Reviews of the Top Wooden Cabinet Grain Fillers

1. Aqua Coat Best Wood Grain Filler

Aqua Coat is an excellent product because it has the ideal consistency—thin enough to apply easily without smearing yet thick enough to accomplish the job. This primer is a transparent gel that will penetrate the grains and seal the pores.

The Aqua Coat Best Wood Grain Fillers are the best on the market since they are safe for use, inflammable and incombustible, have low VOC content, and dry quickly. It can be applied quickly and cleaned up with water, making it ideal for filling wood grain.

With its low shrinkage, it has excellent adhesion to the wood’s pores and very manageable thin paste consistency.

2. Timbermate Water Based Wood Filler

To be honest, we were quite surprised by its capabilities. First, the Timbermate Water-Based Wood Filler can be stained, making it a multipurpose tool for mending damaged wood anywhere inside the house. 

Further, it only takes less than an hour to dry, while many other tube fillers might take up to a day. Therefore, you may go about your day-to-day activities without spending too much time trying to hide imperfections in the wood.

Moreover, as with other water-based fillers, it is non-toxic, a major plus in our book.

3. CrystaLac Clear Wood Grain Filler

The CrystaLac Clear Filler is water-based, so it goes on smoothly and dries crystal clear/ It takes only two or three coats to fill the exposed grain of woods like Koa, walnut, and oak. A quart will last a long time because of its loose consistency.

It’s super simple to work with because it’s not granular and doesn’t need to be thinned. It also doesn’t call for volatile chemical reducers, nor be stained and colored to match the wood, but can be dyed using water- or alcohol-soluble colors.[1]

Because of their transparency, clear grain fillers lack the substrates required to embed themselves in natural wood grain.

Wooden Cabinet Grain Fillers Buyer’s Guide

Type of Filler

Wood grain filler can be either oil-based or water-based. Fillers made from oil have been used for as long as oil-based finishes.

Since it can be easily cleaned up with soap and water and dries in a fraction of the time of conventional wood grain fillers, waterborne wood grain fillers are quickly becoming the norm.

It’s a common misconception that applying a water-based filler necessitates the same type of finish. In contrast to oil-based fillers, water-based fillers like Crystalac and some dewaxed shellac products are more forgiving when receiving the final clear finish.

Formulation and Durability

Grain fillers typically come in an opaque “neutral” tone or are colored to mimic the appearance of different woods. When using an opaque filler, you will almost always need to adjust the hue somewhat to achieve the desired result.

Water-based wood grain fillers dry water-clear, saving you more time and effort. You won’t need to worry about achieving a spot-on color match or removing every trace of extra filler.

In terms of aesthetics, the filler color greatly affects how the wood finally turns out. A transparent grain filler gives the impression of greater depth when used on open-grained wood. 

The CrystaLac we listed may be colored with any water- or alcohol-soluble dye, allowing for endless possibilities for creative creations.

Amount

When making a purchase, the price will always be a major consideration. The good news is that you can discover a wood grain filler for your home renovation tasks that won’t break the bank but will still look great when you’re done.

FAQ

Is a wood filler the same as grain filler?

A wood filler is not the same as a grain filler. A wood grain filler, not to be confused with “wood putty,” is used solely to fill grain pores. A wood filler is used to patch significantly larger holes and fissures in wood.
