How to Caulk for Masonry

Over time, masonry used in landscaping can crack or chip and need repair. Caulking cement repairs the damaged part and provides a water barrier that prevents the cement from cracking further. A mortar and cement caulk is recommended for this application because it can withstand the harsh environments that masonry undergoes. All the essential supplies can be acquired at your local home improvement store.

Things You'll Need

• Clean household rags or towels
• Utility knife
• Caulking gun
• Mortar and concrete caulk
• Putty knife
• Dish soap and water

Instructions

1. Clean, wash and remove all loose masonry from the area and allow it to dry fully.

2. Put the caulking tube into the caulking gun and secure tightly.

3. Cut the tip of the caulking tube to make a 1/8-inch to ¼-inch-wide bead of caulk.

4. Start caulking by gliding the caulk gun along the length of the affected area. Then stop the flow of caulk and clean the tip with a wet towel.

5. Use a finger dipped in soapy finger to push the caulk into the joint. This will make a tight seal and uniform surface.

6. Use a wet rag and a putty knife to clean any remaining caulk.
