DURHAM'S Rock Hard Water Putty - 4lb Container

well, honestly i have never used this , but Hubby says, we gotta order this stuff- the best thing ever ..he says - for filling holes, cracks in wood . It does dry rock hard, it’s sand able, paintable ..it’s been around for decades i think. He’s used it many times, and since its in the form of a powder, you can mix up only what you need, as you need it, which is why it’s economical and there’s less waste. Price is reasonable, and ordering it online saves us having to drive to the local hardware store, who- by the way- sells it for twice as much as you can get it online- which is crazy town !! Anyway, if you’re a do it yourselfer, carpenter, handyman or lady- whoever you are- this is great stuff !! We know for a fact that! And cheers to you !!

This works really great. But a little goes a long way. I probably only needed to buy a 1 lb container. This price was so good that I had no idea that it was a 4 lb container when I bought it. I did not look close enough. This thing is huge! A four pound container of this is going to last me the rest of my lifetime. But I'll take it it's really great. Which is pretty easily just keep adding product if you have too much water vice versa. Goes on really easy. I had to fix a door jamb that was riding away and I didn't want to replace it because I have no idea how to check all that project. This was good for a quick fix. It's been about a year and holding up well. It really does dry like cement. Highly recommend.

This is a great product that should be in any DIY arsenal, especially at the outstanding price with the add-on program here. Costs at least double this at the local orange home center. This is a fine cream colored powder, you mix it with water. Mix it thin, it is a great pore/ grain filling skim coat. Mix it thicker, it's putty that will fill knot holes, etc. It says that it does not shrink but of course as it dries it will shrink a little, necessitating more than 1 application on deeper holes, etc. It also sands very well, you can get a great smooth finish on it. As with any putty it will take stains, etc but you always need to experiment prior to using it on your final project- it'll take stain, but differently than the surrounding wood. I mostly use it as a skim coat on plywood that I'll paint. I can save money with lower grade plywood, build my shelf/ cabinet etc, fill the grain and imperfections with this, sand it back flat and get a perfectly smooth & flat surface for painting. As the name says, it does dry rock hard, no joke. I would not say that it is structural- I guess you could mix in some fibers or aggregate to strengthen it, but I have not experimented with that yet. Anyway, if you build stuff, especially if you're a woodworker, you should have a tin of this stuff on the shelf. I just finished a tin that I bought 5+ years ago and it was still good.

This is a great material. I've used it on wood of various types. It dries very hard, so you want to make sure it is a smooth coat. My last can lasted for 20 years before I used it up. It never goes bad like regular wood putty. No smell, dries slowly.

good stuff but you need to be aware of some realities of using it. the thicker you make the mixture the faster it dries to its rock hard final state. add water in very small amounts until you get a feeling for how much water to use because it is far too easy to add too much water and wind up with a mixture that is too thin for your need. it washes off skin very easily, but not clothes. you can use a wet towel to clean an area before the stuff dries but there will be a white haze when the area dries, the haze comes off with a second wiping with a wet cloth. if you use it on outside wood be aware that the wood expands and contracts with temperature change. this stuff does not. the end result is that there will be a fine "crack" where the putty ends and the wood begins. i suggest using a flexible caulk to seal the crack but you need to minimize the area the caulk is spread on (or paint the caulk when finished.) a tip: if you want to work on multiple filling points have a wet (not damp) cloth that you can use to wipe off the instrument you are using to apply the putty, otherwise the putty will dry on the instrument and make it impossible to immediately reuse. you will not be able to wash the cloth and get the putty off. update 10/10/20 it sets up rather quickly depending on how thick or thin the batch is. make small batches if you need to use it for an extended period (say longer than 15 minutes). you can salvage some of a batch that is starting to setup by adding small amount of water - but not the entire batch. since it is water based, drying time will depend on humidity and temperature. the more you use in one place the longer it will take to completely dry. it is readily dissolved by rain so when the top is dry and you expect rain, put a THIN coat of waterproof caulk on the surface to repel rain; you may want to sand it off. something i learned is that when using it outside temperature variation causes some, not much, edge separation. since the stuff dissolves in water, unless there is good drainage, seal (like using clear caulk) the edge to prevent water from standing in contact with dried putty.

This stuff is great. Been using it for a long time and the results are always consistent. It doesn't shrink or crack. Easy cleanup. Nice and smooth, sands down easily, paints well. I dont stain filler so I cant comment on that. But i would assume you can get good results with a little experimentation. It dries a light pine color. Powder doesn't dry out in the containers like pre mixed, it mixes very easily and applies smooth. You dont need much water with this.

This product is amazing stuff. Like the directions say its 3 parts powder to 1 part water which was pretty close to where i wanted it to be. I went for a light thick consistency that was able to stay in the mixing bowl when turned upside down but very easy to spread. This stuff has a pretty decent working time and dries pretty quickly once applied; My particular surface was dry to the touch within 30 minutes. Once this stuff dries, it is hard as a rock, which is exactly what I wanted. I have also not observed any shrinkage like with other products. It sands down nicely and doesn't fall apart and doesn't look half bad with poly on it either. I am super happy with this product!

Have not used it yet for repair - but did mix a little to check for hardness and quality. Result was better than expected. I had flood damage on a laminated floor and bought WOOD FILLER to see how it would work. https://www.amazon.com/gp/product/B001E5L19O/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 Unfortunately, it would cost a lot if using WOOD FILLER and it is not really meant for flooring. The price of Rockhard Water Putty makes it great value considering how much you get. I like the fact that you only need to make up the amount you need - so there is very little waste, if any. I happened to leave the lid of the WOOD FILLER not fully closed and when next time I came to use it it had all dried out. No issue with Rockhard Water Putty. I have ordered some different colorants from Amazon so should get something close to the color I want for the flooring. https://www.amazon.com/gp/product/B00BHKKUXY/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1. If you have a large project that needs repair I think this is a great product to have around the house or work-shop. I am not expecting the Laminated Floor to look perfect but will be happy if it does not look so unsightly. Will post before and after photos once I have completed it. Seems silly to give a review before using it properly - but from the little I did mix up, plus the quantity you get, in addition to little or no waste, makes this a really good buy. I spent hours on the internet looking at all type of floor repairing - epoxies, chemical mixes etc. For price and quantity this is a really good buy.

Designed for use as a general wood filler, this product is excellent for it's hardness and the fact that it does not shrink. It sands beautifully and can be drilled. even tapped in some circumstances, and has very good adhesion qualities. It does need to be mixed with water, which can be considered a detriment to some, while others would appreciate that, in it's powder form, is exempt from frost damage, unlike many other wood fillers. I have seen professional pool table assemblers use it to seal and fill the slate joints of the playing surface on pool tables and have used it for that purpose also. It dries quickly when applied thinly and with a quick sanding, renders the slate joints invisible. Lots of uses, great product.

Amazon lässt mich meine Bewertung nicht veröffentlichen, daher lasse ich das Foto für sich sprechen. Alles versaut und der Eimer war halb voll.

With the price of lumber right now I decided to reuse my 40 year old door jambs for my bedroom renovation to save some money. The back sides of the jambs where in new like condition and just needed the holes filled from the old nails. I usually use a quick setting drywall compound for wood fill but it doesn't really have the strength required for this kind of job. I am happy to report that Durhams works like magic and its very similar to mixing quick set. I did two coats and it dries fairly well. I am going to wait overnight for it to cure completely. Its sands very well but I would advice doing it layers vs one big blob. I am very happy with this filler and will be using it more on my upcoming renovations. It's made in the USA.

very good stuff have been using this product for years and so glad i was able to find it ,as none of the stores carries it in my city.

Easy to fill in cracks and holes in wood with this product. Sets up and stays firm. Easy to put Diamond Wood Finish Oil Based Varathane over it. Lasts well!! Best product for this need that I know.
