For <br />uncoupling ceramic finishes from damaged, cracked <br />but load-bearing substrates, for covering disruptive <br />intermediate movement joints, which are to be relocated <br />in the final finish and for levelling differing construction <br />heights and recesses (e.g. the transition between old tiled <br />finishes to plastered areas when renovating). The use <br />of STEPBOARD 4 mm is possible on heated substrates <br />without appreciable heat loss. STEPBOARD 9 mm and <br />15 mm possess heat insulating properties. Beneath thinsection warm water or electric surface heating systems, <br />when using 4 mm board the efficiency is increased by <br />approx. 30%, approx. 50% with the 9 mm board and in <br />combination with the 15 mm board by approx. 60%.</p> <p>STEPBOARD is an easy to use uncoupling and <br />renovation board with high resistance to compression <br />and exceptional impact sound deadening properties. The <br />uncoupling action is due to the reduction of shear forces <br />through plastic deformation within the board. <br />Areas of application: <br />STEPBOARD is installed for permanent uncoupling <br />and impact sound reduction beneath ceramic tiles and <br />slabs, natural and agglomerated stone in internal areas.</p> <p>Unit <br />Measure</p> <p>STEPBOARD <br />4 mm</p> <p>STEPBOARD <br />9 mm</p> <p>STEPBOARD <br />15 mm</p> <p>Weight</p> <p>kg/m2</p> <p>3,2 ± 5 %</p> <p>6,3 ± 5 %</p> <p>10,5 ± 5 %</p> <p>Thickness</p> <p>mm</p> <p>4 ± 0,5</p> <p>9 ± 0,5</p> <p>15 ± 0,5</p> <p>Format</p> <p>cm × cm</p> <p>100 × 60 ± 0,1</p> <p>100 × 60 ± 0,1</p> <p>100 × 60 ± 0,1</p> <p>Pressured strength, DIN 53456</p> <p>N/mm</p> <p>15</p> <p>10</p> <p>10</p> <p>Bending strength, DIN 53453</p> <p>N/mm2</p> <p>4</p> <p>2</p> <p>2</p> <p>Bending E-module, DIN 53452</p> <p>MN/m</p> <p>ca. 240</p> <p>ca. 100</p> <p>ca. 100</p> <p>Breaking strength, DIN 53457</p> <p>N/mm</p> <p>6</p> <p>6</p> <p>6</p> <p>Permissible traffic load in accordance with DIN 1055</p> <p>kN/m</p> <p>5</p> <p>5</p> <p>5</p> <p>Thermal conductivity λ, DIN 52612</p> <p>W/mK</p> <p>0,11</p> <p>0,10</p> <p>0,8</p> <p>2</p> <p>2</p> <p>2</p> <p>2</p> <p>Thermal resistance R, without covering to DIN 52 612 m²K/W</p> <p>0,04</p> <p>Coefficiency of linear expansion α0</p> <p>K</p> <p>2,75 × 10</p> <p>2,51 × 10</p> <p>Impact sound reduction level ∆Lw with <br />a ceramic floor finish** <br />with tiles bonded</p> <p>dB</p> <p>13</p> <p>13</p> <p>14</p> <p>dB</p> <p>–</p> <p>–</p> <p>20</p> <p>Efl</p> <p>Efl</p> <p>Efl</p> <p>with tiles loose laid</p> <p>-1</p> <p>0,09 <br />-5</p> <p>Reaction to fire in accordance with DIN EN 13501-1</p> <p>0,19 <br />-5</p> <p>2,10 × 10-5</p> <p>** baseline test value in accordance with DIN ISO 140-8 and DIN ISO 717-2</p> <p>1/4</p> <p>26/17</p> <p>Technical Data: <br />Basis: <br />Polyester fibre <br />Colour: <br />green <br />Packaging: 15mm (60 cm ×1m): 60 boards/E.-Pal. = 36.0m2</p> <p>as a bonded construction on the following named <br />substrates is carried out with the flexible thin-bed adhesives <br />MONOFLEX-XL, LIGHTFLEX or SOLOFLEX.

Clean old well bonded <br />flooring and roll on ASO-Unigrund-S. Uneven areas <br />can be levelled with SOLOPLAN-30-PLUS, SOLOPLANFA or ASO-NM15 (calcium sulphate based, for use <br />on calcium sulphate based screeds). Once the primer <br />or the levelling compound has dried, trowel apply <br />the appropriate thin-bed adhesive with a 6–10 mm <br />notched trowel. The boards are laid into the wet <br />adhesive within the open time and pushed tight up <br />against one another avoiding cruciform joints. Directly <br />after laying the boards, beat them into position so that <br />a void-free and fully wetted bedding is achieved. In so <br />doing, ensure that no adhesive appears between the <br />board joints. Once the adhesive has dried, tape over <br />the board joints with a standard adhesive tape approx. <br />20–50 mm wide. <br />•• Bonded to timber substrates such as floorboards, <br />chipboard, OSB boards and parquet as an impact <br />sound deadening and uncoupling board (only <br />STEPBOARD 9 mm and 15 mm) <br />Timber substrates must be clean, dry and load-bearing.</p> <p>Substrate preparation: <br />The substrate must be dry, load-bearing and free from <br />separating substances. Suitable substrates on floors are <br />e.g. concrete, cement-based screeds, calcium sulphate <br />based screeds, magnesite screeds as well as old, well <br />bonded ceramic tiled finishes and natural stone. Calcium <br />sulphate based substrates must be abraded, dry <br />(< 0.5% in accordance with the CM method on unheated <br />substrates; < 0.3% in accordance with the CM method on <br />heated substrates) and primed with ASO-Unigrund-S. <br />Refer to the additional technical information No.14 in the <br />annex. <br />Product application: <br />STEPBOARD can be cut with a hand-held circular saw <br />(e.g. Ø 150 mm, 48 teeth hard metal or 60 teeth chrome <br />plated), a jigsaw (large swing, wood blade) or a carpet <br />knife. To prevent sound bridges and restraint, lay the <br />boards with a min. 5 mm gap against adjoining structures, <br />supports or interruptions etc. Here we recommend the <br />edge isolating strip RD-SK50. It is possible to lay the <br />15 mm STPEPBOARD floating on flat, load-bearing <br />mineral-based substrates. Here the impact sound <br />deadening is further increased. With this method, the butt <br />joints in the boards are covered with standard adhesive <br />tape (approx. width 50 mm). Installing STEPBOARD</p> <p>2/4</p> <p>26/17</p> <p>Subsequent floor/wall finishes on <br />STEPBOARD: <br />Once the adhesive has hardened, the final finish can be <br />fixed to the STEPBOARD. In wet duty areas (moisture <br />exposure classes A0 and A in accordance with the current <br />ZDB data sheet*) install a bonded waterproof membrane <br />such as AQUAFIN-2K, AQUAFIN-2K/M or AQUAFINRS300 before fixing the surface finish. <br />•• Tiles and slabs <br />For the installation of ceramic tiles and slabs e.g. white <br />bodied and red bodied earthenware, vitrified, those <br />with low water absorption <0.5% (porcelain), mosaic, <br />clinker and non-moisture sensitive natural stone to <br />STEPBOARD, the following thin-bed adhesives can be <br />used: LIGHTFLEX, MONOFLEX-XL, MONOFLEX-FB and <br />SOLOFLEX. <br />•• Natural stone <br />For the installation of sensitive natural and <br />agglomerated stone tiles we recommend: CRISTALLITflex, CRISTALLIT-MULTI-flex.</p> <p>Replace damaged areas and screw fix as necessary. If <br />needed, seal any joints in the timber substrate, between <br />floorboards with a conventional acrylic sealant. <br />Chipboard or OSB must be linked together, screwed <br />and glued. Where necessary, abrade floorboards <br />and parquet and prime with ASO-Unigrund-S. Uneven <br />areas can be pre-levelled with the fibre-reinforced floor <br />levelling compound SOLOPLAN-FA up to 20 mm in <br />one layer. Once the primer or levelling compound is <br />dry, trowel out the appropriate thin-bed adhesive with a <br />6–10 mm notched trowel. The boards are laid into the <br />wet adhesive within the open time and pushed tight up <br />against one another avoiding cruciform joints. Directly <br />after laying the boards, beat them into position so that <br />a void-free and fully wetted bedding is achieved. In so <br />doing, ensure that no adhesive appears between the <br />board joints. Once the adhesive has dried, tape over <br />the board joints with a standard adhesive tape approx. <br />20–50 mm wide. <br />•• Bonded to plaster/render, concrete and masonry work <br />as a renovation board for walls <br />When using STEPBOARD on walls e.g. for levelling <br />out recesses beneath tiles, the substrate must be sound, <br />load-bearing, free from old paints and suitable as a <br />substrate for tiling. Prime absorbent and lightly sanded <br />substrates with ASO-Unigrund. Once the primer is dry, <br />trowel out the appropriate thin-bed adhesive with a <br />6–10 mm notched trowel. The boards are laid into the <br />wet adhesive within the open time and pushed tight up <br />against one another avoiding cruciform joints. Directly <br />after laying the boards, beat them into position so that <br />a void-free and fully wetted bedding is achieved. In <br />so doing, ensure that no adhesive appears between <br />the board joints. At the transition between the old <br />surface finish/STEPBOARD, cover the joint created by <br />incorporating a conventional alkali resistant glass fibre <br />mesh into the thin-bed adhesive used.</p> <p>Important Advice: <br />•• The installation of STEPBOARD is a special construction <br />method. We therefore recommend that this special <br />construction method is contractually agreed. <br />•• Perimeter and structural movement joints are to be <br />brought through or inserted at the designed location <br />and stopped with suitable material e.g. edging strips. <br />Always incorporate movement joints in doorways/ <br />thresholds. <br />•• STEPBOARD 9 mm and 15 mm possess thermal <br />insulating properties and are therefore only <br />conditionally for use on heated constructions or <br />are unsuitable. The total thermal resistance of the <br />construction should not exceed 0.15 m²K/W. Refer <br />also to: Guideline No.: 9 “Use of floor coverings over <br />surface heating/cooling – positioning and advice” <br />from the Bundesverband Flächenheizungen und <br />Flächenkühlung e.V.!</p> <p>3/4</p> <p>26/17</p> <p>•• Refer to the technical data sheets of the applied <br />waterproofing materials, smoothing compounds, <br />adhesives as well as the installation instructions of the <br />manufacturer of the surface finish. <br />•• When installing natural or agglomerated stone <br />tiles, refer to the specific properties of the product <br />(discolouration, risk of curling etc.) and the installation <br />recommendations of the manufacturer. We recommend <br />carrying out a trial adhesion. <br />•• Refer to current relevant regulations!
