A new garage floor doesn't strictly need sealing to survive — but one winter of salty snowmelt dripping off your vehicle makes the case for it. Here's the when and why, without the upsell.
Salt is the enemy
The main thing that ages a garage floor in Nebraska isn't traffic — it's deicing salt. Brine drips off the undercarriage, pools on the slab, and drives chlorides into the surface. Over the years that shows up as scaling, pitting, and dusting. A sealer is a barrier layer that keeps the brine from soaking in.
It's cheap insurance on a slab you just paid real money for.
When to seal
Not right away. New concrete needs to finish curing and release its moisture — sealing too early traps water in the slab and can cause the sealer to fail or haze. Depending on the product and the weather, that wait is typically around a month; penetrating sealers are more forgiving than film-formers.
The practical version: pour in the warm season, let it cure, seal before the first winter. Jerry will tell you when your specific slab is ready.
What kind, and what else helps
For a garage, a penetrating siloxane-type sealer is the low-maintenance choice — it soaks in, doesn't change the look, and doesn't peel. Film-forming sealers and epoxy coatings look sharper and resist stains better, but they're a bigger commitment and want a well-cured, properly prepped slab.
Beyond sealing: hose off the salt slush occasionally in winter, and don't pile deicer on the apron right at the door. Questions about your floor — new or existing — are fair game at a free on-site estimate.
