Timbermate Wood Filler is a water based interior grade wood filler containing no acrylic or latex, ensuring that your product application will not shrink, sink, crack or fall out. Timbermate Wood Filler is also a highly cost effective solution, as it has an indefinite shelf life (if the product dries out simply add a few drops of water) and comes in a tub rather than a tube. Timbermate Wood Filler comes in 14 pre-mixed colours, but can be mixed with any stain or colourant to achieve the desired colour.
