Product Description

Real Milk Paint wood filler is a resin-based wood filler, developed for the plywood and furniture industries, to repair wood fibers in plywood, furniture, laminated beams, cabinetwork, and other woodworking applications. It molds like putty and is consistent, uniform, waterproof, and fast-setting with minimal shrinkage. Made with genuine wood flour it can be sanded, stained, sawed, planed, or drilled like ordinary wood.

This wood filler works best when it is used to fill small holes in wood or large or deep areas of cracks. Spread evenly into cracks, damaged edges or holes, let the wood filler dry completely, and sand smooth to the surface being repaired. Paint or stain to match the wood surface. It can also be revitalized with acetone if becomes dry in the can.

How to Use Wood Filler

Now that you’ve gathered your supplies, you’re ready to use wood putty or wood filler to repair cracks, even out large gaps or fill holes. You can also use this process for covering nail holes, and it works equally well on unfinished wood and finished wood. Also, before you begin, make sure you have chosen the appropriate wood filler for the area where you intend to use the object you’re repairing. For example, water-based wood fillers are not a good choice for outdoor projects, which respond better to most wood fillers that have oil-based compounds. We don’t recommend the use of color changing wood fillers prior to painting with Real Milk Paint as they can at times revert back to their pink/purple color once the milk paint is applied over top. Follow these steps to use wood filler properly.

Directions to Apply Wood Filler Effectively

  1. For best adhesion, cracks or defects should be clean and dry. If you plan to color the wood filler, you have the option to add the stain or Real Milk Paint to raw wood filler prior to use.
  2. Press wood filler firmly into defect by hand or with putty knife.
  3. Fill deep holes (1/4″ or deeper) in two or more wood filler applications. Allow each layer to dry before the next application to have the repaired area perfectly level.
  4. Lower temperatures require longer drying periods.
  5. Avoid getting excess material on surfaces around the cracks or hole filled area.
  6. When dry, sand flush with surrounding wood surfaces.
  7. Surfaces may be milk painted, stained, varnished, lacquered, waxed, shellacked, or sealed with Finishing Oil when the wood filler is dry to achieve a more professional looking finish.
  8. Close container after each use, place the lidded surface down and the artwork in the upright, readable position.
  • Try staining a sample piece to check color match before staining your completed work. To help color match, add a small amount of stain to wood filler before using. A little care in staining or painting will reward your efforts. Use commercial solvents, such as acetone, to clean up.
