For portable buildings, different sidings require specific types of paint to ensure optimal protection against the elements and maintain vibrant colors. In this article, we will explore various paint options for LP SmartSide, Hardie Siding, and Metal Siding—choices made available by Blacks Buildings—along with their pros and cons. Additionally, we’ll provide seven tips on maintaining color vibrancy and five indicators for when it’s time to repaint.

LP SmartSide Paint Options

1. Acrylic Paint

Description: Water-based acrylic paint has good adhesion to LP SmartSide.


  • Quick Drying Time: Acrylic paint dries rapidly which translates to faster project completion.
  • Easy to Clean: Water-based acrylic paint is easily cleaned with water.
  • Resistant to Fading: Acrylic paint has good resistance to fading so it’s easy to maintain vibrant colors over an extended period.


  • Durability: While acrylic paint has decent durability, it may not match the performance of oil-based alternatives in challenging weather conditions.

Best Use:

  • Ideal for budget-conscious projects where quick application and ease of use are priorities.
  • Suitable for areas with moderate weather conditions and limited exposure to harsh environmental conditions.

When the More Expensive Option is Unnecessary: Acrylic paint is sufficient for projects with less demanding weather conditions, so it’s unnecessary to choose a more expensive paint type.

2. Oil-Based Paint

Description: Solvent-based oil paint delivers superior durability for LP SmartSide.


  • Exceptional Weather Resistance: Oil-based paint provides superior resistance to rain, snow, and UV rays.
  • Durability: This type of paint forms a sturdy barrier that withstands the test of time.
  • Glossy Finish: Oil-based paints enhance the LP Smartside visually due to its glossy finish.


  • Longer Drying Time: This paint typically needs more drying time.
  • Strong Odor: The application of oil-based paints can produce a strong odor and requires proper ventilation.

Best Use:

  • Recommended for LP SmartSide installations in areas with extreme weather conditions such as high humidity, intense sunlight, and temperature fluctuations.
  • Suitable for long-term projects where durability and a glossy finish are desired.

When the More Expensive Option is Unnecessary: In regions with mild weather patterns and limited temperature variations, the enhanced durability of oil-based paint may be unnecessary.


Hardie Siding Paint Options

1. Fiber Cement Paint

Description: Specifically formulated for fiber cement due to its outstanding adhesion and flexibility.


  • Crack and Peel Resistance: Because it is formulated for fiber cement, this paint resists cracking and peeling and keeps the surface intact.
  • Long-Lasting: Fiber cement paint has superior longevity and a durable coating that requires less frequent repainting.
  • Excellent Color Retention: The paint maintains its color vibrancy over time.


  • Cost: Fiber cement paint may be relatively more expensive compared to other options.

Best Use:

  • Ideal for high-traffic areas or regions prone to heavy rainfall.
  • Recommended for projects where long-lasting color retention is needed.

When the More Expensive Option is Unnecessary: In areas with minimal temperature fluctuations and milder weather conditions, the features of fiber cement paint may not be value for money.


2. Latex Paint

Description: Water-based latex paint is suitable for Hardie Siding.


  • Quick Drying: Latex paint dries quickly.
  •  Low Odor: Water-based latex paint produces minimal odor and using it creates a more comfortable painting environment.
  •  Ease of Cleaning: Easy cleanup with water simplifies the maintenance process.


  • Durability: Latex paint may not be as durable as oil-based alternatives and may require more frequent repainting.

Best Use:

  • Suitable for Hardie Siding installations in regions with moderate climates and lower exposure to extreme weather conditions.
  • Recommended for projects with budget constraints and where a quick-drying, low-odor option is ideal.

When the More Expensive Option is Unnecessary: In areas with mild weather conditions and when a shorter lifespan is acceptable, the low-cost latex paint will be a better option over the more expensive alternative.


Metal Siding Paint Options

1. Direct-to-Metal (DTM) Paint

Description: Formulated specifically for metal surfaces and has great corrosion resistance.


  • Excellent Adhesion: DTM paint has reliable adhesion resulting from the strong bond it forms with metal surfaces.
  • Corrosion Resistance: Specifically designed for metal, DTM paint helps prevent corrosion and rust.
  • Limited Color Options: The color choices are fewer compared to other paint types.


  • Potential for Multiple Coats: In order to achieve optimal protection, you may need to apply multiple coats of DTM paint.

Best Use:

  • Recommended for metal siding in coastal areas or locations prone to high humidity.
  • Suitable for projects where color options are limited but corrosion prevention is a priority.

When the More Expensive Option is Unnecessary: Inland projects with milder climates where the additional corrosion resistance of DTM paint may not be essential.


2. Rust-Oleum Paint

Description: Rust-Oleum produces paints designed to inhibit rust on metal surfaces.


  • Rust Prevention: Rust-Oleum paints are formulated to effectively inhibit rust on metal surfaces.
  • Easy Application: The application process is user-friendly and easy to use for DIY projects.
  • Various Finishes: Rust-Oleum is available in different finishes and shades.


  • Multiple Coats May Be Necessary: Depending on the condition of the metal, several coats might be required for optimal protection.

Best Use

  • Ideal for DIY projects and smaller budgets because it doesn’t need professional application.
  • Recommended for projects with minimal exposure to harsh weather conditions.

When the More Expensive Option is Unnecessary: In projects where the primary concern is rust prevention, and a more budget-friendly option is sufficient, rust-oleum is cost-effective.


Paint Options and Tennessee Weather

Tennessee experiences different climates throughout the year, characterized by hot summers, mild winters, and occasional temperature fluctuations. The state is prone to thunderstorms, and certain regions may have high humidity levels. With these weather patterns, the range of options apply for different weather situations.

1. LP SmartSide

  • Acrylic Paint: Ideal for most areas in Tennessee due to its quick drying time and resistance to fading; suitable for regions with moderate humidity and temperature fluctuations.
  • Oil-Based Paint: Recommended for regions in Tennessee with higher humidity and more extreme weather conditions; able to withstand the occasional intense heat and storms.

Tennessee-Specific Advice: For LP SmartSide in Tennessee, acrylic paint is good for general use. Reserve oil-based paint for locations prone to more severe weather conditions or higher humidity levels.

2. Hardie Siding

  • Fiber Cement Paint: Well-suited for rain-battered regions of Tennessee because it’s resistant to cracking and peeling. It is recommended for portable building projects where long-lasting color retention is necessary.
  • Latex Paint: Suitable for areas with milder weather conditions and lower exposure to extreme elements. It’s also ideal for budget-conscious projects.

Tennessee-Specific Advice: In Tennessee, especially in areas prone to heavy rainfall, use fiber cement paint for its crack and peel resistance.

3. Metal Siding

  • Direct-to-Metal (DTM) Paint: Ideal for areas beside the lakes and rivers of Tennessee as a result of excellent adhesion and corrosion resistance. Also suitable for portable buildings facing occasional intense storms.
  • Rust-Oleum Paint: Great for more moderate climates within Tennessee, without any severe weather fluctuations that could corrode metal. 

Tennessee-Specific Advice: In Tennessee, particularly in areas with higher humidity and occasional storms, opt for DTM paint for metal siding for added protection against corrosion and ensures longevity.


Overall Tips for Maintaining Color Vibrancy

Preserving the vibrant color of your portable building’s exterior is dependent on maintenance. Here are practical tips to maintain color vibrancy to make sure that your portable building meets the high standards for design and durability. 

1. Regularly Clean and Avoid Harsh Cleaners: Regularly clean the surface to remove dirt and pollutants to preserve the vibrancy of the paint. Gentle cleaning products prevent damage to the paint to ensure a longer-lasting finish.

2. Trim Overhanging Trees: Trim trees to prevent shade and reduce the risk of moss growth that will result in maintaining a clean appearance.

3. Apply UV Protectant: UV protectants shield the paint from sun damage and help prevent fading and discoloration.

4. Regular Inspections: Periodic inspections can help identify and address issues like chipping or peeling paint early on.

5. Protecting Against Harsh Weather: Apply a weather-resistant sealant to improve protection against rain and extreme weather conditions.

6. Using High-Quality Paint: Invest in high-quality, weather-resistant paint to ensure long-term durability and color retention.

7. Proper Surface Preparation: Adequately clean and prime materials before painting, it will contribute to the longevity of the paint job.


Know When to Repaint

The wear and tear on the exterior surfaces can be subtle but may affect both the structure’s appearance and longevity. Knowing when it’s time to repaint is important to maintain the durability and beauty of the shed. Here are some ways to know when a repaint is needed:

1. Fading Colors: Dull or faded colors indicate a loss of vibrancy and signal the need for a fresh coat of paint.

2. Chipping and Peeling: Addressing chipped or peeling paint promptly prevents further deterioration of the surface.

3. Visible Stains: Stubborn stains that resist cleaning need repainting to restore the appearance.

4. Cracks and Blisters: Cracks and blisters is an indication of breakdown of the paint film, and requires repainting for protection.

5. Signs of Rust on Metal Siding: Any visible signs of rust on metal siding should be treated immediately with a new coat of paint to prevent further corrosion.
