Material Properties
UPVC Composition: UPVC (Unplasticized Polyvinyl Chloride) is a type of plastic that is durable and weather-resistant, making it a popular choice for doors and windows. However, its smooth surface can make it challenging for paint to adhere properly without proper preparation.
Thermal Expansion: UPVC expands and contracts with temperature changes. Therefore, the paint used must accommodate this movement to prevent peeling or cracking.
Choosing the Right Paint
Type of Paint: Use specifically formulated UPVC paints or high-quality weatherproof acrylic paints. Brands like Zinsser AllCoat and Rust-Oleum are recommended for their adhesion properties and durability.
Finish Options: Available finishes include matt, satin, and gloss. The choice depends on your aesthetic preference and the desired level of sheen.
Preparation Steps
Cleaning: Thoroughly clean the UPVC surface with soapy water to remove dirt and grease.
Sanding: Lightly sand the surface using fine sandpaper (240-320 grit) to create a rough texture that helps the paint adhere better.
Masking: Apply masking tape to areas you do not want to paint, such as glass or adjacent surfaces.

Application Process
Temperature: Ensure the temperature is above 5°C during application to facilitate drying.
Coats: Apply at least three coats of paint, allowing adequate drying time between each coat (usually around 30 minutes) to ensure even coverage.
Drying Time: Allow the paint to cure fully for at least 24 hours before handling or reassembling any fixtures.
Longevity of Paint
Using high-quality UPVC paint can provide a lifespan of over 10 years, with some products offering warranties up to 15 years against peeling and fading.
Color Options
You have a wide range of colors available, including popular choices like anthracite grey (RAL 7016) and sage green, allowing for customization that enhances your property’s curb appeal.
