works great on dry-rot
used it on some window frames with dry-rot and it helped to stabalize the wood. I used the putty to fill in some of the severe damage as well.

This works!
It's tricky to figure out how much to mix, so my first time, I mixed way too much; I poured the leftover mix into some kitty litter for disposal. WOW When it had solidified in the litter, it seemed stronger than wood. I think this will fix my rotted spots on my porch extremely well. Do use this before applying SculpWood - another terrific companion product. SculpWood is waterproof and sculpts and sands like a dream. The repairs I made to my porch posts are INVISIBLE, thanks to these products. I even rebuilt the bottom of a baluster with it.

Dry Rot Repair
I used your product Rotfix and also SculpWood to repair dry rot in a deck door. After removing as much of the dry rot as I could I applied the Rotfix. It hardened and stabilized the remaining wood very well. I used the SculpWood to fill the resulting void. Unfortunately, I ended up a little shy in one place and had to build it up. I tried more SculpWood but found it did not adhere to itself as well as I would have liked. Had to fuss with it a bit. In the end I would caution others to be sure to overfill the material so they don't have to fill in a little to get the patch level. Other than that the two materials did a great job for me. I would certainly recommend them and add that though it was expensive it was well worth it.

Fixing damaged wood siding and window sills.
Very helpful product. Does what it says. Easy to mix correctly with the kit supplied. Only challenge is that it sets up more quickly in the August heat.

Low vis epoxy.
Low viscosity epoxy. The kit works well for large batches but not small ones. I used it to stabilize end grain in weathered wood and it worked well. Viscosity was thicker than description led me to believe

Great product - works as intended
We have old house (1869), my husband is using this to strengthen and repair basement window frames. His only complaint is knowing how much to mix. I'm not sure you can help him with that.

Can be used on damp wood. Any other products that I looked at required the wood to be dry.

Bought one kit, and it works just as the box says. Very pleased with the product. I can repair all my windowsills now.

Works great, very flowing. Soaks into the dry rot really well. Just pour several light coats and let it soak in. Be sure to dam up the area with painters tape if the rot goes all the way through or you'll have some drip out.

Thought we might be able to repair something that ended up needing replacement.

My wood floor planks of my balcony were joined by a wood filler that is coming out with the sun and rain . Can I use this product to repair the slits?
Sydney C on Jan 18, 2017
BEST ANSWER: Yes. If there is softening or rot in the wood planks, I suggest that you use the Rot Fix 2-part liquid epoxy and a syringe-type glue injector to put the mixed liquid into the bottom of the slits. If the cracks are larger, you should consider using the putty-type companion epoxy product, SculpWood. Keep in mind that because these planks are exposed to weather, other parts of the planks may eventually split and rot as result of taking on and retaining water. I have been using epoxy products (these and others) to repair exterior wood surfaces on my 1897 Victorian house. I have a poplar tongue and groove floor on an exposed part of a front porch. Over successive seasons I have been making epoxy repairs (both liquid and putty) to more and more new problem areas. The areas previously repaired with epoxy do not rot, but the all-wood areas next to them can and usually do rot if they don't dry out.
I am restoring a rotten window sill. I have a wood epoxy resembling a putty ball for the rotten cavity. I need to saturate beneath the lower part of the cavity. May I use a different more liquid epoxy brand for this task?

BEST ANSWER: Yes- Rot Fix
Can I use on the underside of my wooden caravan floor. Will it soak in and work upsidown?
Richard H on Mar 25, 2018
BEST ANSWER: Well probably. It's about the thickness of motor oil when mixed. You might mix a small amount and try a chip brush as an applicator. I'd trim the bristles of the brush down so they're only an inch or inch and a half long and then you're using this as a flexible spatula.
You might do multiple coats versus one larger amount dripping on everything.
How many window sill can I fix with one kit?
Brian R on May 30, 2017
BEST ANSWER: I fixed 2 window sills trim on my front door a large spot on my garage door and had guitar a bit leftover. You should be able to do several window sills. It works great.
can this product be applied to the entire surface of a turned bowl so it can be sanded?
Vern T on Mar 18, 2017
BEST ANSWER: Why are you considering an epoxy... Is the bowl rotted? Epoxy is difficult to sand, compared to wood. So you'll spend more time sanding, and any raw wood will be sanded down faster than any patches embedded with epoxy, so you could end up with low spots. Maybe you want to use a filler instead? And if the bowl is for food, you'll need to be concerned about the epoxy's suitability for food contact. (The MSDS sheet downloaded from this site should say something about that I think.)
Would this work for a ship hatch coffee table that we have in our living room? It has wood rot on the side of it and strips of wood come off every once in awhile.
Danielle H on Jun 23, 2018
BEST ANSWER: I've used this product for exterior dry rot and it worked great. Think of this as a thinned out epoxy that gets absorbed into the wood, similar to a stain. This product does leave a glossy finish on the surface.

It should help to solve your problem. If there are loose pieces of wood strips, I would try to get some of the product underneath to act like a glue. If the strips are a veneer that is just coming up, I would consider gluing them down in which case this product may not be required.
can you get it in larger quanties ?

Is RotFix Wood Restoration and Repair suitable for structeral repairs?
James P on Aug 1, 2015
BEST ANSWER: In my opinion probably not. It is a repair that stops existing wood rot and will restore the shape of existing piece of wood . This product will not be able to carry much weight. Do not know your situation but if repair is of weight bearing material I would try to replace rather than count on this to carry load. Hope this helps.
