How to replicate finish on drywall

[Shawn Pottschmidt]

I'm trying to match the finish on some drywall. The existing finish has an overall look like fish scales. I think they used a brush of some sort to make fan like sweeps that overlap each other. If this makes sense to you let me know what I need to duplicate it and blend with the new wall. Thanks in advance Shawn

I agree with John; try your hand at it and if you fail, Lowe's sells a hard texture roller that you can roll with compound on the wall to create a new texture that is as fast as painting. 

This is an option: https://www.lowes.com/pd/TexMaster-Tools-Sponged-R...

Though I don't highly recommend it as the texture it puts out is very thin and you have to dilute compound dramatically to get the brush to even take the compound.

This on the other hand has provided a TREMENDOUS result and works phenomenally with dilution or straight compound. It provides a nice textured finish. 

We tried both these brushes to cover up an abundance of wall imperfections after removing 12 layers of wallpaper in our Master bedroom and bathroom and the second option (Blue Hawk brand) worked out great. 

Here is a picture of our master bath as an idea.
