Painting a textured wall
Textured walls look great when they're fresh. A texted hides small plaster flaws, soften harsh light, and also it gives a home character. But a note! repainting a texted wall is not the same as repainting a smooth regular wall. Texture has peaks and valleys, and if your roller or paint system is wrong, you'll get patchy coverage, shiny tracks, and missed spots that only show up at night under downlights.
I learned this the hard way years ago helping a customer in the Inner West. They had a knockdown-style texture in the hallway. They used a standard 10 mm roller and a "one coat should do it" mindset. From the front door it looked okay. Then we switched on the pendant lights and you could see every lap mark and every valley that never got paint. The fix was simple: correct roller nap, better section control, and most importantly, the right primer and paint system.
This rewrite focuses on the main solutions you asked for. It keeps the content tight around textured wall repainting and the key products. It also adds Granosite Texture Solutions GranoImpact in the right way, so readers do not confuse a texture coating system with a standard interior repaint.
If you're comparing painters in Sydney for a textured-wall job, or weighing DIY versus professional painting services, this guide will help you pick the right system the first time.
Step 1: Identify what "texture" you actually have
This matters because GranoImpact is a texture coating system product, while most interior textured walls are repainted using standard wall paints.
A. Interior plaster texture (most common in homes)
Examples: orange peel, knockdown, light stipple on plasterboard.
Best approach: primer-sealer-undercoat (when needed) + interior wall topcoats.
B. Render or masonry texture (common on feature walls and exteriors)
Examples: cement render, bagged render look, masonry texture.
Best approach: a texture coating system. This is where Granosite GranoImpact can be a genuine fit because it is a pure acrylic elastomeric coating applied in different styles by roller or spray and is used as the topcoat in many Granosite systems.
Step 2: Use the right roller for texture (or you'll chase your tail)
On texture, the roller is half the system.
Light texture: 10-12 mm nap
Medium texture: 15-20 mm nap
Heavy texture or masonry: 20-32 mm nap
A longer nap carries more paint and pushes it into the valleys. Too short and you only hit the peaks, leaving that "patchy" look.
The core of the job: Texture primer and paint systems
This is the section most people skip. It's also the section that decides whether the finish looks even and lasts.
What "texture primer" means in Australia
In the market, "texture primer" can mean one of two things:
High-build texture primer for porous masonry, used under a texture topcoat system (example: Dulux Texture Primer). It is described as a high build primer and sealer for porous masonry, designed to assist application of texture topcoats.
Primer-sealer-undercoat used to unify absorption on interior plaster textures, especially after patching. These are not called "texture primers" on the label, but they do the job you need: stabilise porosity and improve adhesion.
When you need a primer or sealer on textured walls
Use a primer step when you have any of these:
- Patched or repaired sections
- Chalky or powdery surface
- Water marks or staining
- Uneven sheen already present
- Big colour change (dark to light, or vice versa)
If the wall is stable, clean, and previously painted evenly, you can sometimes go straight to two topcoats. But in Sydney homes with mixed repairs and older paint layers, primer saves you from flashing and patchiness.
System 1: Textured Walls - the Most Common Repaint Job
This is the one you'll probably see in about 9 out of 10 homes - textured wall repaints.
Recommended system (what most people use on their interior walls)
First things first - get the wall clean and dry.
If you've got patches that need some extra TLC, spot-prime them. Or, if the wall is looking a bit rough, put on a full coat of primer, sealer and undercoat - that usually does the trick.
Then just two topcoats of decent interior paint (and the safest look with texture is usually a low sheen finish).
Some Good Primer Options
These are the ones that are pretty widely available, easy to get your hands on, and designed to prime, seal and undercoat all in one go:
Taubmans 3 in 1 Prep Primer Undercoat Sealer - that's a premium product that dries in 30 minutes and you can recoat after 2 hours, and it sticks like crazy even on old enamels and glossy finishes - no sanding needed.
Taubmans Easycoat Prep - that's a low VOC (or Volatile Organic Compound, for those who don't know) and it's resistant to mould, dries in 30 minutes and you can recoat after 2 hours too.
Zinsser Bulls Eye 1-2-3 - that one is a bit more hardcore, but it's really good at getting a grip on surfaces and has a broad compatibility, especially if you need it to stick really well. It dries in 35 minutes and you can recoat after an hour.
What to do when stains are the problem
The thing is, textured walls have these hidden valleys where stains can build up and keep coming back. If you've got water marks or smoke stains that just keep returning, don't rely on two coats of paint to cover them up - get a dedicated stain-blocking primer instead. Zinsser 1-2-3 is a good choice here as it's good at blocking stains and sticking to surfaces, and you can recoat after an hour.
Professionals Tend to Get it Right
This is actually the point where professional painters often do a better job than DIY painters - it's not because painting is some kind of mystical art, but because they generally get the system selection right.
System 2: Masonry or render texture coating system
Now we’re talking about a different category, where GranoImpact belongs.
Granosite GranoImpact is described as a pure acrylic, high performance coating that can be applied in a variety of styles by roller or spray. It is positioned as an acrylic membrane with controlled vapour permeability, forming a barrier to external moisture while allowing vapour in the substrate to escape. Wattyl also describes it as an elastomeric coating and notes it forms the topcoat of many Granosite systems, with resistance to dirt, mould and fungi.
Where it makes sense in real jobs
GranoImpact is a strong choice when:
- you have rendered exterior walls
- you want a consistent textured coating finish
- the job is specified as a Granosite texture system rather than a standard wall paint repaint
Typical GranoImpact-style system (high-level, system logic)
- Substrate prep: clean, repair cracks, remove friable material
- Prime/seal as specified for that substrate and system
- Apply GranoImpact in the desired texture style (roller or spray)
- Finish per the system schedule
This is not "prime and paint the lounge". It's closer to a protective architectural coating workflow.

When to call us
DIY is fine for small, stable interior textures.
But it's worth calling professional painting services when:
- the wall has uneven suction and past repairs
- strong light makes flaws obvious
- you're dealing with a render or masonry texture system like GranoImpact
- it's a pre-sale refresh and you need consistency
A textured job can look "okay" in the afternoon and terrible at night. One of our good painters plan for that from the start.

Final note
Not every texture needs an expensive system. But every texture needs the correct category of products. That's the real difference between a repaint that looks "done" and one that looks like a weekend project.
