Application
Masonry mortar is intended for masoning of external and internal walls with a traditional thick joint, joining aerated concrete blocks, aerated concrete, expanded clay concrete, hollow blocks, ceramic materials, lime-sand elements and other similar materials. It is used in small and multi-purpose construction, both for newly constructed buildings and those renovated. This mortar replaces traditional building mortars, which are mixed at the construction site by faster and easier preparation and the possibility of mixing smaller batches of mortar. It also allows you to correct dimensional inaccuracies of wall elements. It has good adhesion to the ground and high durability.
Properties
Masonry mortar is a ready, dry mix of the highest quality, based on gray cement class 52.5 R, cleaned sand, aggregates and modifying additives. It is characterized by good workability, plasticity and adhesion to various types of building materials, which makes it a product with a very versatile application and easy to process. With very high adhesion to the ground. Masonry mortar is a frost-resistant and waterproof product. It is also characterized by high tightness. Due to its properties, it prevents thermal bridges in single and multi-layer walls. It also affects the faster pace of construction works.
Substrate preparation
The substrate should be dry, matured, stable, even and sound, i.e. strong enough, cleaned of layers that can weaken mortar adhesion (dust, dirt, lime, oils, fats, wax, residual oil and emulsion paint). If it is necessary to make a layer of mortar on solid substrates with a load capacity difficult to determine (e.g. dusty, difficult to clean), it is recommended to carry out an adhesion test consisting of applying a control layer and checking the connection after a minimum of 48 hours. Loose items must be removed. Blocks, bricks and highly absorbable elements should be wetted with water before laying in hot weather. It is recommended to use elements of the same variety with the same strength class on one floor and the same type of mortar when dealing with load-bearing walls.
Mortar preparation
Preparation involves pouring dry mortar into a container with the right amount of water (3.5 - 4 l per 25 kg). Then mix the mass manually or mechanically using a low-speed drill with a mixer or concrete mixer until a homogeneous mass without lumps is obtained. Leave for about 5-10 minutes and mix again. If necessary, add a small amount of water and mix again to obtain a proper consistency. The mass prepared in this way should be used within 1 to 2.5 hours depending on weather conditions. It is unacceptable to modify the mortar by adding other components of construction chemicals, e.g. sand, cement, and other additives, as it may cause loss of mortar properties.
Application method
Masonry mortar is applied after preparing the substrate. It is unacceptable to apply too thick layer exceeding the standard values in construction once. After applying the mortar, proceed to the initial laying of the material by pressing and then collecting excess mortar using a trowel. Bricklay with full joints. When the mortar dries inside the room, good ventilation must be provided. When working outdoors, protect the applied layer from direct sunlight (drying too quickly can lead to cracking of the mortar), as well as protect the surface from direct rain. The air and substrate temperature during works as well as in the process of setting and drying must be positive (above + 5 ° C, but not higher than 25 ° C). Assuming that the resulting wall will be intended for plastering, leave an unfilled joint 5-10 mm deep at the outer faces. In addition to the recommendations provided, work should be carried out in accordance with building practice and health and safety rules. The manufacturer guarantees the quality of the product, but has no effect on the conditions and the way it is used. In case of doubt, carry out adhesion tests or contact the manufacturer. Fresh dirt after mortar should be washed with clean water, while hardened should be removed mechanically. Work in temperatures between + 5 ° C and + 25 ° C. For a period of 7 days after the completion of works, the air temperature should not be below +5 ° C, and for the next 21 days should not fall below 0 ° C.
Expenditure
On average, consumes from 34 kg / 1 m² of a wall with a thickness of 1/2 full brick with a joint thickness of 10 mm. In practice, the wear depends on the degree of thickness of the weld, as well as the dimensional accuracy of the joined elements. Mixing ratio 3.5 - 4 l / 25 kg.
Storage and transport
The products must be absolutely stored in undamaged packaging and dry rooms on pallets. Protect from moisture, getting wet during storage and transport. The storage period of the product in conditions complying with the recommendations given is up to 12 months from the date of production placed on the packaging in digital print. The production date, which is placed on the packaging, is also the date of manufacture of the product. Any changes visible in the product or packaging structure without special tests, in particular discoloration or smudging of the packaging graphics, infringements of the packaging continuity, biological changes in the product structure, recognizable in particular as a consequence of moisture, may indicate poor storage or transport conditions and do not guarantee compliance declared performance characteristics of products as specified.
Packaging
25 kg paper bags. Pallet: 54 bags, 25 kg each, 1350 kg overall per pallet.
Precautions
The product contains cement which, when mixed with water, gives an alkaline reaction. Take measures to prevent dusting or splashing with the mortar. Do not inhale, protect eyes and skin. In case of contamination: rinse eyes immediately with plenty of clean water and seek medical advice, wash skin with soap and water. Keep out of children's reach. If swallowed, seek medical advice immediately and show the container or label.
Temperature of performed work
Air temperature from + 5ºC to + 25ºC. Substrate temperature from + 5ºC to + 25ºC. Working time of 1-2.5 hours at specific temperatures and humidity. M5 strength class.
