A spirit level

Step 1: Prepare the support
In order for the repair mortar to hang well, it is essential to prepare your walk.
With the mallet and the mallet, you will open a bleeding on the damaged part of the nose of the staircase.
Then clean the area to be repaired by rubbing it with the wire brush.
If parts of the concrete crumble or come off, do not hesitate to insist on them to take off.
To eliminate dust, vacuum your market.
Step 2: the formwork
For your convenience, it is advisable to install a small wooden form around the step to guide you in your work, and avoid overflowing.
Block your formwork by placing breeze blocks against the wooden planks.
Make sure with the spirit level that your formwork is aligned with the nose of the step.
Step 3: the mortar
Before applying the repair mortar, dip the cavity with a sponge to make it easier to grip.
Then fill the opening by trowel-coating the repair mortar.
Step 4: the finishes
As long as it is still cool, float your mortar so that it is as smooth as possible and that the repair is invisible.
