(Concrete) Caveat Emptor! Preparing Cementitious Mortars to Support High-Performance Lining Systems

Product Number: 34-COAT_DEC21

Author: Vaughn O’Dea

Publication Date: 2021

$20.00

Cementitious repair mortars are commonly used to rehabilitate deteriorated wastewater concrete infrastructure prior to the application of high-performance lining systems. These repair mortars occasionally receive a broom finish creating a “profiled” surface prior to the application of a trowel- or spray-applied protective lining system. Other recommendations require that that the cementitious mortars receive a blasted surface to impart a mechanical profile prior to topcoating with a similar lining system. In the following paper the author summarize the results of an investigation to quantitatively assess adhesion of a protective lining when applied to a broom finish surface verses a blasted surface.

A Study on Improving Surface Preparation Productivity Using Rectangular Blasting Nozzle

Product Number: 41216-980-SG

Author: ChangHun Lee, ByeongHun Do, WonJun Yun, HanJin Bae

Publication Date: 2016

$20.00

The purpose of surface preparation is to get a required adhesion between steel and the coated film. Adhesion is a significant factor for the suitability and life of protective coatings in corrosive surroundings. In the shipbuilding industry, air blasting with round blasting nozzles is common practice for achieving the productivity and proper surface profile. Generally, the round blasting nozzle cannot evenly spread the abrasive material on a steel surface compared with a rectangular nozzle.

Effects of Blasting Methods on the Performance of Organic Coatings

Product Number: 41206-267-SG

Author: Andreas W. Momber

Publication Date: 2006

$20.00

The effects of three blasting methods utilised for surface preparation upon the behavior of five organic coating systems are investigated. The blasting methods include dry blast cleaning, UHP and UHPAB. It is shown that pull-off strength, pull-off failure mode, and delamination are significantly affected by the surface preparation method.

Minimizing Health, Safety, and Environmental Challenges Associated with Traditional Blasting by Using Vapor Abrasive Blasting

Product Number: 41215-889-SG

Author: Bill Eliason

Publication Date: 2015

$20.00

Industries such as oil and gas, marine, cleaning and protective coatings face many changes and challenges from environmental, safety and other regulatory agencies. Most of these changes have to do with containment regulations and minimizing dust in open air blast environments. With these regulations now in place, contractors are looking for alternatives to traditional dry blasting.

Optimized Surface Preparation Method for Maintenance and Repair Coating

Product Number: MECC23-19877-SG

Author: Sangki Chi; Mohammed Alrudayni; Mana Al-Mansour

Publication Date: 2023

$20.00

To achieve adequate protection of assets, use of a protective coating is one of predominant methods used in the oil and gas industry. There are several factors contribute in the coating service life, including surface preparation, coating application, coating material and environmental conditions. It is well known in the coating industry that 70% of the coating failures are attributed to improper surface preparation.

Performance Test Results of New Artificial Non-Metallic Abrasive

Product Number: MPWT19-14265

Author: Sangki Chi, Ebad ul Haque, Shaj K. Manjalivalapil

Publication Date: 2019

$0.00

Abrasive material forms a major component for surface preparation in coating applications. Since blastin
g method developed in 1890s, abrasive materials and its application methods also significantly improve
d to enhance blasting efficiency. In general, steel grit and shot ball are being used predominantly as me
tallic abrasives. Garnet and coal slag are used as non-metallic abrasives. Each abrasive is selected and
applied in accordance with the work location and substrate material of structures to be coated. In this st
udy, we have evaluated a new artificial non-metallic abrasive (ferrochrome slag) which is a by-product fr
om ferrochrome production process for stainless steel. This evaluation also included the checking of sur
face cleanliness performance and coating quality based on international test methods and field trials. Fo
r verifying the cleanliness quality, various tests were conducted as per international standards (ISO 850
1-8503). Sea water immersion test (ISO 2812-2) and cyclic test (ISO 12944-9) were carried out to check
coating performance after blasting. The field test results indicates that all inspection and quality criteria o
f surface preparation were met as per international standards. Furthermore, coating performance test re
sults also showed this abrasive does not have any adverse effect on coating properties.

Put Down that Blast Nozzle! How to select and optimize wet or vapor abrasive blasting equipment

Product Number: 51218-114-SG

Author: Wade Hannon

Publication Date: 2018

$20.00

Vapor/wet blasting is proving to be an attractive method for surface preparation of steel, concrete, wood and other substrates. By using just enough media and water to suppress dust and achieve the desired production rates, Vapor Abrasive® blasting avoids the dusty side effects of dry blasting and the messy runoff generated by wet blasting. To achieve optimal results in Vapor Abrasive® blasting, the system must be properly matched for the job at hand.
