But now you can question why Easy Sand is unsuitable as a skim coat.

Easy Sand dry because of the chemical reaction. Skim coats need enough time to apply, but Easy Sand has limited time to apply. There is a high chance before you apply the skim coat properly, the joint compound will start setting and dry.

However, many pro painters apply Easy Sand for skim coats. But it is not recommended by the manufacturer. Here is the source.

What should I use for skim coat?

For skim coating, use a compound that spreads easily in thin layers and sands predictably, with lightweight all-purpose or topping compounds commonly chosen for broad surface work.

All-purpose joint compound and premixed compound all are good for the skim coat. It dries slowly and naturally, which provides you enough time to make the project successful and error-free. 

Here are recommended products which you can use.
