1. Bondo Home Solutions 20082 Wood Filler. You won't find a more long-lasting exterior filler than Bondo Home Solutions 20082 Wood Filler. It's an epoxy filler that requires mixing, and as a result, it provides a highly durable fix that won't shrink or break with time.
Selleys No More Gaps Exterior is the ideal solution for filling gaps and cracks around and between weatherboards, eaves, and exterior windows & doors.
The Elmer's Carpenter's Wood Filler is the perfect product for minor repairs and touch-ups, and one of its championed qualities is how it resists shrinking and cracking once it has dried. Also known to last longer than its competitors, you can easily sand the wood filler once it has dried out completely.
Epoxy wood fillers are fantastic materials for big projects and repair jobs. They are one of the best products for fixing rotting wood and wood that has been damaged over time.
Epoxy can also be mixed with sawdust to create a paste. This works for holes that are large or deep holes in wood. Epoxy requires a bit more skill to use, but it's ideal for large holes or wood that is extremely rotted. There's not much a craftsman and epoxy can't fix!
However, if you plan to leave the piece of wood natural and just apply a clear coat, you can tint wood filler with a wood dye to match that natural color. Since wood filler dries hard and doesn't flex with the expansion and contraction of wood during temperature changes, it isn't suitable for exterior applications.
Sandable, Paintable and Stainable. Easy water clean-up. Interior/exterior use.
If you've never worked with wood, you may wonder about the difference between wood putty and filler. Woody putty is oil-based and ideal for finished wood pieces in moisture-prone areas. Wood filler is water-based and ideal for filling small holes, cracks, and gouges, in wood you'd like to paint or stain.
There are some differences between the two products: Most notably, Bondo is marketed for a speedy repair and can be sanded in 15 minutes and painted in 25. Bondo Wood Filler can also be stained, though it's unlikely that it will absorb stain the same as the surrounding wood.
Brummer Exterior Wood Filler is a ready to use, waterproof filler that can be used under most finishes including polish, lacquer, varnish and paint. It is also resistant to sea water so is used for most marine applications. Brummer exterior wood filler will not shrink, crack and can be drilled or sanded.
Depending on the exact formula, as well as the humidity and size of the repair, wood putty may take as long as 72 hours to dry. Even after it dries, the putty remains flexible so it can be used for exterior repair jobs.
Epoxy can also be used as a wood filler. It's more durable than water-based wood fillers and dries to a harder finish. Epoxy is an adhesive, so it bonds with the surrounding area rather than sitting on top. The patch won't soften when exposed to moisture, making it a better choice for exterior use.
Should I use wood filler or caulk? To sum up the difference between caulk and wood filler, caulk is to be used to fill in corners and gaps between two materials, whereas wood filler should be used to fill nail holes and other damage on flat wooden surfaces. Wood filler can be sanded and caulking can not.
