Rated 5 out of 5Â by Jack007repairs Amazing stuff. does exactly what it's name is.
This stuff goes in like water, so, seal up all your cracks. sets like a rock. prepare to pre-drill your holes. fills all the knoocks and crannies, then turns hard, hard, hard, Not brittle, like cement, takes screw threads w/o cracking. Adheres to every substrate I have challenged it with.... If, your wood is rotten, drill some holes, pound until the loose stuff is out. then fill'er up, better than new!! Love it!! Way cheap for what is does!! excellent performance!!
I leveled concrete stairs with this stuff( 1" thick) in 1991. I have moved but it is still there today (2012). I fixed door jams in rental houses, they are still swinging solid.. Still there.

Rated 4 out of 5Â by gimpy007 Great for patch jobs
Needed this for an old beat-up door and jamb on retail. This did great on the door and jamb, filling a cracks and even a missing chunk in jamb. Sands down very well for painting. The one thing it did not do well was hold screws. I still needed a larger strike plate for the damaged door jamb.

Rated 4 out of 5Â by DC4u Good cost efficient product
very cost efficient. Sets quick and hard (do not waste time); after sanding becomes part of whatever was being patched. Very durrable

I used this product to repair some wood rot on an outdoor window sill that was above sight level. It did a great job! I didn't know how to replace the wood, and I didn't really know any carpenters to call, so I thought I would give this a try after reading how to repair wood rot on the internet, some people recommended using Durham's Rock Hard.
I made a form to match the line of the window sill out of wire fabric and stapled it to the good wood, and I mixed several small batches of Durham's Rock Hard up and put on thin layers and let each one dry until it was built up and molded to match the window sill. I painted it, and the finished job looked great!
It's very economical to use. You have to make small batches, because when it starts to set up, there's a small time that you can work it before it gets hard. You should make a small batch to get used to the qualities before you apply it to your project so you know what you're working with.
I found it easiest if you have to make several batches for a larger job, is to mix up the Rock Hard in something plentiful and disposable- like paper cups or styrofoam bowls, and throw them out after each batch, and use a plastic putty knife and keep a bucket of water handy to rinse your tools in.
I have an old house, and I also used Rock Hard to fill in places on the exterior where the paint was chipped and had been repainted. I mixed up small batches, and used a putty knife to smooth them out, and blended them with a wet sponge, and painted them when they were dry, and the finished product looked good.
I hope this review is helpful, I needed several batches, and I just ran into the problem of running out of containers to mix it before I figured out to use the disposable containers, which made the job easier.

This product does not work as advertised or described. It did not harden, and mostly just became a flaky, dusty surface. Completely useless, wasting not only my time to mix and apply the produce, but also to return the product for full refund and buy a superior product to apply over the top of this garbage. In case you cannot tell from my review, I would not recommend this product to anyone, especially a friend.
