 4Dulux or Johnstone’s Paint, which is Better?

By Mike Gregory


PPG, who own Johnstone’s Paint, are the biggest coatings manufacturer in the world and a favourite with decorators. Dulux is widely known as the best paint brand amongst homeowners, but which is better in reality, Dulux or Johnstone’s paint?


In this blog I’m going to take you through some of the more mainstream TRADE  products from each brand and compare them with each other. I’ll base everything on my own experiance. There are a lot of differences in performance and I think you’ll find it useful when choosing between Dulux and Johnstone’s paint.


If you have a trade account with Dulux or Johnstone’s, it is often better going direct to buy your paint. If you do not have a trade account, it is almost definitely cheaper buying trade paint online. A good trade website I have found is the Paintshed, where not only do they sell paint products at a reasonable price, but they’ve also got everything you could possibly need to carry out any DIY project. As you’ll see from my blog, some products are better from Dulux, some from Johnstone’s. Using a proper trade website like the Paintshed means you can buy either. I have done a whole blog on where to buy trade paint from which you can see by CLICKING HERE.



Johnstone’s Jonmatt Vs Dulux Supermatt


I thought we’d start with contract matt as it’s often the first paint to be used on a project. Both these products are generally used to prime bare plaster, finish on a ceiling, or a “builders’ finish” on a newbuild.


Johnstone’s Jonmatt is a very strange paint. Opacity is unbelievable and you can easily cover bare plaster in two coats. The issue I have with Jonmatt is it dries way too fast and if you don’t keep a wet edge you will notice flashing. It doesn’t touch up either so it’s useless on a building site. If someone marks a wall or ceiling, then you’re painting the whole thing again I’m afraid.


Dulux Supermatt on the other hand is outstanding all-round. Opacity is great, no flashing or picture framing and a nice flat matt finish. A lot easier to work with than Jonmatt too. Dulux Supermatt is by far the better product, although it is slightly more expensive.

Johnstone’s 0 – 1 Dulux



Johnstone’s Covaplus Vs Dulux Vinyl Matt


Ok, let’s do vinyl matt emulsion next, and this one is a very easy choice. Johnstone’s Covaplus in my opinion is thestandard best trade emulsion on the market. It dries flat and you have very few issues will roller and brush marks. You can pay big bucks for something that performs even better, but Johnstone’s Covaplus is generally fine. Dulux vinyl matt has improved in recent years, but it still isn’t as good as Covaplus! It is expensive, has a high sheen level and roller or brush marks can be a big problem.

Johnstone’s 1 – 1 Dulux



Johnstone’s Durable Acrylic Vs Dulux Diamond Matt


Another landslide in Johnstone’s favour, although it is more to do with how poorly Dulux Diamond Matt performs, rather than how good Johnstone’s Durable is. Dulux Diamond matt has an issue with it’s sheen level, meaning its closer to a soft sheen than a matt. This effects the overall finish in a negative way. You can still achieve a good finish with it, but it definitely lags behind the Johnstone’s Durable and Crown Clean Extreme.

Johnstone’s 2 – 1 Dulux



Johnstone’s Satinwood Vs Dulux Satinwood


Both of these products have great opacity and are lovely to apply. I’d say the Dulux leaves a slightly nicer finish. The real test for quality oil-based paint in white nowadays is how long it will stay white for. This is down to the VOC restrictions, but that is another blog entirely. Johnstone’s oil-based Satinwood does not last very long at all before it starts to yellow, whereas the Dulux can look brand new for years. Go for the Dulux Satinwood every time.

Johnstone’s 2 – 2 Dulux



Johnstone’s Aqua Guard Vs Dulux Diamond Satinwood


AHHH!!! Water-based satinwood!! Dulux Diamond Satinwood is fully water-based and leaves a spectacular finish. It is quick and easy to apply, but you need to keep going over your work because it sags and runs. This can make your overall experience a nightmare!


Johnstone’s Aqua Guard is another level. You need to ensure you use the correct undercoat to adhere to previously painted surfaces. This is a fully water-based paint which is easy to use and leaves a fantastic finish. The opacity and finish are far better than that of the Dulux Diamond.


This Definity swings in Johnstone’s favour, although they are both good products.

Johnstone’s 3 – 2 Dulux

Johnstone’s Trade Gloss Vs Dulux Trade Gloss (oil-based)


Not loads of people use oil-based indoors gloss nowadays, simply because of the issue with yellowing. As a decorator I try to point my clients in a different direction. That said, some people still prefer gloss over other finishes, so let’s do the comparison.


Dulux Trade gloss is sticky and hard to apply. It can creep onto another surface after you’ve cut in with it, but the finish is lovely. You need to give this product natural light as it cures, so don’t put furniture back for a few days after you’ve painted. Johnstone’s is easier to use, leaves an equally good finish, but starts to yellow within weeks of applying it. For this reason, I’ve got to go with Dulux. However, neither are great gloss products.

Johnstone’s 3 – Dulux 3

Johnstone’s Stormshield Vs Dulux Weathershield


I thought I’d cover all the exterior products for both brands in one paragraph, because it’s a landslide for Dulux at almost every turn.

Dulux Weathershield exterior gloss leaves a stunning sheen and finish. This product stays looking brand-new for years.

Dulux water-based masonry paint not only leaves a great finish, but it is cheap and easier to use than Johnstone’s stormshield, which feels more like an emulsion to apply.

Dulux also own Sikkens, so they have stain covered too. Plus, they have a great exterior water-based gloss which can look fantastic.


The only downside about Dulux Wethershield is they have discontinued their pliolite-based masonry paint, which is a real shame. Johnstone’s Pliolite-based masonry paint is an awesome product.


I’m giving this one to Dulux. Johnstone’s 3 – 4 Dulux


Choice and Product Range


This is an easy one! Johnstone’s have a product for everything! They have 3 different variations of durable matt, so you can choose just how durable you want it. They also have a water-based stain block and finish coat in one called “stainaway”. They’ve got a premium matt emulsion called “perfect matt” which knocks the spots off any designer emulsion out there. The list goes on and Dulux don’t have any of it. If you were going to stick to one brand for all your decorating needs, the Johnstone’s has to be the one.

What do Other Decorators Think?

Dulux and Armstead is all I use unless client stipulates otherwise. It’s great gear although I must admit been looking at cheaper alternatives recently

Ross Paton

Johnstone’s should get another point because of the huge difference in price. This compares products but the difference in cost is a joke.

Dean Young

When the lock down started, I had a completely empty refurb to work on for a landlord. Before I bought a load of materials, I thought I’d use up everything that I had in stock- Johnstone’s, Dulux Trade and Armstead- all magnolia and white. The Dulux Trade pissed all over the other 2 in terms of opacity, no contest. Much more depth to the finish. I always knew that was the case, but it was the first time I’d used them side by side.

Dan Ezard

 Quality varies too much with Dulux. Sometimes the trade paint is thinner and worse than the retail paint, sometimes it’s so thick it’s painful to use. In my opinion Johnstone is always reliable…..

Mark Byatt

Prefer Dulux emulsion, but the price is a bit high, especially when the customer can pick up 3for2 in Homebase (although inferior) Johnstone’s more reasonably priced. Prefer Johnstone’s waterbased gloss/undercoat. But you can’t beat Dulux Weathershield for exteriors.

Steve Coventry

No one company is better than another overall.

One product may be crap from one, but great from another. Whereas it could be the same scenario but the opposite way round on another product.

Then add into the mix constant reformulation of products mean what’s crap this year may be great next…. Or the other way around.

Similarly, you may have great staff in one store but another of the same brand may be poor.

My point is simply it’s the individual products that should be rated and I make no secret to them that I also use their competitors…

Ste Hanson - Dulux or Johnstone’s Paint, which is Better?

I think it varies in which product you use, as Johnstone’s aqua satin is better than the Dulux version but Dulux super Matt is better than the Johnstone’s emulsion

George W Irvine

They’re both very good brands of paint. Both have good variety in different paint types for all sort of substrates, within the commercial or domestic sector. Johnstone’s is well priced, covers well. They also match F&B colours which is something Dulux don’t do as good. However, there isn’t a paint on the market that covers better than Dulux in terms of opacity, in any form of paint. This is why you pay more for it it will cover in two no question. Therefore, Dulux edges it for me but I like both

James Miles

Only ever used Johnstone’s retail which I didn’t rate. I use Dulux the majority of the time, but I think the vinyl matt is problematic it flashes and grins a lot. I tend to stick with the diamond which I think is decent but it’s potent. Interested to hear what Johnstone’s trade is like from fellows
