Do acrylic outdoor whirlpool hot tubs fade easily?

Outdoor whirlpool hot tubs, as a high-end leisure amenity, have become a fixture in many homes, resorts, and hotels. Acrylic outdoor whirlpools, in particular, are highly sought after for their attractive appearance and durability. However, many people wonder after purchasing an acrylic outdoor whirlpool hot tub: Do acrylic outdoor whirlpool hot tubs fade easily? Will the color of this material change due to factors such as long-term exposure to sunlight and frequent use?

This article will delve into this issue to help consumers better understand the fading problem of acrylic outdoor whirlpool hot tubs and how to extend their lifespan and maintain their beauty.

Acrylic Hot Tubs - Everything You Need to Know

1. What is Acrylic?

Acrylic is a transparent plastic material, also known as polymethyl methacrylate (PMMA). It possesses many unique properties, including excellent clarity, UV resistance, impact resistance, ease of processing, and a long service life. Therefore, acrylic has found widespread application in many fields, including automotive, construction, medical devices, and household products. In particular, in outdoor whirlpool hot tubs, acrylic, due to its high transparency and excellent visual quality, is an ideal material for tub shells.

2. Application of Acrylic in Outdoor Whirlpool Hot Tubs

Acrylic outdoor whirlpool hot tubs are typically made of high-quality acrylic. This material not only offers an outstanding appearance but also withstands high water pressure and temperature while maintaining structural stability. Due to its glossy finish and transparency, acrylic bathtubs often appear more modern and luxurious, blending seamlessly with any outdoor environment and enhancing the overall aesthetic.

What are the causes of acrylic hot tub fading?

1. Ultraviolet (UV) Exposure

Acrylic outdoor whirlpool hot tubs are frequently exposed to sunlight, and UV radiation is a major cause of fading. UV rays cause a chemical reaction on the acrylic surface, gradually breaking down the molecular structure of the material, resulting in color fading. Ultraviolet radiation can significantly affect acrylic, especially when exposed to strong sunlight for extended periods, causing it to gradually fade or yellow.

2. Oxidation

In addition to ultraviolet radiation, oxygen is also a significant factor in acrylic fading. Prolonged exposure to oxygen in the air can cause acrylic to oxidize, resulting in changes in surface color. Especially when acrylic bathtubs are exposed to outdoor environments, contaminants such as humidity and dust can accelerate the oxidation process, affecting color stability.

3. Chemical Exposure

During use, the bathtub surface may come into contact with chemicals such as detergents, bleach, and chlorinated water. These substances can react with acrylic, potentially causing fading or discoloration. While most high-quality acrylic materials are treated with protective coatings, prolonged exposure to chemicals can still affect their appearance and lifespan.

4. Temperature Fluctuations

Severe temperature fluctuations can also adversely affect acrylic. The fluctuating water temperature in an outdoor whirlpool hot tub causes the acrylic surface to expand and contract. This long-term alternation between hot and cold can damage the surface, affecting its color uniformity. Although acrylic is inherently heat-resistant, fading can occur under extreme temperature fluctuations.

5. Improper Cleaning Methods

Using inappropriate cleaning tools and detergents is also a significant factor in acrylic fading. Using rough cloths, hard brushes, or abrasive cleaners can scratch and damage the acrylic surface. These scratches can make it more susceptible to dust and dirt, accelerating fading.

How to Prevent Fading in an Acrylic Outdoor Whirlpool Hot Tub?

1. Choose a Bathtub with a UV-Protective Coating

To reduce the effects of UV rays on acrylic, many high-quality acrylic outdoor whirlpool hot tubs feature a UV-Protective coating. This coating effectively blocks UV rays, minimizing their damage to the acrylic material and reducing the risk of fading. Therefore, when choosing a bathtub, consumers should choose one that offers a UV-protective coating to ensure it resists fading over time.

2. Regular Cleaning and Maintenance

Regular cleaning and maintenance are crucial for maintaining the vibrant color of your acrylic outdoor whirlpool hot tub. Using a mild detergent and a soft cloth to clean the bathtub's surface effectively removes dirt and scale, preventing accumulation and damage to the acrylic. Avoid using abrasives or harsh cleaning tools, as these can scratch the surface and accelerate fading.

Also, use cleaning and maintenance products specifically designed for acrylic, which often contain ingredients that protect the surface's gloss and color. Regular use of these products can help maintain the bathtub's appearance and extend its lifespan.

3. Use a Bathtub Cover and Protector

To reduce direct sunlight exposure to the bathtub, it's recommended to use a bathtub cover or protector. Especially when the bathtub is not in use, using a cover not only protects the bathtub from direct UV rays but also reduces the impact of environmental factors on the bathtub's surface. This method is very effective in delaying fading, especially when the bathtub is not in use for extended periods.

4. Install the Bathtub in an Appropriate Location

Choosing a suitable installation location can also effectively reduce the effects of UV radiation on the bathtub. For example, install the bathtub out of direct sunlight or plant some greenery near the bathtub to provide shade. This will reduce the direct sunlight exposure, thus reducing the effects of UV radiation and preventing prolonged exposure to strong sunlight.

5. Regular Inspection and Maintenance

Regularly inspect the exterior of the acrylic bathtub, especially checking for cracks, scratches, and damage. These damages not only affect the bathtub's appearance but also accelerate moisture and air infiltration, leading to fading and aging. If any problems are found, repair and maintain them promptly to prevent further deterioration.
