The temperature of the substrate and air during the works should be from +8°C to +30°C.
Works should not be carried out during precipitation and strong sunlight.
Suitable substrates are: concrete, screeds, cement and cement-lime plasters, gypsum plaster boards, well jointed masonry, OSB. 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. OSB should be sanded, dedusted and should not be moistened before applying the material.
Check the production date on the packaging before use. The product should not be incorporated beyond its shelf life. The product should not be objectionable (e.g. contain lumps, discolouration, fibres) after opening. The powder component should not be damp or clumped. After mixing, the compound should be homogeneous and free of lumps and clumps resulting from under-mixing. Do not use a product that bears signs of freezing. When properly mixed, the product forms a homogeneous coating when spread over the surface with a tool.
AQUAMINERAL 2K Ultra is supplied in two separate packages. Pour the powder component into the liquid component and stir for at least 2 minutes until a homogeneous mass without lumps is obtained. After the maturing time of 5 minutes, mix the material again.
If partial use is assumed, the product should be prepared maintaining the weight ratio of the components (3 part component A and 5 of component B).
Depending on the prevailing atmospheric conditions and the absorbency of the substrate, water in an amount of up to 3% of product weight can be added. The addition of water allows to obtain the right consistency related to the type of application. The mixed, ready-to-use material 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 2K 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 successive layers), maintain a technological break of at least of 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.
After a minimum of 12 hours from applying the last layer, ceramic cladding can be bonded to the dried compound using mineral adhesives.
Before use, please read the application details in the product's Technical Data Sheet.

approx. 1,5 kg/m² - per layer 1 mm
approx. 3,0 kg/m² - damp-proof insulation, thickness of a bound coating 2 mm
approx. 3,75 kg/m² - waterproof insulation (water not exerting pressure), thickness of a bound coating 2,5 mm
approx. 4,5 kg/m² - waterproof insulation (pressurised water), thickness of a bound coating 3 mm
