How to repaint old painted pebblecrete driveway?

[kathy7]

Hi everyone  we bought a house and the previous  owners have painted  the driveway  but the paint is peeling  off however  there are three layers  of different coloured paint the first being easy to remove with the hose the second a little more stubborn  and the third  more stubborn. I'm looking  for the most cost effective  way to make thus drive look at least decent  so any suggestions  would be appreciated. Thanks

Hi @kathy7,

Thank you for your question and welcome to the Bunnings Workshop community, it is fantastic to have you with us.

The easiest way to give your driveway a refresh is to paint over what is already there. The problem with this is that your new layer of paint is adhered to the layer beneath, so it will only be as good as the coat of paint that it is adhered to.

You've indicated that the top layer of paint hasn't adhered well to the layers beneath, but the layers beneath are better adhered.

My suggestion would be to use a high-powered pressure cleaner such as this Full Boar 3200PSI 7HP Petrol Pressure Washer to go over the driveway and remove as much of the poorly adhered paint as possible.

Once the poorly adhered paint has been removed, you can use a concrete primer designed for use over existing coatings. This Rust-Oleum 3.78L Concrete and Garage Recoat Primer is a good option.

Now the surface has been primed, you can use a concrete paint in a colour and finish of your choosing to recoat the surface. Ensure you follow the manufacturer's instructions closely to ensure you get the best result possible.

Let me know if you have any further questions.

We have had a man come out and jetblast most  of the old paint off however  there are spots that the yellow  under didn't come off, could I use a tinted  sealer  over the surface?

Hi @kathy7,

Do you have an updated photo you could share?

I can't say I'm aware of a tintable concrete sealer that can be used in this application. 

There are clear sealers like this Dulux Avista Exposed Aggregate Concrete Sealer which can be used on exposed aggregate concrete, but they can't be applied over painted surfaces, so you would need to be sure that all of the paint is removed.

Unfortunately, painting over the old, well-adhered paint, is still likely your best option.

Let me know what you think.

Hi @kathy7,

The pressure washing has certainly done a great job of removing the old paint. I think it looks pretty good how it is now, but I understand wanting to cover up the old paint.

From here I see two main options, paint or a sealer.

As I mentioned before, I'm not aware of a tintable sealer that is usable in this application as all concrete sealers I can find say they can't be used over old paint.

If you wanted to use a sealer, you would need to have the concrete ground back to remove all the paint before a sealer can be applied.

As the poorly adhered paint is now gone, painting over the concrete is likely the best option.

Let me know what you think.
