How to prep and seal new pour driveway?

[okaku]

Hi everyone, I had my aggregate driveway poured about 2 weeks ago. and now I am seeing patchy white marks or spots that won't go away even with scrubbing.

I forgot to include the seal on the quote and now I am hopping to learn how to do it my self.

From my research the white marks might be efflorescence, but I am not sure which product to use to clean and seal afterwards.

So I am hopping to get some guidance on the products and proper step to follow?

Thank you!

Welcome to the Bunnings Workshop community @okaku. It's wonderful to have you join us, and many thanks for your question about driveway sealing.

I'm sorry, but could you please clarify what type of driveway you have? I am guessing it might be an exposed-aggregate concrete driveway or perhaps a Pebblecrete driveway. If we can confirm what it actually is, we can point you toward the right cleaning products and the correct type of sealer. If you can share a couple of photos of the white marks you are seeing, that will help confirm whether it is efflorescence or something else. Let me know if you need a hand uploading images. 

It is also worth contacting the contractor who installed the driveway, because they might be able to advise on the appropriate sealing process for that specific finish. Once we know the material, we can guide you through the right steps to clean and seal it properly.

Please let me know if you have any questions.

Hi @okaku 

I suspect most likely from either a poor mix from the supplier or it hasn’t been acid washed evenly. The later was the issue causing my similar issue some years back. 

I would contact the concreter to assess being just poured.

Hello, Thank you for your reply.

It is an exposed aggerate concrete driveway.

Unfortunately the contractor is fully booked at the moment, and I was just wondering if I could do the acid wash and sealing by myself.

Thank you
