KG · Aquafinstr. 2–8 · D-32760 Detmold (Germany) · Tel. +49-5231-953-00 · Fax +49-5231- 953-333 · schomburg.com <br />2/3</p> <p>03/02/2026</p> <p>Technical data sheet <br />THERMOPAL®-WSP-120 <br />Preparing the surface <br />1. 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. Highly absorbent, chalky or sandy substrates should be primed with AQUAFIN primer. <br />3. Pre-treat it with ESCO-FLUAT in case of high salt content. Apply a semi-covering splatterdash coat of THERMOPAL-SP as a bond coat (degree of <br />coverage approx. 50%). <br />4. In conjunction with mineral waterproofing slurries such as AQUAFIN-1K or AQUAFIN-RB400, apply the adhesive splatterdash coat over the <br />whole area with 100% coverage. <br />5. When using barrier plasters such as ASOCRET-M30, comb the surface horizontally with an 8 mm notched trowel.</p> <p>Application <br />Mixing <br />1. Pour the required quantity of water into a clean mixing bucket. <br />2. Completely add the powder and mix until homogeneous and free from lumps. <br />3. The mixing time is ca. 3 minutes. <br />4. After a short activation time, stir again.</p> <p>Application <br />1. THERMOPAL®-WSP-120 can be applied in a single application step up to 40 mm Layer thickness applied on the surface. <br />2. For thicker layers, render in several layers. <br />3. In this case, strike off the previous layer with a plasterer’s darby and roughen up horizontally. The second layer can be applied directly the <br />following day. <br />4. Striking off is done with a suitable tool (float, trowel or plasterer’s darby), depending on the application, within the pot life. <br />5. After sufficient standing time, remove ridges and unevenness using a trowel back or grid float. Alternatively, the surface can be felted or rubbed <br />down to a matt damp finish. <br />6. THERMOPAL®-WSP-120 should always be overcoated with THERMOPAL-FS33 fine plaster.</p> <p>Fine plaster <br />1. THERMOPAL®-WSP-120 may only be reworked after sufficient air drying. <br />2. Depending on the weather and application thickness, this is achieved after 14-20 days (drying time approx. 2 days per cm of insulating plaster). <br />3. Damp substrates extend the standing time to at least 4 weeks. <br />4. After drying, prime the plaster surface with AQUAFIN® primer. <br />5. Then, rework the plaster surface with the THERMOPAL®-FS33 fine filler in two application steps.</p> <p>Storage conditions <br />Storage <br />Store in a frost-free, cool and dry place. 12 months in the original canister. Promptly use opened container.</p> <p>Notes <br />Protect surfaces that are not to be treated from the effects of THERMOPAL®-WSP-120! <br />Very damp substrates may require longer waiting times before they can be rubbed off. <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 />Under difficult site conditions (e.g. inhomogeneous masonry work, waterproofed masonry work, use in exterior area under changing weather <br />conditions and thick-layer plaster build-ups, etc.), an alkali-resistant glass scrim such as ASO®-RSG can be used to increase the cracking <br />resistance. The inlay of the plastering fabric is applied in the upper third of the plaster layer. <br />Rubbing prematurely or too intensively causes a binder concentration on the surface and can cause stress cracks. <br />Protect from strong solar radiation and draughts. <br />Highly vapour permeable dispersion silicate paints must be used for the colour design.</p> <p>Observe applicable safety data sheet!</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.
