Some would say that all ultra light spackling is the same, but those people have obviously never seen Red Devil’s Onetime “Lighten Up” Spackling. This unique product is pink… yes, that’s right; it’s pink. It wasn't done that way for women or for supporting breast cancer research, but rather so that you would know when it was dry. Although the spackling goes on pink, it turns white as it dries. That’s to let you know when it’s ready to paint. Once it’s white, you can paint it without any fear of messing up your spackling. As with other ultra-lights, you can fill even larger holes with it, without having to worry about it sagging, cracking or shrinking.
3M makes a wide variety of products, all of which are excellent. Their ultra-light spackling is made with nanotechnology, which means that it uses materials that are so fine, they fall into the realm of nanotechnology. This is a spackle and primer in one, so that the paint will go on without showing where the repair was done; with no shiny or dull spots to give it away. The spackle is paint-ready 30 minutes after application.
Dap is one of the biggest names around in caulking and surface preparation products for the home. This is a personal favorite of mine, which I've had excellent results using. The spackling goes on extremely easily and stays right where you put it. Shrinkage and cracking are non-existent. Although spackling is usually applied with a putty knife, I find that using my fingers with this, especially for filling nail holes, works remarkably well. I’m not sure exactly how quickly it’s supposed to dry, but I've painted over it as little as ten minutes after application.
Patch-N-Paint is another common lightweight spackling, which can be found almost anywhere. This one boasts use for both indoor and outdoor applications, which is a little unusual. Normally, these products are limited to indoor use, but this one can be used outdoors as well; a real advantage. The spackling dries extremely quickly, saving you time between prep and painting. Sanding is not required; unless, of course, you put it on too heavy.
This lightweight spackling is essentially the same as the other Red Devil product listed as number one, but doesn't have the color changing capability. I suppose there might be some applications where the chemical used for color changing could cause a problem. This product spreads easily, providing one-coat filling of a large variety of applications. It’s water-based for easy clean-up. Like the Phenopatch product, this one can be used both indoors and out.
