How to fixing a cracked concrete slab in outdoor shed?

[SilentNoise1]

  

Hi I have small shed in my backyard. There are two cracks on the concrete slab. Could you please advice the best and cheapest way to fix this?

I am thinking off filling the gap with concrete mix and resurface the floor with cement.

Any suggestions

Hi @SilentNoise1 

In order to repair such a large crack in your concrete floor, I suggest using Lanko 20kg 173 Floor Leveller in combination with Bondall 1L BondCrete Cement Additive. I propose trying this technique, I suggest using a medium sized thick plastic bag and filling it with mixed mortar and using it as a piping bag so that the mortar can seep deeply into the crack.

Several applications will be necessary, I recommend giving the first application enough time to cure before applying the second topping. When the crack is full of mortar and reaches the surface, I recommend using a trowel to level it with the floor.

As for the part of the floor with the worn-out surface, I recommend using the same products, read carefully the mixing instructions when used as a floor surface repair compound.

Please make sure to wear personal protection such as gloves, goggles and a dust mask when working on your floor repair.

If you have any other questions we can help with, please let us know.
