To seal brick paving, I suggest using Crommelin Natural Finish Penetrating Sealer And Water Repellent.
It is a natural finish penetrating sealer providing long-term water and mould repellence. It also allows natural substrate breathability and will not increase the slipperiness of your brick pavers.
If you also need to rejuvenate between the bricks, what you use depends on the size of the gaps.
Usually I would suggest using Dingo 20kg Powerloc Paving Sand.
But if the gaps between your bricks are big, I recommend using a traditional mix of sand and cement to fill between your bricks. - EricL
