens up Advanced and Ultimate. We won't install a film coating on a slab that's going to lift it off.

$2,400 to $9,000+ per project
Why we moisture-test before we quote
Basement coatings fail at a much higher rate than garage coatings, and the reason is almost always the same: moisture. Without a vapor barrier under the slab, ground moisture migrates upward through the concrete and pushes against any film coating from below. Eventually that pressure wins, and the coating bubbles or lifts. The fix isn't a better coating; it's matching the system to the slab's moisture behavior.
If your basement slab is high-moisture and you want a finished look, the right path is moisture mitigation first, then coating. We'll say so if that's the case.
Transparent Pricing
Basement square footage tends to be larger than garages, so total project pricing scales. The moisture test result, the system tier, and the prep scope (existing paint or coating removal, crack repair) drive the final number. Quote is written and fixed.
Up to ~300 sq ft
~400 to 700 sq ft
800+ sq ft
Removing existing paint, coating, or carpet adhesive adds to prep time. If we find a moisture issue during the test, we'll either adjust the recommendation or walk you through your options before continuing.
The 6-step install
Moisture-aware prep is what separates a basement coating that lasts from one that lifts. Same checklist every job.
