PART I - REGISTRANT INFORMATION

                           DAYTON SUPERIOR CORPORATION
                             Full Name of Registrant

                    7777 WASHINGTON VILLAGE DRIVE, SUITE 130
                      Address of principal executive office

                               DAYTON, OHIO 45459
                            City, State and Zip Code





PART II - RULES 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. [ X ]

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

           (b) The subject annual report, semi-annual report, transition report
     on Form 10-K, Form 20-F, Form 11-K, Form N-SAR or Form N-CSR, or portion
     thereof, will be filed on or before the fifteenth calendar 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 calendar day following the prescribed due date; and

           (c) The accountant's statement or other exhibit required by Rule
12b-25(c) has been attached if applicable.

PART III - NARRATIVE

         State below in reasonable detail the reasons why Forms 10-K, 20-F,
11-K, 10-Q, N-SAR or the transition report or portion thereof, could not be
filed within the prescribed time period.

During the second quarter 2003 closing process, the Company determined that its
income statement classification did not appropriately reflect EITF 00-10
"Accounting for Shipping and Handling Fees and Costs". EITF 00-10 requires
that all shipping and handling costs billed to customers be recorded as sales
and the actual costs incurred be recorded as a component of cost of sales. Prior
to the second quarter of 2003, the Company netted its freight costs against
freight revenue. As a result of adopting EITF 00-10, the Company's net sales and
cost of sales will both increase by an equal amount to reflect the inclusion of
shipping revenues and costs, but there will be no effect on the Company's gross
profit, operating income, net income (loss), or cash flows. Extra time is
required to restate prior quarters for this classification change.

PART IV - OTHER INFORMATION

         (1) Name and telephone number of person to contact in regard to this
notification:

                          (937) 428-6360 EXTENSION 324


         (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 reports) been filed?
     If answer is no, identify reports.

                  [X]  Yes                                      [ ] No

         (3) Is its 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
