Tuck pointing brick involves replacing damaged mortar between bricks to maintain structural integrity and appearance. Here’s a step-by-step guide on how to do it:
Preparing for Tuck Pointing
Before you start, gather your materials, including:
- Mortar raking tool: For removing old mortar.
- New mortar: Choose a type that matches the existing mortar.
- Trowel: For applying mortar.
- Jointing tool: To finish the mortar joints.
- Stiff brush: For cleaning up excess mortar.
- Safety glasses
- Gloves
- Dust mask
Step 1: Remove the Old Mortar
Use a mortar raking tool to remove the crumbling and deteriorated mortar. The reference states "Remove the crumbling mortar with a mortar raking tool". You need to remove enough old mortar to allow the new mortar to properly adhere, usually to a depth of about 3/4 inch. This step is crucial for ensuring the longevity of the tuckpointing.
Step 2: Mix the Mortar
Prepare the new mortar according to the manufacturer’s instructions. Ensure you have a consistent and workable mix. Avoid making it too wet or too dry.
Step 3: Applying New Mortar
Use a trowel to carefully push new mortar into the empty joints. The reference notes "Fill the joints by pushing new mortar into the joints." Be sure to fully fill the gaps, packing the mortar tightly to avoid air pockets. You can use the trowel to make sure there is enough mortar in the joint for the finishing.
Step 4: Finishing the Joints
Use a jointing tool to create a finished look, matching the existing type of joint. "Finish the joint with a jointing tool to match the existing type of joint" the reference explains. For example, you might use a concave jointer for a concave joint.
Step 5: Clean Up
After the jointing is done, use a stiff brush to clean away any excess mortar from the brick faces. "Once the finishing is complete, brush off the excess mortar with a stiff brush" the reference says. This step is important to keep the brick surface clean and to make the tuckpointing look professional.
Key Considerations
- Mortar Matching: Try your best to match the old mortar color, texture and composition to blend in and maintain a unified look.
- Weather: Tuckpointing should ideally be done in dry conditions with moderate temperatures to prevent the mortar from drying too quickly or not setting properly.
- Safety: Wear safety glasses, gloves and a dust mask for protection while working with mortar.
- Practice: It can be helpful to practice the application on a less visible section before moving to the main area.
By following these steps, you can successfully tuck point your brickwork, restoring its structural integrity and visual appeal.
