This document provides a summary of ICRI Technical Guideline No. 310.2-1997, which provides guidance on selecting and specifying methods for preparing concrete surfaces prior to applying sealers, coatings, or polymer overlays. The guideline is intended for use by designers, specifiers, contractors, and manufacturers. It includes a selection method to determine the appropriate surface preparation for a project based on objectives and requirements, a chart matching preparation methods to coating types, and physical replicas of prepared surfaces to use as visual standards. The overall benefits highlighted are enabling the specification of exact surface preparations and verification that the proper preparation was achieved.

Surface Preparation
Who is this guideline for?
• Designers
– Provides a method to determine project objectives and requirements
• Specifiers
– Provides selector chart of methods to achieve each coating type
– Provides replicas of typical surfaces for on-site standards
• Contractors
– Provides information on the results of various methods of preparation
– Provides on-site visual to verify surface preparation has been completed
• Manufacturers
– Provides a visual standard for desired surface preparation for a
particular product.
Sealers, Coatings & Polymer Overlays

4. What is covered?
• A workbook designed to organize and prioritize
information needed for good selection decisions.
• A chart which identifies methods capable of production the
profile typically recommended for each coating type.
• Presents capabilities, limitations, operating requirements,
environmental factors, and safety consideration for each
method of surface preparation.
• Surface Profile Chips – Replicas of typical surfaces
produced by one or more of the methods providing a
visual standard for purposes of specification, execution
and verification.

5. Benefits of Using This Guide…
• Specifiers and manufactures can specify an
exact surface desired for a particular repair and
a method to confirm it has been achieved.
• Provides designers with a selection method
which provides optimum balance of
performance, risk and cost factors.
• Information for all the available methods
provided in one location.
