Zinsser AllWeather Masonry Paint Review

Posted Aug 12, 2023 | Product Reviews, Paints | 1 comment

Zinsser AllWeather Masonry Paint is a pliolite oil-based coating designed for use on exterior masonry such as stone windowsills, render walls, copings, and brick. Available online in many colours, including white and black.

Zinsser AllWeather Masonry Paint is touch dry after around 1 hour, and recoatable after 3. However, it takes up to 7 days to fully cure and harden. The finish once cured is a flat matt. Clean up and dilute with white spirit.

You might opt for pliolite masonry paint when working in challenging weather conditions, or you’re painting a property close to the sea and need extra protection. Pliolite blocks stains too, so there is an argument for using it to paint garden walls and sandstone windowsills.

With products like this being dry after an hour, you’re protected against sudden downpours. Oil-based is generally more resilient against the elements over prolonged periods too. However, pliolite does take a little bit longer to apply, and it isn’t very nice when you get it on your skin.


My Zinsser AllWeather Masonry Paint Review


I’m now going to get into my personal opinion on Zinsser AllWeather Masonry Paint and compare it to the other pliolite masonry paint products I have used in my 21 years as a Painter and Decorator.


Zinsser AllWeather seems quite thin, making it easy to use. However, even though it is thin, opacity is brilliant. This means you need to apply less coats in order to achieve a solid finish. You can even dilute it slightly to make it even easier to apply, and the opacity is still fantastic.

Another plus point for the ease of use is the recoat time. A lot of other plioltite based masonry paints take 16 hours before you can apply additional coats, but as Zinsser AllWeather Masonry Paint can be painted over after 3 hours, you can easily apply 2 coats in a day.

The finish looks fantastic, it’s durable, and it seems to go further than comparable products. You’d expect it to be quite expensive because it performs like a premium product. If buying Zinsser AllWeather Masonry Paint online, then it really isn’t too bad. It’s roughly the same price as the other trade brands.

I thought I’d include a picture of a job we recently worked on using Zinsser AllWeather. The sandstone windowsills on this house held a little bit of moisture, so we needed a pliolite based masonry paint to block any stains. The house is in a seaside town, so we needed something that would withstand the salty air. We also needed the paint to remain breathable, so the moisture didn’t get trapped.

Zinsser AllWeather Masonry Pant ticked all the boxes. Plus, because it’s easier to work with than other pliolite masonry paints, it made cutting sharp lines a dream. It really was the perfect product for the job. Not only that, but we only used 4L of paint on the whole project!

Final Thoughts


I’m relatively new to using Zinsser AllWeather Masonry Paint, so I can’t comment on its longevity, but I’m genuinely impressed by its performance. You often think of Zinsser as ‘problem solving products’, but with products like this one, their AllClean Durable Matt, and AllCoat, maybe it’s time to acknowledge them for their finishing products. I challenge anyone to name a Zinsser product that doesn’t perform well.

    Will give this a whirl.

    Oil based masonry are generally a complete pain to use , takes longer than water and soft finish .

    The Dulux trade all seasons was the best but discontinued.

    Good to hear, and handy with UK climate short recoat times.
