Will a pancake air compressor be enough ?

I was wondering about getting my air compressor, but wanting one that can handle the chore of sraying texture on drywall. It's a oil lubed, 2 hp 4 gallon one that puts out 7 cfm a @40 psi, and about 6 cfm @ 90 psi? or will I need one that has a bigger tank? I know texture guns like about 6 to 7 cfm at 40 or 90 psi.

any help would be great!

You have to know whether the texture gun's capacity is rated at 40 OR 90 psi. It makes a difference.
Also, if this is just for occasional, casual use then you could likely get away with a much less expensive unit than if you were doing this more often.
When the air tool air capacity closely matches the compressor's output, the unit will run all the time. Inexpensive compressors generally have a much shorter duty cycle than ones for commercial use and will not stand up to continuos running.

The size of the air tank does not really increase the unit's capacity. A larger tank will only increase the amouint of air available for a few seconds, until the compressor restarts.
The size of the tank is what controls the amount of time the compressor runs when using small amounts of air.
A larger tank will allow the unit to run longer and be off longer between cycles. This is better for the unit.
