Question 1

Can I use Hammerite Direct to Rust paint without removing all the rust first?

Accepted Answer

Yes — Hammerite Direct to Rust is specifically formulated to bond over light to moderate rust without full wire-brushing. That said, you should still remove any loose, flaking, or powdery rust before applying, as the paint can't bridge unstable material. For heavily corroded surfaces with deep pitting, a full strip-back will give a more durable result. The aerosol format is particularly handy for awkward shapes like railings and hinges.

Question 2

What's the actual difference between Dulux and Dulux Trade paint?

Accepted Answer

Dulux Trade paints are formulated for professional decorators and offer notably better opacity — meaning you're more likely to achieve full coverage in one coat, especially on mid to dark shades. They also tend to have a more consistent sheen level and are available in larger tins. The trade-off is price: Dulux Trade averages significantly more per tin than the standard retail range. For a single room, standard Dulux is fine. For a full house or rental property, Trade pays for itself in time and paint saved.

Question 3

How do I know if I need a primer before painting walls?

Accepted Answer

You need a primer if you're painting onto new plaster, bare plaster, bare wood, or a surface that's been stripped back. You also need one if you're making a dramatic colour change — say, from a deep red to white. On previously painted walls in reasonable condition, a good-quality emulsion applied directly is usually sufficient. Skipping primer on new plaster is the most common decorating mistake — the plaster absorbs the first coat unevenly, leaving a patchy finish that no amount of topcoats will fully fix.

Question 4

Is it worth buying cheap house paint, or is it a false economy?

Accepted Answer

Cheap paint is almost always a false economy for walls and ceilings. Budget emulsions typically have lower pigment density, meaning you'll need three or four coats to achieve what a decent mid-range paint does in two. Factor in your time and the cost of extra tins, and the savings evaporate. The exception is genuinely low-traffic areas — a loft, a utility room, or a garage — where a budget option is perfectly adequate. For anywhere you'll actually live in, spend from 10 £ upwards and buy a known brand.

Question 5

What does VOC mean on a paint tin, and should I care?

Accepted Answer

VOC stands for Volatile Organic Compounds — the solvents that evaporate as paint dries, causing that distinctive smell. High-VOC paints (typically solvent-based gloss and metal paints) require good ventilation and can cause headaches or irritation in enclosed spaces. Water-based emulsions are generally low-VOC and safe to use in occupied rooms. If you're painting a child's bedroom, a small flat, or anywhere with limited airflow, always check the VOC rating on the tin and opt for a water-based formula where possible.

Question 6

Which finish should I choose for a hallway — matt, satin, or gloss?

Accepted Answer

Satin or eggshell is the right choice for most hallways. Matt looks beautiful but marks easily and is difficult to wipe clean — a problem in a high-traffic area. Full gloss is washable but unforgiving of surface imperfections and can feel clinical. Satin hits the middle ground: it's wipeable, reasonably durable, and forgiving enough to apply without perfect prep. Many decorators use a satin emulsion on walls and a full gloss on woodwork for exactly this reason.

Question 7

Are there any traps to watch out for when buying house paint online?

Accepted Answer

The biggest trap is buying the wrong volume — tester pots and 0.75 L tins look similar in product images but cover vastly different areas. Always check the stated coverage on the product page and calculate your square metreage first. A second common issue is colour matching: screen colours are never accurate, and even the same colour code can look different between a matt and a satin finish. Order a tester pot before committing to a large tin, especially for bold or dark shades. Finally, watch out for "was/now" pricing that inflates the original price — comparing across merchants on MagicPrices makes it easy to spot genuine discounts.
