How do I remove silicone from the cracks in my driveway?

Hate to tell you that physical removal is all you can do. Silicone is pretty resistant to solvents. Rake it out of the crack, grind it, wire brush, etc. Next time spend the money on a good urethane caulk.

Yep! What Cruiser said. A wire brush works pretty well, if you don’t mind adding some elbow grease to it. : ))

Wow….hated to hear that! Sounds like WORK…thanks guys!

I don’t understand the problem. If the silicone fills the cracks, and if you let it cure properly before driving over it, then it won’t ‘stick’ to anything. What’s on your tires now will wear off soon enough. I’d leave it be.

the silicone adheres to the black off my tire…looks bad… it did cure, but the cracks show black.

@CyanoticWasp Much of the Big Box silicones are now cheapend formulas that have been let down with liquid fillers to extend the silicone polymer and these liquid extenders can creep out of the cured polymer creating this sticky film especially in hot direct sunlight. And add to the equations hot rubber tires and you get this trade of tacky residues that @BoBo1946 is experiencing. Pure frustration when I found out that my supplier knew of this and didn’t tell us the whole story about this trend to cheapen their products.

@Cruiser I did that years ago at another house and it was never a problem. Looks like crap….as you say, people cut corners now days.

@BoBo1946 This just happened about 3–4 years ago. You can still get 100% solids silicone that meets Military specs but it is pricier and not as easy to come by. I would still use the Urethanes for exterior sealing applications.

@Cruiser It caught me by surprise. It looked really good and it had cured, but when I drove my car over it….wow…

Thank you…next time I check that out Cruiser!

Thanks, @Cruiser. That’s good to know, since I’m using silicone sealer on through-hull fittings on the new boat.

it’s going to be one of those mind numbing tasks to be left on the back burner. That stuff is crazy hard to get out of a crevice but it can be done.

Actually, now I’m thinking that if it’s permanently tacky, it might be a good idea to cover it with some fine sand that will stay in place in the tacky material.

Put a new driveway in. ;-)
