Westminster Stamped Concrete seals concrete for homes across Westminster. The sealer we use is a clear coat that we roll or spray onto the concrete, and it helps keep water, oil and salt out of the slab. We seal the new slabs we pour, and we reseal older stamped, stained and plain concrete. We look at your concrete and write you a quote before any work starts.
Sealing new concrete and resealing old concrete
On a new slab we pour, we let the concrete dry out before the first coat goes on, and we tell you the day we'll come back to seal it.
On older concrete, we check how well the old sealer is holding up. One simple test we use is to drip a little water on the slab. If the water beads up, we leave the sealer alone, and if it soaks in and turns the concrete dark, we put on a new coat.
If the sealer on your stamped concrete has gone patchy, cloudy or white in spots, we strip the old coat before we put on a new one. Then we clean the slab, so the new sealer sticks to the concrete, not to dirt.
Picking a sealer
We use a few kinds of sealer, and we help you pick the one that suits your slab.
- Wet-look sealer. The wet-look sealers we use sit on top of the concrete and leave a shine, and they make the color on stamped and stained concrete look deeper.
- Penetrating sealer. The penetrating sealers we use soak into the concrete instead of sitting on top, so the surface keeps a plain, natural look with no shine.
Some of the sealers we use are solvent-based and have a strong smell while they dry. When we seal a garage floor with one, we keep the garage door open while we work and until it dries. The EPA says VOCs are gases that come off certain solids or liquids, and it says to increase ventilation when using products that give off VOCs.
Not the black coating used on asphalt
Sealcoat is the black coating some homeowners have put on asphalt driveways, and we never put it on concrete. We work east of the Continental Divide, where USGS says the coal-tar-based kind is mostly used. USGS says coal-tar-based sealcoat is a potent source of chemicals called PAHs, and that coal tar and coal-tar pitch are known to cause cancer in people. It also says car tires and snow plows wear the coating down to a fine dust, which gets washed or tracked into soil, streams, lakes and house dust.
Cleaning water and the storm drain
Before we seal, we wash the slab. The EPA says rain that runs off hard surfaces goes straight into a storm drain, with no soil, plants or water treatment plant to filter it first. So we keep the cleaning products and the dirty water out of the street and the gutter.
What to get in writing
Ask for these in writing, whoever you hire:
- The name of the sealer, and whether it is solvent-based or water-based.
- How many coats you are getting.
- How the slab will be cleaned, and whether old sealer will be stripped first.
- Where the wash water will go.
- When you can walk on it, and when you can drive on it.
Questions about concrete sealing in Westminster
How much does concrete sealing cost?
We price each job once we've seen the concrete, and you get that quote in writing. Our price moves with the size of the area, how much cleaning or stripping it needs and the sealer you pick.
How often should I reseal my concrete?
We base it on the sealer we use and how much sun and traffic your slab gets, and your written quote from us says when we'd suggest the next coat.
Will sealer make my pool deck slippery?
The wet-look sealers we use can be slick when they're wet, so on the pool decks, steps and walkways we seal, we mix a fine grit into the last coat for better grip under bare feet.
Can you seal concrete another company poured?
Yes, we can seal concrete that someone else poured, as long as the slab is solid. If it has sunk or broken up, we look at stamped concrete repair or a stamped concrete overlay first.
Will sealer fix cracks in my concrete?
We can't close a crack with sealer, because the clear coat we use goes over the crack and it still shows. We can fill small cracks before we seal.
How does sealer help in a Westminster winter?
The sealers we use help keep melted snow and salty water from soaking into the slab. The City of Westminster says residents have to clear all snow and ice from the sidewalks within 24 hours of the end of a storm, so on a sealed walk or driveway, we suggest a plastic shovel blade so you don't scrape the sealer off.
Do I need a permit for concrete sealing?
Before we start, we call the City of Westminster's Building Division at 303-658-2075 about your job, and we tell you who will apply for any permit it needs. The city says homeowners who live in the home can do the work and apply for the permits, and that if you hire a contractor, the contractor must be signed on to the permit.
Do you seal concrete outside Westminster?
Yes, we do. We also seal concrete in Arvada, Broomfield, Thornton and Northglenn.
