Asphalt Crack Sealant
Asphalt crack sealant fillers come in three main types: Asphalt Emulsion, Elastromeric, and Acrylic Crack Sealant.
It is often advised by the asphalt industry that if the width of the crack you are facing in your blacktop driveway is 2 inches or more, you should approach repairing it as you would repair a chuckhole in the asphalt.
A narrower crack can be fixed using a pourable crack filler.
Before you attempt to use any of the cracks in the blacktop, you should ensure that the crack is clean and dry with no soil or vegetation in it before the work begins.
Of the three different types of crack fillers, asphalt emulsion, elastromeric, and acrylic crack sealant, the asphalt emulsion is the least expensive.
Elastromeric crack sealer, like Owens Corning TruGuard, is a bit pricier and can cause slight irritation if too much of it gets on your hands. However, it lasts longer, generally speaking, than asphalt emulsion as a crack filler.
Acrylic crack sealant can last slightly longer than elastromerics but costs, on average, a bit more.
As an other option for filling the cracks in asphalt, you can consider a new product category called crack stixs. To repair a crack in the blacktop, you break off properly proportioned width of crack stixs and place the product into the crack.
Once the product is on the crack, you need to melt the product with a specifically formulated (such as Bernz-O-Matic) torch. When the stixs have melted, the repair is done.
