The video discusses how to address the issue of weeds and grass growing in expansion joints and cracks in driveways and sidewalks. The host, Scott, demonstrates a temporary and a permanent solution to the problem.
Temporary Solution:
- Clean out the weeds and debris using a garden hose or a string trimmer.
- Sprinkle Preen, a weed prevention product, into the cleaned-out expansion joint.
Permanent Solution:
- Measure the gap between the concrete surfaces and choose the correct size of backer rod.
- Press the backer rod into the gap, making sure it's tight and about 1/4 inch below the surface.
- Apply a sealant, such as Sika self-leveling product or Tremco Vulcan 45 SSL, to the backer rod.
- Sprinkle sand on top of the sealant to blend it with the surrounding area.
The video also provides tips on how to achieve a smooth finish and how to blend the sealant with the driveway surface.
