Remove old, damaged plasters, paints or coatings from the substrate up to 80 cm above the visible damaged area or the area delimited through <br />inspections. The substrate must be prepared so that it is load-bearing. <br />2. Pre-treat it with ESCO-FLUAT in case of salt contamination. Apply a semi-covering splatterdash coat of THERMOPAL-SP as a bond coat (degree <br />of coverage approx. 50%). In conjunction with mineral waterproofing slurries, apply the adhesive splatterdash coat over the entire surface with <br />100% coverage.</p> <p>Application <br />Measures depending on the degree of salting after WTA</p> <p>Mixing <br />1. <br />2. <br />3. <br />4.</p> <p>Pour the required quantity of water into a clean mixing bucket. <br />Completely add the powder and mix until homogeneous and free from lumps. <br />The mixing time is ca. 3 minutes. <br />After a short activation time, stir again.</p> <p>Application <br />1. <br />2. <br />3. <br />4. <br />5. <br />6. <br />7.</p> <p>THERMOPAL®-SR24 can be applied on the surface in a single application step with a layer thickness up to 30 mm. <br />For thicker layers, render in several layers. <br />In this case, strike off the previous layer with a plasterer’s darby, and immediately after stiffening, roughen up horizontally and allow to dry. <br />Striking off is done with a suitable tool (float, trowel or plasterer’s darby), depending on the application, within the pot life. <br />After sufficient standing time, the surface may be felt boarded matt damp or rubbed down. <br />Alternatively, the surface can also be treated with a grid float. Grid floating is performed depending on the ambient conditions. <br />If necessary, the plaster surface can be overcoated after one day with THERMOPAL® FS33 fine mortar.</p> <p>Storage conditions <br />Storage <br />Store in a cool and dry place. Min. 12 months in the original canister.

The inlay of the plastering fabric is applied in the upper third of the plaster layer. <br />With low strength substrates, a corrosion-resistant plaster base must be attached mechanically to the substrate prior to plastering. (Cannot be <br />used with internal waterproofing). <br />Highly vapour permeable dispersion silicate paints must be used for the colour design.</p> <p>Observe applicable safety data sheet! <br />GISCODE: ZP1 <br />Explanations <br />Conformity / Declaration / Verification</p> <p>The rights of the buyer with regard to the quality of our materials are based on our terms and conditions of sale and delivery.
