                  [Letterhead of Calfee, Halter & Griswold LLP]

RPM International Inc.
2628 Pearl Road
P.O. Box 777
Medina, Ohio 44258

         We are familiar with the proceedings taken and proposed to be taken by
RPM International Inc., a Delaware corporation (the "Company"), with respect to
shares of Common Stock, par value $0.01 per share (the "Shares"), of the Company
to be offered and sold from time to time pursuant to the Company's 1996 Key
Employees Stock Option Plan, as amended (the "Plan"), which Shares were
registered under the Securities Act of 1933, as amended (the "Securities Act"),
by RPM, Inc., an Ohio corporation. In connection with a merger transaction for
the purpose of changing RPM, Inc.'s state of incorporation to Delaware, the
Company became the successor issuer to RPM, Inc. under the Securities Exchange
Act of 1934, as amended, and pursuant to Rule 414 under the Securities Act, has
expressly adopted the prior registration statements filed with the Securities
and Exchange Commission (the "Commission") to register the Shares. As counsel
for the Company, we have assisted in preparing a Post-Effective Amendment to the
Registration Statements on Form S-8 (the "Registration Statement") to be filed
by the Company with the Securities and Exchange Commission in connection with
the registration of the Shares under the Securities Act.

         In this connection, we have examined such documents, records and
matters of law as we have deemed necessary or advisable to render the opinion
contained herein. Based upon our examination and inquiries, we are of the
opinion that the Shares are duly authorized and, when offered and sold pursuant
to the terms and conditions of the Plan, will be validly issued, fully paid and
nonassessable.

         Our opinion is limited solely to the laws of the State of Delaware.

         We consent to the filing of this opinion as Exhibit 5.1 to the
Registration Statement. We do not admit that we are in the category of persons
whose consent is required under Section 7 of the Securities Act.


                                          Very truly yours,

                                          /s/ Calfee, Halter & Griswold LLP

                                          CALFEE, HALTER & GRISWOLD LLP
