HV-65 Pint of High Viscosity Natural Liquid Latex Mold Making Rubber

High viscosity means it brushes well, does not slide, and dries quickly. I was surprised to see some reviews complaining of long drying time. Assuming you use it properly, in thin coats and wait till each coat gets tacky before applying the next, it dries quite quickly and you can help it along with a hair dryer. Just remember to make the first "beauty coat" very thin and covering all of the surface. My molds come out strong, resilient, peel off the rock faces I'm molding with little effort, and capture very fine detail.

This product works great as a protective layer over items I do not want to get paint on while painting. It is easily removed when my work is done and clean up is a snap.

Worked great on its own but i needed to build a whole mask so i mixed it with flour and that worked wonderfully, on a separate part i mixed it with corn starch to see the difference and it worked okay but was better with the flour. I also used cotton balls soaked in the latex and that worked perfectly. Tl;dr: easy to use, dries quick but not too quick, sturdy

Price keeps going up. Good product. Works great to repair halloween masks.

I used this to modify a lap table, so I could use it with diamond art and my recliner. I used rubber latex first then I put foam rubber on it the size of my diamond tray. Then I just let it dry. Instead of ruining my lap table by using glue, I used rubber latex, which does the same thing only when I get done if I want to, I can just peel this right off of there and then my table looks just like it did when I bought it new. Also, this will stay as long as I wanted to even for another 50 years if I don’t peel it off. It’s as good as glue only better.

This latex deteriorated completely in one month and a slight pull tore it. I have other latex molds I made 20 years ago that I have gotten dozens of casts from. I have used this material more than a dozen times so I know what to expect. This latex is worse than worthless wasted hours and hours of my time. The one cast I made showed a good impression was not made. I used my bottle days after receiving it. Was kept at room temp. Since other reviewers seem to think this material is okay maybe something happened to my bottle with the supplier. But that certainly speaks to horrible quality control.

Don't use it for making homebrew sealant for tubeless tires for your mountain bike. It is too runny.

Bought this product to make molds of rocks for my model railroad. Before using it, I went on line to get some input on how to use it. Several things to keep in mind when you make a mold of something. First, make sure the pattern is clean. Second, spray it with silicone spray (from your auto parts store). Third, you need to apply multiple coats of the product. I found 15 coats worked well. Be sure to daub the material on for a thick coating. The container does not lend itself to using a brush, so I poured a little in an old pill bottle and used a 3/8" artist brush. I let each coat dry and cure for at least 3 hours. The material is white when you apply it and it dries clear. The finished mold peeled right off of the pattern. I made plaster casts, I used an old towel, bunching it up to support the mold. It worked great! The most important thing to remember is to take your time.
