WEST SYSTEM 407 Low-Density Filler – For Effortless Fairing and a Flawless Finish

Achieving a perfectly smooth, fair surface on your boat hull or composite project can be a time-consuming and labor-intensive task. The endless cycle of applying, curing, and sanding can be frustrating. WEST SYSTEM 407 Low-Density Filler is the industry-leading solution designed to dramatically simplify this process, delivering professional-grade results with significantly less effort. It is the go-to choice for boat builders and repair professionals who demand a superior finish without compromise.

The primary advantage of the 407 Filler is its incredible ease of sanding. This filler creates a putty that sands with remarkable ease, saving you valuable time and physical exertion while reducing airborne dust compared to other fillers. It is a specialized bead based filler mix used to make fillers that are easy to sand but maintain a good strength to weight ratio. This unique characteristic makes it the ideal choice for large-scale fairing projects on boat hulls, decks, and other composite parts where a smooth finish is critical without adding unnecessary weight to the structure. Its ability to hold a "feather edge" means you can blend repairs seamlessly into the surrounding surface without chipping or cracking, ensuring a truly invisible repair.

When blended with WEST SYSTEM epoxy, the 407 Low-Density Filler transforms into a smooth, creamy putty that is easy to apply and shape. It excels at filling voids, gouges, and depressions, creating a flawless substrate before priming and painting. The consistency of the filler can be easily controlled to suit your specific application. For detailed instructions, add 20% to 40% by weight to a West System epoxy mix. This allows you to create everything from a pourable, self-leveling slurry for filling wide, shallow areas to a stiff, non-sagging putty for vertical and overhead applications, giving you complete control over your work.

After curing the color is reddish-brown, providing a clear visual contrast against most substrates. This makes it easy to see your progress during the sanding and shaping phase, helping you to achieve a perfectly fair and even surface. Whether you are a professional boat builder undertaking a major refit, a marine repair technician fixing dings and gouges, or a dedicated DIY enthusiast restoring a classic vessel, the 407 Low-Density Filler is an essential component for your maintenance and repair toolkit.

Stop fighting with hard-to-sand fillers and elevate the quality of your work. Choose WEST SYSTEM 407 Low-Density Filler for a superior, lightweight fairing compound that ensures a smooth, professional, and durable finish every time. Make your next boat maintenance or composite project your best one yet
