Crack and Joint Sealant


  • $125.99

Crack and Joint Sealant (formerly CrackMagik) is just the ticket to stop water infiltration in exterior cracks up to 1/8" in mortar joints on chimneys, brick, or stone walls. It keeps water out where water repellent alone comes up short.

Just brush on with one of the two specially designed brushes included with each container. A half-gallon container will treat the mortar joints surrounding 550 standard size bricks. (Subject to size of bricks, width, and porosity of mortar joints, degree of damage, etc.)

And Crack and Joint Sealant doesn’t significantly change the appearance on most walls or chimneys. It just leaves a slight gloss on dense surfaces. Build-up on brick face can cause cloudy appearance.

With Crack and Joint Sealant you can solve a lot of tough leak problems without the expense of tuckpointing or surface grouting. Manufacturer recommends product be stored where temperatures don’t go below 40° F. Product will solidify when too cold. Comes with a 10-year warranty.


Crack Magic crack and joint sealant makes crack repairs virtually invisible. It will seal cracks up to 1/8" and the application is a breeze with the included brush. Crack Magic comes with a 10 Year Warranty.
