Increase the adhesive reliability of mortar and similar materials! Coarse finishing method using a high-pressure washer.
"Concrete surface roughening" refers to a treatment method for concrete surfaces using high-pressure water washing, aimed at removing contaminants and weak layers from the substrate concrete of ceramic tiles or mortar coatings, and creating effective roughness for adhesion. The high-pressure water washing roughening method is performed before applying mortar or tiles (in the case of direct bonding) to enhance the adhesion reliability between concrete and mortar by creating effective roughness for adhesion and removing dirt and weak layers. [Features] - Supervised by the Ministry of Land, Infrastructure, Transport and Tourism, Bureau of Construction [FY 2001 version of Common Specifications for Construction Work] Corresponds to Tile Work 11.3.3 (a) (ii) and 15.2.4 (c) - Adopted in the "10-Year Defect Warranty System for Tile Exterior Wall Construction" for "Substrate Treatment" For more details, please contact us.

basic information
【Surface Preparation Method Using High-Pressure Water Washing】 ○ Before applying mortar or tiles (in the case of direct application), the concrete surface is high-pressure washed to create effective roughness for mortar adhesion. ○ By removing dirt and weak layers, the adhesion reliability between concrete and mortar is enhanced. ○ The Director of the Bureau of Construction of the Ministry of Construction has issued a notification to regional construction bureaus regarding "the method of re-tiling exterior wall tiles in maintenance work," which serves as the specification for this method. ○ The surface preparation using high-pressure water washing is to be conducted at a water pressure of 50 MPa for approximately 2.5 minutes per square meter. ● For more details, please contact us.
