Hi, any advice on how I can fix this area of concrete? It is outdoors with a roof but has water flow over it during rain.

Hi @nicole_rose 

Hi that path is  fixable if you wish think about its  repair.

Basically an easy fix with  a little work using some new sand and cement  pre mix and laid on to the old  cleaned and washed cement path giving it a  new surface.

To hold the new cement in  place while it is setting its like a cake mix put into a shaped tin until the cake  rises and is cooked them  we take it off.

The  method:

Along the edge of the concrete we need to put a length of straight timber at the same height as the top of the existing path where it is undamaged. This is our mold .  Hold the timber in place with heavy wood or bricks or pegs. place objects  under the timber at each end to ajdust the height to match the good concrete levels.

We Buy 1  bag of pre mixed Sand and cement from bunnings 

Australian Builders 20kg Sand And Cement Mix Bag I/N: 0760612 $10^.07

You will need waterproof gloves.

Eye protection 

and dust PPE protection as you mix it.

In expensive trowel (or  use a lump of wood later)  Craftright 280mm Plasterers Trowel I/N: 5960138 $6^.98

Buy a  cheap paint stirrer that is used in a  drill will help you greatly. Trojan 100mm Paint Drill Mixer I/N: 0093219  $11^.50

And we can mix it in a bucket with a stick  or a  paint mixer  To  start  with fill half a bucket with sand/cement powder  and  gradually add water  (mix it on a  drill  paint mixer is better and faster adding small amounts of water  100mL aprox at a time to a  toothpaste like consistancy)

Great now wet the concrete path under repair and tip our cement on to it.  Tradies use trowels and can level this area  by eye and you can too.

So  use a trowel or a trowel size lump of  wood

And spread the concrete mixture out filling all the  hollows right up against the timber  edge forrn work.  Once you level the  new concete use  light sweeping  movements to remove any eye sore blemishes try  not to do this for too long.  Often as you moveto take out a blemish you might put in two more  so ligth short strokes and  stop.

Your goal is a  neat flat new concrete surface,   Congrates  job well done.  

Leave the form work in place for a week at least so the concrte hardeness.

Tip  clean up tools asap with  water

Fun  fact

Concreting  taught me how to  mix a  cake and cook it.   One  day I will try  using flour  not cement powder lol
