comment Types of floats and trowels for concrete
Excelent answer, just one question. Why spread skim coat/plaster using steel trowels? From what I understand, steel should be used as a last step, right?

comment How thick should a plate steel stringer be?
I found the following document about flat stringers, they explain what you just told me. I think that I probably could work with 2 flat stringers, but I would then use 1/4" stock. But stiffness is important, I think that without an U profile I could have too much vibration when walking up the stairs. steelconstruction.org/…

comment How thick should a plate steel stringer be?
Thanks for the tips, one final doubt, do you think it is doable to have both stringers be made from flat plate, without "wings" like an U profile for reinforcement. After your encoragement I'm thinking on going for a more clean design, maybe using a thicker plate just for the looks.

So, considering that the other stringer will be a U profile about 8x2" 1/8" thick, what you recommend for the flat stock one: 1/8, 3/16?

No, the "floating" one will be a U profile 20x5 cm 3mm thick.

comment Seamless construction joints on concrete floor
I knew those recommendations, but I don't think it touches on the point of my post. It makes no mention on how the batch should end to form a proper joint (it just says it should be laitance free, which is a given) and althought it mentions that constructions joints could be used as control joints (what I intend to do), it unfortunetely doesn't offer any advices on how it is done.

comment Rotary hammers, how many joules to hammer through concrete slab?
I'm aware of the core drills. Their cost is the reason I decided to go the rotary hammer way. Just 2 sizes (80 and 110 mm) of those for using with a regular drill costs more than a 2.4 J rotary hammer.
