Drywall texturing

REA's picture

I'm remodeling my downstairs bathroom and laundry room and ready to do a spatter/knockdown type texture treatment on the new drywall.  I purchased some bags of Sheetrock Brand "wall and ceiling spray texture (unaggregated)".  I was reading the preparation directions on the bag.  It states to prime coat the drywall with Sheetrock brand First Coat or a latex flat wall paint BEFORE texturing to "equalize the surface porosity and to provide uniform color". 

What is the correct way to proceed?  I was planning on texturing THEN priming/painting the walls.

Prime, texture,paint.


I been wanting to procrastinate, but I keep putting it off

we always texture before primer - with a knockdown, the mix will take a lot longer to "gel" on a primed surface, but on raw sheetrock it sets up pretty fast, so you can come behind and knock it down right after spraying. 

The problem is when you're remodeling, and some of the walls are painted, and some are new sheetrock, the new sheetrock will be ready to knock down before the painted walls.  In that case, I might prime before texture.  If its an orange peel, I don't think it would matter much. 

But I would think if you primer before texture, you'd have to primer again after texture.

Orange peel (straight spray) I'd texture first and then prime. Never had a problem doing it that way.

But if you're doing a knockdown, you need to prime first, because the texture will set up much faster on your seams than on the paper, and you won't get an even knockdown, it'll be runny on the drywall when it's READY on the seams.  My brother-in-law did it the wrong way on his living room ceiling and I notice it nearly every time I go over there. You can really pick out the outlines of the 4x8 sheets.

I prime, texture, paint.

We mix primer in the texture mix, so the texture is primed and ready for paint.


The bad news is you've done exactly the right things to be exactly where you are today.

The correct way  to proceed is .... follow the manufacturers instructions.

(post #77178, reply #6 of 6)

According to the manufacturer's (USG in this case) instructions, they recommend applying a coat of "interior flat latex wall paint with high solids content" or...their own brand "Sheetrock Brand First Coat Flat latex paint" BEFORE texturing.

Here's a copy and paste from their instruction sheet for the "Sheetrock Brand Wall and Ceiling Spray Texture (Unaggregrated)"

- Surface Prep

Surface Substrate must be sound, dry, clean, and free of oil, grease, mildew, efflorescence, and other foreign materials
Preparation and/or contaminants. Product, air, and surface temperatures must be maintained at a minimum of 55 °F (13 °C)
throughout the finishing process when using joint compound, primer, and texture products.
New Drywall Treat joints and nailheads with an appropriate USG Joint Treatment System.
New Concrete/Plaster Age at least 60 days before texturing. Remove form oils and efflorescence and grind down
form lines. Fill cracks and holes, and level concrete surfaces with SHEETROCK® Brand DURABOND® Setting-Type or
EASY SAND™ Lightweight Setting-Type Joint Compound or Cover Coat® Brand Compound and let dry.

- Substrate Priming

Application of a prime coat is necessary to equalize surface porosity. After prepared surfaces have thoroughly
Priming dried, apply a prime coat of SHEETROCK® Brand First Coat flat latex paint or a good quality interior latex flat wall
paint with high solids content. Prime coat should be applied undiluted and allowed to dry before decorating.

- Mixing

Use a clean vessel equipped with power agitator. For initial mix, stir powder into recommended amount of water,
agitating during powder addition. Allow to soak for at least 15 min.—longer in cold water. Remix until a creamy,
lump-free mix is obtained. Adjust spray consistency by adding small amounts of powder or water. Overthinning
can create an undesirable finish or “soft wall” or chalky condition. Overdilution can also entrain excessive air
and foam.

- Application

Using suitable spray equipment, apply by machine to create the desired effect. The application rate will vary
from 10 ft.2/lb. (2 m2/kg) to 40 ft.2/lb. (8.2 m2/kg) depending on texture pattern. Maintain 55 °F (13 °C) minimal
air, product, and surface temperature during application and until surface is dry. Avoid drafts while applying, but
provide ventilation after application to aid drying. Do not use unvented gas or oil heaters. May be painted after
overnight drying. Unpainted surface is not washable or scrubbable. Match spray equipment to job size and time
requirements. For rapid application and high production, use either a piston pump (7:1 or larger) or a rotor stator
pump matched to a compressor of adequate size. Preferred texture patterns can be obtained using a Binks
18D spray gun (with #57 or 58 fluid nozzle with R27 or R30 fan cap) or Binks 7E2 spray gun (with #46 fluid
nozzle with #190, 191, 290, 291, or 292 fan cap). Fan caps with a rectangular orifice reduce overspray and
waste and will provide greater spray control. Good results can also be obtained using a short pole gun with a
3/8 nozzle orifice. Small jobs can be completed using a Hopper Gun or Goldblatt Pattern Pistol with separate
