System Three RotFix Penetrating Epoxy Sealer, 1.5 Quarts

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

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.

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.

Easy to use. Works as intended

I have a really old house this is really wonderful stuff but it’s quite toxic! I used a sponge applicator first and that fell apart, I used an old paint brush for my next session and that was hardened when I went to apply more, so I moved onto an old toothbrush. All of the sudden I heard this hissing and smoke and the plastic from the toothbrush caused a reaction and the mixture was about ready to blow up in my hand! Really crazy I had to throw dirt on it to get the smoke to stop. So just beware what you use to apply this !!!

I bought this to repair water-damaged wood in an area where the deck met the house. It saved me from having to rip out and replace everything. The after-repair look is great.

if you have old or rotting wood, this stuff really does the trick. Infuses the old wood with a nice hard polymer that's easy to work. Highly recommend.

No part B in the package. Two part epoxy with only one part is worthless. Now I am finding there is no return policy. Not happy, I rushed shipping to meet a deadline.
