Driveway sealer and crack filler

Steve-Maine · Jul 30, 2014

I"m going to hire my driveway sealed and some cracks filled. What would be a good sealer to use. I asked this question last year but forgot. I have heard latex sealer isn"t that good. Also should the cracks be filled with hot tar? Thanks

Hello Steve-Maine,

Hot tar would be a good choice. I just did mime yesterday and I filled the MINOR cracks with cold tar. It looks good so far HA! HA! Your winters are pretty cold in your neck of the woods! So hot is my recommendation,

Guido.

Steve,
when you factor sealing a drive each year, would it be cheaper in the long run to use concrete?

If you are going to seal your driveway with the stuff that comes in a five gallon bucket, then you would be better off with cement. The best way is to chip seal it. It will last on a driveway for better then ten years if you take care of it. The oil goes down on the drive way at 350 + degrees and the stone is spread on top. They put it on gravel roads in Wi. and it will last a long time. The road in front of my house has been sealed twice and it looks like a blacktop road.

You are way off the oil they use to chip and seal is an emulsion which means it is run through a mill and has water and chemicals emulsified into asphalt and runs around 180 degrees on average, that is what is normally run through a distributor (sprayer) truck and the steam you see is the water flashing off as it is sprayed.

The only time you see 350 degrees is in hot mixed asphalt and even that is getting on the high end for temperature usually 300-325 degrees is the norm for hot mix.

Yes emulsion is at 180 degrees but if you can find a company that uses hot oil which is pure asphalt that is cut with fuel oil and heated up over 300 degrees and sprayed on the driveway and covered with stone it will last longer then using emulsion, because the hot oil will crack and when it gets hot will blend back together, where emulsion will not blend back together but stay cracked.

I came across an ad for crack sealer awhile back that came in a block. It came with a little propane heater on wheels, and after heating it up you pour it on/into the crack, then as it cools it hardens, though it is still flexible. It is intended for municipal use, but I can see that it would be very durable.

Steve, I seal coated for several years. Make sure your company uses coal tar instead of asphalt base sealer. Coal tar is gasoline resistant. Also, make sure there is sand in the mix. I doubt if you will want to pay for hot tar, any crack filler from Loews or Home Depot will work just fine. Ellis
