Try to maintain a comfortable position while working. Hand troweling can be very stressful on your the back, hands and arms. If you are physically able to do so, stretching before work and taking mini breaks (a few seconds) can help relieve stress and fatigue. Try not to over reach, as this can be place additional stress on your back and wrists. Maintaining downward pressure on the hand trowel can cause injuries to the hand or arm. Hand trowels can be modified to reduce pressure on the palm.
Cement can cause irritant/allergic contact dermatitis, alkaline burns, dry skin or irritation. Use proper gloves, wash and dry hands when necessary. Do not bring cement dust home; remove work clothes before leaving the work site. Work clothes should be laundered separately.
