A first-time homeowner with a horrible beige, textured 'feature' wall. The wall and ceiling are painted in two different boring beige colours: one flat, one textured - the eighth wonder of the world is why this would be done in the first place. BUT...how do I prepare the textured wall for clean paint?? I am going to just go white given the air con and random power point (the ninth wonder of the world).
Welcome to the Bunnings Workshop community Sarah (@sarah1982). It's wonderful that you've joined us, and many thanks for your question on paint preparation.
Are you happy to leave the texturing and paint over it? If you apply a low-sheen paint, the texturing will be less noticeable but still detectable. If it weren't for the high spots of that textured paint being extremely glossy, it would just be a case of cleaning the wall down with sugar soap and painting over it. In your case, I'd suggest using Dulux 1L PRECISION Maximum Strength Adhesion Primer White for an undercoat as it binds very well to glossy surfaces.
Can you please do a quick check for us to make sure that it isn't wallpaper? Have a look for joins along the width of the wall. The gloss on the high spots is a little suspicious, as I'm not sure how that would be achieved with paint when the low spots are dull. It's a look most typically seen in textured wallpapers.
Let me mention @redracer01 to see if he has any other suggestions.
After removing some TV cord covering, it actually looks like they've added a layer of something over the top of the original wall. See pics below. I think I have a bigger job on my hands than I first thought. I will now need to remove the power point in the middle of the wall, gyprock/fill it, then fill and smooth other gaps where the plasterboards (that appear stuck on, not nailed in) join. I've seen a few videos now on the paint preparation so am comfortable there (clean, sander, the Duluz you mentioned), now it is a matter of really filing in all the gaps and smoothing it all out I think!
Welcome to Bunnings Workshop. After looking at the photos you posted, I just want to be clear on the information that another panel was placed over the standard gibrock wall? It's this panel you are now trying to paint over? Or was it they used a special paint to give you that rendered patch look? If it is a panel it must have a hardened polish finish on top. I can only suggest a very thorough wash with sugar soap to scratch the finish and as @MitchellMc recommended to use the Dulux Precision primer. It should be strong enough to grip on to the surface and provide you with a good surface to paint on. Please keep us updated with your project and if you have any other queries please post it here on workshop.

That's an interesting situation @sarah1982.
Now that you've mentioned this, I can clearly see the panel joins across the wall.
Can you tell what these panels are? Are they some plastic or acrylic? I have my concerns with you painting over this, even with the Dulux Precision primer. Sanding with some coarse-ish sandpaper might be needed to key the surface before priming. Potentially some 120-grit sandpaper might do the job. I'd encourage you to do a small test section, wait for the primer and paint to fully cure and try a scratch test to see how well it binds. I'd be hesitant to commit to the entire wall as, at the moment, you're painting onto an unknown surface.
