Do you need a primer / Undercoat?

Whether you need a primer or undercoat will depend on the surface you are adding masonry paint too.

If you are painting over existing paint, you should be able to apply directly over original coats, without any kind of undercoat or primer.

If you are painting on to clean, unpainted brickwork, render or pebble dash, you should also be able to paint straight on to the walls without a primer. These surfaces will generally need between 2-3 coats.

It is advised that you add a thinned coat of the masonry paint as your first coat, this can be thinned by adding a small amount of water to your masonry paint.

The water can help to prime the surface ready for painting. The reason for this, is some surfaces will absorb quite a lot of water on their first coat. This is particularly true for things such as new unpainted render.

Occasionally, if the surface you are painting is loose or powdery, you may need to use a primer. However, it is important to remember that masonry paint is formulated to be breathable. Adding a primer could impede this process and cause the walls to sweat.

Ideally a primer should only be used if absolutely necessary.

Prepping walls before Painting

Before you start painting, it is extremely important that you put a good amount of time and effort, into preparing the surface.

The amount of preparation will show in the finished result. It could also affect the life of your masonry paint. Generally, these types of paint will last 10-15 years before they need repainting. Poor preparation of the surface could drastically reduce this number.

Not only that, but poor preparation could have a detrimental effect on the quality of finish you get.

Firstly, you should ensure that the surface is completely clean. This will involve brushing away all loose debris, dust, and dirt. This will likely include washing down all the surfaces.

You should also make sure that all cracks and holes are filled correctly and any loose material around these cracks is removed. You don’t want to be painting onto any loose surfaces.

For any areas of render or pebble dash, that are powdery, or crumbling. You may need to remove and patch these areas before you apply your masonry paint.

The goal here is to have a clean, smooth, defect free surface. The surface you are painting onto, should reflect how you want the finished job to look. If you don’t address these things before painting, they will be noticeable once the job is complete.


in our opinion, the paints listed above are the best exterior masonry paints on the market right now. Dulux Weather Shield is our first choice you can check it out here. It is slightly more expensive, but for the small increase in price, it is well worth the high quality of finish you will receive.

With that said, all the masonry paints listed above are very high quality. Any of these paints will help you to achieve a high quality finish on the exterior of your property. Exterior masonry paints are a fantastic way of damp proofing your property. As well as adding additional insulation, and an aesthetically pleasing finish to the outside of your building.
