    • Grinding. Grinding removes laitance, protrusions, surface contaminants and produces a smooth or Acid Etching. Acid etching dissolves cement and exposes fine aggregates, leaving a sandpaper-like Needle Scaling. Needle scalers pulverize concrete surfaces by the pounding action of steel rods, Abrasive Blasting. Abrasive blasting propels dry or moist abrasive in a stream of compressed air. Shotblasting. Shotblasting propels steel shot against the concrete surface by means of a wheel. Water Jetting. Water jetting removes contaminants and roughens the surface via the impact of jets Scarifying. A scarifier consists of rows of toothed washers assembled on steel rods that are Rotomilling. A rotomiller is a scarifier on steroids, so large that it must be driven, with teeth mounted Scabbling. Scabblers feature multiple pointed piston heads, pneumatically-driven, that pound the Hammering. Jackhammers and chipping hammers break up concrete when the point or chisel head Achieving Better Adhesion with Proper Surface Preparationpreparation is to increase the surface energy of the substrate to be bonded. Higher surface energy substrates allow for easier bonding as compared to lower surface energy substrates because of the wettability factor. Hence, good surface preparation is vital in order to provide easily wettable and cohesively strong surfaces with improved bond

      Mar 19, 2021 · Surface Cleanliness As discussed in Topic 2 of this series, Preparation of Precast Concrete for Painting, surface preparation may include one or more of the following. The methods of cleaning are described in the ASTM standards listed below as well as International Concrete Repair Institute (ICRI) ICRI Guideline 310.2, Selecting and Specifying Concrete Surface Preparation for SSPC Surface Preparation Standards American Galvanizers May 01, 2014 · The preparation for painting and powder coating over a hot-dip galvanized coating, as well as the repair of damaged and uncoated areas, use SSPC-SP2 as a standard surface preparation procedure. The specifications for preparing hot-dip galvanized steel for paint and powder coating ASTM D6386 and D7803 respectively list hand tool cleaning as an acceptable method for smoothing the surface SURFACE PREPARATION SPECIFICATIONSThis Surface Preparation Commentary (SP COM) is in-tended to be an aid in selecting the proper surface preparation method, materials, and speci cation for steel, other metals, and concrete. A compilation of standards, guides, and speci- cations related to concrete is available as SSPC publication #04-03 Surface Preparation and Coating


      Surface Preparation and Cleaning of Steel and Other Hard Materials by High- and Ultra High- Pressure Water Jetting Prior to Recoating This standard requires water jetting at high- or ultra high-pressure to prepare a surface for recoating using pressure above 10,000 psi. Surface Preparation - Sherwin-Williams Protective & Marine International Concrete Repair Institute (icri) No. 03732 Guideline for Selecting and Specifying Concrete Surface Preparation for Sealers, Coatings, and Polymer Overlays This standard summarizes the capabilities, operating requirements, and limitations of the various methods used to prepare concrete surfaces for the application of protective sealers, coatings, and polymer overlays. Surface Preparation - Sherwin-WilliamsTo ensure adhesion of the coating to the substrate and prolong the service life of the coating system, select and implement the proper surface preparation. The method of surface preparation depends on the substrate, the environment, and the expected life of the coating system. Economics and surface contamination (including its effect on the substrate) will also influence the selection of surface preparation

      Surface Preparation for Coating - NPL

      Surface preparation is the essential first stage treatment of a substrate before the application of any coating. The performance of a coating is significantly influenced by its ability to adhere properly to the substrate material. It is generally well established that correct surfaceSurface preparation - SteelConstructionfoClick to view0:40Surface preparation is the essential first stage treatment of a steel substrate before the application of any coating, and is generally accepted as being the most important factor affecting the total success of a corrosion protection system.
