Cut STEPBOARD boards with suitable tools. <br />2. Lay the boards with a gap of ≥ 5 mm to the adjacent building components (supports, assembly parts, etc.) in order to prevent acoustic bridges / <br />straining. We recommend the RD-SK50 edging strips for this. <br />3. STEPBOARD is laid using the MONOFLEX-XL, LIGHTFLEX or SOLOFLEX thin-bed mortars or SOLOFLEX in thin-bed laying. The remaining surface <br />coating work can be performed after approx. 24 hours. <br />4. For fast building progress, gluing with the SOLOFLEX-fast, CRISTALLIT-FLEX rapid setting thin-bed mortars or the MONOFLEX-FB rapid setting flowbed mortar is possible. The surface coating can be applied after approx. 3–4 hours here.</p> <p>Application as a bonded impact sound and decoupling panel <br />1. <br />2. <br />3. <br />4.</p> <p>After the primer / levelling compound has dried, apply the corresponding thin-bed mortar with a 6–10 mm notched trowel to the substrate. <br />Insert the boards into the fresh adhesive mortar and butt-join them together. Avoid junctions. <br />Tap the laid boards so that bedding covering the whole area completely is ensured. No adhesive mortar may get between the board joints. <br />After the adhesive mortar has dried, cover the butt joints with commercially available masking tape (approx. 20–50 mm).</p> <p>Application as a bonded impact sound and decoupling panel on wooden substructures <br />1. <br />2. <br />3. <br />4. <br />5. <br />6. <br />7. <br />8. <br />9.</p> <p>Replace damaged areas in the wooden floor or use additional screws if necessary. <br />Close any joints between boards using a commercially available acrylic jointing compound. <br />Chipboard or oriented strand boards must be laid bonded, screwed and glued. <br />Sand the floor boards and parquet, and prime with ASO-Unigrund-S. <br />Surface irregularities can be compensated for using the SOLOPLAN-FA fibre reinforced floor levelling compound up to 20 mm in one application <br />step. <br />After the primer / levelling compound has dried, apply the corresponding thin-bed mortar with a 6–10 mm notched trowel to the substrate. <br />Insert the boards into the fresh adhesive mortar and butt-join them together. Avoid junctions. <br />Tap the laid boards so that bedding covering the whole area completely is ensured. No adhesive mortar may get between the board joints. <br />After the adhesive mortar has dried, cover the butt joints with commercially available masking tape (approx. 20–50 mm).</p> <p>Application as a renovation panel on walls <br />1. If using STEPBOARD in the walls (e.g. to compensate for recesses under tiles), the application substrate must be firm, load-bearing, free of old <br />paints and suitable as a substrate for tiling. <br />2. After the primer / levelling compound has dried, apply the corresponding thin-bed mortar with a 6–10 mm notched trowel to the substrate. <br />3. Insert the boards into the fresh adhesive mortar and butt-join them together. Avoid junctions. <br />4. Tap the laid boards so that bedding covering the whole area completely is ensured. No adhesive mortar may get between the board joints. <br />5. In the transition area from the old covering and STEPBOARD boards, overcoat the joint that occurs by inserting commercially available, alkaliresistant glass scrim with the thin-bed mortar used.</p> <p>Storage conditions <br />Storage <br />Dry and horizontal. 24 months</p> <p>Disposal <br />Product leftovers can be disposed of in household waste.</p> <p>SCHOMBURG GmbH & Co.

We recommend agreeing on the design separately. <br />The STEPBOARD 4 mm can be used on heated substrates without appreciable heat losses. STEPBOARD 9 mm and 15 mm have thermal <br />insulating properties. Under thin-layered hot water or electrical panel heaters, the effectiveness when using the 4 mm board is increased by <br />around 30%, by around 50% with the 9 mm board and by around 60% in conjunction with the 15 mm board. <br />Border and structural movement joints should be carried over to or installed at the designated location; suitable means (e.g. edge strips) <br />should be used to detach them! Movement joints must always be arranged in door/sill areas! <br />STEPBOARD 9 mm and 15 mm have thermal insulating properties and are therefore only moderately or not suitable for use on heated <br />constructions! The total thermal resistance of the coating structure must not exceed 0.15 m²K/W. Also see: Relevant guideline no. 9 "Use of <br />floor coverings on panel heaters and coolers – requirements and notices" from the Bundesverband Flächenheizungen und Flächenkühlung e. <br />V. (German Federal association for panel heaters and coolers)! <br />Observe the technical data sheets of the products mentioned and the laying instructions from the surface coating’s manufacturer! <br />When laying natural stone and synthetic stone, the product-specific properties of the coating materials (tendency to discolour, risk of curling, <br />etc.) and the laying recommendations of the manufacturer must be taken into account. We recommend carrying out trial laying! <br />Apply the RD-SK50 self-adhesive edging strips to the wall-floor transition and the rising building components in advance.</p> <p>Planning, inspection of substrates and building site circumstances, laying, grouting and subsequent <br />care of the work must be done in accordance with the relevant DIN standards and recognised rules of <br />technology (e.g. the ZDB sheets of the Zentralverband Deutsches Baugewerbe e.V.) in the latest <br />version.</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. Our technical advice team will be happy to advise you <br />in the case of requirements that exceed the scope of the application described here. In order to be binding, a legally binding written confirmation is required. The product description <br />does not release the user from a duty of care. Lay a test area in the event of uncertainty.
