Use <br /> opened packaging promptly.</p> <p>Art.-No. 2 01411</p> <p>Substrate preparation: <br />The substrate must be load bearing and free from <br />adhesion inhibiting media such as release agents, dust <br />or other coatings. Remove old render/plaster, paint and <br />laitance up to 80 cm away from the damaged area <br />determined visibly or by analysis. <br />Rake out brittle masonry joints to a depth of 2 cm <br />and clean mechanically. Concrete surfaces must <br />be open-pored. Where the salt content is high, pretreat with ESCO-FLUAT. Apply a splatterdash coat of <br />THERMOPAL-SP as a bonding coat (degree of <br />coverage approx. 50%). <br />As an alternative to THERMOPAL-SP, the splatterdash <br />coat can be produced as follows: <br />Emulsion comprising ASOPLAST-MZ : Water, mixed 1:1 <br />to 1:3. Dry blend comprising cement and washed sand <br />– grain size 0.4 mm - mixed at a ratio 1:2 by volume. <br />Produce a workable consistency from the emulsion and <br />dry blend and use within approx. 1.5 hours. <br />Product preparation: <br />THERMOPAL-SR24 can be prepared in all usual <br />continuous mixing pumps (e.g. with the High-Pump Basic <br />from HTG-HIGH TECH Germany GmbH, Berlin or PFTG4). If, due to machinery equipment, an air entrainment <br />of 20-30% is achieved then there is no need for a <br />secondary mixer. Small quantities can be mixed by <br />hand with a drill mixer. <br />Machinery PFT-G4: <br />Pipe length: <br />Pipe size: <br />Stator / rotor: <br />Spray head for <br />scratch coat: <br />Water addition: </p> <p>max. 20 m <br />25 – 35 mm <br />D4-2 LP <br />Nozzle size > 17 mm <br />approx. 300 – 325 l/h</p> <p>THERMOPAL-SR24 can be applied with appropriate <br />tools such as plasterer‘s float, steel float or similar at <br />thicknesses in accordance with WTA guidelines as well <br />as in single layers up to 3 cm in one operation. After <br />an adequate waiting time the surface can be rubbed <br />off or finished with a felt board. Rubbing off too early <br />produces a binder concentration at the surface and may <br />cause stress cracks.</p> <p>1/2</p> <p>34/16</p> <p>As an alternative the surface can be worked with a grid <br />float. This operation can be carried out after 8 – 24 <br />hours dependent on the ambient conditions. Rubbing <br />with the grid float removes the laitance layer which <br />appears and results in a considerably greater diffusion <br />performance. Dependent on the ambient conditions the <br />surface can be smoothened with THERMOPAL-FS33. <br />For thicker coats, apply in several layers. In these cases <br />strike off the previous coat with a plasterer’s darby and <br />immediately the mortar stiffens, roughen up horizontally <br />and allow to dry. <br />Keep to a waiting time of 1 mm per day.</p> <p>• P rotect from strong sunlight. <br />• Smooth surfaces can be achieved by trowelling with <br />THERMOPAL-FS33. <br />• For coloured finishes use highly vapour permeable <br />silicate paint. <br />• Observe the WTA information sheet “Restoration <br />plaster systems” when planning and implementing <br />restoration work. <br />Please observe a current EU safety data sheet. <br />GISCODE: ZP1</p> <p>Advice: <br />• P rotect areas not to be treated from the effects of <br />THERMOPAL-SR24. <br />•V <br /> ery damp substrates may cause a lengthening of the <br />waiting time before surfaces can be roughened.</p> <p>Measures taken dependent on the degree of salting in accordance with WTA <br />Degree of salting 1)</p> <p>Measures taken</p> <p>low</p> <p>1.
