Review: Best wood hardener ever ! - This is the best word hardener I've ever used!

## Features

- Premium Epoxy: RotFix is an ultra-low viscosity, solvent-free, low-odor wood epoxy that penetrates deeply into soft, punky wood substrates
- Easy To Apply: Brush our penetrating epoxy over the repair area; Some wood substrates are highly porous and will absorb the RotFix rapidly
- Versatile Application: Our epoxy resin hardens punky wood, and it can also be used as a stand-alone wood consolidant product for firming up punky wood prior to primer or paint application
- Curing: At 70°F our wood repair epoxy can be sanded with 150 grit sandpaper in 24 hours; Make sure that RotFix is completely deglossed before applying primer
- Tips and Tricks: RotFix epoxy wood sealer does not kill rot fungus or keep it from returning; For long-term protection from rot and decay, first use EndRot Borate Powder

### ⭐⭐⭐⭐⭐ Best wood hardener ever !
*by S***O on June 4, 2025*

This is the best word hardener I've ever used!

### ⭐⭐⭐⭐⭐ This is a log cabin savior.

System Three End Rot System is awesome, found log rot in a few spots on my 34 yr old engineered log cabin. After intense research I found their product to be strong, easy to apply and the only thing I trust on my house.

### ⭐⭐⭐⭐⭐ Great for repairing rotted wood. Excellent wetability and slow cure.
*by M***. on July 18, 2016*

I used this to repair some delaminations on a fifth wheel camper. Water intrusion had caused the luan plywood to fall apart and the fiberglass skin was coming off. I mixed this up and put about 100CCs per sq ft and then braced the fiberglass back in place with 2x4s and plywood. After curing it was as good as new. I also used this on part of the subfloor that had water damage and light rot. It is probably stronger than before. I recommend mixing this in a wide paper bowl. I tried mixing 1.5 oz in a cup and it got hot and cured way too fast. I used 16 gauge syringes to inject this in the desired area and it flowed through the needle fine. Once spread out over an area it cures fairly slowly allowing good penetration into rot. I will be buying this again to keep for future repairs. Very happy.
