All wood putties are either solvent-based or water-based. Solvent-based wood putty is more common. It is used by the DIYer's and professionals alike. Water-based wood putty is growing in popularity because it is better environmentally and it does not emit solvent fumes. Besides, the water-based wood putty has becomes as good in its performance as solvent-based wood putty. Water-based putty takes longer to dry but very easy to clean up. You just use a little bit of water. Also, a water-based putty won't dry out if left open. It is important to note that any water-based wood putty is not suitable for a prefinished floor. A good quality water-based wood putty is TimberMate. TimberMate takes stains well, hardly shrinks, and does not crack out.

In contrast, solvent-based usually requires acetone or turpentine to clean it up. It is much more heavy duty and much faster drying than water-based wood putty. That said, it sands, stains and finishes very well. Solvent-based wood putty actually contains wood in its formulation. It has similar characteristics to wood. This wood putty will simulate real wood more than most other wood fillers on the market. Solvent-based wood filler also shrinks less than water-based wood filler.

Not all wood fillers have good adhesion and they are not all of the same quality. Good adhesion is extremely important when selecting your wood putty. A good quality wood putty should shrink and pop out. A good filler should sand easily when it comes time and should maintain a nice finish.
