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.
