Restoring the Past with This Old House: Introducing Dura-Fix Epoxy Wood Filler

For decades, This Old House has been a beacon of inspiration for homeowners looking to restore and rejuvenate their properties. With its knowledgeable hosts and expert craftsmen, the show has provided invaluable guidance on tackling various renovation projects. One such craftsman who has left an indelible mark on the program is John Stahl, renowned for his expertise in woodworking, painting, and restoration.

In the realm of home improvement, few challenges are as daunting as repairing damaged wood. Whether it's a weather-worn porch railing or a rotted window sill, wood deterioration can detract from a home's aesthetic appeal and structural integrity. However, with the right tools and techniques, even the most dilapidated wooden surfaces can be revived to their former glory. Enter Dura-Fix, and John’s prior invention Flex-Tec, a revolutionary two-part epoxy wood repair product dispensed from a dual cartridge caulk gun that has been making waves in the world of restoration.

On the Salem Project with This Old House

John Stahl, a seasoned restoration carpenter and frequent guest on This Old House, showcased the effectiveness of his former invention: Flex-Tec.

John returned to the lab in 2012 and invented Dura-Fix.

Inspecting the existing conditions of the wood windows to determine the extent of the repair.

In 1995, John was tasked with repairing several two century-old original wood windows in Salem, Massachusetts suffering from extensive rot and decay, Stahl turned to his first invention: Flex-tec to breathe new life into the historic windows. The first step in the restoration process involved removing the paint from the lower areas of the sill and sash to reveal the rotted portions of the windows. Despite the age of the window, John found less than 10% of the wood required treatment.

John knew not to trust the condition of the paint film alone. Often the condition of the paint can mask the true condition of the underlying wood. “Sometimes the paint is in worse condition than the wood. It’s necessary to remove the paint to get a sound assessment of the underlying wood and revealing the extent of the decay”

John meticulously assessed the condition of the wood, identifying areas where his material could work its magic. Unlike traditional wood fillers, which often fail to provide lasting results, flexible epoxy formulations boast of unique properties that bond to the wood fibers and move with the seasonal changes creating a durable bond that withstands the test of time.

2-part epoxy resin technology is used to repair the rotten wood

After preparing the surface and mixing the two components Stahl began applying the epoxy to the damaged areas of the window. Thanks to its smooth consistency and easy workability, this 2-part epoxy adhered seamlessly to the wood, filling in cracks and voids with precision. As Stahl meticulously sculpted the epoxy to match the contours of the original woodwork, it became evident that this was more than just a temporary fix – it was a transformative solution capable of restoring even the most compromised wooden surfaces. As the epoxy cured, Stahl marveled at the remarkable transformation taking place before his eyes. What was once a decrepit window now bore the hallmarks of historic craftsmanship and care, thanks to its innovative properties. The final result was nothing short of spectacular – a testament to John Stahl's expertise and the transformative power of his engineered epoxy materials.

Leading the way John Stahl and This Old House continue to demonstrate that with the right tools and techniques, anything is possible – even turning back the hands of time to restore the beauty of the past.
