Heidi G. Petz
President and Chief Operating Officer at Sherwin-Williams
Thank you, Jim.
I'll begin with the Paint Stores Group. Third quarter Paint Stores Group sales increased 3.6% against the challenging 21.5% comp. The increase was driven by continued effective pricing and higher pro architectural volume, excluding new residential. Segment margin improved sequentially and year-over-year to 25.9%, driven by pricing discipline and moderating raw material costs.
Protective and marine was the fastest-growing in the quarter, driven by strong volume, as sales increased by a double-digit percentage against mid-teens comparisons. Industrial flooring, infrastructure, and oil and gas applications remain key drivers. In our pro architectural end-markets, commercial sales were strongest, increasing by a high-single-digit percentage versus a high-teens comparison.
Residential repaint sales increased by a mid-single-digit percentage amid continued softness in existing home sales and against a 20% comparison. While this is a solid performance in the current environment, we are not satisfied, and Res Repaint continues to be our largest opportunity for growth. Property Maintenance sales grew by a low-single-digit percentage against the mid-20s comparison. New residential sales were down mid-single-digits with volume down high-single-digits against the mid-20s comparison. As we've previously noted, we anticipated new residential would be challenging near-term, given prior softness in single-family starts.
We expect our continued share gains and new account wins to become more and more apparent as starts improve. Our DIY business was down low-single digits against a very difficult low-30s comparison. From a product perspective, interior paint sales were up low-single digits and exterior paint sales were flat both against double-digit comparisons in last year's third quarter.
Sales in our Consumer Brands Group decreased by 4% in the quarter, primarily due to the divestiture of the China architectural business and software DIY demand in North America, which was partially offset by selling price increases. Sales in North America, our largest region decreased by a mid-single-digit percentage against a double-digit comparison. The Pros Who Paint category continued to grow, while DIY demand remained muted by inflationary pressures on consumers. We continue to invest here with our strategic retail partners for growth. In other regions, sales were up high-single-digits in Latin America and low-double-digits in Europe. Sales in China were down high-double digits as we completed divestiture of the business on August 1st.
Adjusted segment margin was 13.8%, which was lower than a year ago, primarily due to lower sales volume and lower fixed-cost absorption due to lower production volumes. Sales in the Performance Coatings Group decreased 1% against the low teens comparison. Volume decreased by a high-single-digit percentage but was partially offset by positive low-single-digit contribution from pricing, FX, and acquisitions. Adjusted segment margin increased to 19.1% of sales, primarily due to pricing discipline and moderating raw material costs. Sales in PCG varied significantly by region.
Sales were strongest in Europe and increased by a mid-teens percentage. Latin America sales increased by low-single digits against a mid-teens comp. North America sales decreased mid-single-digits against a 20% comp. Demand in Asia remained weak with sales down double-digits against high-single-digit growth a year ago.
From a division perspective, growth was strongest in our industrial wood business, which was up by a low-double-digit percentage against a mid-single-digit comparison. This growth reflects our ICA acquisition, share gains, and a potential bottoming of new residential construction. We expect to gain further momentum in this business as we closed October 1st on the previously announced acquisition of Germany-based specialized Industrial Coatings Holding, comprised of the Oskar Nolte and Klumpp Coatings businesses.
We are gaining share and seeing steady demand in Auto Refinish, where sales increased by a mid-single-digit percentage against a high-single-digit comparison. Sales in Coil and General Industrial both decreased by low-single-digit percentages against challenging comparisons and varied widely by region. Packaging sales were down by a mid-teens percentage against the high-single-digit comparison. We anticipated this decline, given the near-term destocking by brand owners that we described earlier this year.
Packaging sales in the quarter were also slightly impacted by the fire at our Garland, Texas plant. Our business continuity team is executing our contingency plans to minimize customer impacts from this event near term. Longer-term, we continue to feel very good about our position and growth prospects in this end-market, and we expect to bring additional capacity online at our Thouars new [Phonetic] France plant by early 2024.
With that, let me turn it to John for his comments on our outlook for the fourth quarter and the year.
