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 Mount Juliet and Wilson County before installing the new system.

Mount Juliet sits in Wilson County east of Nashville, on Central Basin and Highland Rim transition ground near Percy Priest Lake, another of the fast-growing Nashville-exurb communities that's seen the bulk of its housing built from the 1990s onward. Most garage slabs here are newer poured concrete from planned subdivisions along the Mount Juliet Road and Central Pike corridors, generally consistent but still finished with standard builder-grade sealer rather than anything rated for long-term durability. The town's proximity to Percy Priest Lake keeps humidity somewhat higher in lake-adjacent neighborhoods than in the drier parts of Wilson County further out, and Middle Tennessee's freeze-thaw winter pattern applies here the same as across the rest of the Nashville basin. Mount Juliet's older, pre-boom homes near the original town center are a small minority against the newer subdivision stock that now defines most of the city.

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.
