6.0 Procedure

规程

6.1Inspection 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。

6.2 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。

6.3Removal 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
