Clear Wood Grain Filler


When painting over cabinets, we recommend using Aqua Coat White Cabinet Grain Filler.  It has more visibility than the clear, better adhesion, and higher solids performing better in less coats saving you time!


Easy-to-sand clear gel wood grain filler for filling the pores in woods (such as oaks, mahogany, ash, and hard-to-fill woods). Can be used on raw wood or after staining, sealers, or topcoats. For a finish as smooth as glass.

Refinishing your kitchen cabinets or upcycling furniture? Get a smooth, glass-like finish with this professional method: de-gloss, sand, apply 2-3 coats of Aqua Coat Clear Grain Filler, sand lightly and then we recommend using Aqua Coat X-119 Sanding Sealer and Aqua Coat Clear Lacquer. People who used our grain filler when refinishing their cabinets love it:

"Easy product to use. Easy cleanup."

"Easy to use, no offensive odor, and does its job by filling in the grain."

Clear Wood Grain Filler Directions For Use

Surface Preparation: Surface must be clean and dry (free from all dirt, oil, wax and polish) before using the Aqua Coat Clear Wood Grain Filler. Sand surface thoroughly. Remove all dust with a vacuum, forced air or damp cloth (water).

Directions For Use: Aqua Coat Clear Wood Grain Filler should be applied after the piece is stained, and/or a seal coat (Aqua Coat “X-119” Sanding Sealer) has been applied.

  • Stain and seal coat must be dry and lightly sanded with 220-grit or finer sandpaper.
  • Grain Filler can be tinted with water-soluble colorants or dyes.
  • If no stain or seal coat is used, you may apply Clear Grain Filler to the raw wood.
  • Grain Filler may be applied with a soft cloth, using a circular motion, much like applying a paste wax. Or work Grain Filler generously into open wood grain pores with a small squeegee or flexible putty knife.
  • Inspect to see if the grain is completely filled, then scrape or squeegee to remove excess.
  • Let dry 30-45 minutes, then lightly sand with 320 grit paper.
  • If grain is not completely filled, repeat the application process.
  • 2-3 coats of Grain Filler are recommended.
  • Allow over­night dry time and lightly sand before applying top coats.
  • Yellow grain filler applicator included

Not so good

I was really looking forward to using this for an oak table. After staining and sealing, i put on one very thin coat. It dried in white splotches inside the grain so i tried wiping out of the grain with a damp cloth. After that, the varnish went on uneven, as if going over wax. It was a fail for me.
