SA813 is a dry mix of cement, sand and additives to which only water is added in order to obtain a ready-for-use adhesive mortar for cellular concrete and other light-weight building elements. SA813 has a very good resistant strength and a long open time. Workability is excellent
Directions for use
Mix thoroughly 40 kg of SA813 with ± 10 litres of clean water. Let the SA813 settle for 10 to 15 minutes before mixing it thoroughly once more
Mixing ratio Consumption Packaging ± 10 l water per bag of 40 kg Depending on the width of the stone 40 kg Colours Processing time Application temperature White ± 3h + 5°C till + 35°C .
- Weatherproof, and resistant to frost after hardening
- Strong friction bond due to the adjustment of the water retention properties to suit the absorbency characteristics
of the aerated concrete
- NO rapid loss of water, or loss of water to the subsurface
- Easy correction of brick position after the brick has been laid
- Good workability
- Fulfills the mortar requirements for subsequent thin plastering
♥ Add the 40kg of dry mortar contained in the sack to approximately 10 litres water and mix, either by hand or using a mixer, to a smooth workable paste. The correct consistency has been achieved if the mortar stands in a stable ridges when scored with a notched trowel. After allowing the adhesive to rest for approximately 5 minutes, mix the mortar again briefly. Apply the mortar without adding any further ingredients.
♥The first layer of high precision units must be laid horizontally and flush in the mortar bed. Before laying and bonding the second layer of units, level off any uneven areas. Clean any dust from the surfaces of the units.the adhesive should be applied for no more than 2 or 3 high precision unit lengths at a time. Apply by hand or using a mortar sledge to comb the mortar into place in a layer approximately 1 to 3 mm thick. Put the high precision units into place from above, wherever possible, and tap into position using a rubber hammer. Avoid pushing the units along longitudinally.
♥ The fresh masonry work must be protected from unfavourable weather conditions such as very high and very low temperatures, frost, draughts, direct sunlight and driving rain (by covering with a plastic sheet, for example). Do not carry out works at air and masonry temperature below +5°C.
