What is trowel burn?
Trowel burns are caused by hard-troweling a surface so stiff that the trowel angle can be very high without causing chatter marks. Tilting the trowel increases pressure on the trowel edge and this densifies concrete at the surface.
What is the best thing to put on a concrete burn?
First aid treatments for concrete burns include: - Remove wet clothing and shoes.

Smoother (polished) concrete surfaces can be achieved through extended honing using progressively finer abrasives (finer grinding grit heads/pads) to impart a lustre to the concrete surface.How long does concrete burn last?
Postburn sequelae include scar hypertrophy, skin fragility, and pruritis. These occur more frequently when healing is delayed for more than 3 weeks, as full-thickness burns, which are common in cement burns, do not heal by secondary intention.Can eating cement kill you?
