What are the differences between using a premanufactured texture and mixing sheetrock mud with paint to texture. I am completing the wet sanding process and am ready to texture. With the looped roller method will it cover small imperfections better than the spray method?

It basically comes down to the type of texture you want. Either one will cover SMALL imperfections. You don't need a hopper and a compressor for the roller texture. I've never used a "looped" roller. I have used just a long nap (3/4") roller to match texture that was already there. As far as mixing the paint in with the mud, you have to be sure to get it thoroughly mixed to get the color consistent. And the same amount of paint in each bucket of mud if you're doing a large area. I'd recommend mixing (thinning) with water to get the consistency you need to roll the mud and come back later and paint. I personally don't care for any texture. Easier to patch a painted surface. Just my preference though......

I personally feel spraying is better, but that's an opinion. Depends on the size of the job.

You will be investing time and money on texturing, so do some homework first.
Prime before texture equalizes both porosity and surface texture differences. It provides a base that equalizes the absorbsion rate variations between the drywall face paper and the finished joint compound when painted, delivering a uniform finish coat. This ensures that no areas of texture will fail prematurely.
When texture comes off in sheets, it is because of dust under or no primer.
When doing knockdown un-primed, the texture dries at different speeds, creating a different texture as you drag a blade over it. You will see the difference.


The U.S. Gypsum Association, (a member probably made your wallboard and mud you are using) requires you to prime before texturing with a water based product. (A.2.3)

Their warranty against ceiling sag requires a prime before texture (A.2.4)
(A.4.3) prime before painting final
(A.4.3.1) prime prior to texturing, again

If your ceiling texture (whichever style) fails, and you didn't prime before texturing, you lost your manufacture's warranty.
