SOLVED: Can You Water Down Masonry Paint?

Painting a house can feel like a gargantuan feat, especially when you’re new to painting. If it’s your first time painting an exterior, then you’re bound to have a few questions. 

One common question that might arise is ‘can you water down masonry paint?’. Knowing where you stand with masonry paint and water can mean all the difference between a good finish and a bad finish, as well as determining just how many times you’ll have to paint your home. 

Before you jump into your exterior painting project, here’s everything that you need to know about water and masonry paint…

Masonry Paint and Water: Is It a Good Combination?

Running out of paint can be an absolute nightmare, particularly when you’re fighting against the clock and are trying to get the perfect finish. It can be all too tempting to add a little water to your masonry paint to make it stretch further, but is it the right thing to do?

Adding water to masonry paint is something to definitely avoid if you’re just trying to make the paint stretch, as it’s not going to deliver the same kind of finish as undiluted paint. This is especially the case if you’ve already started painting the current layer.

However, that’s not to say that there is an occasion where it’s okay to add water to your masonry paint…

Adding too much water to your paint or buying paint with a high-water content could mean that you have to add a lot of coats to your wall to get the desired finish – and probably burn through a lot of paint in the process!

When Can Water Be Added to Masonry Paint?

Many paint brands will strongly advise against adding water to their paint if you’re after the best finish, but for some applications there is no harm in adding a small amount of water to certain types of masonry paint – in fact, adding a little water can be a benefit.

A common reason water is added to masonry paint is to dilute the paint for the first coat. If you’re looking to seal a surface for the first time, then adding a small quantity of water to the paint can be quite important.

This is especially the case when painting new render. Some types of render will absorb water, so adding a little water to the paint can help to prime the render and prepare your walls for painting.

You can also add water to paint in a very small quantity for some normal applications and for application via spray. For spray applications, quite a bit of water is normally required to enable the paint to work effectively with the spray. 

It’s important to remember that not all paints are designed for water to be added, so checking the tin and researching the paint is essential if you want to avoid ruining the paint or getting a bad finish on your exterior walls.

Water in Masonry Paint: Watch Out for Poor-Quality Products

Whilst water in paint is not necessarily a bad thing and most masonry paints have some water content as standard, too much water in paint can be detrimental to the finish on your walls.

Cheap masonry paint often has a high quantity of water, which means that when the paint dries, the layer of paint is likely to be very thin, as the water evaporates.

Protecting Your Walls from Water: What To Do

While adding a little water to your paint at some stages of painting is okay, you definitely don’t want it being absorbed by your walls all the time. A damp wall has a high thermal conductivity, which means that all the heat inside your home can leave through the walls more easily.
