A wood hardener is a liquid mixture that dries quickly, penetrates deeply into the wood, seals the surface, and provides protection against factors like dampness.

It also offers protection against future decay.

So, it can be said that the purpose of a wood hardener is to protect the wood from rotting and harden the wood that is already rotten.

The wood may expand or shrink because of environmental changes in temperature and humidity.

When this occurs, water and moisture can easily seep into or out of the wood.

The outcome is that the wood could swell, wrinkle, or warp. These frequent changes in the wood make it difficult to work with.

The main purpose of a wood stabilizer is to stabilize the wood so that it does not go through any structural change.

  • Cost Variation

We consciously or subconsciously compare the price of a product while buying. You might also compare the price of wood hardener with wood stabilizer.

A wood stabilizer is a bit more pricey than a wood hardener. The reason behind this is that wood stabilizer is mainly resin-based product such as epoxy resin. It will cost you almost $100 to $150 per gallon.
