Maintaining Masonry in Construction

Regular Inspection

Routine checks help you identify issues early on. Inspect your masonry every 6 to 12 months, paying attention to:

• Cracks in mortar joints
• Loose or displaced bricks
• Signs of water damage
• Efflorescence (white powdery substance on bricks)

Cleaning Techniques

Gentle Cleaning

Start with the least aggressive method:

• Use a soft brush to remove loose dirt
• Always test cleaning methods on a small area first
• Avoid using acidic cleaners that can damage the bricks and mortar

Pressure Washing

If more intensive cleaning is needed:

• Use low to medium pressure settings (below 700 PSI)
• Keep the nozzle at least 12 inches away from the surface
• Move the nozzle continuously to prevent concentrated damage

Repair Techniques

Repointing

Repoint deteriorating mortar joints to restore integrity to masonry walls:

• Remove old mortar to a depth of about ¾ inch
• Use a matching mortar mix for aesthetic and structural consistency
• Apply new mortar in layers, allowing each to set slightly before the next

Crack Repair

Address small cracks promptly to prevent them from spreading:

• Use a masonry sealant for minor cracks
• Inject epoxy into larger cracks for added strength
• Consult a professional for severe or structural cracks

Preventative Maintenance

Prevention is key to maintaining masonry:

• Ensure proper drainage to avoid water accumulation
• Apply waterproof sealants where appropriate
• Check and maintain roof and gutters to divert water away from masonry surfaces
• Prune nearby vegetation to allow airflow and prevent moisture retention

Recommended Practices

Adhere to these best practices to keep masonry in top condition:

• Avoid using de-icing salts on masonry surfaces during winter
• Update maintenance records to track inspections and repairs
• Consult with a masonry expert for issues beyond routine maintenance

Additional Steps in Masonry Maintenance

Dealing with Discoloration

Bricks may experience discoloration over time due to certain elements like moisture, dirt, algae or mold. Here’s how to manage them:

• Use a solution of bleach and water to treat mold and algae growth.
• For hard water or rust stains, a commercial cleaner is recommended. This should be carefully chosen not to contain acid that can corrode the masonry.
• Always rinse thoroughly after applying any cleaning solutions to avoid residue build-up.

Control the Damage from Frost

Frost can be detrimental to your masonry. It can cause bricks to expand and contract which eventually leads to frost damage or frost heaving. To counter this:

• Consider frost-resistant bricks for construction in frost-prone areas.
• Applying a breathable sealant on the bricks can also provide a good layer of protection while allowing the brick to “breathe”

Working Around Shrubs and Vines

Plants like shrubs and vines can add aesthetic value to your masonry construction, but they can also become a cause for concern. Here’s how to handle these vegetation types:

• Prune the vines regularly – this helps to prevent them from working their way into the mortar joints.
• Be cautious about removing old vines that are already embedded in the mortar, as this can damage the bricks.
• For shrubs, ensure they always remain well-trimmed and at a safe distance from your bricks.

Filling Larger Gaps Misrepresented as Cracks

Sometimes, what appears to be a crack might actually be a larger gap. Here’s how to handle this situation:

• Use foil-back foam as a filler and then apply a masonry caulk over the foam. Remember to tool the caulk joint to ensure it bonds properly and looks neat.
• Contact a masonry professional if the gap is significant as it could indicate a more serious structural problem.

Masonry Repair Techniques

Replacing Damaged Bricks

Damaged bricks can compromise the structural integrity of masonry walls. Here’s how to effectively replace them:

• Chisel out the damaged brick carefully to avoid affecting adjacent bricks.
• Clean the cavity to remove debris and old mortar.
• Prepare a mortar mix that matches the original in composition and color.
• Insert the new brick, ensuring it sits flush with surrounding bricks, and fill the joints with fresh mortar.

Surface Coating Repairs

Surface coatings can protect and rejuvenate brickwork. These include:

• Stucco: Applying stucco can offer a fresh look while protecting the brick beneath.
• Paint: Only use breathable masonry paint to avoid trapping moisture, which can damage brickwork over time.
• Sealants: Applying a high-quality, breathable sealant can protect your brick from water penetration and other environmental factors.

Installing Expansion Joints

Expansion joints help manage the natural expansion and contraction of masonry materials. Consider the following:

• Determine the areas where thermal expansion could cause cracks, such as large wall sections or where materials meet.
• Install flexible expansion joint materials that can accommodate movement without cracking.
• Ensure that the placement and spacing of expansion joints meet the recommendations provided by masonry standards.

Flashing Installation

Flashing redirects water away from vulnerable areas in masonry structures:

• Apply step flashing around windows, doors, and roof areas to prevent water infiltration.
• Use drip edges along the roofline to guide water away from bricks and mortar.
• Regularly inspect flashing for wear and tear and replace it as necessary to maintain its effectiveness.

Brick Stitching

Brick stitching stabilizes walls with severe cracks:

• Insert stainless steel rods into the wall across the crack.
• These rods are grouted in place and stitched across the crack, providing structural support.
• This method distributes loads evenly and reinforces the wall without replacing entire sections.

Maintaining Masonry Tools

Cleaning Tools After Use

Proper cleaning extends the life and performance of masonry tools. Follow these steps after each usage:

• Rinse off tools with water immediately after use to prevent mortar and cement from hardening.
• Use a wire brush to scrub any remaining residue for stubborn spots.
• If necessary, use a mild detergent or specially formulated masonry cleaner to remove ingrained dirt and contaminants.

Proper Storage Techniques

Storing masonry tools correctly prevents damage and wear:

• Store tools in a dry location to prevent rust and corrosion.
• Hang trowels, hammers, and chisels on pegboards or store them in toolboxes to keep them organized.
• Ensure that power tools like mixers and grinders are covered to protect them from dust and moisture.

Regular Maintenance Checks

Frequent inspections keep tools in optimal condition:

• Check handles of hammers, trowels, and other hand tools for cracks or splinters.
• Examine power cords and plugs for damage; replace any frayed or broken cords immediately.
• Lubricate moving parts, such as the gears in brick saws and mixers, according to the manufacturer’s guidelines.

Sharpening and Repairing Tools

Sharp tools enhance efficiency and accuracy:

• Sharpen trowels, chisels, and other cutting tools regularly using a file or sharpening stone.
• Replace worn-out blades on brick saws to ensure clean cuts.
• Fix or replace damaged handles on hand tools to maintain safety and usability.

Inventory Management

Keeping an organized inventory of your masonry tools helps in efficient project planning and tool longevity:

• Maintain a checklist of your tools and their condition.
• Use color coding or labeling to identify specific tools and their designated storage spots.
• Perform periodic audits to ensure all tools are accounted for and in good working condition.

Conclusion: Ensuring the Longevity of Masonry Through Proper Maintenance

Undeniably, masonry upkeep requires consistent inspection, meticulous cleaning, minor repairs, and preventative maintenance to ensure its longevity.

Regular checks about every six months can identify early damage like cracks in mortar or loose bricks. Cleaning should be gradual, always opting for the least aggressive method first and avoiding acidic cleaners.

Maintenance involves techniques like repointing deteriorating mortar joints for structural soundness and attending to small cracks promptly to prevent them from escalating. Preventative practices like the application of waterproof sealants and periodic roof and gutter maintenance should not be understated.

Similarly, professionals should be consulted for significant issues beyond routine cleaning and maintenance.
