Does Masonry Paint Need A Primer?

Whenever you are painting masonry surfaces, one of the biggest issues that can complicate the painting process is the rugged and porous texture. That is why it is almost always a necessity to use a suitable primer when painting on masonry, as this will seal the porous texture, allowing the paint to adhere to the surface, rather than being absorbed.

However, if you are using masonry paint, then you are using a paint that has been specifically formulated for use on masonry surfaces. Does this mean that you still need a primer? Or will the masonry paint alone do the trick?

The whole point of masonry paint is that it has been formulated specifically for masonry surfaces, so the paint is designed to bond much better with the rugged and porous texture, as well as being a lot more durable and resistant to exterior weather conditions such as rain and others. So technically, the use of a primer is not as important or as necessary as with other regular paints, with which you 100% have to use a special masonry primer.

Nevertheless, it is always recommended that you do use a primer, as it will better establish the adhesion of the paint on the masonry surface, and will overall add a better layer of protection and durability. Plus, a lot of masonry paints have a matching primer that is also specific to masonry and paired together they will have the most professional and long-lasting result!

Can I paint a fence with masonry paint?

Masonry paint is made specifically for use on masonry surfaces, and fences are usually made out of wood…so can you paint your fence with masonry paint? Despite the intended use of masonry paint not being for wooden fences, you can technically still use it, and it will be pretty effective.

Truth is, masonry paint is one of the best types of paint to use on exterior surfaces, as it is extremely resistant to weather conditions even before a sealer is applied. And as a wooden fence is outdoors, it needs all the protection it can get!

However, you shouldn’t always just assume that masonry paint will be fine for use on a wooden fence. Wood can expand with changes in the temperature, and it is also a lot more vulnerable to weather conditions, especially to rain, dampness, and moisture. So masonry paint might not be as ideal as it initially seems.

Instead, you should double-check whether the masonry paint you have is also suitable for exterior wooden surfaces, the label will sometimes indicate alternative uses to the one the paint is initially intended for!

And at the end of the day, although masonry paint might end up being fine, a paint specifically made for exterior wooden surfaces will be much better.

Can you add water to masonry paint?

As a general rule, it isn’t recommended that you add water to paint unless it is specifically stated that you should. After all, the paint sold by different brands will be specifically formulated and designed for certain purposes, and adding water can ruin the application and finish, meaning you won’t get the intended results, or the finish might not be as professional.

However, there are a few occasions in which adding water to masonry paint is completely fine. And in some cases, adding a bit of water to your masonry paint might also even be beneficial!

For example, adding a little bit of water to masonry paint is quite common when it comes to painting the first coat on a surface that needs sealing for the first time. Basically, many types of new render are highly absorbent, so adding a bit of water to your masonry paint will mean that the new render absorbs most of that water and diluted paint, sealing it so that the next layer of masonry paint stays on the surface with more ease, instead of also being absorbed. It means you use less paint for that initial sealing of the texture, as most of what it absorbs will be water. So it’s a great way of sealing masonry for the first time while saving a little on the amount of paint used!

Can you paint over masonry paint?

If you want to give a painted masonry piece a makeover, this might mean painting over the old masonry paint. Or in other words, it means repainting. But can you do that? As in, can you paint over masonry paint?

The answer is yes! It is completely fine to paint over masonry paint, although you first have to check the condition the old masonry paint is in, and act accordingly.

So, for example, if the old masonry paint is really old and has already started to peel or come off, then it is in no condition to be painted over. Instead, you will first have to strip the old peeling paint off, as it is not a viable surface for the new paint to adhere to. Once the paint has been stripped, and the surface has been cleaned, smoothed, and primed, then you can add the new paint without any issues.

If the masonry paint is still in good condition, then there is no need to strip or remove it, saving you that extra effort. Instead, you can simply apply a suitable primer, and then add the new paint on top.

What happens if you paint wood with masonry paint?

If you paint wood with masonry paint, chances are the paint is going to peel off and be unsuccessful, as wood is a very porous surface. Instead, you need to first apply a suitable primer for wood, and then add the masonry paint on top.

What is the best masonry paint?

There are many different types of masonry paint, which come from different brands and with different specifications. There is no single best type of masonry paint because it fully depends on the way in which you are going to use the paint and the type of masonry surface.

However, two of the most popular brands of masonry paint are Dulux, and Sandtex, both of which are highly recommended by professionals.
