Mix up just the amount of Wood Patch or Full-Trowel Filler whenever you need it! This environmentally friendly system allows you to refill your container and eliminate unnecessary packaging and waste. And you get the same premium performance as our pre-mixed products. Smoothly fills cracks, nail holes, gouges and broken edges. Takes stain like hardwood and sands easily. Bonds tightly, mixes easily in water with a drill mixer. The cost is 30-35% less than our pre-mixed wood fillers. Three 14-lb. bags per case. Each bag makes up to 1.7 gallons of filler. And it's freeze-proof in its powdered form, so you can leave it in your truck year-round!
