Screeding Of Floors.pdf

This work instruction is for planning and preparation of screeding floors on construction projects, aiming for high personal safety, efficient work, and cost-effectiveness. It covers pre-conditions, self-inspection, and subfloors, specifically screeding of concrete floors with a pump. The instruction explains binders, fillers, and additives in screeding materials, such as aluminous cement, natural sand, and polymers, and notes the lower pH value of floor screed materials compared to concrete. It also discusses normal and self-dehydration of screed, allowing for early laying in a project. A risk assessment is provided, evaluating probability and consequences of accidents, such as slips, trips, and eye injuries, and recommends actions like checking surface level differences and wearing protective gear. The instruction also covers safety regulations, personal protective equipment, and preparation steps, including checking the surface and logistics, such as transporting screeding compound and handling underfloor heating.
