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 Clarksville and Montgomery County before installing the new system.

Clarksville sits where the Cumberland and Red rivers meet in the Highland Rim, on soils that shift from river-bottom clay near downtown to rockier upland ground toward Fort Campbell. The city's growth has been driven heavily by military family turnover, which means a large share of garages are in newer subdivisions built quickly through the 2000s and 2010s on graded fill, with slab quality that varies noticeably block to block. Older neighborhoods near downtown and along the river have detached garages on original early-1900s pours that have absorbed a century of river humidity. Clarksville's river-valley position traps moisture longer after storms than the open Highland Rim around it, and winter cold fronts moving down from Kentucky bring harder freezes than Nashville sees just an hour south — both of which shorten the life of an uncoated or poorly bonded garage slab here.

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.
