Ceveat Emptor! Preparing Cementitious Mortars for Support HighPerformance Lining Systems: Broom Finish or Blasted Surface?
Available for download

Cementitious repair mortars are commonly used to rehabilitate deteriorated wastewater concrete infrastructure prior to the application of high-performance lining systems. Commonly such repair mortars receive a broom finish creating a “profiled” surface prior to the application of a spray applied protective lining system. Other recommendations require that that the cementitious mortars receive a blasted (mechanically profiled) surface to impart a mechanical profile prior to top coating with a similar lining system. In the following paper the authors 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.

In the application of coating / lining systems, applied film thickness is an important aspect in the execution of the project. Specifications call for a required minimum film build, not to verify material use, but because it relates to the overall performance of the project. Knowing the applied film thickness of the coating / lining system as the job proceeds also helps determine if one has obtained sufficient material to successfully complete the application work as specified.

The mechanical properties of polymeric coatings are often overlooked because researchers are not aware of how modern instrumentation can now aid them in understanding how a particular product may survive in service conditions. In many applications the two main considerations are aesthetics and durability, both of which can be directly related to the mechanical properties of the base material.
