DIY hot asphalt driveway crack repair experience?

rrr1234October 8, 2011

I've tried the many cold pour crack fillers, but they all fail after one season (here in northern CA). Looks like the only way to do it right is for a hot repair, but the equipment appears only available to the pros. I'm thinking of buying a propoane stove, a cast iron pot and some blocks of commercial hot crack filler (in solid blocks), then melting them down in the stove+pot and hand pouring into the cracks. Has anyone done this? Any suggested ways to keep the cost down?

I have seen the 'Crack-Stix' product, but not sure if this is as good as doing the pour technique? Any thoughts on this?

I've had some success with using 'foundation tar
coating' on the cracks. It skins over but doesn't
got hard and brittle, like the crack repair in a

You know the filler is flammable when melted?

Exactly what brickeye said! This isn't a DIY job unless you are willing to risk third degree burns. If you overheat the filler, you'll have it flash over into flames. Just like a grease fire, the worst thing you can do is to try to put it out with water. The resulting major fireball explosion will take out anything within a 50 foot radius. That includes you. Even if you keep your head and use a fire extinguisher, you ruined the batch. And, if you don't heat it up enough, it won't adhere properly.

This is a job that takes an experienced pro to do safely.

I recently tried the Pli-Stix, (Dalton Enterprise) product which I bought at Home Depot. It takes a while and I am still learning but it does do a good job.

There are some tricks to this some of which I learned from the Amazon web site from buys who also have used this stuff.

1) It is pretty time consuming to apply. So it is easier on your back if you can sit on the drive way. So pick a warm day you will be there a while.

2) It is essential that you get the right blow torch. I used a Benzomatic TS 8000 from Home Depot. I chose this because it used MAP gas (less important) and it was REGULATED (very important). Regulated is essential because you will be holding the torch at an angle to heat the road If the torch is not regulated, it will cough and die out as the liquid gas reaches the torch. The other solution is to use a gas hose so that you can keep the gas bottle uptight. The instant on feature really helps too.

3) Wear gloves and eye protection when using the torch

4) The temp affects Pli Stix. I was using it on a warm day and in the sun it behaves like play dough. SO you can stretch it to push it into cracks. It also becomes very sticky. You want it to stick to the road not your hands and tools. I had a bucket of water which I dipped my hands into and the screw driver I was using. This keeps the stuff from sticking so that you can stuff it into the crack.

5) Cutting pli stix was tricky for me. I think because of the temp. It tends to stick. If you need to cut it into strips keep it cool. It is less sticky. Also dip your tool into water, or use some silicon or WD40 on the cutter.

6) Stuffing into cracks takes a while, this is the slowest bit of the job. Hence if you can sit it really helps. Large cracks are easy. Thin cracks is a screwdriver job, and using your hands. Remember to keep them wet to avoid sticking.

7) The easiest bit was the blow torch bit. Keep the flame moving so not to burn. You want to melt not burn. I found I could do about 6 inches at a time in about 10 seconds or so depending on crack size.

8) Super thin cracks I am still trying to figure out. Some people say cut the Pli Stix length wise. I tried but I think the product was too warm on the day I was using it and it stuck to the blade and was not easy to cut.

9) The final seal looked great and very durable. Only time will tell. So far looks much better than the other products which I tried. All the other products failed over the winter

Best, Mike.

It's been a few years since you applied the Pli-Stix. How did all the effort turn out? Did it last thru the winter?
