Hi @xircomnz,

I suggest using Dulux Avista 10L Exposed Aggregate Concrete Sealer for your project. Here are the directions for its use. 

For cleaning the surface, I recommend using 30 Seconds 5L Outdoor Cleaner Concentrate in combination with a pressure washer. Once the area is clean you'll need to acid etch it with hydrochloric acid as per the products instructions.

Remember your PPE, including a face mask, eye goggles, acid-resistant gloves, a long-sleeved shirt, trousers and enclosed footwear.

Please let me know if you have any questions.
