- System Three Resins Rotfix Wood Restoration Rot Repair, 24-Ounce

Works very well. Dries hard and reliably in different weather conditions.

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.

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.

A little pricey but works as described.

I have never used a product like this so I am comparing the product to the results I was hoping for and so far I am satisfied. Unfortunately, I won't be able to claim long term success but I do intend to continue with this product despite the fact that I don't know the long term effects. I used the drilling, drying, and filling technique between two layers of fiberglass (with a degraded balsa core) on a sailboat deck. The measuring and dispensing system works flawlessly. The penetration worked as described, maybe better than described. I used this product in a very dry, very hot outdoor environment, but still had the stated working time, flow rate and final harness. When I purchased this I intended to compare it to other similar products but based on my results I will just stick with this product for the remainder of my repairs. I omitted the final star for the unknown future longevity of the repair and container clean-up.

I have used both System Three wood repair products with great success. Both require mixing of two separate materials which is done very easily: the liquid "Rot Fix" wood consolidator/hardener comes with a mixing bottle with extremely clear directions how to use (so the ratio is consistently one to two parts). Likewise, the SculpWood comes in two different colors so after the first time mixing equal parts and seeing the resulting color, it is easy to mix more and know when the ratio is correct. As for performance: I could find no fault in either: the consolidator works wonders on clean but soft and unstable wood. Filling any holes and gaps with the SculpWood is actually fun: the material stays pliable for more than the stated 15 minute limit and it is even more flexible (but adheres well) than artist's sculpting clay. The 40 year old cedar fence I repaired using these products is not only solid where it once was unstable ( I used these products on a rickety fencepost), it also looks like it is all wood even on a few planks that are now 30% epoxy. A truly remarkable system and will save $$ on repairing what was once thought needed to be replaced, especially those items --like my cedar fencing-- where the same materials (eg. their dimensions and quality) are no longer available.

Our '73 Chris Craft cruiser had the bow anchor secured to the fore-deck by several brass fixtures, each with 3 holes, and each hole drilled thru the top fiberglas skin, the wood core, and the under fiberglas skin. None of the holes were properly "bedded" for leaks and all leaked water into the cabin whenever it rained. Over the years the deck sagged, and became so weak, we couldn't walk on it. We dried out the whole deck area for several weeks, then taped up the undersides of each hole, blew compressed air into the holes from the top until no vapor escaped from any of the holes, and proceeded to fill holes beginning from the back, progressing to the front. The 1st 24oz. kit filled half of the holes, so we ordered another batch, letting the first cure for a week. The 2nd batch exactly filled the remaining holes. What a fabulous product. Viscosity is nearly as thin as water, so it flowed into all the crevasses easily. The filler bottle is able to be squeezed, so the epoxy can easily be forced into the inner core areas. In the final analysis, our deck has been made ridged, and the sag which had increased for years, was magically restored to a level deck. Excellent product, and very easy to mix and use. So glad we didn't cut open the top skin, replace the wood core, and re-glass a new top skin. Would recommend this to anyone for fixing a rotted deck core.
