Fields of application

weber.plan 819 is used as a non-sag and shrinkage-compensated mortar for levelling and repairing walls and floor surfaces of different substrates. Following substrates are allowed: concrete (sufficiently old, professionally treated, in swimming pool constructions at least 6 months old), masonry with compressive strength ˃ 6 N/mm² (e.g. sandlime brickwork, concrete block), lime-cement and cement renders with compressive strength ˃ 6 N/mm² (class CS IV), cement and quick-cement screeds. Also, as full-surface render, also in swimming pool constructions. For indoors and outdoors.

Main features

• compressive strength of class CS IV (EN 998-1)
• non-sag
• does not stick to the tools
• for walls and floors
• for substrate levelling and as gradient layer
• for swimming pools

General notes

• Do not process already stiffened material.
• All characteristics mentioned in this data sheet are based on a temperature of +23 °C without draught and a relative humidity rate of 50%.
• Higher temperatures and lower humidity accelerate, whilst lower temperatures and higher humidity delay the setting process.
• The freshly applied mortar must be protected from draughts, strong sunlight or heat.

Special notes

• Limits of use: do not use on cellular concrete, lightweight masonry and substrates containing gypsum or anhydrite.
• Swimming pools must consist of watertight concrete, or after being levelled with weber.plan 819, must receive a waterproofing system, for ex. weber.tec 824, weber.tec Superflex D 2, weber.tec 827/827 S or weber.xerm 844 (bonded systems). The waterproofing works can begin after around 24 hours.
