Grouting a Joint Between 90 d Surfaces

[carlyai]

I need to grout a joint between a tiled area and a garage wall, as per the pictures.

Sprinkler water is leaking through the joint into the garage.

I have some Crocodile brand flexible waterproof grout.

I was wondering if there is a 90 degree tile grouting tool for applying the grout.

How would you do it?

While waiting for replies I posed the question on You Tube and a tiler used Profiling Kit 5, which seems what I need.

Found similar on Lazada.

All good.
