Fresno Fun: The Up-Sides
- Speed Demon: Fresnos are time machines for large areas. Think driveways, patios, even that ambitious sidewalk you're building to avoid the grumpy neighbor's sprinkler (we've all been there).
- Smooth Operator: Fresnos excel at creating a uniform, polished finish - perfect for that sleek, modern aesthetic.
Fresno Faux Pas: The Down-Sides
- Seal the Deal (Maybe a Bit Too Well): Fresnos can seal the surface prematurely, trapping water and air bubbles – not ideal for our freeze-thaw happy winters here. This can lead to nasty things like spalling (think concrete chips breaking off) – and let's face it, nobody wants a driveway that looks like it went through a bad breakup with a jackhammer.
- Not for the Faint of Trowel: Exterior concrete often uses air-entrained concrete, which has tiny air bubbles for better freeze-thaw resistance. Fresnos can disrupt these bubbles, reducing that very resistance.
So, Can You Fresno Your Exterior Concrete? Maybe... with an asterisk.
Here's the deal: It can be done, but with caution. Here are some tips for the adventurous DIYer:
QuickTip: Use posts like this as quick references.
- Wait for It: Let the concrete stiffen up considerably before unleashing the Fresno. You want the bleed water (surface water) to disappear first.
- Lighten Up: Fresno with a gentle touch. Don't go all Michelangelo on your patio – a few passes are enough.
- Consider Alternatives: For exterior concrete, a broom finish might be a better option. It creates a textured surface that's slip-resistant and allows for better drainage.
Remember: Consulting a professional concrete contractor is always your safest bet. They'll have the experience and know-how to ensure your exterior concrete looks stunning and lasts for years to come.

How to Achieve a Broom Finish?
A broom finish is created by drawing a stiff-bristled broom across the concrete surface before it fully hardens. This creates grooves that provide traction and drainage.

How to Avoid Spalling? Proper curing is key! Keep your concrete moist for several days after pouring to prevent cracks and spalling.
