Exhibit 99.1

           Ameron Makes Strategic Decision to Sell Coatings Business


    PASADENA, Calif.--(BUSINESS WIRE)--June 29, 2006--Ameron
International Corporation (NYSE:AMN) announced today that the Company
has agreed to sell its worldwide Performance Coatings & Finishes
business ("Coatings") to PPG Industries. The transaction is expected
to be completed within 30 to 45 days, subject to the terms of the
agreement and following regulatory review in Europe.
    "We are pleased with the anticipated sale of Coatings," stated
James Marlen, Ameron's Chairman, President and Chief Executive
Officer. "The exit from Coatings will allow us to redeploy resources
to Ameron's three remaining consolidated businesses, where we have
leadership positions. Ameron will remain a solid, focused company with
enhanced growth opportunities in the infrastructure, water and energy
sectors, through its Fiberglass-Composite Pipe, Water Transmission and
Infrastructure Products businesses and TAMCO, Ameron's 50%-owned
venture, which is the largest manufacturer of steel rebar in
California.
    "Coatings no longer fits our strategic objectives. In recent
years, the financial performance of Ameron's coatings business did not
meet expectations, partly due to difficult conditions in global
markets. Also, consolidations within the coatings industry provided
larger companies with greater economies of scale and constrained
Ameron's ability to grow." Coatings had sales of $210 million in 2005.
    Ameron will sell the worldwide coatings business, while retaining
certain real properties currently used by Coatings. Ameron will
receive $115 million, plus working capital adjustments, for the
business acquired by PPG. Additionally, Ameron plans to sell the
retained real properties in the next 12 to 18 months and expects to
generate additional proceeds of $15 million, based on current
estimates of market value. In May 2006, the Company sold property in
Brea, California, formerly used by Coatings, for $9.7 million. If the
retained properties are sold as expected, Ameron's sale of the
business and the sale of the properties, including Brea, should
generate cash of approximately $140 million after taxes.
    "The Water Transmission Group, through a product and geographic
expansion program, recently entered the growing wind-energy market as
a supplier of fabricated steel towers; and the Group is currently
expanding into Northern Mexico. We are pursuing an aggressive capital
plan to upgrade the Water Transmission Group's capabilities to
efficiently fabricate and paint large-diameter wind towers.
Demographic shifts in Northern Mexico demand new supplies of water and
present an opportunity for the Water Transmission Group to expand its
core pipe business.
    "New investment opportunities for fiberglass pipe are being
pursued throughout the world, such as the new Malaysian operation,
which came on line in 2006. Current demand for Ameron's fiberglass,
oil-field tubing exceeds capacity. The Fiberglass-Composite Pipe Group
is actively pursuing the placement of new capacity in South America in
2007 and is reviewing opportunities in the Middle East and North
Africa to serve oil-field and marine markets. Aside from growth caused
by a substantial increase in demand for its traditional products, the
Fiberglass-Composite Pipe Group is deploying new fiberglass products
into the water and wastewater markets in the U.S.
    "The Infrastructure Products Group is likewise evaluating major
expansion plans, as plants in Alabama and elsewhere operate near
capacity, serving the growing West Coast and Southeast markets in the
U.S. Lastly, the aggregate and ready-mix operations in Hawaii continue
to grow as construction in Hawaii remains strong.
    "The sale proceeds will enhance the Company's already strong
financial position. Ameron has the cash and debt capacity to grow. We
plan to reinvest a portion of the proceeds to grow both internally and
through related acquisitions. As we stated in the past, we are
selective about making acquisitions and will only acquire companies
that create value and are priced to provide superior returns.
Additionally, we are actively evaluating alternative uses of capital,
such as purchasing Ameron stock, that balance the long-term health of
the Company and maximize the return for our shareholders.
    "We have consistently improved the quality and repeatability of
earnings over the years. The new Ameron will be a streamlined, more
focused company, with growth potential, and will be in an enhanced
position to continue to create shareholder value," concluded James
Marlen.
