Blackstone griddles are popular for outdoor cooking, and many users want a more permanent, stylish surface by installing blackstone bricks around the cooking area. This approach protects the frame, improves heat control, and gives the station a clean, finished look.
Below you will find a practical guide with material choices, build steps, design options, and maintenance tips to create a durable brick layout that fits your Blackstone griddle.
| Brick Type | Heat Resistance | Installation Effort | Cost Range |
|---|---|---|---|
| Firebrick | Very High | Moderate | $$ |
| Refractory Brick | High | Moderate | $$ |
| Clay Paver Brick | Medium | Low | $ |
| Concrete Brick | Low | Low | $ |
Planning Your Blackstone Brick Layout
Choosing Brick Materials for Heat and Weather
Selecting the right brick material is essential for safety and longevity around high-heat surfaces. Firebrick and refractory brick are best for direct heat exposure, while clay paver bricks work well for outer borders and decorative edges.
Consider how much weather exposure the bricks will face and choose materials rated for outdoor use to prevent cracking, spalling, or discoloration over time.
Measuring and Design Sketch
Measure the perimeter of your Blackstone griddle and sketch a layout that leaves small gaps for thermal expansion. Plan a border that is at least four inches wide for stability and airflow management.
Use graph paper or a digital tool to map out brick courses, ensuring cuts are minimized and patterns remain consistent across corners and edges.
Preparing the Base and Frame
Level Ground and Concrete Pad
A level base prevents uneven settling and keeps the brickwork stable. If the ground is soft, set the griddle on a concrete pad with a compacted gravel base and landscape fabric to control weeds.
Allow the concrete to cure fully before placing the Blackstone griddle and beginning brick installation to avoid cracks and shifts later on.
Installing a Metal Frame or Stand
Some users prefer a metal frame behind the brick surface to add structural support and a clean line where the griddle meets the bricks. Stainless steel or powder-coated frame pieces resist rust and heat warping.
Attach the frame securely to vertical legs or existing structure, ensuring it is plumb and aligned with your layout lines before setting the first brick course.
Setting Bricks and Mortar Techniques
Mortar Mix for High Heat
Use a heat-resistant mortar mix designed for fireboxes and outdoor installations. Standard cement mortar can crack under repeated heat cycles around the griddle.
Lay down a consistent bed of mortar, comb ridges with the notched edge of a trowel, and place each brick firmly to create a strong bond without trapping excess air pockets.
Building Sturdy Courses
Start from the corners and work toward the center, staggering vertical joints for strength. Keep a consistent joint width, usually about 3/8 inch, for both structural integrity and a polished appearance.
Check horizontal level and vertical plumb after every course, adjusting as needed before the mortar sets to avoid a wavy or uneven finish that looks unprofessional and can trap debris.
Finishing, Sealing, and Long-Term Care
Curing and Cleaning the Brick Surface
Allow the mortar to cure completely, typically 48 to 72 hours, before lighting any fires on the Blackstone. Clean excess mortar haze with a soft brush and water once the mortar has begun to harden but is not fully set.
Rinse the bricks after cleaning to remove any residue and let the surface dry before applying a sealer if you want extra protection against grease stains and weathering.
Key Takeaways for Building Blackstone Brick Surrounds
- Choose heat-resistant brick like firebrick or refractory for areas near the griddle.
- Measure carefully and sketch a layout with expansion gaps and consistent joint widths.
- Prepare a level base or concrete pad to keep the brickwork stable over time.
- Use heat-resistant mortar and stagger vertical joints for strong, attractive courses.
- Cure mortar fully and clean the surface before sealing to protect against grease and weather.
FAQ
Reader questions
Can I use regular concrete bricks around my Blackstone griddle?
Regular concrete bricks are not ideal because they can crack under high and repeated heat. Choose firebrick or refractory brick for the areas closest to the griddle, and reserve concrete bricks for outer decorative borders that see less direct heat.
How far should the brick surround extend from the griddle frame?
Extend the brick surround at least four to six inches from the outer frame of the griddle. This gap provides room for thermal expansion, allows airflow, and gives you space to work with tools during installation and future maintenance.
Do I need a special mortar when installing bricks on a Blackstone setup?
Yes, use a heat-resistant mortar mix designed for fireboxes and outdoor installations. Standard mortar can degrade over time when exposed to the repeated high temperatures produced by the griddle.
What maintenance routine keeps brickwork looking good around the griddle?
Clean the bricks regularly with a soft brush, mild detergent, and water, avoiding harsh acid cleaners that can erode the surface. Reapply a penetrating sealer once or twice per year to protect against grease absorption and weather damage.
