Full title and description
Standard Practice for Surface Preparation of Concrete for Application of Chemical‑Resistant Resin Monolithic Surfacings — ASTM C811‑98 (recorded/reapproved editions noted through 2008). The practice gives recommendations for preparing concrete to receive filled, resin‑based monolithic surfacings (toppings 60 mils / 1.5 mm or greater) including surface cleaning, profiling, and tests to ensure a sound bonding substrate.
Abstract
This practice describes methods and acceptance criteria for preparing concrete so that resinous monolithic surfacings (fillers, resins and hardeners) will bond continuously to the concrete substrate. It addresses surface cleanliness, desired surface profile (roughened appearance similar to coarse sandpaper), common preparation methods (abrasive blasting, scarifying, acid etching), and pre‑application checks such as moisture, temperature and surface tensile bond strength testing.

Scope
This practice provides recommendations for preparing concrete to receive resinous monolithic surfacings (toppings ≥ 60 mils / 1.5 mm) that cure in place and are continuously bonded to the concrete. It applies to filled resin systems (see relation to Specification C722) and describes acceptable surface profile, cleaning and neutralization of contaminated concrete, and common preparation techniques while noting that it does not override specific manufacturer instructions.
Key topics and requirements
- Definition of "monolithic surfacings" (toppings ≥ 60 mils / 1.5 mm) and their intended properties.
- Desirable substrate condition: clean, sound concrete with a roughened profile (similar to coarse sandpaper) for improved adhesion.
- Acceptable preparation methods: abrasive blasting, scarifying, acid etching and other mechanical/chemical techniques to achieve profile and cleanliness.
- Requirement to clean and neutralize contaminated concrete prior to application.
- Pre‑application checks and tests: moisture and temperature considerations and surface tensile bond strength tests.
- Guidance that the practice is intended to be used with filled resin systems (see ASTM C722) and does not supersede manufacturer application instructions.
Typical use and users
Used by architects and specification writers, flooring and coatings contractors, concrete repair and restoration professionals, quality/control inspectors, and manufacturers of resinous flooring systems to define acceptable substrate preparation prior to applying chemical‑resistant monolithic surfacings. It is also used by testing laboratories and facility maintenance teams when validating surface readiness.
Related standards
Commonly referenced standards and documents include ASTM C722 (Specification for Chemical‑Resistant Monolithic Floor Surfacings), ASTM C904 (Terminology Relating to Chemical‑Resistant Nonmetallic Materials), and various test methods for bond strength, moisture measurement and abrasion; many of these are listed alongside C811 in resin‑flooring literature and specifications.

FAQ
Q: What is this standard?
A: ASTM C811‑98 is a short practice that provides recommendations for preparing concrete surfaces to receive chemical‑resistant, filled resin monolithic surfacings (toppings ≥ 60 mils).
Q: What does it cover?
A: It covers acceptable substrate condition and profile, cleaning and neutralization of contaminated concrete, commonly used preparation methods (e.g., abrasive blasting, scarifying, acid etching), and required pre‑application checks such as moisture and surface bond strength tests. It explicitly notes that it does not replace manufacturer application instructions.
Q: Who typically uses it?
A: Architects and specifiers, flooring/coatings contractors, manufacturers of resinous surfacings, testing laboratories, and facility maintenance/quality personnel.
Q: Is it current or superseded?
A: ASTM C811‑98 is withdrawn (listed as withdrawn in 2012). ASTM indicates the document was withdrawn and no direct replacement is shown in the ASTM record. Users should reference current, active ASTM specifications (for example, ASTM C722 and other active test methods/specifications) and manufacturer guidance for current practice.
