Short answer
For heavy mirrors or TVs on brick, the most reliable anchors are:
- Sleeve anchors (3/8" or 1/2") set directly into solid brick (not mortar)
- Lead lag shields with lag screws (5/16"–3/8") in solid brick
- Chemical/epoxy anchors with threaded rod (plus mesh sleeves if brick is hollow) for very heavy loads or questionable brick
Avoid plastic anchors, drywall toggles, or fastening into mortar joints for heavy items.
Why these anchors work
Brick is brittle compared to concrete, so you need anchors that spread force without exploding the brick. Sleeve anchors and lead shields expand gradually and grip the wall of the hole. Chemical anchors bond the threaded rod to the brick, offering high strength and vibration resistance—great for big TVs or thick/heavy mirrors. Concrete screws (e.g., Tapcon) can work, but they have lower capacity and require more fasteners to share the load.
Key principles:
- Drill into the brick, not the mortar. Mortar is weaker and can crumble under sustained load.
- Distribute the load across multiple bricks. Use at least 4 anchors for TV brackets; 2–4 for mirrors depending on weight and cleat style.
- Mind brick type. Solid brick accepts sleeve/lead anchors well. Hollow/cored brick often needs chemical anchors with mesh sleeves.
Tools and materials
- Hammer drill + carbide masonry bits (sizes matched to your anchors)
- Anchors: 3/8" sleeve anchors, or 5/16"–3/8" lead shields + lag screws, or chemical anchor kit (structural epoxy, mixing nozzle, gun), threaded rod, washers/nuts, mesh sleeves for hollow brick
- Level, tape measure, pencil
- Vacuum, blow bulb/compressed air, wire hole brush (for epoxy)
- Sockets/wrenches; torque-limiting driver preferred
- PPE: safety glasses, dust mask/respirator, hearing protection, gloves
- Optional: blue painter’s tape for layout, masking for dust, helper for lifting TV/mirror
Choosing the right anchor by scenario
- 65" TV (~40–80 lb) on a fireplace/chimney (solid brick): 4 x 3/8" sleeve anchors or 4 x lead shields with 3/8" lag screws. Embed at least 1.5" into brick.
- Large mirror (60–120 lb) using a French cleat on solid brick: 2–4 x 5/16" or 3/8" sleeve anchors or lag shields, spaced over multiple bricks.
- Unknown or hollow brick: Chemical anchors with mesh sleeves and 3/8" threaded rod. Use at least 4 attachment points for a TV.
Typical targets (verify product instructions)
- Sleeve anchor (3/8"): 3/8" bit; min embed 1-1/2"; edge distance ≥ 2-1/2"
- Lead shield (3/8"): 5/8" bit; embed full shield length; use 3/8" lag screw
- Concrete screw (1/4" or 5/16"): 3/16" or 1/4" bit; embed ≥ 1-1/4" (capacity lower)
- Chemical anchor: Hole diameter per adhesive spec; embed 6–10× rod diameter (e.g., 2–4" for 3/8")
Step-by-step (solid brick with sleeve anchors or lead shields)
- Plan and mark
- Position the bracket or cleat level. Mark holes centered in bricks, at least 1.5–2" from brick edges. Avoid mortar joints.
- Drill
- Use a hammer drill and the correct bit. Tape the bit for depth. Drill straight and to full embedment depth. Keep steady pressure to avoid wallowing the hole.
- Clean holes
- Vacuum, blow out dust, and brush if available. Clean holes greatly increase holding power.
- Set anchors
- Sleeve anchors: Insert through the fixture if possible, then tighten until snug (do not over-torque).
- Lead shields: Tap shield flush in the hole, align fixture, install lag screw with washer; tighten until firm.
- Mount and tighten
- Hang the mount/cleat, install all fasteners loose, verify level, then snug evenly.
- Hang the TV or mirror
- Use a helper. Double-check that the bracket’s safety catches or cleat engagement are fully seated.
Step-by-step (hollow/unknown brick with chemical anchors)
- Mark and drill as above.
- Insert mesh sleeves into each hole if the brick may be hollow.
- Clean holes thoroughly (blow-brush-blow) 2–3 cycles.
- Inject adhesive from the bottom up until 2/3–3/4 full.
- Insert cut lengths of threaded rod with a twisting motion; ensure embedment depth is met.
- Cure per adhesive spec (typically 20–60 minutes depending on product and temperature).
- Mount hardware with washers and nuts; tighten snugly.
Safety and best practices
- Wear eye, ear, and dust protection. Masonry dust is harmful—use a respirator if drilling many holes.
- Keep anchors away from edges and corners of bricks to prevent cracking.
- Do not over-torque; brick can spall. If the anchor spins or the hole feels soft, move to a new location.
- For brick veneer over wood framing, loads are limited by the veneer ties. For very heavy items, consider locating studs and using a wall-mount designed to span to framing, or use chemical anchors conservatively.
Tips for best results
- Test-drill a noncritical hole to check for solid vs hollow brick.
- Use a depth stop or tape on the bit to avoid blowing out the back of thin brick.
- For mirrors, a French cleat spreads load and simplifies leveling.
- Use larger diameter anchors (3/8") for heavy TV mounts; spread over at least 4 bricks.
- A hammer drill rental is affordable ($20–$30/day) and makes cleaner holes.
Common mistakes
- Drilling into mortar joints for heavy loads
- Using plastic anchors or drywall toggles in brick
- Choosing too small a diameter or too shallow embedment
- Over-tightening torque-controlled anchors and cracking the brick
- Skipping hole cleaning (reduces pull-out strength significantly)
When to call a pro
- Historic or brittle brick that chips easily
- Mounting over an active fireplace/chimney
- Uncertain wall construction (veneer vs structural)
- Extremely heavy items (>100–150 lb), or where failure risk is unacceptable
Rough cost and time
- Sleeve/lead anchors: $0.50–$2 each (4–6 needed)
- Chemical anchor kit: $25–$40 + $5–$10 for threaded rod and sleeves
- Time: 60–120 minutes for layout, drilling, and mounting
Choose solid-brick attachment points, size anchors generously, and keep torque modest. Done right, a brick-mounted TV or mirror will be rock solid for years.
