Skim Coating Fragile?

I have skimmed several walls and from time to time I wonder how fragile these coverings are. Comments?

Not as fragile as it seems. Depends on what you use. Most use powder an mix it so they can control the drying time.

Some mixes are: Durabond, this is not sandable and used for base coats. It actually can be ground down with sand paper or wet "sanded" but it's a waste of time. Durabond is very strong.

Setting type joint compound comes with a variety of drying times from 5 min. up to 90 min. Obvious advantages, it's fairly strong, dries hard. Some are more sandable than others but all are sandable. Plus3 Easysand is a good one. IMO.

Toppings come pre-mixed in buckets. Sheetrock and Plus3 are common. These are really sandable but not as strong as a setting type. If you get a setting type compound in a bucket, it will be stronger than topping. Topping is made for easy of application.

There's another topping, it's orange. I don't use it. It's the easiest to use but very "weak".

Sorry I missed this. Premix sheetrock.
