No, you should not use silk paint outside.
According to the provided reference, vinyl silk paint is only designed for interior use to provide a wipe-clean finish. It is not formulated to withstand the elements, such as rain, sun, and temperature changes. Therefore, using it outdoors would lead to premature failure of the paint, including cracking, peeling, and fading.
Why Silk Paint is Unsuitable for Exterior Use
-
Composition: Silk paint is typically an interior emulsion paint. This means it's designed to be breathable to prevent moisture build up in the home and is not formulated to resist the harsher conditions experienced outside.
-
Durability: The primary purpose of silk paint is to provide a wipeable surface inside, not to offer protection against the elements.
-
Weather Resistance: Silk paint lacks the necessary properties to withstand rain, UV exposure, and temperature fluctuations experienced outdoors.
What to Use Instead
Instead of silk paint, you should use exterior masonry paint for outside walls.
-
Masonry Paint: This type of paint is specifically formulated to protect exterior walls from the weather.
- It is breathable.
- It is durable and water-resistant.
- It contains UV inhibitors.
-
Pliolite-Based Masonry Paint: For superior durability and longevity, consider a pliolite-based masonry paint, although it is generally more expensive. The reference specifies that this type of masonry paint will "last for many years".
Summary
| Feature | Silk Paint | Exterior Masonry Paint |
|---|---|---|
| Intended Use | Interior walls | Exterior walls |
| Durability | Low for exterior use | High |
| Weather Resistance | Minimal | Excellent |
| Key Benefit | Wipeable finish | Weather protection |
| Example | Bedroom wall | External house wall |
In short, always use the correct paint for the job. Using the wrong type, such as silk paint outside, can be a false economy, leading to additional costs for remedial work.
