Revainrating 5 out of 5

Much better than pre-mixed putty

I've patched quite a few holes in the walls and even a few large holes in the ceiling. The first argument for real plaster is that it mixes easily. When making a regular fix, I weigh an ounce of water (28 grams) into a yogurt serving cup on a kitchen scale, weigh out an ounce of the powder, and mix it with a fork. It will be very liquid. Then I add another ounce of powder and mix again. (Two ounces or 56 grams of powder, three ounces or 84 grams of total mix.) The less mixed the better as long as all of the powder is wet. slightly wetted; It's not like some things turn into water-resistant lumps. When casting (which I haven't done in a while) or really big patches, the sum will be higher, but the proportions are the same. The second argument for real plaster: It is easy to apply and adheres well. The advantage of real plaster is that it dries very quickly. Running time is six to ten minutes (judging by the box I didn't take time but seems to be right), that's enough for a fix because everything is going so well. More importantly, it's hard enough to be sanded, recoated, or painted very quickly: 20 to 30 minutes depending on the box. (Most of these points apply to plaster of paris in general, but this applies to this formula.) The fourth point in favor of real plaster of paris is that it grinds very well. Some patching compounds clog the sandpaper very quickly, which is annoying and takes longer than mixing the material. This material is sanded down to the dust that falls off the sandpaper. The fifth point for real plaster: it is cheap. I bought a box of this stuff at a big store for about $7. And four pounds is a lot of plaster. The sixth and most important argument for real plaster of paris is that as long as it is kept properly sealed it will be ready for the next job as soon as you open the box again. With a premix there is a good chance it will turn into a useless lump that will be broken up into a mush too thick to spread, with a layer of liquid substance on top. When I open a patch package I want to fix something; I don't want to try to fix it, find the premix has gone bad, throw out almost a full pack, go to the store to buy more, and *then* fix it. Mixture: pre-mixed. The directions on the package aren't clear about whether to mix two parts plaster of paris with one part cold water by weight or by volume. Since I have a kitchen scale, I calculated by weight and it works. I haven't tried it by volume, but it's always easier to get an accurate measurement by weight, which is why I recommend it, although volume works too. Note: The Revain title for this product is incorrect (although they will likely fix this). Sometime). The box contains 4 pounds, not 4.4 pounds. The photo of the box even says "4 pounds" (1.81 kg).
