                                POWER OF ATTORNEY

Know all by these presents, that the undersigned hereby constitutes and appoints
Cynthia A. Iwasaki his true and lawful attorney-in-fact to:

   (1)         execute for and on behalf of the undersigned Forms 3, 4 or 5 and
               in accordance with Section 16(a) of the Securities Exchange Act
               of 1934 and the rules thereunder;

   (2)         do and perform any and all acts for and on behalf of the
               undersigned which may be necessary or desirable to complete the
               execution of any such Form 3, 4 or 5 and the timely filing of
               such form with the United States Securities and Exchange
               Commission and any other authority; and

   (3)         take any other action of any type whatsoever in connection with
               the foregoing which, in the opinion of such attorney-in-fact, may
               be of benefit to, in the best interest of, or legally required
               by, the undersigned, it being understood that the documents
               executed by such attorney-in-fact on behalf of the undersigned
               pursuant to this Power of Attorney shall be in such form and
               shall contain such terms and conditions as such attorney-in-fact
               may approve in his discretion.

The undersigned hereby grants to each such attorney-in-fact full power and
authority to do and perform all and every act and thing whatsoever requisite,
necessary and proper to be done in the exercise of any of the rights and powers
herein granted, as fully to all intents and purposes as such attorney-in-fact
might or could do if personally present, with full power of substitution or
revocation, hereby ratifying and confirming all that such attorney-in-fact, or
his substitute or substitutes, shall lawfully do or cause to be done by virtue
of this power of attorney and the rights and powers herein granted. The
undersigned acknowledges that the foregoing attorneys-in-fact, in serving in
such capacity at the request of the undersigned, are not assuming, nor is Ameron
International Corporation a Delaware corporation, (the "Company") assuming, any
of the undersigned's responsibilities to comply with Section 16 of the
Securities Exchange Act of 1934.

This Power of Attorney shall remain in full force and effect until the
undersigned is no longer required to file Forms 3, 4, and 5 with respect to the
undersigned's holdings of and transactions in securities issued by the Company,
unless earlier revoked by the undersigned in a signed writing delivered to the
foregoing attorneys-in-fact.

IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to be
executed as of this 27 day of May 2008.

                                           Signature:     /s/ Stephen E. Johnson
                                                          ----------------------
                                                          Stephen E. Johnson
