Basement floor coating & sealing

Sometimes, and the test tells us. Vapour drive through a slab can be handled with a vapour barrier primer. Active water coming in through a wall or a footing cannot, and coating over it just traps it. We test before we quote, and if the answer is that you need drainage first, that is what we will tell you.

Because most Seacoast basement slabs were poured before vapour barriers were standard, and moisture moving up through concrete is the single most common cause of a coating lifting. The test takes a few days and costs a fraction of laying the floor twice.

As little as we can engineer. Almost all of our commercial work is phased — one bay, one zone or one room at a time — so the whole facility is never down at once. We agree the sequence and the hand-back times at the walk-through and put them in the proposal, which means you can plan around a number rather than a promise.

Foot traffic roughly 10 to 14 hours after the last coat, vehicles, racking and equipment after 24 to 48 hours, both at 70°F. A cold slab is slower and we will tell you the real figure for your building rather than the data-sheet one.

Yes, and on most commercial jobs that is how we prefer to run it. Off-shift work is normal scheduling for us rather than an exception we charge extra to accommodate. Holiday and summer shutdown windows are the easiest of all to plan against.

In a heated interior, year-round — and winter is often the best time to book institutional and municipal work, because the building is quiet and our calendar is not competing with the summer rush. Polyaspartic systems install down to about 30°F with the slab 5°F above dew point. You may see −40°F claimed elsewhere in this industry; it is not supported by any manufacturer data sheet we work from.

Nearly every failure we are called in to replace comes down to one of three things: the slab was acid etched or not prepared at all, nobody tested it for moisture, or the joints were coated over instead of being repaired. We grind or shot blast to a measured profile, we test and record moisture and dew point before anything goes down, and we treat joints as a separate detail.

About an hour on site. We test the slab for moisture, look at the joints, the drains and the thresholds, ask what gets spilled on the floor and what cleans it, and talk through when the space can realistically be released. You get a written scope with a system recommendation and a phasing plan. There is no obligation and no pressure to decide on the spot.
