A new coating cannot be applied over a failing old coating — the old material must come off completely. Contractors in our network remove peeling, bubbling, or delaminated garage floor coatings for homeowners and businesses throughout Hendersonville and Sumner County before installing the new system.
Hendersonville sits along the shore of Old Hickory Lake northeast of Nashville, on Central Basin limestone soil that's been reshaped by decades of lakefront and near-lake subdivision development since the reservoir was built in the 1950s. Much of the housing stock here is mid-century and later, with garage slabs poured from the 1960s onward, though lakefront humidity runs consistently higher than in Nashville's drier inland neighborhoods, keeping moisture vapor moving through concrete for more of the year. Newer construction has pushed east toward Indian Lake and the Highway 31E corridor, on graded fill that's more consistent than the older lakeside lots but still subject to the same Middle Tennessee winter freeze-thaw swings. The lake's proximity also means higher humidity and occasional flooding-adjacent moisture issues for garages built close to the shoreline, a factor that doesn't apply the same way in Nashville proper.
Why Old Coatings Must Come Off
Applying a new coating over a failing old coating transfers the adhesion problem — the new coating bonds to the old coating, which is not bonded to the concrete. The result is that both layers fail, usually sooner than the original coating did. Proper removal and preparation is the only way to ensure the new coating achieves the mechanical bond with the concrete that makes it last.
How Old Coatings Are Removed
Diamond grinding removes failing coating material and profiles the concrete surface simultaneously. This is faster than chemical stripping and produces a better surface profile for re-coating. Once the old material is removed and the concrete is profiled, the floor is ready for new coating installation. Your contractor will assess the concrete condition after removal and flag any cracks or spalls that need repair before the new system goes down.
