Will it hold wood screws in-place once dry?
Asked by: KayakRon
It will. If not, you can always put a bit of gorilla glue in and let dry for a couple of hours, then drive in the wood screw.

Will it stay put (stick in-place) as a filer, while drying when packed vertically between two between 2 surfaces?

You will have to make it thicker than for other applications. I haven't done this but I expect it to be doable.

Would this be a good product to fill small voids in oak cabinets prior to painting them? The oak seems fairly grained and I would like them as smooth as possible.
Asked by: Steve
That should work perfectly. Much better than those wood filler.

As I have read through these reviews I was easily able to spot the difference between the weekend DIY's and the Professional's. The first thing I will say is if you are having any trouble with this product then you are not using it correctly. You MUST mix it up to the correct water to powder ratio. If it is too thin then you are using too much water. If it is too thick you are not using enough water. Pretty simple. As for the guy that said it was complete garbage and he wasted his time and money. I would have go along with he has no clue on what he was doing. Over the decades I have found this stuff does exactly what it is designed to do. Get hard and patch the holes. I had to practice with it a few times the first time I have ever used it but after learning how to mix it I have not ever have any more problems with it. Tomorrow I am going to try to mix some water based stain with it to see if it will hold the stain.

Rated 5 out of 5 by from 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.

I’ve used it many times with equally good results he had.It mixes easily with water, but only mix what you will use in 10 minutes or less as it dries and hardens quickly.It spreads easily, dries hard & stable, can be sanded.
