Durham's 076694000015 1-Pound Rockhard Water Putty

Excellent product!!! Can be used for so many things. Great value for your money. Powder form gives it long shelf life.

This wood filler is a game changer. The powder can be diluted with water to any desired consistency, either flowing or a putty, and it dries quite fast into a very hard surface. Easy to sand too. The advantage is that one can mix what ever desired amount, unlike the premixed putties whose leftovers harden prematurely when stored.

This stuff is always constant and reliable. I use this all the time to fix dry rot in wood or gap filler on my wood projects. Excellent stuff.

Easier to use than putty for glazing glass in doors on furniture and more stable. Can be mixed with dyes as well.

Great stuff to fill in troubled OSB and Oriented wood sub floors.

This is, without a doubt, the best stuff there is. Other brands of wood filler either dry too soft, th consistency of drywall joint compound, or take forever to dry to a workable hardness. Not Durhams. Thought gypsum based, it dries rock hard, matching the wood onto which it is applied. Though some complain about it drying too fast, this is really no inconvenience. A little bit of prior planning and preparation eliminate the problem. Mix just enough for a small area. Don't be afraid of having to mix multiple small batches. Buy yourself a rubber or silicone mixing cup and you'll be one happy camper.

I've used the product for many years to patch holes in plaster-coated walls inside my house. It's easy to mix and apply and sets up rock hard.

Great wood filler - good price. Have to experiment with the mix consistency and water ratio, but always turns out great - used for more than 20 years
