Painting a house for success isn't about the brand you pick, it's about understanding what the paint actually does on your walls.
I've spent way too many afternoons standing in hardware stores staring at colour swatches that all look identical under fluorescent lighting. Dulux Heritage Eggshell True White is one of those paints that sounds ordinary but actually handles a lot of the things that go wrong when you're painting a room yourself. The eggshell finish sits somewhere between flat and satin, which matters more than people realise. True White isn't as aggressively bright as pure white and it doesn't have that yellow undertone that cheap whites develop after a year of living in a room. Here's how I approach a full room job with this paint. It covers roughly twelve square metres per litre across two coats on a properly prepared surface. I mix every can thoroughly, not just stir it. That pigment settles at the bottom and if you don't get it into suspension you'll end up with one patch being slightly glossier than the next. Roll on with a medium-nap roller, keep a wet edge so you're not leaving overlaps that dry differently, then go back over it lightly to even it out before the first coat sets. The second coat goes on perpendicular to the first if you can manage that geometry in a corner. Let it cure fully before you move furniture back in. I once painted a bedroom ceiling in a house that had smoke damage from years of cooking. The True White went on beautifully, covered completely, and looked fine for three weeks. Then the stains started bleeding through at the joints where the plasterboard met the wall. Eggshell has a slightly permeable film compared to satin or gloss, so it didn't block the tannin migration the way I expected. What worked was a single coat of B&Q's stain-blocking primer diluted fifty-fifty with water, rolled on lightly so it soaked in rather than sitting on top, then the two coats of Heritage Eggshell over that. Took forty minutes extra but saved me from tearing the whole ceiling down.
People often think eggshell is just "a bit shinier than matt" and that's technically true but it misses the practical part. Eggshell reflects enough light to make scuff marks visible faster than flat paint, which means you need to be honest about where you're putting it. Hallways and kitchens work fine. Rooms with kids who throw things against walls will show every bump within months. The paint itself is durable, but the finish highlights surface damage that flat would just absorb visually. Another thing that catches people out is the drying time. Dulux states two hours between coats at twenty degrees and fifty percent humidity. That's on the surface, not structural drying. If you're working in a room with poor airflow or the temperature drops below sixteen degrees, those two hours stretch to four or five. I learned that the hard way on a Victorian terrace in November. The second coat went on looking uniform and then twenty minutes later I noticed slight roller marks where the first coat hadn't actually set through. I sanded them out after twenty-four hours with 240-grit paper and reapplied. Cost me an extra hour and a can of paint but the wall looked acceptable after. True White specifically is worth discussing because "white" is not a single thing. This particular shade has a very subtle cool undertone that reads as clean in most lighting but can feel slightly clinical in rooms with no natural light. A north-facing room in London will make it look greyish by late afternoon. I'd recommend painting a large sample board and living with it for two days before committing. The colour looks different at nine in the morning versus seven in the evening and you need to see it under both conditions.
Application tools matter more than you'd expect with eggshell. Cheap rollers shed fibres into the wet paint and you spend the rest of the afternoon picking them out with tweezers. A decent microfiber roller cover in the 10mm nap range works best here. Brushes should be synthetic, not natural bristle, because natural bristle splits the paint and leaves streaks that eggshell highlights rather than hiding. I use a 50mm angled synthetic brush for cutting in and a 230mm roller for the flats. The biggest limitation of Dulux Heritage Eggshell True White is price and availability. It retails at roughly twenty-five pounds for five litres, which is mid-range but not budget. More importantly, it's not always in stock at local stores. I've had jobs where I ordered it online and it took five days to arrive, meaning I had to pause the project and do something else with whatever paint I had on hand. If you're committed to using this specific product, order it before you start decorating, not after you've peeled half the old paint off the walls. There are alternatives if you can't get your hands on it. Johnstone's Eggshell in Bright White runs about ten pounds cheaper per five litres and covers similarly, though the durability feels slightly less robust over time. Dulux's own EasyClean Matt in Pure White is a different finish entirely but costs less and masks surface imperfections better than eggshell ever will. If your walls are in poor condition, skip eggshell altogether and go for a quality matt. The paint won't fix bad plaster, and eggshell will show you every mistake the plasterer made.

Preparation is where most people fail regardless of what paint they buy. Clean the walls with sugar soap, fill any cracks with a flexible filler, sand smooth when dry, and vacuum the dust off before priming or painting. Skip the cleaning and the paint adhesive fails at the microscopic level. You won't notice it until six months later when a patch starts peeling and you have no idea why. I've seen it happen with the most expensive paint money can buy. If you're painting a whole house room by room, plan your schedule around the curing time. Each coat needs at least four hours before you can handle it and twenty-four hours before normal use. Two coats minimum for coverage on a previously painted surface, three if you're going from a dark colour to True White or covering a textured finish that absorbs paint unevenly. Budget roughly forty-five minutes per square metre including setup, cutting in, rolling, and cleanup if you're working alone at a normal pace. A standard ten-square-metre bedroom takes about seven to eight hours from start to finish with two coats.
