SANAKOLL is a low specific weight, low modulus of elasticity and highly breathable adhesive-skim coat. Its thermal conductivity value, < 0.2 W/mk, allows SANAKOLL to be classified in the family of thermal mortars in category T2, according to UNI EN 998/1. Its high breathability, combined with very low capillary absorption values, allows the transmission of water vapor and at the same time, thanks to special additives contained in the formula, counteracts the passage of liquid water. Its high adhesion on different types of substrates makes it the ideal skim coat/adhesive for the SANATEX membrane. The SANAKOLL-SANATEX system is used on thermal bridges, damp masonry, damaged supports, precisely by virtue of the physical-mechanical performance of the system. The smoothness of the product and its low specific weight, obtained with correct mixing with water, allows smooth, easy and fast application. SANAKOLL is a very versatile product that is also excellent for smoothing, leveling and gluing light cork elements or wood-magnesite panels.
Fine-grain smoothing of lime or lime-cement based plasters and mortars. Regularization of plastered masonry up to a thickness of 5 mm applied in a single coat. Smoothing of concrete walls. Smoothing of stone elements, bricks, hollow blocks and other brick products. Adhesive-skim coat for the installation of the special SANATEX membrane, used in cold masonry (thermal bridges), in order to raise the dew point temperature of the surfaces, and in damp masonry, affected by capillary rising damp. Bonding of wood-magnesite panels, cork panels and other types of ecological modular panels, in the construction of "natural coats" (internal and external). Bonding of small-sized, medium-absorbent, non-clinkered, porous tiles and tiles on both internal and external floors and walls.
The application supports must be free from dirt, dust, loose parts, etc.; pre-existing paints (washable, organic, solvent-based, etc.) must be removed. It is always advisable to operate on the application support with suitable mechanical methods capable of slightly roughening the surface, up to degrees from 3 to 5 of the ICRI methodology. Wash the surfaces with pressurized water to completely remove the dust and moisten the dry substrates immediately before applying SANAKOLL.
Gradually pour about 2/3 of the mixing water into the mixer. Gradually add Sanakoll and the remaining water, continuing to mix until all lumps have been eliminated. The total percentage of mixing water is between 28% and 30% (from 7 to 7.5 liters for each 25 kg bag).
The methods of use differ according to the specific intended use.
For bonding on ordinary, absorbent substrates, indoors and outdoors, spread the product with a notched trowel in continuous layers, of suitable thickness, and then apply the elements to be installed (SANATEX membrane, panels, etc.), in the manner appropriate and usual, exerting the necessary pressure to promote adherence.
For smoothing smoothing it is always advisable to apply two coats, waiting at least 8 hours and no more than 48 hours between the first and second coat. In particularly arid or windy climates, slightly wet the surfaces between the first and second coat. Finish the surfaces with a blade or a trowel according to the desired effect. In arid, windy or very hot conditions, it is advisable to moisten the surface of the Sanakoll applied for the first 48 hours with light and repeated nebulisations of water.
Respect the minimum and maximum application temperatures. In summer, apply Sanakoll on shady supports, avoiding the hottest hours of the day. Do not apply when temperatures > 30° C are expected in the first 12 hours of maturation. In winter, do not apply the product when temperatures below 5° are expected in the first 12 hours of maturation. Do not apply when temperatures below 0°C are expected in the first 24 hours of curing.
