(2) Most restrictive VOC limit.
If a coating is recommended for use in more than one of the specialty coating categories listed in the table in paragraph (A) of this rule, the most restrictive (or lowest) VOC content limit applies. This requirement applies to: usage recommendations that appear anywhere on the coating container, anywhere on any label or sticker affixed to the container, or in any sales, advertising, or technical literature supplied by a manufacturer or anyone acting on their behalf.

A coating manufactured prior to the effective date specified for that coating in the table in paragraph (A) of this rule, and that complied with the standards in effect at the time the coating was manufactured, may be sold, supplied, or offered for sale for up to three years after the specified effective date. In addition, a coating manufactured before the effective date specified for that coating in the table in paragraph (A) of this rule may be applied at any time, both before and after the specified effective date, so long as the coating complied with the standards in effect at the time the coating was manufactured. This paragraph does not apply to any coating that does not display the date or date code required by rule 3745-113-04 of the Administrative Code.
(B) Painting practices.
All AIM coating containers used to apply the contents therein to a surface directly from the container by pouring, siphoning, brushing, rolling, padding, ragging, or other means, shall be closed when not in use. These AIM coatings containers include, but are not limited to, drums, buckets, cans, pails, trays, or other application containers. Containers of any VOC-containing materials used for thinning and cleanup shall also be closed when not in use.
(C) Thinning.
No person who applies or solicits the application of any AIM coating shall apply a coating that is thinned to exceed the applicable VOC limit specified in the table of paragraph (A)(3) of this rule.
(D) Rust preventive coatings.
No person shall apply or solicit the application of any rust preventive coating for industrial use, manufactured before January 1, 2024, unless such a rust preventive coating complies with the industrial maintenance coating VOC limit specified in the table in paragraph (A) of this rule. No person shall sell or offer for sale any rust preventive coating for application to any nonmetallic substrate, nor shall any person apply a rust preventive coating to any nonmetallic substrate.
(E) Coatings not listed in the table of paragraph (A) of this rule.
For any coating that does not meet any of the definitions for the specialty coatings categories listed in the table of paragraph (A) of this rule, the VOC content limit is determined by classifying the coating as a flat coating, non-flat coating, or non-flat-high-gloss coating as defined in rule 3745-113-01 of the Administrative Code and the corresponding flat or non-flat or non-flat-high-gloss coating limit in the table in paragraph (A) of this rule applies.
(F) New categories.
Prior to January 1, 2024, any coating that meets the definition in rule 3745-113-01 of the Administrative Code for a coating category listed in the table in paragraph (A) of this rule, and complies with the applicable VOC limit in the table in paragraph (A) of this rule and reporting requirements, is considered in compliance with this rule.
