Seal between aluminum and stone (outdoors)

[TBH]

I have just assembled a greenhouse with an aluminum frame.
I have placed it on a prepared stone-paved ground slab (granite stone).
It stands very straight and level on the slabs.

To further prevent ants and water from coming in from outside, I am considering sealing between the aluminum base and the stone slabs, like silicone, stone glue or something similar.

Do you think this is a good or bad idea?
What should I use to seal it to withstand weather, temperature, and UV?
Seal from inside the greenhouse or from the outside (or both sides)?

Grateful for all responses.

Hey,
I would probably go with polyurethane foam (all-year-round) on the outside. I think it's fine to paint over it.

P.S
You have it a bit reversed.
Plants and soil outside and outdoor furniture inside.

combined, half has a seating area for a glass of wine before dinner and the other half is (or will be) full of pots and boxes, as well as a shelf with odlingar.

I had sealed with soft sealant both inside and outside nicely stable and lasts long.

I prefer not to have a large foam seal but envision a thin seal between the stone and the base, preferably black and on both the inside and outside.

Here's what it says about stone adhesive PU700:
1-component moisture-curing foam adhesive based on polyurethane, for horizontal bonding of stone materials.
- Resistant to fresh, salt, and lime water, withstands weak acids and corrosive mixtures
- Also bonds wood/wood, wood/concrete, and metal and aluminum to absorbent surfaces

What does PU700 look like? Large ugly foam or like a string of adhesive?

Here you have a good product. And as a primer on the tiles, it's Bostik 5075 that applies to this
