Spraying Sandtex Masonry Paint

So, in order to get to the bottom of this question, I will be doing some spray painting using sandtex masonry paint and seeing how well it works. Let’s have a go and see what happens!

Above you can see the breeze block wall that I will be painting for this test. This is the exact kind of surface you might want to spray with masonry paint as it can be quite tough to get paints into all the nooks and crannies.

This is the spray gun I will be using for the test, it is a gun that runs off an air compressor. There are also more domestic handheld electric sprayers you can get that don’t need a compressor but for the purpose of this test, this is what I will be using.

Before spraying we will need to thin the paint down. because the Sandtex masonry paint I am using is water-based I can do this by just adding a little water to the paint. Nice and simple.

To start with a got a bucket of Masonry Paint, SandTex Smooth White, and watered it down quite significantly. The ratio was roughly 2:1, 2 parts paint to one part water.

So now the paint is thinned it is time to spray! I have added a little video below of me spraying the Sandtex masonry paint.

And here we can see the finished wall after a single coat of paint.

So, can you spray Sandtex masonry paint?

As you can see from my testing, yes you can spray sandtex masonry paint. Not only can you spray Sandtex masonry paint it is actually really simple and straightforward to do.

Why Use Masonry Paint?

One of the main uses for masonry paint is simply decorative. Probably the most common use is painting the exterior of homes to give them a fresh appearance, just like you would with walls inside your home.

There doesn’t have to be any special reason to paint the exterior of your house with masonry paint, although it does have lots of benefits, other than just waiting to change the look.

Killing Mould And Algae

One use of masonry paint that not everyone will be familiar with is that most masonry paints actually kill mould and algae and stop it from growing on the outside of the paint.

This is because they almost always contain a fungicide and herbicide to kill this growth. This is also what makes them unsuitable for use on the inside of homes.

Water Barrier

Masonry paints are nearly always waterproof, in fact, if the one that you are buying isn’t waterproof then I would consider swapping it out for one that is.

Waterproofing brick and stone can be a great way to prevent leaks from troublesome areas. Some stone and brick are actually not that watertight, counter to what you may think.

In areas where it is constantly battered by water, either due to being in an exposed location or having a faulty drain drip on it, it can start to penetrate and enter your home.
This can lead to damp patches on walls that just won’t seem to budge or in some circumstances full-on watermarks all over your walls.

Dirt Resistance

A lot of the more popular masonry paints also include some dirt resistance. What this means is that dirt is much less likely to stick to the paint as it is to the bare masonry.

This can mean the exterior of your home can look a lot fresher and cleaner for longer. This can be particularly important for people who live near busy roads where the dirt from passing traffic can soon have masonry looking dirty and tired.
