If you have been down to your local hardware store lately you will notice the myriad of options out there for exterior paints. By far one of the market leaders is Dulux with their flagship product Weathershield. Dulux Weathershield is a water based self-priming paint for exterior use and claims to gives a tough flexible finish, for long life protection all Australian weather conditions. Dulux guarantees that this product will not blister, flake or peel for as long as you are living in your house. so let’s break it down.

Dulix weathershield product review

Weathershield comes in many finishes such as matte, low sheen, semi-gloss and gloss, to find out more about which paints go wear check out THIS article. It is self-priming and tannin resistant meaning that it doesn’t necessarily require that an undercoat is applied beforehand, however common sense should be used when assessing your specific situation as this doesn’t apply to things like galvanised steel, rusted steel, water stains or unsound substrates. If you are unsure of what preparation needs to be done and when check out THIS article.

Weathershield is touch dry in around 30 minutes and re-coat is recommended after two hours in ideal condition, however longer may be need in high humidity or low temperature conditions. Once the paint is touch dry we have found that there is around a 7-day moisture sensitivity period where the coating is vulnerable to water such as heavy rain and dew or if water is allowed to sit on top of a newly coated surface. We found that Weathershield reaches its hardest point around 30 days after the final coat has been applied. Dulux Weathershield, once dry, is almost like a stretchy plastic type feel which allows it to more with the climate which help to prevent the crackling that we see in older enamel paints.

 

Application

Having been a house painter contractor for many years we have used Dulux Weathershield for many applications, substrates and situations. Weathershield is suitable for most exterior applications from gutters and fascia to weatherboards and balustrades, although Weathershield is great for many surfaces it doesn’t perform great on what we call friction areas or wear areas such as stair treads, decks, windows or doors. These areas require something slightly harder wearing as Weathershield has that 30 days full curing time and the moisture sensitivity issue. You can apply it via brush roller or spray without any dramas, you can also add up to 10 percent water to the paint in hot or dry condition to aid in application, although you should avoid adding to much water in the case of darker colours as it can create lap marks.

Longevity

We have applied Dulux Weathershield for over ten years and seldom have a problem with it other than when we have used it on friction or wear areas. Dulux claims that the Weathershield will not ‘blister, flake or peel for as long as you are living in your house’ but what does that mean exactly, if you live there for 30 years can you claim a guarantee? no exactly. Dulux give a 15 year guarantee on Weathershield which i think is a very fair deal considering that the exterior of your house does cop a flogging, especially here in Brisbane where we do most of our house painting work, and by age 15 your house would be well over due for a fresh lick of paint. There are few things you would need to do to keep your paint in good nick over those 15 years such as annual cleaning and maintenance, I mean you wouldn’t not wash your car for over a year would you?

 

Price

Weathershield is definitely up there in terms of price, expect to pay up $18 per litre from re-sellers like Bunnings so you should always seek out the closest Dulux trade outlet, but in my experience it is worth every dollar. Firstly, it is very easy to use and widely accessible from both Dulux trade centres and Hardware stores. Secondly, it is a top notch product and in my opinion the market leader for exterior paint.

 

Overall I would say that Dulux definitely deliver on their promise of quality as I still drive by and have a sticky beak at houses I have painted 10 years ago and see the same paint I put there with no defects. I will say that while Weathershield is very versatile however it’s not a one size fits all solution and you can’t have the attitude of ‘just paint over and she’ll be right because its self-priming’.
