M220 快速修补砂浆

用途与施工

M220快速修补砂浆是一种用于室内修补的早凝快干、抗垂流的特种功能性砂浆。该产品干固很快，固化后可提供适宜的砂浆强度和硬度。在20℃环境下,工作时间约15分钟,2小时即可硬化上人行走,继续进行其它施工。<br>快硬、快干、不垂流；<br>室内、室外均可使用，2小时后可进行后续施工；<br>混凝土基层、水泥砂浆基层的孔洞、坑槽、缝隙等缺陷的快速修补。<br>整平和修补室内楼梯踏步、普通砂浆基面、混凝土地面等；填补墙面、天花板等的孔洞；修复门窗框架的四周基面；填补管道周围孔隙；可镘整坡道,从坡底薄边可镘整到正常厚度；可制作墙地面转角处的圆弧踢脚线、树脂地面施工前的基面修补。<br>M220快速修补砂浆可用于干燥或潮湿基面，但基面必须是坚实的，并且无灰尘、油污和其它有碍接着物。旧有基面需先去除表面污物，再用机器进行打磨（如研磨机、喷丸机、角磨机、钢刷等），去除表面污染物打磨掉浮尘暴露出坚实的混凝土基面以确保修补砂浆与基面形成最大的粘结强度。<br>对于多孔吸水性好的表面如混凝土、普通砂浆基面、砖等可不用底涂剂,除非基面吸水率太大。<br>用于直接与土壤接触的地面时,原设计应含防潮膜处理。<br>1、在洁净的搅拌桶中加入适量的清水，并倒入粉剂，进行机械搅拌直至生成无结块、抗垂流的浆体，避免加入过量的清水。在23°C工作环境下,工作时间为10-15分钟，但随着温度的升高和降低,工作时间也随之缩短和延长；<br>2、表面修补厚度10mm以下，直接使用拌和的浆料，用镘刀进行表面平整度修补；修补孔洞、裂缝和破损区域时,给镘刀施以一定压力，让修补砂浆浆料充分润湿并牢固接触基层表面；<br>3、表面修补厚度10mm-30mm之间，可在粉料中加入约1/3体积的(粒径0.5-1.0mm)干净粗砂或最多同等体积比的3-5mm单粒径颗粒骨料，局部修补超过20mm的深孔和裂缝，可加入最多同等体积比的5-10mm单粒径颗粒骨料，修补后若表面较粗糙可用未加入骨料的M220浆料进行第二遍施工以达到所期望的平整表面；<br>4、修补后15-20分钟，以海绵沾水湿润表面后再以镘刀收光，待修补区域硬化,即可进行后续自流平精找平施工。<br>本产品须在5℃以上使用；<br>避免在搅拌使用中吸入粉尘。避免直接接触眼睛和皮肤，施工时，请配戴相应的防护面具、手套和护目镜。<br>25kg或5kg复合纸袋包装。本品须储存于室内阴凉干燥处，防止受潮。<br>储存期6个月。<br>M220 Rapid Repair Mortar<br>Product Description:<br>M220 rapid repair mortar is a kind of using for indoor repair early coagulation quick drying, special functional vertical flow resistance mortar. The product dry solid quickly and can provide you the suitable mortar strength and hardness. At 20℃ environment, work time is about 15 minutes, 2 hours hardening walking here, succeeded to other construction.<br>Characteristics：<br>Fast hard, fast dry, no vertical flow;<br>Both indoor and outdoor can be used, and follow-up construction can be carried out after 2 hours;<br>Concrete base, cement mortar base of holes, pits, gaps and other defects of rapid repair.<br>Scope of application:<br>Leveling and repairing indoor stair steps, common mortar base surface, concrete floor, etc. Fill a hole in a wall, ceiling, etc; Repair the base of the window frame; Fill the pores around the pipe; Can trowel the slope, from the bottom of the thin edge can be trowel to normal thickness; Can make wall floor corner arc skirting line, resin floor before the construction of the base surface repair.<br>Substrate Prepare:<br>M220 can be used for the dry or wet base level, but the base must be solid, and free of dirt, oil and other hazardous to then. Old base need to remove surface dirt, and then use machine for grinding (such as grinding machine, shot blastinzg machine, grinder, steel brush, etc), to remove surface contaminants polished away dust exposed solid concrete base to ensure M220 with base to form the largest bond strength.<br>Good water imbibition for porous surface such as concrete, ordinary mortar base, brick can be coated, plane unless is bibulous rate is too big.<br>When used in direct contact with the soil ground, the original designs should be moistureproof film processing.
