Main properties

    improved resistance to efflorescence does not stain the surface of bricks for grouting walls made of clinker brick based on filtrated aggregate

Main parameters

    Bulk density (of dry mix): approx. 1.6 kg/dm³ Mixing ratio – bricklaying (water/dry mix): 2.5 ÷3.0 l / 25 kg Mixing ratio – grouting (advised water volume) (water/dry mix): approx. 2.0 l / 25 kg Min./max. mortar thickness 6 mm / 40 mm

NEW COLOUR RANGE

Go top
Manufactured in 5 new colours - matching typical colour range of clinker: anthracite-black, grey, beige, graphite and dark brown.

PROPERTIES

Go top
Resistant to salt efflorescence – manufactured on the basis of high quality pure Portland cement with addition of trass (a mineral of volcanic origin). Low content of mix water, addition of trass and specially selected admixture-free binder ensure protection from efflorescence occurrence.
Filtered aggregate – quartz aggregate used for the mortar production is subject to the process of sifting and flushing. Thus, the grains are free from pollution, soluble salts and other minerals causing the effect of salinity.
Resistant to UV radiation – properly selected chemical composition of powder pigments used in the mortar recipe (iron oxide) makes the mortar resistant to UV radiation. Therefore, intensive colours do not fade and the mortar keeps its strength parameters in operation.
Very good workability – properly selected aggregate composition (up to 1.2 mm) makes the mortar easily applied and shaped. Enables large scale bricklaying free of the phenomenon of mortar pressing out from the bottom layers.
Does not stain the surface of bricks – content of specially selected inorganic pigments and low concentration of mix water makes the surface of bricks easy to clean dry or with a soft brush – in consequence a wall is free from stains.
Compressive strength – category M5.
High bonding to elements of low absorbability.
Vapour-permeable and hydrophobic.

BRICKLAYING

Go top
Preparation of masonry elements
Clinker elements must be clean, free from dust and dry. Protect against rain and excessive heating when stored. Due to the possibility of occurrence of slight differences in a colour shade between bricks from various production batches, it is recommended to mix bricks coming from several pallets before the application commencement.
 
Weather conditions
Consider weather conditions during bricklaying as well as during mortar setting and drying. All works have to be carried out at temperature between +5°C and +30°C. During work and afterwards (within min. 7 days), cover the masonry elements with foil or mats protecting from precipitation and excessively quick drying caused by wind and sun action. Do not carry out application in precipitation. It is also advisable not to commence work if the weather forecast anticipates rain or temperature drop in the following days. Moreover, the masonry structure and its foundations must be appropriately proofed against uncontrolled damp, e.g. capillary action from the substrate.
 
Mortar preparation for bricklaying or grouting
Pour the mortar from the bag into a clean container with the suitable amount of water (see Technical Data for ratio – note the difference in ratio for bricklaying and grouting) and mix using a mixer with a drill (or a cement mixer) until homogenous. The mortar is ready to use directly after mixing and should be used up within approx. 3 hours.
 
One stage bricklaying
Lay bricks with full joints, as it limits the possibility of rainwater penetration into the partition. Joint thickness should be even for the whole layer. Prepare an appropriate tool with rounded section made of plastic or wood for the grout shaping. The time of commencement of joint shaping depends on weather conditions, brick absorptivity and resultant mortar setting. It should be carried out a dozen or several dozen minutes since the mortar application when, if touched, the fresh mortar does not soil fingers. Note. The level of mortar setting during grouting needs to be the same for the whole surface.
 
Two stage brickwork
To form even joints and keep the level of successive layers, one can use appropriately prepared wooden beads or other limiters (recommended thickness: 10÷12 mm), arranged on the set bricks layer along its edge. The first stage – bricklaying – consists in joining bricks with the masonry mortar and leaving space for the grout (masonry mortar fills the space between the beads only). Grouting the wall with ATLAS MASONRY MORTAR FOR CLINKER should start not earlier than 7 days since the first stage.

IMPORTANT ADDITIONAL INFORMATION

Go top
·       Use mortar of the same production batch and always use the same amount of mix water for each individual section.
·       Pay special attention to cleanliness of successive elements being laid. If mortar contacts the face of a brick, remove it as soon as possible (most preferably with a dry method).
·       Noncompliance with recommendations and requirements concerning the mortar preparation, application and maintenance may result in salt and lime efflorescence. Efflorescence is a natural phenomenon occurring with cement mortars and is not directly related to the application of ATLAS MASONRY MORTAR FOR CLINKER. Salts causing efflorescence may come from other mortars, substrate or clinker elements themselves.
·       Tools must be cleaned with clean water directly after use. Difficult to remove residues of the set mortar can be removed with the ATLAS AGENT FOR REMOVAL OF CEMENT DEPOSITS AND STAINS.
·       Contains cement. May cause respiratory irritation. Causes skin irritation. Causes serious eye damage. May cause an allergic skin reaction. Keep out of reach of children. Avoid breathing dust. Wear protective gloves/protective clothing/eye protection/face protection. IF ON SKIN (or hair): Remove/Take off immediately all contaminated clothing. Rinse skin with water/shower. If skin irritation or a rash occurs: Get medical advice/attention. IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do – continue rinsing. Follow the instructions of the Safety Data Sheet.
·       The mortar must be transported and stored in tightly sealed original and labelled bags, in dry conditions (most preferably on pallets), do not expose to the direct sunlight. Keep in dry, cool and well ventilated room, away from incompatible materials (see Safety Data Sheet – section 10), food and beverages. Protect against humidity – product gets irreversibly solid. Shelf life in conditions as specified is 12 months from the production date shown on the packaging. Content of soluble chromium (VI) in ready-to-use mix - ≤ 0.0002%
