Arvada Concrete Sealing

Run the arithmetic on a driveway the way we do. It gets placed one time. Over the next twenty-five or thirty years it gets sealed somewhere between eight and a dozen times, if the owner keeps up with it. Every one of those coats is a small line on a small invoice. Together they're the difference between a slab you replace once and a slab you replace twice.

That's the whole value argument for sealing, and we'd rather make it in years than in adjectives. Nobody looks at a freshly sealed driveway and feels good about the money. The payoff is invisible on purpose: it's the scaling that didn't happen, the joints that didn't ravel, the apron that's still square. We seal new work, old work, patios, walks, and shop floors all over Arvada.

What you're actually buying

Water is the enemy and everything else is a detail. Concrete is porous. Water gets in, carrying road salt and fertilizer and whatever else was on the surface, and then the temperature crosses freezing and comes back, which happens dozens of times a winter here. Each cycle expands what's in the pores and pushes the paste apart from the inside out. You see it as scaling, as dusting, as an edge losing a grain at a time.

Two chemistries, and which one belongs on which surface

Penetrating sealers, the silanes and siloxanes, soak in and react down inside the concrete. Nothing sits on top, so the look barely changes, traction doesn't change, and a shovel blade has nothing to catch on. That's what goes on driveways, walks, RV pads, and anything that gets cleared hard in winter. It's also what we'd pick if somebody could only afford one surface, because it protects the most square footage per hour of labor.

Film-forming products, mostly acrylics outdoors, sit on the surface, deepen color, and add sheen. That's what a stamped or colored patio needs, since color is worth protecting and worth showing off. The tradeoff is that a film scratches, can get slick when wet, and eventually has to be stripped rather than recoated forever. Indoors, urethanes and epoxies do heavy duty on shop and garage floors where sun isn't a factor. Putting a film-former on a plowed driveway is one of the most expensive mistakes in this trade, because the only way back out of it is stripping the whole thing.

The bill for skipping it, stage by stage

What a sealing day includes when we do it

• Moisture test on the slab, because sealing damp concrete is the number one way these jobs fail
• Full clean: degrease the oil, pull the organic staining, rinse, then let it dry all the way through
• Test whatever is already on there, since new product over a failing film goes down with it
• Two thin coats rather than one heavy one, because a thick film can't breathe and will lift
• A written return date, so the next coat gets booked before anything starts to look wrong

What moves the price, and when we do the work

Square footage is the smallest part of it. What moves a sealing quote is condition: how much cleaning and degreasing the slab needs, whether an old coating has to come off, and how much hand detail there is around steps, edges, and joints. A clean drive out around Candelas or Whisper Creek is close to a straight coating job. A patio in one of the older neighborhoods carrying thirty years of grill grease and a failing film in the traffic path is mostly labor.

Timing comes down to a dry slab, mild temperatures, and dry weather on both sides of the work. Our best windows are late spring and again from late August into October, and fall is the favorite because the slab goes into winter protected. We won't seal during a February warm spell no matter how pleasant the afternoon feels, since the concrete is still carrying snowmelt and the product won't cure at those overnight temperatures. New concrete waits 28 days at minimum, longer for some products and longer still if it went down in cold weather. And on any slab in its first winter, no deicers, sealed or not.
