DURHAM'S Rock Hard Water Putty - 25 Lbs Drum

I used it over foam to make a faux tree. This stuff is magic. Need it putty consistency less water. Need it thin for spreading more water. Once its dry hard as a rock.Warning if it's too thin it will crack.

Mix small amounts at a time. Sets up very fast. After a few applications you get better at using this product.Very useful product.

My boyfriend loves this product!!! Patches cracks in fixer upper house we just bought. Love it 100% wish I could give it more than 5 stars!!!!

Well. I got some rotten wood and this did a good job covering the holes. I liked the jumbo large size can. Mix with water and apply the putty over the hole. Good for botched jobs and ideal for wood cracks and projects. Make sure to have paint to cover the tan color. Very sloppy and great for making a mess! Use with adult supervision. I would recommend to any art teacher. ;o) Clean up can be fun. With the right mixture, turns hard fast within 5 10 minutes. This product is a lot like cement.

So we disassembled, repaired and reassembled 3 flights of 150 year old stairs in our house... Leaving LOTS of nail holes, cracks, and other imperfections to fill. This stuff did the trick perfectly AND I only went through half of the stuff. It dries very hard, but not at all brittle... adheres very well. It's only been 4 months since I did the work but I don't doubt it will be durable.The only negative is you have to work in small batches because it dries quickly... I wanted to sponge and scrape the stuff before it set fully (it would more difficult and dusty to come back and sand it later). Very happy with the product though.

We used it to fix our concrete water fountain. It's great. Bonds well and hard as nails.

This product is amazing. I remodel homes for a living and this product is phenomenal. You simply mix it with water. Apply. Dries quickly. Sand it to shape and paint. It can be quicker than tearing out and replacing. I will buy this in bulk from here on out. 5 stars all day

Best way to buy this stuff way cheaper then big box store home improvement stores. Drys quick can be sanded easy and dries rock hard. I use it to blend wood panels like wood putty but stronger.
