复习思考题
1、钢材预处理包括哪些内容?如何进行 除锈质量检验?
2、如何检测涂层的厚度?
二、钢材预处理检验
② 除锈等级。 钢材表面的除锈等级以代表所采用的除锈 方法的字母Sa、St、FI表示; 如果字母后面有阿拉伯数字,则其表示清 除氧化皮、铁锈和油漆涂层等附着物的程度。 Sa ——喷射或抛射除锈; St ——手工和动力工具除锈; FI——火焰除锈。
二、钢材预处理检验
喷射或抛射除锈前,厚的锈层应铲除。可 见的油脂和污垢也应清除。喷射或抛射除锈 后,钢材表面应清除浮灰和碎屑。
一、概述
在船体的首部,海水对壳体产生较大的流 体动力作用,特别是对速度比较高的船舶。这 使得涂层的工作条件变得十分苛刻。 船体中部的船舷外壳表面受到比首部小的 流体动力作用,但是这个区域的涂层在船靠码 头时特别容易遭到破坏。 船底部位,由于附着海生物,易产生氧浓 差电池而引起坑蚀。海生物的排泄物助长腐蚀 之外,随其积累还会侵入船体涂膜中,从而将 涂膜破坏,也会造成严重后果。
钢板经预处理流水线除锈后,涂车间底漆 前,将标准零位板(尺寸为:70×300×1) 用胶带粘贴在经过抛丸处理的钢板(材)表 面,干燥后取下,用精密的电磁式测厚仪,测 定试验板上的漆膜厚度。
二、钢材预处理检验
试验板的贴置点应具有代表性。 测点的选择:原则上平整表面每10m2左右 检测一点,复杂表面每5 m2左右检测一点,对 于狭小舱室,小型液柜等面积较小的区域或部 件,保证每一自由面3个以上的测点,焊缝表 面、距自由边30mm的范围内和检测困难处都 不必进行检测。 船体涂层的干膜厚度用干膜厚度仪直接在 被涂面检测。检测必须在涂层完全硬化后进行。

船舶防腐蚀技术的基本知识及涂装检验技术

船舶防腐蚀技术的基本知识及涂装检验技术

船舶防腐蚀技术的基本知识及涂装检验技术1、船舶防腐蚀技术之应用海舶及海上设施的腐蚀是影响其寿命的最大的因素之一。

因腐蚀导致结构损坏和破坏,财产甚至生命的损失屡见不鲜。

自上世纪70、80年代起,由于各种因素导致老龄船增加。

同时国,际上对海洋环境污染的关注程度也趋于严格,在1995年底IMO又通过了对专用海水压载舱防腐蚀系统涂装提出的指导性意见。

去年IMO环境保护委员会已通过《国际控制有害船底防污系统公约》,与此配套的相关规则也即将出台。

与此同时,IACS为了顺应这种国际趋势,也加强了对现有老龄船舶的检验要求。

为此,船舶和海上设施的防腐蚀问题开始备受主管机关、检验部门、船东、保险商等的关注。

为了更好地执行IMO的有关规定和为船东在延长船舶寿命提供有效的帮助,同时也为相关各方对检验质量提供较公正技术条件,中国船级社总部在与中国船舶工业涂装技术指导组协调后,编制了,《船舶结构防腐检验指南》。

该《指南》目前已通过审查,近期即将颁布。

这将对船舶防腐蚀技术的提高和延长船舶的寿命发挥积极的作用。

本文将对该《指南》的重点内容进行介绍。

1 通则主要涉及本指南的编制目的和适用范围。

明确编制本指南的目的是为了规范船舶和海上设施防腐蚀作业的控制点和最低适用标准。

本指南主要是用于船舶和海上设施的防腐。

其他结构可参照使用。

通则中定义取自于相关的国家标准和国家正式出版的书刊。

主要有:GB8264—1987《涂装技术术语》、GB 12466一1990《船舶及海洋工程腐蚀与防护术语》、《涂料工业手册》(化学工业出版社2001年9月第l版)。

由于本指南将指导整个舶船防腐工作,指明三种不同的检验种类,可以对使用本指南选择检验方法提供方便。

2 防腐设计/施工单位及人员要求为保证防腐蚀工程的质量,防腐蚀工程的设计/施工单位以及人员应有一定的资质,这是一般的常识。

其原则为:(1) 设计/施工单位必需每一项目各有二个以上的技术人员和质量检查员;(2) 应有完善的质量体系,以保证有关的要求得到切实执行,其中包括IS09000的质量认证;(3) 单位所具有的设备和器材应满足设计和施工的要求。

船舶涂装膜厚检测要求

船舶涂装膜厚检测要求

船舶涂装膜厚检测是指对船舶表面涂层的厚度进行测试和评估,以确保涂料的质量和船舶表面的保护效果。

涂层膜厚的测量对于保护船体免受海水侵蚀和氧化非常重要,因此船舶涂装膜厚检测是船舶维护和保养中必不可少的一项工作。

船舶涂装膜厚检测需要使用测量仪器,如涂层厚度计或圆锥体膜厚计等。

这些仪器可以通过非接触或接触式测量方法确定涂层厚度。

在进行涂层检测时,应注意以下事项:
1.在检测之前,应清理船舶表面,以确保膜厚检测的精确性。

2.应将测量仪器校准到正确的基准线,并根据不同类型的涂料选择不同的测量方法和测量仪器。

3.在测量涂层膜厚时应取多个样本,在船舶表面不同部位进行检测,以获得更准确的数据。

4.将膜厚数据记录下来,以便后续测量和比较。

涂装和内装检验

涂装和内装检验

第七章涂装和内装检验第一节涂装检验在自然界,金属腐蚀的产生是一种普遍的现象,它遍及于工业、农业的各行各业中,如机械、化工、建筑、矿产、轻工、国防、造船等等。

由于腐蚀所造成的损失,一般可分为直接损失和间接损失两类。

直接损失是指因腐蚀而造成的金属材料的损耗及除锈涂装费用,它是能估算的。

而间接损失指的是腐蚀造成原材料的流失、结构体的强度、机械性能发生变化、产品的污染、效率的降低、停工减产以及火灾、爆炸、人工伤亡、金属结构倒塌等,这是很难估计的。

因此世界各国的防腐蚀工作者都非常重视对腐蚀的研究,积极采取各种防腐措施,以尽量减少腐蚀所造成的损失。

造船设计对船体构件腐蚀限度的习惯做法是增加船体构件的厚度,但是采取这种方法有以下弊端:一是增加了新船的重量,使船舶的航速降低,从而提高了船舶的营运成本;二是由于钢材重量的增加,提高了船舶的建造成本,使造船的初始投资增加;另外,由于不重视油漆工作的质量,加剧了海水对钢板表面的腐蚀,使船舶的维修费用增加。

因此,船舶的设计工作者和建造者的主要指导思想是在保证船舶的强度和刚度的前提下,少留或不留腐蚀裕度,以最大可能地降低船舶的重量。

于是采用钢材表面预处理工艺和提高油漆的防腐性能越来越被造船业所重视。

一、钢材表面处理质量检验造船用的钢材种类很多,大多数是热轧钢材。

从钢材冶炼厂刚出来的钢材其表面基本上完整地覆盖着一层氧化皮,这样的钢材如果直接涂上涂料则会在一定的条件下导致涂层随氧化皮一起脱落。

因此,涂装前钢材表面处理质量控制主要包括两个方面的内容,即钢材表面的清洁度和粗糙度。

随着科学技术的发展和检测手段的提高,现在对粗糙度的评定一般都是通过机械或电子粗糙度检测仪进行测定。

当然这些检测仪的检测标准是按国标来确定的。

但是,到目前为止,还没有一种有效的检测仪能进行清洁度的评定,还只能靠目测来进行。

国标对于粗糙度的规定是套用国标ISO8502,该标准配有多张标准照片对经喷射除锈和手工动力工具除锈后的钢材表面进行了规定,对某个处理后的表面进行清洁度的评定一般应采用目测加标准照片对比进行评定。

NACE考试大纲-涂装

NACE考试大纲-涂装

关于NACE考试1美国的国家腐蚀工程师协会NACE(National Association and Cross ion Engineer )最早是在1943年由研究管道腐蚀的工程师所成立的,几十年来已经逐渐扩展到几乎所有其它工业部门的腐蚀研究领域。

目前已经是全美最权威的腐蚀与防腐蚀研究机构。

NACE培训主要包括一般的教育课程(General Education Course),阴极保护认证课程(Cathodic Protection Certification Program)以及涂装检验(Coating Inspection)。

涂装检验又包括涂装检查程序(CIP),CIP桥梁1天专业课程、船舶涂料检查(Marine Coating Inspection)防腐蚀涂料和衬里(Protective Coatings and Linings)、离岸工程腐蚀评估培训(Offshore Corrosion Assessment Training)以及涂层与阴极保护(Coatings in conjunction with cathodic protection)。

这其中最主要的课程就是CIP (Coating Inspection Program)涂装检查。

一个完整的涂装检验课程NACE CIP针对不同内容来划分其等级,以前分为三个课程,现在已经合并为两个课程。

其中CIP I第一个课程又可以分为6天的课堂学习课程以及3天的考试课程。

如果要求参加认证考核的人员已经在家完成光盘上面80%的内容,就无需事先进行培训了,这样就增加学习的机动性并且省去了很多费用。

光盘共有5张,包括以下内容:1. 表面处理module one surface preparation2. 涂料施工module two coating application3. 检查module three inspection4. 健康和安全module four health & safety5. 涂料类型module five coatings types其中6天课程包括以下主要内容:涂料介绍Coatings Introductionλ固化机理Curing Mechanismsλλ检查员的角色Role of the Inspector环境检测仪器Environmental Test Instrumentsλ检查程序λInspection Procedures非破坏性检查仪器Nondestructive Test Instrumentsλ涂料规格书Coating Specificationsλ文件Documentationλ表面处理处理和标准Surface Preparation and Standardsλ施工程序Applicationλ Procedures涂层缺陷Coating Failuresλ户外实验室Field Labλ工前会议Pre-job Conferenceλ材料安全数据手册和产品技术手册MSDS and ProductλData Sheet Review日志文件Logbook Documentationλ环境条件测量λ Measurement of Ambient Conditions非破坏性测试和检查Nondestructive Testing andλ Inspection团队训练Team Exercisesλ案例学习Case Studiesλ图 通过CIP I 级培训认证后所发的证书样式样(正反面)CIP II的主要内容包括:除湿λ抛丸喷射清理λ水喷射λ个人特点Personal profile systemλ数学应用λ非破坏性检查仪器λ破坏性检查仪器λλNACE 标准衬里和特殊涂层λ特殊施工设备λ混凝土和检查λ表面处理,涂层和特殊底材的检查λ实践应用λ厚屏蔽衬里介绍λ管道涂层λFBE 管道涂层λ涂层的维修操作λ检查和报告λ涂层类型和检查标准λ阴极保护λ热浸镀锌λ金属热喷涂λ专用涂层和施工λ涂层调查λ专门的测试和测试设备λ图 通过CIP II图 通过CIP I 级培训认证后所发的证书样式样(正面)在成功完成Peer Review后,检查员应能:•有权力、有信誉和有责任进行涂装检查工作•指导“未获证”涂装检查员的工作•使用“NACE持证涂装检查员”的头衔美国防腐工程师协会涂装检查员认证CIP-I课程表面处理初级单元涂料施工的表面处理对于实际使用的每一种涂装工序,例如:磷化处理,镀锌,电镀或涂漆-待涂表面的最初清洁和处理都是工序中的一个步骤,该步骤决定了以后的涂装体系成功与否。

【摘要】@@ 船级社参加船舶涂装检验的必要性rn船舶航行于江河湖海之上,环境对船体结构材料的侵蚀是不可避免的.给船体构件涂上一层防腐涂层,是控制和减少结构材料腐蚀程度的最经济有效的手段之一.涂层能提高船体结构的防腐能力,对保证船体结构的安全有着重要的意义.90年代以来,随着IMO和IACS对此问题的重视,ESP、CAS等一系列规定先后出台,指导验船师和船东对船体的外板、甲板、货舱和压载舱的涂层状况进行检验和评估.各船级社在海洋工程方面都已将对结构涂层的检验要求纳入了船级条件,尽管对船舶涂装检验的要求还未被强制规定为入级条件,但也纷纷组织人力进行研究,DNV船级社还制订、颁布了对新造船涂层配套和涂装施工质量控制的指南.总的发展趋势是船级社将会更加广泛地介入船舶涂装领域.

Efflorescence results from leaching of lime or calcium hydroxide out of a permeable concrete mass over time by water, followed by reaction with carbon dioxide and acidic pollutants.2Fin: A narrow linear projection on a formed concrete sur-face, resulting from mortar flowing into spaces in the form work.1Finish: The texture of a surface after consolidating and fin-ishing operations have been performed.1Finishing: Leveling, smoothing, consolidating, and other-wise treating surfaces of fresh or recently placed concrete or mortar to produce desired appearance and service.1Hardener (Concrete): A chemical (including certain fluoro-silicates or sodium silicate) applied to concrete floors to reduce wear and dusting.1High-Pressure Water Cleaning (HP WC): Water cleaning performed at pressures from 34 to 70 MPa (5,000 to 10,000 psig).3High-Pressure Waterjetting (HP WJ): Waterjetting per-formed at pressures from 70 to 210 MPa (10,000 to 30,000 psig).3Honeycomb: Voids left in concrete due to failure of the mortar to effectively fill the spaces among coarse aggregate particles.1Laitance: A thin, weak, brittle layer of cement and aggre-gate fines on a concrete surface. The amount of laitance is influenced by the type and amount of admixtures, the de-gree of working, and the amount of water in the concrete.2Lining: See Protective Coating or Lining System.Placing: The deposition, distribution, and consolidation of freshly mixed concrete in the place where it is to harden.1Porosity: Small voids that allow fluids to penetrate an otherwise impervious material.Protective Coating or Lining System (Coating): For the purposes of this standard, protective coating or lining sys-tems (also called protective barrier systems) are bonded thermoset, thermoplastic, inorganic, organic/inorganic hy---`,,,,,-`-`,,`,,`,`,,`---NACE No. 6/SSPC-SP 13brids, or metallic materials applied in one or more layers by various methods such as brush, roller, trowel, spray, and thermal spray. They are used to protect concrete from degradation by chemicals, abrasion, physical damage, and the subsequent loss of structural integrity. Other potential functions include containing chemicals, preventing staining of concrete, and preventing liquids from being contaminated by concrete.Release Agents (Form-Release Agents): Materials usedto prevent bonding of concrete to a surface.1Sealer (Sealing Compound): A liquid that is applied as a coating to a concrete surface to prevent or decrease the penetration of liquid or gaseous media during exposure. Some curing compounds also function as sealers.Soundness: A qualitative measure of the suitability of the concrete to perform as a solid substrate or base for a coat-ing or patching material. Sound concrete substrates usually exhibit strength and cohesiveness without excessive voids or cracks.Spalling (Concrete): The development of spalls which are fragments, usually in the shape of a flake, detached from a larger mass by a blow, by the action of weather, by pres-sure, or by expansion within the larger mass.1Surface Porosity: Porosity or permeability at the concrete surface that may absorb vapors, moisture, chemicals, and coating liquids.Surface Preparation: The method or combination of meth-ods used to clean a concrete surface, remove loose and weak materials and contaminants from the surface, repair the surface, and roughen the surface to promote adhesion of a protective coating or lining system.Surface Profile (Texture): Surface contour as viewed from edge.Surface Air Voids: Cavities visible on the surface of a solid.________________________________________________________________________Section 3: Inspection Procedures Prior to Surface Preparation3.1 Concrete shall be inspected prior to surface prepara-tion to determine the condition of the concrete and to deter-mine the appropriate method or combination of methods to be used for surface preparation to meet the requirements of the coating system to be applied. Inherent variations in sur-face conditions seen in walls and ceilings versus those in floors should be considered when choosing surface prepar-ation methods and techniques. For example, walls and ceil-ings are much more likely than floors to contain surface air voids, fins, form-release agents, and honeycombs.3.2 Visual InspectionAll concrete surfaces to be prepared and coated shall be visually inspected for signs of concrete defects, physical damage, chemical damage, contamination, and excess moisture.3.3 Concrete CureAll concrete should be cured using the procedures de-scribed in ACI (1) 308.4Curing requirements include main-taining sufficient moisture and temperatures for a minimum time period. Surface preparation performed on insufficiently cured or low-strength concrete may create an excessively coarse surface profile or remove an excessive amount of concrete.3.4 Concrete DefectsConcrete defects such as honeycombs and spalling shall be repaired. The procedures described in NACE StandardRP0390,5 ICRI (2) 03730,6 or ACI 3017may be used to en-sure that the concrete surface is sound prior to surface preparation.3.5 Physical Damage3.5.1 Concrete should be tested for soundness by the qualitative methods described in NACE Publication6G1918or Paragraph A1.4.3.3.5.2 When qualitative results are indeterminate, or when a quantitative result is specified, concrete shall be tested for surface tensile strength using the meth-ods described in Paragraph A1.6.3.5.3 Concrete that has been damaged because of physical forces such as impact, abrasion, or corrosion of reinforcement shall be repaired prior to surface prep-aration if the damage would affect coating perform-ance. Repairs should be made in accordance with ACI301,7 NACE Standard RP0390,5or Paragraph A1.4.3.6 Chemical Damage3.6.1 Concrete is attacked by a variety of chemicals,as detailed in ACI 515.1R 9and PCA (3) IS001.10___________________________(1) American Concrete Institute International (ACI), 38800 International Way, Country Club Drive, Farmington Hills, MI 48331.

Examples include, but are not limited to, dirt, oil, grease, chemicals, and existing incompatible coatings.3.7.2 Contamination may be detected by methods de-scribed in NACE Publication 6G1918 and Paragraph A1.5. These methods include, but are not limited to, visual examination, water drop (contact angle) meas-urement, pH testing, petrographic examination, and various instrumental analytical methods. Core samp-ling may be required to determine the depth to which the contaminant has penetrated the concrete.3.7.3 Concrete surfaces that are contaminated or thathave existing coatings shall be tested by the method described in Paragraph A1.6.3 to determine whether the contamination or existing coating affects the ad-hesion and performance of the coating to be applied.Concrete surfaces that have existing coatings shall also be tested by the method described in Paragraph A1.6.3 to determine whether the existing coating is sufficiently bonded to the concrete.3.7.4 In extreme cases of concrete damage or degra-dation, or thorough penetration by contaminants, com-plete removal and replacement of the concrete may be required.3.8 MoistureMoisture levels in the concrete may be determined by the methods described in Paragraph 5.6.________________________________________________________________________Section 4: Surface Preparation4.1 Objectives4.1.1 The objective of surface preparation is to pro-duce a concrete surface that is suitable for application and adhesion of the specified protective coating sys-tem.4.1.2 Protrusions such as from burrs, sharp edges,fins, and concrete spatter shall be removed during sur-face preparation.4.1.3 Voids and other defects that are at or near thesurface shall be exposed during surface preparation.4.1.4 All concrete that is not sound shall be removedso that only sound concrete remains.4.1.5 Concrete damaged by exposure to chemicalsshall be removed so that only sound concrete remains.4.1.6 All contamination, form-release agents, efflor-escence, curing compounds, and existing coatings determined to be incompatible with the coating to be applied shall be removed.4.1.7 The surface preparation method, or combinationof methods, should be chosen based on the condition of the concrete and the requirements of the coating system to be applied.4.1.8 All prepared concrete surfaces shall be repairedto the level required by the coating system in the in-tended service condition.4.2 Surface Cleaning Methods4.2.1 The surface cleaning methods described in Par-agraphs 4.2.2 and 4.2.3 shall not be used as the sole surface preparation method of concrete to be coated as they do not remove laitance or contaminants or alter the surface profile of concrete. These methods shall be used as required, before and/or after the mechan-ical and chemical methods described in Paragraphs 4.3 and 4.4.4.2.2 Vacuum cleaning, air blast cleaning, and watercleaning as described in ASTM(4) D 425811 may be used to remove dirt, loose material, and/or dust from concrete.4.2.3 Detergent water cleaning and steam cleaning asdescribed in ASTM D 425811 may be used to remove oils and grease from concrete.4.3 Mechanical Surface Preparation Methods4.3.1 Dry abrasive blasting, wet abrasive blasting, vac-uum-assisted abrasive blasting, and centrifugal shot blasting, as described in ASTM D 4259,12 may be used to remove contaminants, laitance, and weak concrete,___________________________(4) ASTM International, 100 Barr Harbor Dr., West Conshohocken, PA 19428-2959. --` , , , , , -` -` , , ` , , ` , ` , , ` ---NACE No. 6/SSPC-SP 134NACE Internationalto expose subsurface voids, and to produce a sound concrete surface with adequate profile and surface porosity.4.3.2 High-pressure water cleaning or waterjettingmethods as described in NACE No. 5/SSPC-SP 12,2ASTM D 4259,12or “Recommended Practices for the Use of Manually Operated High Pressure Water JettingEquipment,”(5)13may be used to remove contaminants, laitance, and weak concrete, to expose subsurface voids, and to produce a sound concrete surface with adequate profile and surface porosity.4.3.3 Impact-tool methods may be used to remove existing coatings, laitance, and weak concrete. These methods include scarifying, planing, scabbling, and rot-ary peening, as described in ASTM D 4259.12Impact-tool methods may fracture concrete surfaces or cause microcracking and may need to be followed by one of the procedures in Paragraphs 4.3.1 or 4.3.2 to produce a sound concrete surface with adequate profile and surface porosity. The soundness of a concrete surface prepared using an impact method may be verified by one of the surface tensile strength tests described in Paragraph A1.6.4.3.4 Power-tool methods, including circular grinding, sanding, and wire brushing as described in ASTM D4259,12may be used to remove existing coatings, lait-ance, weak concrete, and protrusions in concrete. These methods may not produce the required surface profile and may require one of the procedures de-scribed in Paragraphs 4.3.1 or 4.3.2 to produce a con-crete surface with adequate profile and surface poro-sity.4.3.5 Surface preparation using the methods de-scribed in Paragraphs 4.3.1 through 4.3.4 shall be per-formed in a manner that provides a uniform, sound sur-face that is suitable for the specified protective coating system.4.4 Chemical Surface PreparationAcid etching, as described in ASTM D 426014and NACEStandard RP0892,15may be used to remove laitance and weak concrete and to provide a surface profile on horizontal concrete surfaces. This method requires complete removal of all reaction products and pH testing to ensure neutrali-zation of the acid. Acid etching is not recommended for ver-tical surfaces and areas where curing compounds or seal-ers have been used. Acid etching shall only be used where procedures for handling, containment, and disposal of the hazardous materials are in place. Acid etching with hydro-chloric acid shall not be used where corrosion of metal in the concrete (rebar or metal fibers) is likely to occur.4.5 Flame (Thermal) Cleaning and Blasting4.5.1 Flame cleaning using a propane torch or other heat source may be used to extract organic contamin-ants from a concrete surface. To remove the extracted contaminants this type of cleaning may need to be fol-lowed by the cleaning methods described in ASTM D4258.114.5.2 Flame cleaning and blasting using oxygen-acet-ylene flame blasting methods and proprietary delivery equipment may be used to remove existing coatings, contaminants, and laitance and/or create a surface pro-file on sound concrete.4.5.3 The extent of removal when employing flame methods is affected by the rate of equipment advance-ment, the flame adjustment, and the distance between the flame and the concrete surface. Surface prepara-tion using flame methods shall be performed in a man-ner that provides a uniform, sound surface that is suit-able for the specified protective coating system.4.5.4 High temperatures reduce the strength of or damage concrete; therefore, surfaces prepared using flame methods shall be tested for soundness and sur-face tensile strength. Concrete surfaces found to be unsound or low in tensile strength shall be repaired or prepared by other mechanical methods described in Paragraph 4.3.4.6 Surface CleanlinessAfter the concrete surface has been prepared to the required soundness and surface profile, surfaces may still need to be cleaned by one of the methods described in Paragraph 4.2 to remove the residue created by the surface preparation method or to remove spent media.4.7 Moisture ContentIf the moisture level in the concrete is higher than the spec-ified limit tolerable by the coating, the concrete shall be dried or allowed to dry to the level specified in the procure-ment documents before inspection and application of the coating (see Paragraph 5.6).4.8 Patching and Repairs4.8.1 Prior to proceeding with patching and repairs, the prepared concrete surface shall be inspected according to Section5. After the patching and repairs of the concrete surface are completed, the repaired areas shall be reinspected according to Section 5.4.8.2 All gouges, surface air voids, and other surface anomalies shall be repaired to a level required by the coating system as specified in the procurement docu-ments.___________________________(5)WaterJet Technology Association, 917 Locust, Suite 1100, St. Louis, MO 63101-1419.--`,,,,,-`-`,,`,,`,`,,`---//^:^^#^~^^"^~:""::$:@@:"#:$@~#~"**^::~^*^~:~^#"~^"@@\\NACE No. 6/SSPC-SP 13NACE International54.8.3 All repair materials, both cementitious and poly-meric, should be approved or recommended by the coating manufacturer as being compatible with the coating to be applied.
