Zinsser Allcoat Exterior Satin (water-based)

By Professional Decorators

Zinsser Allcoat exterior satin water-based is suitable for interior and exterior use on many surfaces such as wood, metal, masonry, concrete, cladding and plastic. The adhesion qualities of this product are outstanding, eliminating the need for a separate primer. Zinsser Allcoat exterior satin is available in white, black or a handful of tints. The sheen level is around 40% which is standard for and satin, but this varies depending on the colour.


Zinsser Allcoat is touch dry after 30 minutes and recoatable after an hour, meaning you can easily apply multiple coats of paint in a day. Like any other water-based product, Zinsser Allcoat exterior satin does take a while to fully cure and go hard (around a week).


You can order this product from Dulux and Johnstone’s decorating centres; however, Crown decorating centre carries white and black it in stock, so if you’re in a rush you may be better going there. You can also order Zinsser Allcoat Exterior satin online from trade websites such as Paint Shed.

Zinsser Allcoat is great gear, water based, can get several coats on in a day, protects well 👍


The solvent-based alternative is great too. Bit sticky to apply, but opacity and overall finish is fanatic.

James Miles

Zinsser Allcoat sprays great. Dries fast, has good opacity and adhesion. Used it on front doors also.

I’ve only been using Zinsser Allcoat for a year or so now. I always have just a small 1 litre tin on the go. It’s my get out of jail paint, because of the built-in self-primer. Basically, if I’m repairing or replacing any woodwork, I can go straight over the top with this, then apply any waterbased paints. Hope that helps 👍🏽

Zinsser Allcoat great stuff, as mentioned above, multiple coats on in a day. It covers well and dries great. The white isn’t the best for coverage, but the black always performs well. It has the added bonus of being a primer, undercoat and topcoat in one, so you only usually need the one product instead of multiples. I went back to a job last week where I used Allcoat in black last year on some external windows and has stood up well to the elements. I would defo recommend to anybody to use. Maybe keep a bit of Floterol handy in summer as it can get quite thick in the kettle quite fast.

Excellent stuff and the rapid drying gets you out of a hole when needed.

I’ve been using Zinsser Allcoat around 3 years, in white, black & colours. I’ve never had an issue in either, except white can sometimes lack opacity, but that’s to be expected in most paints.

The only downfall I can think of is the rate it dries at can sometimes be too quick, even when temperatures are mild.

But for the most part, the opacity is great, the finish (dependant on the applicator, of course) is very good. Dries rock solid, even after an hour or less.

Sprays fantastically with little effort.

The fact it can be used on multiple surfaces, along with all the other pros, certainly must put it on the shop shelf for any job.

I’ve been using Zinsser Allcoat about 3 years now and absolutely love the stuff. It is my go to exterior paint goes on almost anything. The white does lack opacity but I get my supplier to add some white tint which helps a lot.

Richard McCafferty

Don’t think I’ll use anything other than Zinsser Allcoat for exteriors now, brilliant to work with and a few coats on in a day easily tougher than oil-based paints when dry and lovely finish, a dream to spray too,

10 out of 10 from me

Kevin Bowie - Zinsser Allcoat Exterior Satin

Great stuff though the coverage on the white is terrible you usually need about 4 coats to get it solid

Lee Quine

Used it for years great paint, white needs 3 coats to cover, but love it! The overall finish and performance is brilliant.

Paul Dorling

Zinsser Allcoat is a fantastic product. A tad expensive, but the adhesion is fantastic, you can apply it to multiple surfaces and the finish is awesome. I would highly recommend this product to anyone.

Mike Gregory

Zinsser Allcoat is one of the best water-based paints you can use on an exterior. You can use it on anything, masonry, soffit and fascia boards, doors, windows, anything! Great opacity, good flow, awesome adhesion, AND you can apply multiple coats in a day, what’s not to love??


The best thing about Zinsser Allcoat is you can rely on it. You know it’s going to last. Normally, if you’re using a water-based coating over oil, you get worried about adhesion. I’ve been using Allcoat for years now and regularly revisit jobs I’ve completed in years gone by. There are never any adhesion issues, and it always lasts well.


One thing I will say, although you can apply multiple coats of this product in a day; it takes around a week for Zinsser Allcoat to cure and toughen up. This can be a pain if you’re painting doors, because at some point they will need to be closed. Just go gentle with them for a while. Brush marks can be a pain too, as it can with any water-based satin.

Jack Murphy

One of the best exterior trade products on the market. The finish can be a little stringy, especially on a hot day. I think this is true of any water based products though. This stuff dries fast, looks fantastic and lasts for years. I would highly recommend.
