When it comes to mixing up exterior plaster it looks like mortar mixers are very expensive. We found this scaled back model made by Rigid that mixes right in 5 gallon buckets, but the reviews are
terrible and it doesn't seem like it will hold up. It's a pity, because the concept is great, and it seems like someone could make a well made version of this. After reading about LImestrongs
recommendations of mixing plaster for at least 7 minutes, we thought it would be helpful to find a solution that frees up someone having to hold a drill for that long. Any leads on automatic mixers such as this one that can mix directly in 5 gallon buckets? Or possibly leads on econcomial mortar mixers?
