SHORT ANSWER - Dulux is very good. Taubmans is as good and a tiny bit cheaper.
LONG ANSWER - Most people assume that there is a 'best' paint to use when painting your home's interior. And because they see it advertised more, people often think of Dulux.
All paints have different qualities for different situations (hardness, stretchiness, sun resistance, mould resistance, fade resistance etc.) Or put another way, Horses for Courses.
For now, I'll stick to writing about interior wall paint and leave ceiling paint and trim paint for another time!
Choice has recently tested 24 interior wall paint options (available for $5 from their website). They tested 4 attributes: Hiding power, Stain resistance, Scrubbing resistance and Cost.
The top 3 place getters are Resene Zylone Sheen, Dulux Wash and Wear Plus Superhide Low Sheen and Taubmans Endure.
All 3 are premium paints with good Hiding power, Stain resistance, Scrubbing resistance. Not surprisingly they are also on the expensive end of the spectrum.
Each of the top 3 has a particular strength. Resene has the best 'scrubability'. Dulux the best 'stain resistance' and Taubmans the best compromise on all attributes.
These 'scientific' findings are interesting to me. I've found Dulux and Taubmans to both give great finished results, but have quite different 'feel' when painting. Dulux is 'thick' and 'gluggy' whereas Taubmans is 'runnier' but still covers well.
But Choice tells me that Taubmans has better scrubability than Dulux, which I think is important for a long lasting paint job.
So my gradual move from Dulux to Taubmans now has science to back my gut feel!
(And if you were thinking that the other cheaper paints were either rubbish or pretty much the same, you'd be wrong on both counts. The rest of the paints they tested had lower prices and decent hiding and stain resistance BUT really fell apart on scrubbing resistance. So if you want to wipe marks off your walls without wiping the paint too, don't buy cheap paint!)
I've been drawing and painting since I was a kid. I've studied art and design and have worked in visual areas my whole life. Now I'm a house painter!
