What You'll Learn
Painting Azek: yes or no?
Azek is a PVC product that is impervious to moisture and insects. It is a popular choice for exterior trim because it does not require painting. However, many homeowners are surprised to find that their homes look like they need to be painted a couple of years later.
While Azek does not require painting, it is highly recommended. Painting Azek helps seal up the Azek to prevent mildew from forming on the edge and end grain cuts. It also helps seal up the porosity of the material, making it much more washable than untreated Azek. Dirt, smudges, and other blemishes will wash off much easier.
If you choose to paint Azek, it is important to use the right kind of paint. Azek recommends using 100% acrylic latex paint with a Light Reflective Value (LRV) of 55 or higher. For darker colors (LRV of 54 or lower), paints specifically designed for use on vinyl/PVC products, such as Sherwin-Williams VinylSafe™ coatings, should be used. These paints are designed to reduce excessive heat gain. It is also important to ensure that the Azek surface is clean, dry, and free of any foreign material such as dirt, oil, or grease before painting.
Some people have reported issues with paint not sticking to Azek. This could be due to a lack of adhesion or surface contamination. It is important to clean the Azek surface thoroughly before painting and to use a primer if necessary. Some people recommend using a bonding primer like Zinsser's 1-2-3 before top coating.
In conclusion, while painting Azek is not necessary, it is highly recommended to improve the aesthetics and protect the material from dirt, smudges, handprints, mold, and mildew. It is important to use the right kind of paint and prepare the surface properly to ensure that the paint adheres well and lasts for years.

Recommended paints for Azek
Painting Azek is recommended for a number of reasons. Firstly, Azek is a PVC product that is only available in white, so painting it can allow for a wider range of colours and sheens. Painting Azek can also help seal the material, preventing mildew from forming on the edge and end grain cuts. Additionally, painted Azek is much more washable than untreated Azek, making it easier to clean.
When selecting a paint for Azek, it is important to choose a paint that will properly adhere to the surface. While some sources recommend priming Azek before painting, others suggest that this is unnecessary and may even cause issues with adhesion. It is recommended to use a paint with an LRV (Light Reflective Value) of 55 or higher to prevent warping, especially if using a darker colour. The paint should be 100% acrylic latex with no primer needed. One paint that meets these requirements is the Moor line of exterior finish by Ben Moore, which has been successful in adhering to PVC railings. Another recommended paint for exterior Azek trim is AquaSurTech Aqua DIY, a special reflective paint designed for colours with an LRV under 55.
It is important to properly prepare the surface before painting Azek. The surface should be cleaned and wiped down with denatured alcohol to remove any dust or grime. Additionally, it is recommended to fill any nail holes and caulk the joints before painting. It is also suggested to do a sample area and test for adhesion before painting the entire surface.

Priming: yes or no?
There is conflicting advice online about whether or not to prime AZEK before painting it. Some sources state that priming is unnecessary, while others recommend it for the best results. AZEK itself does not mention priming in its official literature. However, it is recommended that you always clean the AZEK surface before painting to ensure there is no dust, dirt, oil, grease, or other contaminants that may hinder adhesion.
AZEK is a PVC product that is impervious to moisture and insects. It does not require painting, but it is highly recommended to do so to improve its appearance and protect it from dirt, smudges, handprints, mould, and mildew. Painting AZEK also helps to seal up the material, making it much more washable and protecting it from moisture.
If you choose to prime your AZEK before painting, it is recommended to use a bonding primer like Zinsser's 1-2-3. When it comes to paint, use 100% acrylic latex paint with a Light Reflective Value (LRV) of 55 or higher. For darker colours, use paints specifically designed for vinyl/PVC products, such as Sherwin-Williams VinylSafe™ coatings, to reduce excessive heat gain.
It is important to note that AZEK trim may require additional preparation, such as filling nail holes and caulking joints. Properly preparing and painting AZEK trim can give it the appearance of finely painted wood, and a properly painted finish will last for years, protecting the substrate from mould, mildew, and UV rays.

Painting Azek before installation
Before painting, it is crucial to fill any nail holes and caulk the joints to create a smooth and even surface. This can be done using filler, caulk, and glue specified by Azek. It is also recommended to sand the surface to remove any gloss and create a better adhesion for the paint. Once the surface is properly prepared, it is ready for painting. It is important to follow the paint manufacturer's recommendations for use and compatibility with Azek.
While it is possible to paint Azek before installation, it is important to weigh the benefits against the potential challenges. Painting can be time-consuming, especially if priming is required. It may also be more difficult to achieve a consistent finish when painting before installation, as the pieces may need to be handled more during the installation process, leading to smudges or imperfections. In addition, if the Azek is not properly prepared or the wrong type of paint is used, the paint may not adhere properly, resulting in bubbling or peeling.
Overall, painting Azek before installation can be a great option to enhance the appearance and protection of the material, but it requires careful preparation and the use of appropriate paints to ensure a successful outcome.

Painting contractors
To win work, painting contractors typically have to bid against other contractors and provide a detailed description of their services. This involves estimating the time and materials required, measuring the area to be painted, and discussing the desired finish with the customer. They must also assess the quality of the surfaces to determine the necessary surface preparation, such as filling cracks or holes, removing old paint, and applying primer.
To become a painting contractor, individuals typically learn their trade on the job or through an apprenticeship. Some new workers enter training programs offered by the hiring contractor, and there are also certification programs available through organizations like NACE International Institute or the Society for Protective Coatings. These programs can lead to certifications in industrial painting or protective coating specializations.
Overall, painting contractors play a crucial role in maintaining and enhancing the appearance of various structures through their knowledge of painting techniques, materials, and tools. They must possess strong attention to detail, time management skills, and the ability to work independently or as part of a team.
