Should I Seal My Concrete After Pressure Washing?

A Guide for Colorado Homeowners in Aspen, Basalt, and the Roaring Fork Valley

Living in the Colorado Rockies is nothing short of stunning — but if you own a home in Aspen, Basalt, or anywhere in the Roaring Fork Valley, your concrete surfaces face a brutal yearly cycle of snow, salt, sun, and freeze-thaw conditions.

That’s why pressure washing alone isn’t enough.

If you’re not sealing your concrete after cleaning it, you’re leaving it vulnerable to permanent damage.

Why Sealing Concrete After Pressure Washing Matters

When you pressure wash a driveway, patio, or walkway, you’re removing the grime, mildew, and stains that build up over time. But you’re also exposing bare concrete to the elements again.

Without sealing, you risk:

• Cracking and flaking from freeze-thaw cycles

• Staining from rust, oil, or leaves

• Water absorption that weakens the slab

• Spalling and surface erosion over time

In a high-altitude climate like Aspen or Snowmass — where we see wild temperature swings and long winters — sealing concrete is more than cosmetic. It’s protective maintenance.

How Long After Pressure Washing Should You Seal?

We recommend sealing 24 to 72 hours after washing, depending on weather conditions and surface dryness.

👉 Pro Tip: If you’ve recently had your surfaces cleaned by Aspen Pressure Washing, we’ll handle the timing and prep — but if you're doing it yourself, make sure your concrete is completely dry before applying a sealant.

What Finish Should I Choose — Matte or Wet Look?

This mostly comes down to personal preference:

✅ Matte Finish

• Low-sheen, natural look

• Popular for walkways, natural stone, and patios

• Best for homeowners who don’t want a shiny surface

✅ Wet Look Finish

• Enhances color and texture

• Adds a subtle gloss or shine

• Great for decorative concrete, stamped patios, or darker surfaces

📌 We always ask our clients up front which they prefer. If you're not sure, we're happy to show sample photos from jobs we’ve done in Aspen, Basalt, and Glenwood Springs.

🎨 Application Tools: What You’ll Need

To apply your concrete sealer effectively, here are the essentials:

Paint Rollers

• Purdy 4-Pack 9" x 3/8" Nap White Dove Roller Covers

  
  

  Best for: Smooth to semi-smooth surfaces

  
  

  (Check Lowe’s for current pricing)

• Valspar 3-Pack 9" x 1/2" Nap Roller Covers

  
  

  Best for: Textured surfaces like broom-finished concrete

Roller Frame

• Project Source 9" Metal Standard Paint Roller Frame

  
  

  (Durable and reusable — check Lowe’s for pricing)

Extension Pole

• Project Source 3-ft to 6-ft Telescoping Extension Pole

  
  

  Perfect for reaching across patios and avoiding back strain.

Bucket

• United Solutions 5-Gallon Plastic Paint Bucket

  
  

  Use for mixing and transporting sealer safely and easily.

Pump Sprayer (optional)

·       Any two-gallon sprayer

Can be used to spray sealer, but you would also want to back roll with the paint rollers. Not essential and adds an extra step unnecessarily. Wind would be a factor to keep in mind.

🛠️ Extra Application Tips

• Surface Prep: Pressure wash and let fully dry before sealing- 18+ hours is preferred to ensure concrete is totally dry before application of the sealer.

• Weather Matters: Ideal application temp: 50°F–80°F. If it rained in the past 18 hours, or will within 24 hours of apply sealer, reschedule when you do this type of work.

• Even Coverage: Use overlapping strokes to avoid puddling

• Drying Time: Follow product instructions (typically 24–48 hours) before walking or driving on the surface

• 
  

When and How Often Should I Reseal?

In Colorado, most homeowners should reseal every 1–3 years, depending on:

• Snowmelt exposure

• Vehicle traffic

• UV intensity at elevation

• Previous sealer quality

Test your surface: If water no longer beads on top, it’s time to reseal.

Timing Your Project in the Roaring Fork Valley

• Aspen & Snowmass: Higher elevation — start late May to early June

• Basalt & Carbondale: Earlier warmups = mid to late May is fair game

• Glenwood & New Castle: Possibly seal as early as April (if it’s dry!)

Always check the 3–5 day weather window. Avoid applying before expected rain.
