Resurface a Concrete Retaining Wall: Tips and Mistakes to Avoid

Being able to resurface concrete walls, is an aspect of property maintenance that can be attempted by any home or business owner, because it is not a hard task, and it can save a bundle of money when doing it yourself. Even though the process is simple, there are a few common mistakes that are made, and in order to resurface concrete walls effectively, you need to be aware of them before beginning the task.

Clean the Cracks and Chips

Use a chisel and a stiff wire brush to remove all of the loose material from within the cracks and chips. The new concrete that is spread on will not be able to fill and bond to the wall if it is full of dust or cement particles, because it will form a paste, rather than staying at the proper consistency.

Pour Concrete Into Cracks and Chips

Before beginning the actual resurfacing project, pour some mixed concrete into the cracks and chips, so that they are completely filled. Do not wait until you are actually resurfacing the area to try and fill them with a trowel. The entire area has to be fixed, by filling the crack or chip with cement, before trying to resurface concrete walls.

Sweep the Resurfaced Concrete Wall

After the wall has been resurfaced properly, sweep it with a stiff push broom, to remove any burrs and excess amounts. If you do this after the cement has hardened, but before it sets, it is easy and will not cause any marks. However, if you want a design to the wall, use the broom to work the specific texture into the wall before it dries. Do this while removing the problem areas.
