A corner trowel is a type of specialized tool that can be used to spread mulch, remove weeds and plant bulbs, to lay mortar in wall corners.
They are shaped like a triangle with a sharp edge on one side and a flat end on the other. It features an L-shaped end that allows the user to apply mortar into tight corners, or against obstacles where it would be difficult or impossible to properly apply the product with the standard trowel.
How to use it?
To use it, you should hold it in your hand with your thumb pointing down towards the ground and then drag it across where you want to work. The pointy edge will help loosen up any dirt while the flat edge helps scoop out weeds or soil from hard-to-reach places.
The steps below show how to use a corner trowel properly.
1- Ensure that the wall is firm and dry before applying tile setting material. The best time of year to set tile is during spring or fall when humidity levels are low.
2- Begin by measuring the wall and marking a reference point.
3- Mix your tile setting material according to manufacturer recommendations. Once mixed, use a grout bag or bucket to fill the corner trowel with the mortar product of choice.
4- Position yourself at one end of the corner and place the corner trowel up against it.
5- While applying even pressure with your dominant hand, use the trowel to scoop mortar out of the corner. Apply enough material so it begins to pile higher than the height of the trowel.
6- With your free hand, apply a thin layer of mortar along the wall using either your mud knife or pointing trowel.
7- Hold the corner trowel at a 45° angle from the wall, and use it to scoop mortar from the pile on the floor. Apply pressure with your dominant hand while you pull up and press into position with the corner trowel.
8- Smooth surface of mortar into place using your pointing trowel or mud knife. Allow the mortar to completely dry before proceeding with your project.
In the end, we conclude that corner trowels are useful for planting small plants such as tulips or daffodils close together without damaging their roots too much. It can also be effective when trying to apply mortar in small areas, such as under sinks or between cabinets.
