Asphalt Sealing

[Ohiosam]

My church's 17,000 ft sq parking lot needs sealed and I got a couple bids. They're close, $250 apart. The lower bid will brush it on, the higher bid spays it on. Brush guy says his method is better, of course spray guy says his is better. I have gravel so this is something I know nothing about. Are the final results of either method different in any way? TIA

Interested in replies. Mine needed done when I bought the place...12 years ago

Ask them how many gallons are included in the estimate and the application rate. I would go with the higher rate. More material equals better finished product. The spray guy is going to do the job much faster but will it be better quality and same amount of product used?

The main/only virtue of brushing instead of spraying is that agitating the wet material (with brush or roller) on the substrate does force material into small cracks and such whereas spraying will not do that.

Not needed for other than aesthetics and line striping. They do not use it in hi-ways or public roads

That has always been my line of thinking.

The only reason to seal asphalt is if the slope of the asphalt is too flat for proper drainage of water off of the asphalt. 2.00% slope is what we design for to prevent bird bathing of water on the asphalt.

In my experience, brushing usually lasts longer than spraying. The spray coat guys always seem to use the bare minimum… just enough to get full coverage and nothing more. I also suggest you get two coats. Not just one.

Not true. All asphalt cracks given time. Crack sealing is very common along with micro sealing, chip sealing, and overlays. Sealing asphalt will make it last longer.
