                             RULE 12b-25 (b) AND (c)

         If the subject report could not be filed without unreasonable effort or
expense and the registrant seeks relief pursuant to Rule 12b-25(b), the
following should be completed. (Check box if appropriate.)

[X]           (a)    The reasons described in reasonable detail in Part III of
                     this form could not be eliminated without unreasonable
                     effort or expense;

                     report on Form 10-K, 20-F, 11-K or Form N-SAR, or portion

                     day following the prescribed due date; or the subject
                     quarterly report or transition report on Form 10-Q, or
                     portion thereof, will be filed on or before the fifth

                                    PART III

                                    NARRATIVE

         State below in reasonable detail the reasons why Form 10-K, 20-F, 11-K,
10-Q, N-SAR, or the transition report portion thereof, could not be filed within
the prescribed time period. (Attach extra sheets if needed.)

         Additional time is required in order for the RPM International Inc.
Union 401(k) Retirement Savings Trust and Plan, as amended (the "Plan"), to file
its Annual Report on Form 11-K. As a result of a change in the Plan, which
required for the first time the filing of a Form 11-K, and due to administrative
delays in providing the required information to the Plan's independent
accountants, the Plan is unable to file the audited financial statements
required by the Form 11-K within the prescribed time period.

                                     PART IV

              Janeen Kastner                         (330)                            273-5090
----------------------------------------------------------------------------------------------------------
                   (Name)                         (Area code)                   (Telephone Number)


         (2) Have all other periodic reports required under Section 13 or 15(d)
of the Securities Exchange Act of 1934 or Section 30 of the Investment Company
Act of 1940 during the preceding 12 months or for such shorter period that the
registrant was required to file such report(s) been filed? If the answer is no,
identify report(s).
                                                             [X]  Yes   [ ]  No



                                       2


         (3) Is it anticipated that any significant change in results of
operations from the corresponding period for the last fiscal year will be
reflected by the earnings statements to be included in the subject report or
portion thereof?
                                                             [ ]  Yes   [X]  No

         If so: attach an explanation of the anticipated change, both
narratively and quantitatively, and, if appropriate, state the reasons why a
reasonable estimate of the results cannot be made.
