Pros:

  • Convenient packaging
  • Versatile product
  • Easy to de-nib

  • Good brand

Elmer's is generally not a brand consumers think of in the woodworking realm. They're more well-known for helping schoolchildren make arts & crafts projects at home.

However, their E855 wood filler product is of very high quality. It's much like a two-part epoxy putty that you can apply over any gaps, holes, or cracks in your wood projects.

Epoxy is, by its nature, denser than wood, and so it will sink in when you apply it. This helps seal the wood so it does not continue to rot, while also making the holes and gaps less visible.

Frequently Asked Questions (FAQ)

What is the best wood filler for large gaps?

Of all the wood filler options I tried, TiteBond III is clearly the best wood filler for large gaps. While the other wood fillers worked for the smaller gaps, they left larger holes that needed a lot of additional work to fix.

Also, the Liquid Nails Wood Filler is too difficult to spread and fill larger gaps properly.

A gap that is 1/4" or larger between surfaces, should not be filled with wood glue. At this point, a two-part epoxy or polyurethane should be used to fill the hole.

What is the best wood filler for exterior use?

Polyurethane-based fillers are excellent for exterior use.

Polyurethane-based fillers deposit a single-layer covering around the damage. The ingredients in the filler polymerize into a solid, flexible polyurethane resin that dries by solvent evaporation. It is resistant to the sun's ultraviolet rays so that it won't shrink or crack and it can be painted over to blend into the surrounding wood.

Be sure to use an oil-based sealer first if you are working on an exterior project because the water-based sealers are more likely to dissolve the polyurethane fillers.

What is the best wood filler for decks?

If you just ask yourself that question, you'll probably have your answer already. The best material to fill in wood is wood. That may sound strange, but there is a reason why. The best wood filler for deck boards is a product whose consistency is close in hardness and overall compositional makeup to that of the wood boards it is to be used to fill. If you have de-barked cedar deck boards then, depending on what you have been using when they are wet, splinters of the cedar may be readily apparent and may become embedded in the softer wood filler that you apply.

That means the easiest wood filler for deck boards to use is one made of cedar because it matches the board's composition. The second best material is one made of pine because it too is made of wood. The undesirability of using softwood materials for filling repairable/re-usable wood surfaces is only because the wood will be apparent in the finished look.

What's the difference between wood putty and wood filler?

Three words: drying time, drying time, drying time!

Both materials work great for filling holes in wood, but they are a bit different.

Wood putty is just what the name implies, it is more of a putty than a filler. It dries a bit more slowly than wood filler and doesn't really harden the way wood filler does. It completely fills up the hole, but then takes a bit longer to harden.

Wood filler can be either pressed into a hole or spread with a trowel. Sometimes it comes premixed, with a resin already mixed in. Wood filler takes longer to dry but it is still fairly flexible once dry. You shouldn't flex wood putty that's dry.

The biggest difference between the two types of wood fillers is drying time. All you have to do is check the label to know which one you have.
