If you have decorative brickwork around your home, odds are that sooner or later you will have to deal with a recalcitrant brick that decides to let go of its mooring.
Not only is this problem unsightly, but it can be dangerous if it occurs on a step or walkway.
The standard repair procedure of resetting the loose brick with new mortar mix does, of course, do the job, but can be a bit of a hassle. It is sometimes tough to remove the old mortar and can be tricky to mix the new material to the proper consistency.
As a quick, easy alternative to the old method, try this technique. The only material you will need is clear silicone sealant, available at any hardware store.
First, make sure that the loose brick and its anchor point are both completely dry and swept free of any loose debris. Do not remove any old mortar that is still bonded to the bricks.
