Procedure 规程

6.1 Inspection of the Concrete Substrate 混凝土基层检测

It is to determine the concrete ' s general condition, soundness,

presence of contaminants, presence of moisture vapor emissions and the best methods to

use in preparation of the surface to meet the requirements of the client or the manufacturer ' s recommendation.

对混凝土通过现场堪察及基层检测，掌握混凝土的总体情况、表面坚实 度、污染情况及潮气含量，从而决定表面处理最佳方式，以达到客户和 材料生产商的要求。

Pre-clean all surfaces by brooming and if necessary accomplished by scrubbing with heavy

duty cleaner / degreaser or low pressure water cleaning (less than 5,000 psi) or chemical

washing to remove oils, grease, wax, fatty acids and other contaminations. 先用扫帚清洁地

表，必要时使用深度清洁剂去除地表污渍，或用低压水 冲洗(不超过 5,000 psi )，也可以使

用化学溶液去除油污，油脂，表 腊，脂肪酸或其它污染。

6.3 Removal of Surface Laitance and Creation of Surface Profile 去除水泥翻沫，提供粗糙度

Removal of surface laitance and /or curing compound and creation of surface profile can be

accomplished by a number of methods each utilizing a selection of tools, equipment and

materials to accomplish the intended purpose, (See table below). Selection is dependent

upon the type of surface to be prepared and the type of system to be installed. In addition,

floors, walls, ceilings, trenches, tanks and sumps each have their own particular

requirements. The type and thickness of the selected coating system also plays an important role in the selection process. Regardless of the method selected or tools employed, we must provide a surface that will accept the application of polymer-based products and allow the

mechanical bond of the polymer securely to the concrete.

去除水泥翻沫及养护剂、脱模剂需使用手动工具或设备来完成。根据待 涂装地坪的表面以及不同的涂装系统，选择不同的作业工具和作业方法 （见下表）。此外，地坪、墙壁、天花板、地沟、水槽和水罐对工具使用 会有不同的要求。而且工具选择与所选用的涂装厚度和类型也有关系。 无论选择哪种类型的工具，我们必需提供一个适合聚合树脂材料涂装的 表面，且保证涂装材料与地坪有良好的机械附着力。

The follow ing table provides a guide for the degree of surface profile required for the coating or overlay to be applied and the preparati on methods used to gen erate each profile to the specified sta ndard.
