Installing brick veneer on an exterior wall can add beautiful character and curb appeal to a home. With the right planning and preparation, it is a project a motivated DIYer can take on. Here is a step-by-step guide to installing brick veneer on an exterior wall.
Planning Your Project
Before you start installing the brick, take time to carefully plan the project. Here are some key steps:
- Evaluate the wall surface – Brick veneer can be installed over wood framing, masonry block, or poured concrete walls. Ensure the surface is in good condition.
- Choose your bricks – Consider aesthetics and availability. Popular options include clay, concrete, and manufactured stone veneer.
- Determine brick pattern – Look at examples online or in your neighborhood. Consider a running bond, stack bond, or decorative pattern.
- Calculate needed materials – Factor in total square footage to be covered, mortar, and 10% extra for cuts and waste.
- Check local building codes – Get any required permits and ensure lath installation meets code requirements.
Proper planning will make the installation process go smoothly.
Preparing the Wall Surface
Once you’ve completed the planning phase, you can move on to preparing the wall for the brick veneer:
- Clean surface thoroughly and make any needed repairs – Fill any cracks or holes and ensure the surface is structurally sound.
- Apply weather resistive barrier – Tyvek or other wraps provide a water-resistant layer under the brick. Staple carefully in place.
- Install metal lath – Use corrosion resistant lath with a minimum 2.5 lb/sq yd weight. Staple every 6-8 inches.
- Apply mortar scratch coat – Mix mortar and trowel 1/2 to 3/4 inches thick to embed lath. Let cure 1-2 days.
Proper lath installation is key to providing a sturdy base for the brick veneer.
Installing the Brick Veneer
Now comes the fun part – putting up the actual bricks. Follow these tips for success:
- Mix mortar – Use Type S mortar. Mix well but don’t overwater. Let rest 10 minutes before using.
- Apply mortar to wall – Use the scratch coat as your guide. Apply 1/2 to 3/4 inch thick mortar.
- Install bottom row bricks – Set corner bricks first. Apply mortar to brick backs. Check row for level.
- Install subsequent rows – Use lines and spacers to keep everything straight and evenly spaced. Stagger vertical joints.
- Cut bricks as needed – Use a wet saw or chisel. Smooth cut edges so they aren’t visible.
- Let mortar cure – Allow 24 hours between rows. Keep mortar moist while curing. Avoid freezing temps.
Take your time, periodically cleaning excess mortar and verifying level. The attention to detail will pay off.
Grouting and Finishing Touches
The brick veneer installation is complete, but there are still a few final steps:
- Allow mortar to fully cure – Wait at least 3 days before grouting. This prevents issues with efflorescence.
- Mix grout – For best results, use sanded grout in a color that matches your mortar.
- Apply grout between bricks – Force it into joints using a rubber grout float or trowel. Wipe away excess.
- Clean surface – Use a damp sponge in a circular motion. Avoid smearing grout on brick faces.
- Seal bricks – Once dry, apply a sealer formulated for masonry. This adds protection.
- Caulk edges – Use an elastomeric sealant where veneer meets siding or trim. Tool into joint.
Stand back and admire your work! With proper planning and care, your new brick veneered wall will add curb appeal and value to your home for years to come.
Frequently Asked Questions
What size bricks should I use?
For exterior installation, 4 or 2-1/4 inch standard size bricks are recommended. Larger bricks may be too heavy. Avoid thin veneer bricks meant only for interior use.
What about electrical boxes or conduits on the wall?
If possible, relocate them before installing the brick. If not, carefully cut bricks to fit around them, leaving a gap for displacement. Caulk around openings.
Can I install brick veneer over vinyl siding?
Yes, furring strips can be applied over vinyl siding to create a more stable surface for the lath and mortar to adhere to.
How long does the project take?
The total time depends on the size of the area, but plan for 1-3 full weekends for most DIYers to complete all steps.
Should I hire a contractor?
For very large projects or if you lack experience, hiring a professional mason is advisable. They can also assist if structural issues are discovered.
