Answers: How do you clean and seal driveway expansion joints?
- driveway expansion joints
- weed removal from concrete cracks
- sealing driveway cracks
- backer rod installation
- concrete joint caulk application
What it concludes
- Preen granules placed in expansion joints prevent weeds from growing by killing them at the root.
- A backer rod should be installed about a quarter of an inch below the lower concrete surface to ensure proper sealant application.
- The Sika self-leveling sealant works well for completely horizontal surfaces with no slope.
- The Tremco Vulkem 45 SSL is recommended for cracks with a slight slope because it will not pool to one side.
- Applying sand on top of wet caulk helps blend the color and prevents windblown debris from sticking to the sealant.
