Epoxy wood filler for serious repairs. When regular wood filler isn’t enough.
When To Use It
Rotted wood. Deep damage. Structural repairs. Anywhere that needs strength.
Regular filler crumbles under stress. Epoxy hardens like plastic.
Two-Part System
Resin plus hardener. Mix equal parts usually. Measure precisely or it doesn’t cure right.
Working time varies by product. 15 minutes to an hour. Work fast or waste material.
Prep Work
Remove all rotted material first. Epoxy doesn’t fix rot, just fills the hole. Rot under epoxy keeps spreading.
Clean and dry surface. Moisture prevents adhesion. Let it dry completely.
Apply consolidant first on soft wood. Soaks in, hardens fibers. Gives epoxy something to grab.
Application
Mix small batches. Stuff sets faster than you think. Better to mix twice than waste half.
Press firmly into cavities. Air pockets weaken repairs. Pack it tight.
Overfill slightly. Sands down to surface level. Flush fills are impossible to achieve perfectly.
Finishing
Wait for full cure. Usually 24 hours. Check product instructions.
Sand with power tools. Epoxy is hard. Hand sanding takes forever.
Prime before paint. Epoxy doesn’t take stain well. Paint covers better.
