- Concrete cracks
- Masonry joints
- Vertical cracks
The vertical-and-overhead counterpart to a self-leveling sealant. Use it on foundation, wall, and masonry cracks where the filler needs to stay put while it cures.
Pros
- Non-sag body stays put on vertical and overhead cracks where self-leveling sealant would run out
- No primer needed on concrete, brick, or masonry and it bonds to many other substrates
- Flexes with +/- 25% joint movement and is paintable to match surrounding surfaces
Cons
- Must be tooled by hand to a smooth finish, unlike a self-leveling product
- Rated to about 3/8 in joint width without backer rod, so it is not for very wide cracks
- Full cure takes roughly a week, so it is not a quick same-day repair
