We have these 2 paver steps that are awkwardly tall. I'd like to add 2 steps to this by adding another layer of pavers to the lower step here, then adding 2 steps going off of that.

Would it be a bad idea to just lay the new steps directly on the existing ground level patio steps?

I've seen mixed guidance on using construction adhesive vs just polysand. Any thoughts on that?

    Polymeric sand wouldn't be a good fit for this use case, you’ll need to use a mortar or something like loctite pl500 to avoid creating a potential trip hazard. Polysand does bind, but not strongly enough for this, it’s more or less just to keep pavers from shifting and plants growing between them.

    You should be fine laying new steps on the existing provided they’re in good shape. (Relatively level, no cracks)

    I would probably at least pull that bottom layer of decorative pavers out and lay new corner pavers there to provide a better base for the steps.

      Cool, these do seem like they're in decent shape so tearing that out seems like a shame.

      Certainly couldn't hurt. Seems like the other steps may just be on a bed of cinderblocks, can't quite tell though. Should probably try to match that while tearing the other pavers out.

      Do you think these steps were bound with something like pl500? Doesn't look like mortar to me

        Hard to tell from a photo, but it looks like it to me. I’ve mostly seen landscaping adhesive used for securing cement paver steps, it joins very strongly, it’s quicker to set than mortar, and it’s a hell of a lot easier to work with than mortar.

        You’ll probably have an easier time of it ultimately if you pull out those decorative pavers where you intend to lay the new steps and replace them with some wider step or corner pavers. Much sturdier base and you’ll get a better adhesive bond.
