AVAL KT 28 MASONRY MORTAR is designed for traditional masonry work such as walls made of bricks, hollow bricks and other similar ceramic, concrete or lime-sand materials. It is suitable for masonry work of above-ground storeys as well as cellar walls and foundations. Joint thickness made of the masonry mortar should be 6 to 40 mm. It is suitable for internal and external use.
Use in reduced temperatures
So-called antifreeze agents that enable work in reduced temperatures i.e. below +5°C can be added to the mortar. The new temperature range of mortar utilisation, method of preparation (in particular adjustment of the amount of added water), principles of conducted work and setting conditions have to be assumed in accordance with instructions of additives’ manufacturer. The amount of antifreeze agent added depends on the cement content in the mortar – the ratio of cement to fillers in AVAL KT 28 MASONRY MORTAR is 1:3. Note: Mortar manufacturer is not responsible for effects and quality of applied antifreeze additives. |

|
| In order to prepare the mortar, pour dry mortar into a container with suitable amount of water (in proportion: 3.6÷4.2 l water for 30 kg of dry mixture) and mix until homogenous. Use a concrete mixer or a drill with a mixer. The mortar is ready to use immediately after mixing. It maintains its properties for ca. 4 hours. |

|
| The method of application should be in accordance with the masonry work technology using cement mortars. In particular, take into account weather and the type of material which elements are made of. They should be clean and free from dust. Apply the mortar with a trowel evenly on a horizontal plane of the previously prepared layer. Horizontal and vertical joints should be completely filled in with the mortar (unless other method is anticipated by a given method). Leave an empty joint (5÷10 mm deep) at external fronts near walls to be plastered. Joint thickness should be even for the whole layer and should be from 6 to 40 mm. The mortar can be used in substrate and ambient temperature from +5°C to +30°C. The information comprises basic instructions of product application and does not relieve users of responsibility for work in accordance with good construction practice and OHS regulations. |
