Wood Fillers & Stains FAQs
Can wood filler be stained?
Some fillers accept stain differently from surrounding wood. Test the complete system on a sample or hidden area.
Why does filler crack after drying?
Movement, excessive depth, poor adhesion, moisture or unsuitable application thickness can contribute.
When should filler be sanded?
Sand only after the product has dried or cured as specified. Premature sanding can pull or smear the repair.
