Masonry paint is a great choice of paint for exterior walls.
They are (predominantly) acrylic based paints specifically designed to easily adhere to even coarse and difficult surfaces, and are perfect for painting over a wide range of surfaces including natural stone, brick, concrete, or pebble dashing.
And they have a level of weather resistance that other paints simply cannot compete with.

Best Exterior Masonry Paint – Buyer’s Guide
We ask for a lot from exterior house paint, expecting it to hold out against freezing winters, soaking British rains and day after day of UV radiation. And we want it to do all this without cracking, peeling or fading.
There’s a lot that goes into making this happen. The paint needs to be packed with high-quality resins (or binders), pigments, solvents, and additives. Let’s walk you through these components.
Components of Exterior Masonry Paint
Pigments, be they mineral or man made, are what give the paint it’s colour, in terms of its hue and opacity. Binders are the resins within the paint which coalesce to form the paint film. Solvents are the liquids which help to keep the pigments and binders in suspension. And finally, you get the additives, which can have a range of purposes, such as controlling the drying time, help with leveling, and prevention of mildew build up.
The sheen of a paint, is a description of the degree of light reflection a paint has. More often than not, the less sheen a paint has, the less stain resistant it is. They range from gloss which is the shiniest, to satin which is in the middle, through to matt, on the opposite end of the spectrum which has no shine to it.
Types of Masonry Paint
There are generally 2 main types of masonry paint, smooth and textured.
Smooth Masonry Paint
What finish you get from a smooth masonry paint depends on what the manufacturer has to offer. It is possible to get the full spectrum of finishes, such as gloss, satin and matt. Whichever you finish you go for, it should feel about as smooth as interior paint when finished. This type of masonry paint is best for tackling problematic surfaces such as pebble dash.
Textured Masonry Paint
Whilst textured masonry paint is not nearly as smooth as it’s counterpart, it does come with it’s fair share of advantages. It is more weather resistant, and offers more protection from harsher climates, and from high levels of pollution. It’s also handy for sealing up fine cracks.
If you have identified textured masonry paint as the type for you, we would recommend our Number 2 product, Wethertex HBS Flex-Coat Hi-Build Coating, Heavily Textured Masonry Paint.
Characteristics of Good Quality Exterior Masonry Paint
What we mean by hiding power is the ability of a paint to successfully cover and conceal the surface on which it is applied. This comes down to 2 main factors – the paint’s pigment, and how thickly it is applied, or how many layers of paint.
Blister resistance refers to the paint’s ability to keep excessive moisture from coming through the substrate and upsetting the paint layer, causing it to “blister”. Blistering is more likely to happen when paint is applied to a damp or wet surface.
After endless debate of what colour to go for, you want that colour to remain exactly as it was when you first painted it. That’s where colour retention comes in – the paint’s resistant to fade brought about by the sun.
Frequently Asked Questions
Is Masonry Paint Waterproof?
External masonry paint, such as those in our Top 5 product, is designed to withstand the weather, including against the heaviest of rains. However, we’re going to level with you here – if your property is prone to flooding, then it is possible that your masonry paint will suffer some kind of damage and start to flake away or become soft.
But, rest assured, there are ways to prevent this. Applying a primer, for example is a great help, or you can apply a sealant. Both primers and sealants are available on Amazon.
Should I use latex based paint?
If you’ve been wondering what paint is best to use for your exteriors, we feel your pain. There are many different types of exterior paint out there, water based, oil based, acrylic based or latex based. Each type of paint has its advantages and its disadvantages.
Latex based paint dries fast, is easier to clean, doesn’t yellow over time, and is generally better for the environment. However, it will bubble and peel if applied over existing oil-based paint, and when going from a dark color to a lighter color, extra coats may be necessary.
Do you need primer for masonry paint?
On most unpainted exterior surfaces, the standard procedure calls for a primer coat followed by two topcoats of paint.
Because it has a glue-like base, a primer really helps the paint adhere properly. If you skip priming, you risk the paint peeling, especially in more humid conditions.
There can be exceptions to the rule of always applying a primer, and this includes when you’re going over a previously painted surface. Other exceptions include when you’re applying paint to fresh mortar, or when you’re using textured masonry paint to fill small cracks.
If you have any doubts over this, our advice is to always apply a primer.
How do I make my exterior paint job last?
There are several ways to make your exterior job last before you even pick up a brush or roller. First, be sure to Fix indoor moisture problems that can lead to outdoor paint trouble. This can be easily accomplished by fitting vents in moisture ridden areas such as kitchens and bathrooms. Then repair any damaged surfaces. Make sure the said surfaces are clean. Then scrape and sand the surfaces to remove damaged paint and any rough edges.
And it is only after the above steps are complete, that you can apply your primer. In many cases the primer can serve as the basecoat, so you won’t need as many coats of paint.
Then you can apply your paint – but it has to be applied correctly. The thickness of the layers of paint can make a dramatic difference to how long your paint job will last. If it’s put on too thinly, the dried paint will be weak. If the paint is applied to thickly on the other hand, it will sag and it will crack. The optimum thickness is about 4-5mm when wet. That’s about the thickness of your typical printer paper.
What does it mean if a paint is breathable?
A breathable paint is one which has special microporous characteristics that can allow water vapour to permeate through. So a breathable wall is one that will take in moisture in the air then release it, kind of as if the wall is breathing. This is important for avoiding damp and all of its associated problems. Paints that are not breathable and can trap moisture beneath the surface, which in turn can cause mould build up, or can sometimes even cause the paint to blow off entirely.
What is the longest lasting exterior paint?
Most exterior masonry paint will last a minimum of 10 years, if not 12 or 15. If you’re specifically looking for an exterior masonry paint will last a long time, we would recommend that you go for our Number 2 product, Wethertex HBS Flex-Coat Hi-Build Coating, Heavily Textured Masonry Paint.
