Steps

  1. Pick a spot and check for hidden pipes or cables. Keep the fixing away from sockets and switches, and use a detector if you have one.

  2. Mark the hanging points with a pencil. Hold the mirror or bracket in place and use a spirit level so the marks sit level.

  3. Decide on the fixing. Use concrete screws in solid brick or concrete, and masonry anchors for heavier loads or softer block.

  4. Fit a masonry bit that matches the screw or anchor. It is usually the same size as the fixing, so check the packet.

  5. Drill the hole to the depth marked on the screw or anchor. Keep the drill straight and let the bit do the work.

  6. Clear the dust. Blow or vacuum it out of the hole so the fixing grips clean masonry, not powder.

  7. Drive a concrete screw straight in with a socket or impact driver. Stop when the head sits just off the wall.

  8. Or push the anchor into the hole and tighten it with a screwdriver or wrench until it grips firmly.

  9. Hang the mirror on the screws or bolts. Check the level again and tighten the fixings fully.

Tips and common mistakes

Wear safety glasses and a dust mask when drilling masonry, and open a window if you can.

Do not overtighten a concrete screw. It can strip the hole and lose its grip.

For a very heavy mirror, use two fixings and washers, or a French cleat screwed into the masonry.

Drill a test hole in a hidden spot if you are not sure whether the wall is solid brick or hollow block.

Questions

Can I use these fixings on a plasterboard wall?

No. Plasterboard needs a stud or a toggle bolt. The methods here are for brick, block and concrete.

What size drill bit do I need?

Use a bit the same diameter as the screw or anchor. The packet states the size, and a bit too small will stop the fixing going in.

Which is stronger, a concrete screw or an anchor?

Both hold well in solid masonry. Anchors suit heavier loads and softer block, while concrete screws are faster to fit.
