How to fix cracked concrete?

[VijayWani]

My sideways concrete surface is damaged and I want to fix the same. Please let me know step by step process along with material required to fix the surface of the concrete.

Hi @VijayWani,

Thank you for your question about your concrete.

Unfortunately, I can't quite tell what the issue is as your images are quite blurry. If you could upload some clear images and let me know what the issue is, I am sure I can help out more succinctly.

A good place to start would be to give the concrete a good pressure clean. A pressure cleaner with a surface cleaning attachment like this Gerni 3600 1810PSI 1500W High Pressure Washer would make light work of the job. Check out How To Use A Pressure Washer for some guidance.

If there are other issues that need fixing, please let me know.

Hi Jacob,

Sorry for the blur images. I am uploading new images,

The concrete is damaged and has develped lots of small and big cracks.

Hi @VijayWani,

Unfortunately, cracking is an inevitability when it comes to concrete. That is why you see relief cuts made in concrete. They are there to guide the eventual cracking of the concrete.

Were you just hoping to fill the cracks so they look a bit better, or fix the cracking issue?

There are products that can be used to fill cracks, such as Gripset Betta 1L Concrete Crack Filler, but they do stand out a bit against the existing concrete.

If you were looking to fix the cracking issues altogether, unfortunately, this would likely require the removal and replacement of the concrete.

Let me know what you think.

Hi Jacob,

Thanks for the reply and suggestion. The concrete surface is also damaged. 

Is there any way we can resurface the concrete ? So that It can look better.

Hi @VijayWani,

The first step to making the surface look better is to give it a good pressure clean. This will reveal the extent of the damage to the surface of the concrete.

After cleaning the concrete, you can use a resurfacing product such as Dulux Avista Resurfacing Compound. This resurfacing compound requires cracks to be filled with the Dulux Avista Concrete Crack Repair Kit and the concrete to be etched with Dulux Concrete And Paving Bare Concrete Etch And Clean and primed with Dulux Avista Resurfacing Primer before application.

Have a read through the installation guide for some further guidance on how it works and what is required.

Alternatively, you could always paint the concrete with concrete paint.

Let me know what you think and if you have any further questions please don't hesitate to ask.

Hi Jacob,

Thanks for the solution. It is great. Please correct me the steps if I am wrong.

1. Pressure wash the Concrete

2. Fill the cracks with the Dulux Avista Concrete Crack Repair Kit 

3. concrete to be etched with Dulux Concrete And Paving Bare Concrete Etch And Clean 

4. Apply the primer Dulux Avista Resurfacing Primer 

5. Resurface the conceret using product such as Dulux Avista Resurfacing Compound or use  concrete paint.

Is there any possibility I can use theConcrete sealer with desired colour?

Thanks

Hi @VijayWani,

If you were to use the resurfacing compound, then yes, that would be the correct process.

Yes, you can use the coloured sealer, which is essentially a 3-step concrete paint system.

If you wanted to use the Dulux Matt Concrete And Paving Coloured Sealer, the process would be the same up to step 3, followed by applying Dulux Concrete And Paving Bare Concrete Primer and then your coloured sealer.

Let me know if you have any further questions.

Hi @VijayWani, 

To help guide you through the process, I recommend checking out the Bunnings D.I.Y. advice video How to repair a concrete path. It covers the basic tools and materials you'll need, including a crack filler like Gripset Betta Concrete Crack Filler, a putty knife, wire brush, and optionally a pressure washer for cleaning the area beforehand. You can also use a sanding block to smooth the surface once the filler has dried. The video walks through each step visually, which should make things easier. 

If you’re considering painting or sealing the area afterwards I recommend checking out the Dulux concrete range, which will provide How To application advice for their products.
