AQUAMINERAL 1K Ultra

Suitable substrates are: concrete, screeds, cement and cement-lime plasters, gypsum plaster boards, well jointed masonry. Do not apply to concrete sealed with crystallising mortars.
The substrate intended for product application must be clean, load-bearing, even, porous and seasoned. The substrate must not be frozen, frosty, stagnant water must not occur. The substrate should be cleaned mechanically, dust, any loose layers, sharp protruding edges and impurities that worsen adhesion should be removed. If there are cavities, honeycombing, gravel pockets and other unevenness in the substrate, it should be repaired, filled with suitable mortars from the NEXLER RENOBUD R series.
Special attention should be paid to the preparation of the substrate at the joints of elements (corners, joints of vertical and horizontal surfaces). Embed a sealing tape in all corners, e.g. NEXLER Sealing Tape 120/120, or make a facet (rounding) with a radius of approx. 5 cm using NEXLER RENOBUD R 103 mineral mortar.
Immediately prior to application, the prepared mineral substrate should be slightly moistened, avoiding water stagnation. Substrates with a regular absorbency, dust-free do not require priming. Highly absorbent substrates and those containing gypsum require priming with NEXLER Gruntofol.

Check the production date on the packaging before use. The product should not be incorporated beyond its shelf life. Once opened, the product should not raise any concerns (e.g., contain lumps, clumps or mechanical impurities). After opening the package, the mortar should be dry, with no visible signs of moisture. Do not use the product if it shows signs of freezing. After mixing with water, the mortar should be homogeneous, free of lumps and clumps resulting from insufficient mixing. A properly mixed product spreads easily over the surface and does not run off it.

Pour the content of the bag into a clean container and mix with pure water until a homogenous consistency is obtained that is appropriate to be used with tools. Mix the material with water in a 1 to 0,22 - 0,28 l weight ratio (3,3 - 4,2 l of water per a 15 kg bag). The mixture prepared as described above should be used within 1 hour. The matured material cannot be stirred and processed again.

Thickness of a layer should be checked by material consumption control on a dedicated surface. In addition, it is recommended to measure the thickness of the freshly applied sealing layer with special inspection plates, the measurement point should be filled with putty immediately.
After it has dried, a properly made coating should be a uniform, clean coating, without flakes and other defects. The coating should adhere closely to the substrate.
Particular attention should be paid to corners and areas where plumbing and other components pass through partitions - these need to be assessed for proper embedding of tapes, corners and cuffs.
The occurrence of colour variations or possible discolouration on the surface of the coating is related to the varying humidity of the air and substrate and to the varying thickness of the coating. This does not indicate a defect in the product and does not affect the quality of the applied layer.

AQUAMINERAL 1K Ultra can be applied with a brush, trowel or spray equipment.
In order to close the pores in the substrate, it is necessary to rub in a first, thin layer with a brush. Before applying each successive layer (between applying following layers), maintain a technological break of at least 3 - 4 hours for the layer to dry. The recommended application thickness per layer is 1 mm (no thicker than 2 mm).
During setting, the coating should be protected from precipitation, frost, overly rapid evaporation of water and large temperature differences for approx. 12 hours. 

Before use, please read the application details in the product's Technical Data Sheet.
