## Description

System Three Resins Rotfix Wood Restoration Rot Repair, 24-Ounce - Automotive Adhesives And Sealants - desertcart.com

Review: Good product - Works very well. Dries hard and reliably in different weather conditions.
Review: I liked the fact this was so easily molded to fit ... - I used two different epoxy products restoring the wood rot in an outside deck. I liked the fact this was so easily molded to fit vertical defects and dried true and accurate. It was very easy to clean up and not at all messy. It sanded well and looks great painted. I used the pretreatment too but didn't like it as well as a product I found later and will mention in a moment. The pretreatment has to be mixed and is hard to apply from the squeeze bottle. I ended up mixing it a small cups with syringes and applying it with disposable brushes for some deep, verticle surfaces. I also used a wood filler and separate hardener produce from Bondo. This worked very well on horizontal surfaces because it was soupier. The Bondo much messier and much harder to clean up. It sanded well and filled the defects nicely. The Bondo pretreatment came in a can with a brush in the lid, no premixing. This was very easy to apply. The one drawback was the screw top lid glued itself shut and I ended up opening the can and pouring it into an old glass jar to keep using it. I used a disposable brush several times before I had to throw it away.

## Questions & Answers

**Q: Can this be used on painted wood?**
A: Well, sort of. To be used correctly, you need to scrape away rotten or damaged wood which naturally exposes bare wood. I used it to restore several rotted exterior window sills that were painted. After the repair and repainting, two years later, they still look great. Good stuff!

**Q: Do I need to pre-treat my rotted wood "pockets" (after removing debris) before filling with Rotfix?**
A: No need to pre-treat. Make sure you've cleaned out as much rotted wood and resulting debris as you can. Then mix the A and B solutions according to the instructions and apply. It really is amazing how the RotFix hardens and strengthens the area. Good stuff! And so is the SculpWood you can follow up with to patch or rebuild the area. Another great product.

**Q: What is the drying time for this resin?**
A: I used it last summer so I cannot recall exactly how long each step took to dry. But certainly, it was within a day or two and I was sanding and shaping the repair. Great stuff, though. Saved me a lot of $$$ over replacing rotten wood. Once painted, you can see no evidence of the repair.

**Q: does this product contain borate to actually kill dry rot fungus?**
A: Dry rot occurs when the wood gets wet, then rots, then dries out. Once dry, the rot does not spread until it gets wet again. Do keep in mind that the porous nature of dry rot readily soaks up moisture and starts back up the rotting process. So it is real important to address the ability for water to get to the wood. That is the only true way to stop the rot. Now, it is true that dry rot is more vulnerable to insect damage - carpenter ants, carpenter bees, and termites. And borate or copper wood treatments will certainly help dissuade them. However, once a wood hardener such as this product is added, that also dissuades them. So I'm not sure how much more the preservative really helps.

### ⭐⭐⭐ Received Old Stock — Disappointing, but Workable.
*by G***K on July 23, 2025*

Some reviewers have warned about heat and fumes when mixing the two components. I experienced neither one. The product is supposed to have just 5 minutes of working time before it sets up. Mine allowed 5 hours of working time, or possibly even more, before it showed any indication of beginning to cure. After application, 5 days passed before it had hardened sufficiently so that I could apply deck stain to the treated areas. Until then, a thin, slick, somewhat sticky or greasy film of uncured epoxy had remained on its surface. I am disapointed but I can use it. I'll just have to be careful when applying it to any vertical surfaces. I may have to use a hair dryer to speed the curing process.
