Caulking Foundation settling cracks then adding stucco to match the existing finish.
Hello, all were explaining how to apply caulking stucco walls hairline cracks. Enjoy.
FYI, folks, as I mentioned in this video, once the loose stucco is removed, the stucco crack is cleaned well.
If you apply or fill that foundation crack up with Sika-a Flex polyurethane adhesive sealant, the foundation can still flex because of the rubber expansion joint called Sika-A Flex.
I don’t believe there is stronger caulking that adheres to porous things such as bricks or blocks as concrete back together sold in the United States.
But remember all, nothing adheres to a dusty or dirty surface not this caulking or even cobwebs.
Sikaflex 1a Kit – One Component, Flexible, Non Sag, Polyurethane Concrete and Masonry Sealant, I’ve been using this caulking for over 30 years because it never fails me.
Just don’t get any of this sticky strong nasty stuff on your hands. I wear my stucco gloves when using it, myself.
Cracking stucco walls are due to” Thermal Expansion.” That’s expansion and constriction, and yes, it’s not only common but normal.
