                                AMENDMENT NO. 27
                                 TO SCHEDULE 13D

            This amended statement relates to the Common Stock, $1.00 par value
per share (the "Shares"), of Katy Industries, Inc., a Delaware corporation (the
"Issuer"). This amended statement is being filed in accordance with Rule
101(a)(2)(i) of Regulation S-T promulgated by the Securities and Exchange
Commission in connection with the Commission's Electronic Data Gathering,
Analysis and Retrieval System ("EDGAR").

            This amended statement on Schedule 13D is jointly filed by
Wallace E. Carroll, Jr.; Amelia M. Carroll; The Wallace E. Carroll Trust U/A
Dated 7/1/57 F/B/O Wallace E. Carroll, Jr. and his descendants; The Wallace
E. and Lelia H. Carroll Trust U/A Dated 5/1/58 F/B/O Wallace E. Carroll, Jr.
and his descendants (the "58 Trust"); The Wallace E. Carroll Trust U/A Dated
1/20/61 F/B/O Wallace E. Carroll, Jr. and his descendants; The Lelia H.
Carroll Trust U/A Dated 7/12/62 F/B/O Wallace E. Carroll, Jr. and his
descendants; CRL, Inc., a Delaware corporation ("CRL"); The Wallace
Foundation; and the Subtrusts under The Wallace E. Carroll Trust U/A dated
12/20/79 F/B/O the descendants of Wallace E. Carroll, Jr. (collectively, the
"Reporting Persons") pursuant to a Schedule 13D Joint Filing Agreement dated
as of June 29, 2001 previously filed as Exhibit D to Amendment No. 26 to this
statement.

Item 5.     Interest in Securities of the Issuer.

      Item 5 is hereby amended as follows:

            As previously reported on this amended statement, on May 24, 2001,
CRL entered into amendments, effective as of February 28, 2001, to its Amended
and Restated Revolving Credit Agreement dated as of December 31, 1993, as
amended, which was previously filed as Exhibit CC to Amendment No. 14 to this
statement, and its Pledge Agreement dated as of December 31, 1995, as amended,
which was previously filed as Exhibit A to Amendment No. 24 to this statement
(collectively, the "Agreements"), each with The Northern Trust Company
("Northern Trust"), pursuant to which CRL pledged to Northern Trust all of the
2,073,436 Shares it owns to secure the prompt and complete payment and
performance when due of all of CRL's obligations under the Agreements. In
connection therewith, the 58 Trust entered into a Pledge Agreement (the "Pledge
Agreement"), dated as of Feburary 28, 2001 and in favor of Northern Trust,
pursuant to which the 58 Trust pledged to Northern Trust a securities account
with Northern Trust in the name of the 58 Trust (the "Account") to secure the
full and prompt payment and performance of all of CRL's obligations under the
Agreements and the 58 Trust's obligations under the Pledge Agreement.

            On July 30, 2001, CRL sold an account receivable (the "Receivable")
to the 58 Trust for a purchase price of $2,000,000. CRL used the funds received
from such sale to make a payment to Northern Trust on amounts owed under the
Agreements. The 58 Trust withdrew funds from the Account to pay the purchase
price to CRL for the Receivable. In exchange for Northern Trust releasing the
funds for such payment from the pledge of the Account, the 58 Trust pledged to
Northern Trust all of the 603,000 Shares the 58 Trust owns as substitute
collateral under the Pledge Agreement.

            The description of the Agreements and the Pledge Agreement are
qualified in their entirety by the provisions of such agreements attached to
this amended statement as exhibits or previously filed as exhibits to prior
amendments to this statement.

            respect to Securities of the Issuer.

      Item 6 is hereby amended as follows:

            The description of the Pledge Agreement set forth in Item 5 above is
incorporated herein by reference in its entirety.

This Pledge Agreement (as modified from time to time, this "AGREEMENT") has been

is continuing as of such date; and (ii) Debtor's representations and warranties

the Collateral, and do or cause to be done, execute (or cause to be executed)
such other documents, and take (or cause to be taken) such other actions as
Secured Party may deem reasonably necessary or appropriate in connection
therewith.

6. APPOINTMENT OF SUB-AGENTS; REGISTRATION IN NOMINEE NAME.

       (a) The Secured Party shall have the right to appoint one or more

given by Debtor or any other person to any such issuer or any such depository,

                                     Page 4


                              Page 18 of 26 Pages


FOREGOING, UNTIL SECURED PARTY NOTIFIES DEBTOR TO THE CONTRARY OR AN EVENT OF
DEFAULT (AS DEFINED BELOW) OCCURS, DEBTOR MAY CONTINUE TO RECEIVE REGULAR CASH

SUCH DIVIDENDS AND INTEREST PAYMENTS SHALL NOT BE DEEMED COLLATERAL UNDER THIS
AGREEMENT.

       (b) Defend the Collateral against the claims and demands of all persons
other than Secured Party and promptly pay all taxes, assessments, and charges
upon the Collateral which are not being contested in good faith by Debtor and
for which adequate reserves are being maintained, and not sign (or permit to be
signed) any documents creating or perfecting a lien upon or a security interest
in any of the Collateral except in favor of Secured Party, or otherwise create,

                              Page 19 of 26 Pages


10. DEFAULT REMEDIES.

       (a) Notwithstanding any provision of any document or instrument
evidencing or relating to any Liability, upon the occurrence and during the
continuance of any Event of Default specified in Section 8.1 of the Credit
Agreement, Secured Party at its option may declare the Liabilities immediately
due and payable without notice or demand of any kind (provided that, upon the
occurrence of any Event of Default specified in Section 8.1 (g) of the Credit
Agreement, the Liabilities shall be immediately and automatically due and
payable without action of any kind on the part of Secured Party). Upon the
occurrence and during the continuance of any Event of Default, Secured Party may
exercise any rights and remedies under this Agreement, the Credit Agreement, any
related document or instrument (including without limitation any pertaining to
Collateral), and at law or in equity.

       (b) If any Event of Default shall have occurred and be continuing, then,
in addition to having the right to exercise any rights and remedies of a secured
party upon default under the Uniform Commercial Code in effect in the State
where the main banking office of Secured Party or any Collateral is located,
Secured Party may, in its sole discretion:

       (i) without being required to give any prior notice to Debtor apply the
cash (if any) then held by it hereunder, toward the Liabilities in such order as
Secured Party shall determine in its sole discretion; and

       (ii) if there shall be no such cash or the cash so applied shall be
insufficient to pay all obligations in full, sell the Collateral, or any part
thereof, at any public or private sale, for cash, upon credit or for future
delivery, as Secured Party shall reasonably deem appropriate. The Secured Party
shall be authorized at any such sale (to the extent it deems it advisable to do
so, in its sole discretion) to restrict the prospective bidders or purchasers to
persons who will represent and agree that they are purchasing the Collateral
then being sold for their own account for investment and not with a view to the
distribution or resale thereof, and upon consummation of any such sale Secured
Party shall have the right to assign, transfer and deliver to the purchaser(s)
thereof the Collateral so sold. Each such purchaser at any such sale shall hold
the property sold absolutely free from any claim or right on the part of Debtor,
and Debtor hereby waives (to the extent permitted by law) all rights of
redemption, stay and/or appraisal which it now has or may at any time in the
future have under any rule of law or statute now existing or hereafter enacted.
To the extent that notice of sale shall be required to be given by law, Secured
Party shall give Debtor at least ten days' written notice of Secured Party's
intention to make any such public or private sale or sales. Secured Party shall
not be obligated to make any sale of Collateral if it shall determine not to do
so, regardless of the fact that notice of sale of Collateral may have been
given. Secured Party may, without notice or publication, adjourn any public or
private sale or cause the same to be adjourned from time to time by announcement
at the time and place fixed for sale, and such sale may, without further notice,
be made at the time and place to which the same was so adjourned. In case sale
of all or any part of the Collateral is made on credit or for future delivery,
the Collateral so sold may be retained by Secured Party until the sale price is
paid by the purchaser thereof, but Secured Party shall not incur any liability
in case any such purchaser shall fail to take up and pay for the Collateral so
sold; in the case of any such failure, such Collateral

                                     Page 6


                              Page 20 of 26 Pages



may be sold again upon like notice. As an alternative to exercising the power of
sale herein conferred upon it, Secured Party may proceed by a suit at law or in
equity to foreclose this Agreement and to sell the Collateral, or any portion
thereof, pursuant to a judgment or decree of a court of competent jurisdiction.
The proceeds of sale of Collateral sold pursuant hereto shall be applied by
Secured Party in such order as it shall determine.

       (c) Secured Party may, by written notice to Debtor, at any time and from
time to time, waive any Event of Default or "Unmatured Event of Default" (as
defined below), which shall be for such period and subject to such conditions as
shall be specified in any such notice. In the case of any such waiver, Secured
Party and Debtor shall be restored to their former position and rights
hereunder, and any Event of Default or Unmatured Event of Default so waived
shall be deemed to be cured and not continuing; but no such waiver shall extend
to or impair any subsequent or other Event of Default or Unmatured Event of
Default. No failure to exercise, and no delay in exercising, on the part of
Secured Party of any right, power or privilege hereunder shall preclude any
other or further exercise thereof or the exercise of any other right, power or
privilege. The rights and remedies of Secured Party herein provided are
cumulative and not exclusive of any rights or remedies provided by law.
"Unmatured Event of Default" means any event or condition which would become an
Event of Default with notice or the passage of time or both.

11. POWERS OF SECURED PARTY. Secured Party may, from time to time, at its option
(but shall have no duty to):

(a) perform any agreement of Debtor hereunder that Debtor shall have failed to
perform;

(b) take any other action which Secured Party deems reasonably necessary or
desirable for the preservation of the Collateral or Secured Party's interest
therein and the carrying out of this Agreement, including without limiting the
generality of the foregoing: (i) any action to collect or realize upon the
Collateral; (ii) the discharge of taxes, liens, security interests or other
encumbrances at any time levied or placed on the Collateral; (iii) the discharge
or keeping current of any obligation of Debtor having effect on the Collateral;
or (iv) subject to SECTION 8(A) hereof, receiving, endorsing and collecting all
checks and other orders for the payment of money made payable to Debtor
representing any dividend, interest payment or other distribution payable or
distributable in respect of the Collateral or any part thereof, and to give full
discharge for the same;

(c) file, or cause to be filed, photocopies or carbon copies of any financing
statement respecting any right of Secured Party in the Collateral, and any such
photocopy or carbon copy of the signature of Debtor on such photocopy or carbon
copy shall be deemed an original for purposes of such filing. Debtor hereby
authorizes Secured Party to sign financing statements on Debtor's behalf to be
filed in all jurisdictions in which such authorization is permitted, and Secured
Party shall endeavor to provide Debtor a copy of any such filing; and

(d) (without limiting any other provision hereof) in its discretion request that
any uncertificated securities or deposits constituting Collateral hereunder be
delivered to it in definitive form. Upon receipt of such request from Secured
Party, Debtor will immediately take

                                     Page 7


                              Page 21 of 26 Pages



all reasonable steps (including, without limitation, the payment by Debtor of
all reasonable costs and expenses of issuance and transfer) required to cause
such uncertificated securities or deposits to be issued and delivered in
definitive form to Secured Party, together with any and all documents (executed
in blank) required to erect the transfer of definitive securities or deposits in
definitive form to Secured Party. The parties expressly agree that such
securities or deposits when issued in definitive form shall continue to
constitute Collateral for purposes of this Agreement.

Debtor hereby appoints Secured Party as Debtor's attorney-in-fact, which
appointment is and shall be deemed to be irrevocable and coupled with an
interest, for purposes of performing acts and signing and delivering any
agreement, document, or instrument, on behalf of Debtor in accordance with this
SECTION 11. Debtor immediately will reimburse Secured Party for all reasonable
expenses so incurred by Secured Party, together with interest thereon at 3% in
addition to the Prime Rate.

12. FURTHER ASSURANCES. Debtor agrees to do (or cause to be done) such further
acts and things, and to execute and deliver (or cause to be executed and
delivered) such additional conveyances, assignments, agreements, and
instruments, as Secured Party may at any time reasonably request in connection
with the administration or enforcement of this Agreement or related to the
Collateral or any part thereof or in order better to assure and confirm unto
Secured Party its rights, powers and remedies hereunder.

13.   ADDITIONAL   PROVISIONS  REGARDING  SECURITIES  ACCOUNT.  The  following
additional  provisions  pertaining  to the  Bailee do not limit any of Secured
Party's rights or powers under other provisions hereof.

(a) Debtor agrees to direct Bailee to hold the Collateral as bailee and agent
for Secured Party; Debtor hereby acknowledges that Bailee does and shall hold
the Collateral as bailee and agent of Secured Party. Debtor agrees to execute
and deliver to Secured Party a direction letter to Bailee in the form attached
hereto as EXHIBIT A. All terms of the direction letter, including without
limitation the agreement and acknowledgment of Bailee, are incorporated into
this Agreement as agreements of Debtor, and Debtor agrees to direct Bailee to
comply with its agreements and obligations under such letter, and to direct
Bailee to agree to and acknowledge such letter as provided therein. Upon the
execution of the direction letter by Debtor, Bailee and Secured Party, as
provided therein, the direction letter shall constitute an agreement among
Debtor, Bailee and Secured Party.

(b) Except as otherwise specified herein or in any direction letter, Bailee
shall act or not act with respect to the Collateral solely in accord with
entitlement orders and instructions (including without limitation instructions
to sell or otherwise dispose of any Collateral, to designate securities as
Collateral (if applicable), and to deliver any Collateral to Secured Party)
given from time to time by Secured Party. Secured Party may exercise any of its
rights and powers hereunder or in connection with this Agreement or the
direction letter, including without limitation the agreement and acknowledgement
of Bailee, without the consent of Debtor.

                                     Page 8


                              Page 22 of 26 Pages



(c) Notwithstanding the foregoing, until Secured Party notifies Bailee in
writing to the contrary, Bailee shall not permit withdrawals from the Securities
Account. Moreover, Debtor agrees to take all steps, including without limitation
placing additional assets in the abovereferenced Securities Account, to ensure
that the value of the assets in the Securities Account at all times equals or
exceeds $2,000,000 (the "MINIMUM ACCOUNT BALANCE") as determined by Secured
Party.

(d) Without impairing clause c above, Debtor hereby directs and authorizes
Bailee, as agent with respect to the Securities Account, to effect replacements
and substitutions of Collateral on behalf of Debtor. Without limiting any other
provision hereof, all such replacements and substitutions of Collateral shall be
conclusively deemed to be Collateral and Debtor shall be deemed to have granted
a security interest in such items and assigned such items to Secured Party, as
more fully provided in SECTION 2 above. All substitutions and replacements shall
be satisfactory to Secured Party in its sole discretion, and (without limiting
any other provision hereof or of any direction letter) if Secured Party so
requests, no substitution or replacement may be made except with the prior
consent of Secured Party.

14. OBLIGATIONS UNCONDITIONAL; WAIVER OF DEFENSES. Debtor irrevocably agrees
that no fact or circumstance whatsoever which might at law or in equity
constitute a discharge or release of, or defense to the obligations of, a
guarantor or surety shall limit or affect any obligations of Debtor under this
Agreement or any document or instrument executed in connection herewith. Without
limiting the generality of the foregoing:

(a) Secured Party may at any time and from time to time, without notice to
Debtor, take any or all of the following actions without affecting or impairing
the liability of Debtor on this Agreement:

       (i) renew or extend time of payment of the Liabilities;

       (ii) accept, substitute, release or surrender any security for the
Liabilities; and

       (iii) release any person primarily or secondarily liable on the
Liabilities (including without limitation Borrower, any indorser, and any
Guarantor).

(b) No delay in enforcing payment of the Liabilities, nor any amendment, waiver,
change, or modification of any terms of any document or instrument which
evidences or is given in connection with the Liabilities, shall release Debtor
from any obligation hereunder. The obligations of Debtor under this Agreement
are and shall be primary, continuing, unconditional and absolute
(notwithstanding that at any time or from time to time all of the Liabilities
may have been paid in full), irrespective of the value, genuineness, regularity,
validity or enforceability of any documents or instruments respecting or
evidencing the Liabilities. In order to hold Debtor liable or exercise rights or
remedies hereunder, there shall be no obligation on the part of Secured Party,
at any time, to resort for payment to Borrower or any Guarantor or to any other
security for the Liabilities. Secured Party shall have the right to enforce this
