Gori 99 Extreme Opaque Wood Finish is a water-based product used to coat external timber such as fascia boards, windows, doors, cladding, fences and sheds. Touch dry after an hour, recoat after 4 hours, and available online by clicking here in thousands of different colours.
The Data sheet for this product instructs a user to remove any previous paint from a surface you intend to paint, and then prime bare timber using Gori 11 Wood Preservative. Gori Extreme Opaque Wood Finish can be applied via brush and roller or airless sprayer.
My Confusion About Gori Extreme Opaque Wood Finish
I’ll start by saying I’m absolutely baffled by this product. It is manufactured by PPG, who also make all the Johnstone’s Trade products, and it’s been available for a few years. But even as a Professional Decorator, I see absolutely no evidence of this product on the normal channels. A stand just appeared in the corner of my local Johnstone’s Decorating Centre one day and it was packed with Gori paint products. However, there was none of the usual fanfare, very little information, and no advertising. It’s like PPG wanted to keep Gori paint a secret.
The other thing that confuses me is the data sheet. On one hand it says that all old paint needs to be removed before you can apply Gori Extreme Opaque Wood Finish (which seems very extreme). On the other hand, it says Gori Extreme Opaque Wood Finish is great for colour changes, “even dark colours to light colours”. You would assume any paint product is good for colour changes if you remove all the previous colour before starting? Who knows.
(After speaking with PPG, it turns out that you can apply this product over existing paint).
My Gori Extreme Opaque Wood Finish Review
Anyway, let’s get into the review. I have used Gori Extreme Opaque Wood Finish on three jobs now, and despite my confusion, I quite like it. I have used it over previously painted surfaces and bare timber in various colours.
Opacity, flow, and overall finish are all genuinely spot on. It’s durable too, making it the perfect paint for front doors or windows. Although I’d guess it is designed more for cladding and other surfaces like that (again, who knows).
One thing I will say, is although I can’t speak from experience on the longevity of Gori Extreme Opaque Wood Finish, it is packed with technology designed to keep it looking good for extended periods.
Not only is it water repellent, but it also protects against mould and fungi growth for years to come. This is due to “slow-release technology” that keeps agents in the paint film active over its lifespan. It’s got a life expectancy of 15 years, which is great for a water-based satinwood.
I can’t speak to the opacity in white, because I have only used it in tinted colours, but the paint has performed well for me so far. It absolutely flies on and looks fantastic.
Moreover, it sounds like the protection offered Gori Extreme Opaque Wood Finish exceeds any alternative products. It isn’t just waterproof, but it’s water-repellent. It doesn’t just protect against mould in the short term, but it protects over the entire lifespan of the paint. Gori Extreme Opaque Wood Finish is genuinely a good product.
This is a shed I painted recently using Gori Extreme Opaque Wood Finish. It is usually hard work to paint large flat surfaces like this with water-based products. You’re often left with brush marks, or it’s difficult to keep a wet edge.
This wasn’t the case with Gori Extreme Opaque. I found it a dream to apply, and the finish looked awesome with very little effort at all.

Hi this can be painted over previously painted I checked with technical the wording isn’t correct on the can… it says loose fibres and old paint layers need to be removed… this only applies if the paint layers are loose painting it on adhered paint with no problems is completely fine… gori can be tinted into “gori white” but not brilliant white as standard and do not use it indoors.
Hope this helps
I used this brand during Covid year as I couldn’t get my usual water based products. I found it much stickier than either the Dx, Johnno’s or Zin w/b opaques. Application, therefore, a bit slower but the finish was good. 15 year lifespans I take with a pinch of salt as there are so many variables that affect this before, during and after application.
