Concrete Staining & Sealing in Richmond

Unsealed concrete absorbs water, and in Michigan that water freezes, expands and pops flakes off the surface a little more each winter. Road salt speeds the chemistry, so the driveways and walks along the M-19 and Gratiot Ave frontages spall first in Richmond. The ranch driveways from the postwar decades show what sixty unsealed winters do; the newer drives at the edges are still sound, and sealing them now is the cheapest thing that will ever be done for them.

Well water adds a reason of its own. Iron-bearing spray from sprinklers and hose bibs soaks into bare concrete and bonds in the pores, which is why the rust arcs on Richmond driveways get darker every year. On a sealed slab the same spray sits on top, and the next cleaning takes it off with far less work. For anyone with irrigation fed by a private well beyond the city mains, sealing is the difference between a stain that cleans and a stain that sets.

Three finishes cover the range. A penetrating sealer soaks in with no gloss and no change in traction, which is the right choice for driveways, walks and the aprons along the busy frontages. A decorative sealer adds a satin or wet look and keeps the pattern crisp on stamped patios. Full staining gives a plain slab real color under a protective topcoat, and the concrete porch slabs and steps on the older blocks around Beebe St are the usual candidates. Every finish goes on only after a full clean, rust treatment and drying time, because sealer over dirt or old failing sealer clouds and peels within a season.

How Seal Jobs Fail

Almost always at the prep. Sealer rolled over dirt, algae or a rust arc locks the stain in and clouds above it. Sealer on top of an old film-forming coat that has begun to peel peels along with it. A film-forming product on a driveway that takes salt all winter along Main St goes hazy and slick by February, where a penetrating sealer would have soaked in and stayed invisible. Sealing a slab still damp from the wash turns it milky, and sealing new concrete before it has cured traps moisture that should have left. We clean, treat, strip and dry before a drop goes down.

Timing It Right

Late spring through early fall, on dry days with the temperature in the product's range and no rain in the forecast for a day after. Spring works once the salt is washed off the driveways along Main St and Gratiot Ave. Late summer is the best window for the newer homes at the edges, when a driveway poured in spring has finished curing and the weather is settled. Do not wait for the first frost: a slab sealed in early October has protection through the winter that matters most, and one sealed in November often does not cure.
