Trowel finish on Self-compacting concrete
Trowel finish on Self-compacting concrete
(OP)
When I tried to do steel trowel finish on precast walls, self-compact concrete was stuck to the trowel like glue.
And the finish is not looking good.
Someone says sprinkling water will help, but this may cause durability issue like scaling.
Is it acceptable practice to sprinkle water before troweling on self-compacting concrete slab?
Please tell me how to finish self-compacting concrete with steel trowel.
Thanks for your time!

Thank you very much for your info!
Can you tell me when I should try a magnesium float first and then how long I should wait to use a steel trowel?
Do you think these timings are VERY different among concrete mix designs?
I wonder how you can decide WHEN to start troweling.
Thanks again!

Keep in mind, I'm an engineer and not a concrete finisher. I definitely am no expert at running a trowel compared to the guys in the shop.
