          1.簡介
          本技術簡介就合成橡膠地板的安裝材料選擇向安裝人員給予了建議。內容涉及根據相關歐洲標準分類的各種合成橡膠地板。安裝合成橡膠地板時,必須考慮具體特征。根據成分、處理類型及固化特性對粘合劑類型予以劃分。
          —般備注:
          彈性地面覆蓋物上難免出現因重負荷物引起的、在聚光燈下可見的殘留壓痕。但是,通過選用正確的粘合劑、適量涂覆(使用TKB推薦的缺口尺寸適當的齒形刮刀)、正確處理、選擇適當的座椅/家具滑塊(大而平整的接觸面、無尖銳邊緣)及/或在可移動的家具下設置適用的壓力分配襯底或者使用滾輪(如EN 12529所述W型),可以最大程度地減少所述壓痕。這其中還包括家具使用必須與地板構造相符。
          2. 合成橡膠地板分類
          —般情況下,合成橡膠地板又被稱作橡膠地板。這類地板可為薄板狀或片狀,采用全粘法安裝。
          2.1 符合DIN EN 1817要求的表面光滑的合成橡膠地板
          表面光滑的薄板狀或片狀同質或復合層橡膠地板,其中包括帶木紋或浮飾面以及打磨光滑的底面。對于同質地面覆蓋物而言,耐磨層厚度與總厚度相當。對于異質地面覆蓋物而言,耐磨層厚度應至少為1.0 mm。兩種地面覆蓋物的總厚度皮至少為1.8mm。
          2.2  符合DIN EN 1816要求的表面光滑且底面采用泡沫材料的合成橡膠地板
          表面光滑的薄板狀或片狀同質或復合層橡膠地板,其中包括帶木紋或浮飾面以及采用泡沫材料的底面。耐磨層厚度應至少為1.0 mm,總厚度應至少為3.5 mm。
          2.3  符合DIN EN 12199要求的凸紋橡膠地板
          薄板狀或片狀同質或異質凸紋合成橡膠地板,例如經拉毛的橡膠地板。對于同質地面覆蓋物而言,耐磨層厚度與總厚度相當。對于異質地面覆蓋物而言,耐磨層厚度應至少為1.0 mm。
          2.4  符合DIN EN 14521要求的表面光滑且帶裝飾層的合成橡膠地板
          表面光滑且帶裝飾層的薄板狀和片狀合成橡膠地面覆蓋物,其具有或不具有采用泡沫材料的底面。無泡沫材料底面的地面覆蓋物的總厚度應至少為1.8 mm,帶泡沫材料底面的地面覆蓋物的總厚度應至到>為2.5 mm。
          3 合成橡膠地面覆蓋物用粘合劑
          3.1  粘合劑類型
          3.1.1  分散粘合劑
          分散粘合劑是將有機粘合材料分散在水、無機填料及添加劑中而得到。固化基于物理過程(即粘合劑中所含的水蒸發)而發生。分散粘合劑的性能主要受安裝環境條件的影響。高溫及/或低濕度會加速固化,低溫及,或高濕度會推遲固他。
          若合成橡膠地板粘合時只需在一面涂抹分散粘合劑,則需要使用吸水性基材。在基材上涂抹時,應使用專用齒形饅刀。
          利用接觸粘合法,來處理接觸型分散粘合劑。在兩面(即預制基材面以及地面覆蓋物底面)均涂抹這種粘合劑,且在安裝地面覆蓋物之前,必須風干至足夠程度。這些粘合劑主要用于小面積安裝,例如樓梯上的底板和地板的安裝。
          3.1.2  反應性樹脂粘合劑
          反應性樹脂粘合劑由具有化學反應性的有機粘合材料、無機填料及添加劑構成。合成橡膠地板用反應性樹脂粘合劑主要為基于聚氨酯或環氧樹脂的雙組分系統,通過化學反應實現固化。這些粘合劑的固化速度主要受粘合劑、基材和地面覆蓋物的溫度的影響。雙組分反應性樹脂粘合劑需要完全遵循混合比要求,并應小心混合。其罐內存放期和開罐后的存放期均較短。
          3.1.3  溶劑基接觸型粘合劑
          溶劑基接觸型粘合劑由已溶解的有機粘合材料、高揮發性溶劑(高達80%X無機填料及添加劑構成。鑒于工作安全性、從用戶及環保角度方面考慮,若技術允許,則盡量減少這些粘合劑的使用。因此,這些粘合劑僅用于樓梯上的底板和地板的粘接。在這些應用中,還可代之以接觸型分散粘合劑和干型粘合劑。
          注:
          出于職業健康與安全方面的考慮,德國Gefahrstoffverordnung (GefStoftV)(有害物質法
          令)以及德國Technische Regeln Gefahrstoffe(TRGS)(有害物質技術條例)61 0中廣泛限制對溶劑含量高的粘合劑的使用。所使用的溶劑是高揮發性的可燃有害制劑。若不錢遵循既定閾值,則必須采取GefStoffV中所述的方法。
          根據關于修改RL 76/769/EC(限制指令)的1348/2008/EC號決議,環己烷含量超過0.1%的氯丁橡膠基接觸型粘合劑在銷售給私人消費者時,只能采用尺寸不超過350 gr的包裝。
          3.1.4干型粘合劑
          干型粘合劑呈薄板狀或帶狀,其兩面均有粘性,寬度不定。干型粘合劑經制造商預先干燥,因此無需因風干、固化及干燥而耗費時間。在正確安裝后,即可承重。
          3.2  粘合劑類型選擇
          3.2.1  選擇標準
          合成橡膠地板安裝用粘合劑的選擇適用如下標準:
          ·地面覆蓋物特征,例如厚度、尺寸或底面
          ·對地板的要求
            一由極端溫度波動或表面受陽光直射(玻璃結構,例如溫室中火玻璃拱頂下)而產生的熱    應力
            一因叉車或升降運送車產生的機械應力
            一表面濕氣(例如因清潔產生的濕氣)
          ·基材類型
            一吸水性基材
            一非吸水性漁材
          3.2.2  具有或不具有泡沫材料底面的、表面光滑的同質和復合層橡膠地板(符合DIN EN 181 6、DIN EN 1817和DIN EN 14521要求的地板)
          對于這些地面覆蓋物,建議使用分散粘合劑。
          3.2.3  同質和異質凸紋橡膠地板(符合DIN EN 1 21 99要求)
          對于這些地面覆蓋韌,建議根據地面覆蓋物厚度和既定用途,使用分散粘合劑或反應性樹脂粘合劑。若地面覆蓋物厚度不超過4.0 mm,則建議使用分散粘合劑。
          若地面覆蓋物厚度超過4.0 mm,且對粘接及非吸水性基材的要求較高,則應使用雙組分反應性樹脂粘合劑。
          3.2.4  型材及樓梯踏板
          對于這些模制品而言,建議使用干型或接觸型分散粘合劑。若技術允許,則盡量減少對溶劑含量高的粘合劑的使用。
          4.合成橡膠地面覆蓋物安裝
          4.1  基材
          TKB技術簡介8“用于安裝地面覆蓋物和鑲木地板的基材評估和制備”以及BEB技術簡介(“基材評估和制備、彈性及紡織地面覆蓋物、層壓元件(層板)、鑲木地板及木塊。受熱及非受熱型地板結構”)中包含所需測試的相關說明詳情及規范。
          4.2  儲存及調溫
          應將合成橡膠地板存放在干燥的地方,若為片狀,則成對放置,上表面或下表面兩兩相對,若為薄板狀,則成卷豎立存放。在安裝前,應在室溫至少為18 ℃、相對濕度不超過75%的環境中,將地面疆蓋物調溫至少24小時。若地板為片狀,則最好將該覆蓋物鋪放在安裝室內或室內的大面積區域,包括切割鑲邊磚片。
          4.3  安裝條件
          相對濕度最好為40 - 65%,但不得超過75%。環境溫度以及安裝材料(例如地面覆蓋物和粘合劑)的溫度不得低于18 ℃。若與DIN 18365存在偏差,則基材溫度不得低于18 0C,以便將安裝及后期使用時的溫差控制在最小。
          在粘合劑固化過程中,溫度升高(例如受陽光直射)時,可能導致地面覆蓋物的尺寸發生改變。因此,應對地面覆蓋物進行保護,使其在安轉過程中及束后,在粘合劑完全固化前,免受陽光直射或其它熱影響因素的影響。—般情況下,客戶應負責確保采取這些必要措施。安裝人員可要求采取這些措施,或者若商定由安裝人員執行這些措施,則應由其執行。
          4.4 粘結
          4.4.1  薄板狀合成橡膠地面覆蓋物的粘接
          在涂抹粘合劑之前,應切除合成橡膠地面覆蓋物的接縫。兩段接縫的重疊長度應為3 cm,工廠切割縫重疊在未切割接縫上。使用尺子(距離切割板縫不超過1 -2 cm間距)和切邊刀或者直刀片(工具刀片),將工廠切割縫拉直,并刻劃底板。邊緣被切下的部分的寬度應約為2 cm。
          若為單層地面覆蓋物,則向下切割邊緣。這樣得到的接縫的底部就會稍大。切勿向上切割,否則可能導孜V形接縫裂開。
          若為雙層地面覆蓋物,則利用鉤型刀片切除底板的需切割部分。建議在安裝好地面覆蓋物后不要切割底部邊緣。
          一定要以無張力的方式將地面覆蓋物放在未固化的粘合劑層中(安裝時不要向下摩擦按壓,但需嚴密粘接),然后向下按及,或用多面滾輪向下滾壓。一定要注意粘合劑是否過期。在將地面覆蓋物放在粘合劑層中時,粘合劑必須仍足夠濕潤,保證能濕潤覆蓋物的整個底面。檢查濕潤情況。
          4.4.2  片狀合成橡膠地面覆蓋物的粘接
          在粘接片狀合成橡膠地面覆蓋物時,最好將片狀覆蓋物鋪放在整個室內或室內的大面積區域,包括切割鑲邊磚片。地面覆蓋物在安裝時,始終不得受到張力。
          4.4.3  型材及樓梯踏板的粘接
          建議使用干型或接觸型分散粘合劑來粘接型材及樓梯踏板。在使用這些粘合劑時,需粘接的元件必須能夠精確配合,否則后期便幾乎不能加以糾正。在安裝結束后,必須立即按壓元件,在整個長度上向下輕輕敲嚴實。
          4.5  接縫密封
          4.5.1  熱密封
          帶泡沫材料底面的地面覆蓋物(符合DIN EN 1816和DIN EN 14521的要求)以及導熱性地面覆蓋物應始終被密封。原則上,對于不帶泡沫材料底面的地面覆蓋物(符合DIN EN 1817、DIN EN 14521和DIN EN 12199的要求)而言,無需密封。若基材容易受濕氣影響以及位于水接觸量大的室內(即頻繁清洗),則在使用分散粘合劑時,必須進行接縫密封。
          只有在粘合劑完全固化后才能執行熱密封,原則上,最早的熱密封時間是24小時后,但最好是2-3天后再進行熱密封(參見制造商的說明X使用特殊銑削工具或開槽工具來打開接縫,打開接縫的寬度應約為3.5 mm,必須仔細清潔接縫。可使用自動熱熔機(焊接線必須在不受力的狀態下穿過機器)或者帶快焊噴嘴的手動焊機來加工焊絲。
          一定要避免超過或低于規定加工溫度的情況。工作速度應使得融化的焊絲能夠輕松地進入磨槽( 2.5 -3.0米/分鐘)采用如下兩個步騾來去除多余材料:
          ·在焊絲尚未冷卻時,用帶修整導向件的鋒利的玄月形切刀來執行第—步去除。
          ·只有在接縫完全冷卻之后,才能進行第二步去除——去掉多余材料,使接縫與地板表面相平,期間依然使用玄月形切刀。
          若沒有玄月形切刀,則可使用合適的修整刀,在去除多余焊絲時,所述修整刀只能在接合區域內執行修整。
          4.5.2  利用單或雙組分接縫密封劑來進行密封
          使用單或雙組分反應性樹脂接縫密封劑,可滿足特殊的接縫密封要求(例如,在實驗室中或者在保健區內)一定要遵循制造商指定的相關說明。

          校對者注釋:
          條目3.2.3 同質和異質凸紋橡膠地板(符合DIN EN 12199要求)
          本條目所述“厚度不超過4.Omm,建議使用分散粘合劑”,這是針對德國而言。德國的粘合劑工業發達,水性分散乳液型粘合劑可以粘貼厚度小于4.Omm的橡膠地板,國內卻沒有這樣的粘合劑。國內水性分散乳液型粘合劑制造商給出的數據為厚度小于2.5mm適用。
          在德國,優成公司有兩款水性粘合劑可以粘貼4.Omm厚度的橡膠地板:KE66和NEW KE
          2000S。優成在中國制造的KE 2000S只能粘貼2.5mm以下厚度橡膠地板,與德國新2000S不同。德國漢高妥善有一款K150水性分散乳液型粘合劑也可以粘貼4.Omm以下厚度的橡膠地板。
          在中國,橡膠地板的黏貼,情況有點復雜。
          首先,德國之外的橡膠地板都或多或少存在粘合劑適配性的問題。不同廠家、甚至同廠家同型號,不同顏色的地板對粘合劑存在敏感的適配性。更有甚者,同一卷地板背襯存在光面和毛面,粘合劑適配性截然不同。
          早在2008年,筆者發現雙組分聚氨酯粘合劑粘不住韓國某品牌的橡膠片材。此后,大規模的測試發現,德國諾拉之外的橡膠地板,或多或少存在粘合劑適配性問題。與此同時,優成公司也發現這個問題,并且將此一問題告知業內。優成公司為此開發出了對橡膠地板適應性更好的雙組分環氧樹脂粘合劑KR420。特朋緊追其后乜開發出類同類產品。此類粘合劑對絕大部分橡膠地板具有適配性。
          遺憾的是,在2011年之前,作為行業領袖的漢高妥善部門,對此一無所知,未經適配性測試,銷售人員無知的向地板商推銷R710雙組分聚氨酯粘合劑,導致整個行業對此了解不多,出現粘結力問題以后,茫然不知所措。
          施工橡膠地板之前,只要不是德國諾拉產品,建議進行適配性測試,以便確定粘合劑針對性的粘結強度。
          適配測試很簡單:地板條切割成5cm寬度,長度超過30cm即可。頭部3cm不粘貼,企圖粘貼后重物壓實,基板建議采用木板。養護溫度200C一230C,5~7天后使用電子彈簧秤90度角剝離地板條。按照EN1372標準,剝離力超過10kg為優秀,該型粘合劑可以用于橡膠地板安裝。
          針對一個品牌某—個型號的測試,并非一次即可。建議每個批次都要測試。尤其是原產亞洲的產品。

          Residual indentations visible under a spotlight, caused by high punctual loads, can never be
          completely avoided with resilient floor coverings. However, they can be minimized by selecting the right adhesive, application quantity (use of TKB recommended notched trowel with suitable notch sizes),  proper processing and choice of appropriate chair/furniture sliders (large and level
          contact surface, no sharp edges) and/or use of suitable pressure distribution underlays under
          movable furniture or rollers (type W according to EN 12529). This also includes that future use must comply with floor construction.
          2. Classification of Elastomer Flooring
          Commonly, elastomer flooring is also called rubber flooring. This type of flooring is available in form of sheets or tiles and is fully bonded during installation.
          2.1 Elastomer Flooring with smooth Surface according to DIN EN 1817
          Homogenous or heterogenous elastomer flooring in sheets or tiles with smooth surface, including grained or embossed surfaces and smoothed backing. For homogenous floor coverings, the wear layer thickness corresponds to the overall thickness. For heterogenous floor coverings, wear layer thickness shall be at least l.0 mm. The overall thickness of both types of floor covering
          shall be at least l.8 mm.
          2.2 Elastomer Flooring with smooth Surface and Foam Backing according to DIN EN 1816
          Homogenous or heterogenous elastomer flooring in sheets or tiles with smooth surface, including grained or embossed surfaces and foam backing. Wear layer thickness shall be at least l,0 mm with an overall thickness of minimum 3.5 mm.
          2.3 Relief Elastomer Flooring according to DIN EN 12199
          Homogenous or heterogenous relief elastomer flooring in sheets or tiles, e.g. rubber napped
          flooring. For homogenous floor coverings, wear layer thickness corresponds to the overall thickness. For heterogenous floor coverings, the wear layer thickness shall be at least l.0 mm.
          2.4 Elastomer Flooring with smooth Surface and decorative Layer according to DIN EN 14521
          Elastomer floor coverings in form of sheets and tiles with smooth surface with decorative layer, with or without foam backing. The overall thickness for floor coverings without foam backing shall be at least l.8 mm and with foam backing n:inimum 2.5 mm.
          3. Adhesives for Elastomer Floor Coverings
          3.1 Types of Adhesives
          3.1.1 Dispersion Adhesives
          Dispersion adhesives consist of organic binding materials dispersed in water, inorganic fillers and additives. Setting takes place based on a physical process when the water contained in the adhesive evaporates. The setting properties of dispersion adhesives are mainly influenced by the climatic conditions of the installation environment. High temperatures and/or low humidity accelerate, low temperatures and/or high humidity delay the setting process.
          Dispersion adhesives for one-sided application for bonding of elastomer flooring require an absorbent substrate. They are applied with the specified notched trowel on prepared substrate.
          Dispersion contact adhesives are processed using the contact bonding method. They are applied't both sides - the'sprepared substrate and floor covering backing - and must have sufficiently aired before installing the floor covering. They are mostly used for small area installations, e.g. installation of baseboards and flooring on stairs.
          3.1.2 Reaction Resin Adhesives
          Reaction resin adhesives consist of chemically reactive organic binding materials, inorganic fillers and additives. Reaction resin adhesives for elastomer flooring are mainly 2-component systems based onspolyurethane or epoxy resins and cure by chemical reaction. The curing speed of these adhesives is essentially influenced by the temperature of adhesive, substrate and floor covering. 2-component reaction resin adhesives require exact compliance with prescribed mixing ratio and careful mixing. They only have a limited pot life and open time.
          3.1.3 Solvent-based Contact Adhesives
          Solvent-based  contact  adhesives  consist  of dissolved organic binding materials, highly volatile solvents (up t0 80 %), inorganic fillers and additives. From a work safety, consumer and environmental protection perspective, use of these adhesives shall be reduced to the absolute minimum technically necessary. Consequently, their use is restricted to bonding of baseboards and flooring on stairs. For these applications, dispersion contact and dry adhesives are an alternative.
          Note:
          The German Gefahrstoffverordnung (GefStoffV) (Ordinance on Hazardous Substances) and the German Technische Regeln Gefahrstoffe (TRGS) (Technical Rules for Hazardous Substances) 610 massively restrict use of adhesives with high solvent levels for occupational health and safety reasons. The solvents used are highly volatile, flammable and harmful compounds.'sln case the
          existing threshold values can not be safely adhered to, measures prescribed in GefStoffV must be taken.
          According to decision No. 1348/2008/EC to amend RL 76/769/EC (Restriction Guideline), neoprene-based contact adhesives containing more than 0.1 % of cyclohexane, shall only be marketed to private consumers in package sizes of maximum 350 gr.
          3.1.4 Dry Adhesives
          Dry adhesives are sheets or strips which are self-adhesive on both sides and come in rolls of
          varying width. Dry adhesives are pre-dried by the manufacturer and therefore do not require airing, setting or drying time. After proper installation, they are immediatel; load-bearing.
          3.2 Selection of Type of Adhesive
          3.2.1 Selection Criteria
          The following criteria apply for selection of an adhesive for installation of elastomer flooring:
          . Floor covering characteristics such as thickness, size or backing.
          . Demands on flooring
          -  thermal stress caused by extreme temperature fluctuations or direct exposure to sunlight on surface (glass constructions such as in conservatories or under glass domes)
          -  mechanical stress caused by forklifts or lift trucks
          -  moisture on surface (e.g. from cleaning)
          .Type of substrate
          -  absorbent substrate
          -  non-absorbent substrate
          3.2.2 Homogenous and heterogenous Elastomer Flooring with smooth Surfsace, with or           without Foam Backing (Flooring according to DIN EN 1816, DIN EN 1817 and DIN EN 14521)
          For these floor coverings, suitable dispersion adhesives are recommended.
          3.2.3 Relief homogenous and heterogenous Elastomer Flooring (according to DIN EN 12199)
          For these floor coverings, suitable dispersion or reaction  resin  adhesives  are  recommended depending on floor covering thickness and intended  use.  Dispersion  adhesives  are recommended for floor covering thicknesses up to 4.0 mm.
          For floor covering thicknesses of more than 4.0 mm and high demands on bond as well as for non-absorbent substrates, 2-component reaction resin adhesives shall be used.
          3.2.4 Profiles and Stairtreads
          For these moldings, dry adhesive or dispersion contact adhesives are recommended. The use of adhesives with high content of solvents shall be restricted to the absolute minimum technically necessary.
          4. Installation of Elastomer Floor Coverings
          4.1 Substrate
          TKB Technical briefing note 8 "Assessment and Preparation of Substrates for Installation of Floor Covering and Parquet as well as BEB Technical briefing'snote "Beurteilen und Vorbereiten von Untergrunden. Verlegen von elastischen und textilen Bodenbelags;en, Schichtstoffelementen
          (Laminat), Parkett und Holzpflaster, Beheizte und unbeheizte FuBbodenkonstruktionen" ("Assess-
          ment and Preparation of Substrates, Installation of elastic and textile floor coverings, laminated
          elements (laminate), parquet and wood block. Heated and non-heated floor constructions") contain detailed instructions and specifications regarding required tests.
          4.2. Storage and Conditioning
          Elastomer flooring shall be stored in a dry place, tiles in pairs with upper side or underside facing each other, sheets are stored standing in rolls. Before installation, the floor covering shall be conditioned for at least 24 hours at a room temperature of min. 18 0C and a relative humidity
          not exceeding 75 %. For flooring that comes in tiles, it has been proven beneficial to spread out
          covering in installation room or in large parts of the room, including cutting of the border tiles.
          4.3 Installation Conditions
          The relative humidity shall preferably lie between 40 - 65 %, however it shall not exceed 75 %. Ambient air temperature as well as temperature of the installation materials, e.g. floor covering and adhesive shall be at least 18 0C. In departure from DIN 18365, minimum substrate temperature shall be 18 0C in order to keep temperature difference between installation and later use to a minimum. During curing phase of the adhesive, rising temperatures (e.g. exposure to direct sunlight) may cause dimensional changes to the floor covering. Consequently, floor covering shall be protectead from direct sunlight or other thermal effects during and after installation, until adhesive has completeI cured. Generally, it's under the customer's purview
          to ensure these essential measures. Installer may request these measures or perform them himself after having voiced reservations.
          4.4 Bonding
          4.4.1 Bonding of Elastomer Floor Covering in Sheets
          Before applying the adhesive, the seams of elastomer floor covering shall be cut. Both lengths are laid out overlapp;nsg 'for 3 cm, the factoryscut seam overlapping the uncut seam. Using a ruler (max. 1 - 2 cm clearance to cut sheet sesam) and an edge cutter or a straight blade (utility blade) the factory-cut seam is straightened and the underlaying sheet is scribed. The width of the cut edge strip shall be approx. 2 cm.
          With one-layer floor coverings, the cut edge strip is taken off downwards. This results in a seam slightly open at the bottom. Never remove the strip upwards because this might result in a gaping V-joint .
          With two-layer floor coverings, the cut strip of the bottom sheet is removed using a hooked blade. It is not recommended to cut the bottom edge after floor covering is installed.
          The floor covering shall always be placed in the fresh adhesive besd free of tension (no press-down installation but narrow joints), then rubbed down and/or rolled down using a multi-sectional roller. Always observe open time of the adhesive. When placing the floor covering into the adhesive bed, adhesive must still be sufficiently wet to wet the entire backing of the covering. Check wetting.
          4.4.2    Bonding of Elastomer Floor Covering in Tiles
          When bonding elastomer floor coverings in tiles, it has proven beneficial to lay down the tiles in the entire room or in larger areas of the room, including cutting of border tiles. The floor covering shall always be installed free of tension.
          4.4.3    Bonding of Profiles and Stairtreads
          Dry or dispersion contact adhesives are recommended for bonding of profiles and stairtreads. When using these adhesives, the elements to be glued must be fitted exactly since subsequent corrections are almost impossible to perform. After installation, the elements must be immediately pressed and tapped down firmly over the entire length.
          4.5 Seam Sealing
          4.5.1 Thermal Sealing
          Elastomer floor coverings with foam backing (DIN EN 1816 and DIN EN 14521) as well as conductive floor coverings shall always be sealed. Principally, for floor coverings without foam backing (DIN EN 1817, DIN EN 14521 and DIN EN 12199) sealing is not necessary. For substrates sensitive to moisture as well as in rooms with intensive water contact, i.e. frequent wet cleaning, seam sealing is an absolute must when dispersion adhesives are used.
          Thermal sealing shall only be performed after adhesive has fully cured, as a rule after 24 hours at the earliest, but better yet after 2 - 3 days (see manufacturer's instruction). The joints are opened using a special miller or groover over a width of approx. 3.5 mm. The joint shall be carefully cleaned. The welding cord can either be processed using an automatic fuse machine (cord must pass the machine tension-free) or a hand welder with attached quick-weld nozzle.
          Absolutely avoid to exceed or fall short of specified processing temperature. Work at a pace that allows melted cord to easily run into mill groove (2.5 - 3.0 meters/min). Excess material is removed in two steps:
          . The first removal step is performed when welding cord has not yet cooled down using a sharp quarter moon knife with trim guide attached.
          .  The second step takes place only after joints have completely cooled down - excess is
             removed flush to flooring surface, also using a quarter moon knife.
          If no quarter moon knife is at hand, an appropriate trimming knife can be used which will only work in the joint area when removing excess welding cord.
          4.5.2. Sealing with l or 2-component Joint Sealers
          Special requirements for seam sealing, e.g. in laboratory areas or in the healthcare sector, are met by using l- or 2-component reaction resin joint sealers. Alv:ays observe the relevant instructions specified by manufacturer. Relevant Standards and Technical Briefing Notes
