Limewashing Brick vs. Rhino Shielding Brick: Choosing Between Tradition and Technology for Pittsburgh Homes

When it comes to enhancing the appearance and durability of brick surfaces, Pittsburgh homeowners face a choice between traditional methods and modern technologies. Limewashing, an ancient practice dating back to Roman times, offers historical charm, while modern options like Rhino Shield provide advanced protection and longevity.

Rhino Shield in Pittsburgh

For over 20 years, Rhino Shield exterior coating has been used on brick surfaces across the nation. Our product was even featured on HGTV’s Curb Appeal the Block, where it was applied over brick. We frequently repair and paint the exteriors of thousands of brick homes each year, and we often get asked, “How does limewashing compare to Rhino Shield in aesthetics?” and “Does limewashing offer protection similar to Rhino Shield?”

Let's explore both options to help you decide which is best for your Pittsburgh home based on your preferences and budget.

Limewashing

Ancient Origins and Composition Limewashing has a rich history, dating back to Roman times. This technique involves creating a lime putty from crushed and burned limestone, which is then aged, thinned with water, and colored with natural pigments. The result is a mottled and matte surface with a chalky texture, reminiscent of suede.

Limewash is a popular choice for exterior surfaces, especially on buildings with historical or traditional architectural styles. It can also enhance indoor walls and ceilings with its unique aesthetic.

Color Variability and Opacity Limewash is naturally off-white, and while pigments can be added, the color options are limited compared to modern paints. Limewash tends to produce softer, muted tones due to the use of natural, alkali-resistant pigments.

Achieving your desired color can be challenging, as limewash becomes significantly lighter as it dries. Typically, limewash is applied in up to three coats to achieve the desired opacity. The final color can vary based on:

• Pigments
• Surface composition
• Porosity
• Application techniques

Environmental Friendliness One of limewash's notable attributes is its breathability, allowing the underlying surface to facilitate moisture passage. This makes it suitable for historic buildings and structures with traditional construction methods. Limewash is also environmentally friendly due to its natural composition and low volatile organic compound (VOC) content.

Cost of Limewashing Limewashing is less expensive than a typical paint application, costing between $3,000 and $6,700 depending on the number of layers and square footage. However, limewash's durability is compromised over time, requiring reapplication every 5 to 7 years.

DIY or Professional Application? Limewash is available in cans at most home improvement stores, making it a convenient option for DIY enthusiasts. However, for optimal results, especially on exterior surfaces, professional application is recommended.

Rhino Shield

Increasing Popularity of Painted Brick The look of painted brick has become increasingly popular in recent years. People are looking to restore their brick homes and businesses with a nice color and sheen.

Thick Coating for Protection Brick requires a thick coating for two reasons:

1. Standard paint is thin and often gets absorbed into the brick, causing an uneven look. Thick coats provide a uniform finish.
2. Brick is porous and needs a coating thick enough to prevent water penetration, which accelerates mortar deterioration.

Benefits of Rhino Shield Rhino Shield has been a popular option for over 20 years. Here’s why:

Consistent Color and Aesthetic Preservation Rhino Shield offers consistent color options and can match virtually any color. We also offer sheen options for those who prefer a little gloss. For those who want to retain the natural brick look, we offer a clear coat for protection.

Breathability and Low VOCs Like limewash, Rhino Shield is breathable, preventing moisture from getting trapped beneath the surface. It also maintains low VOC levels, aligning with environmentally friendly standards.

Efficiency and Protective Advantages Rhino Shield requires only two coats—the primer and topcoat—for full protection. Our brick primer seeps into the brick pores, sealing them and bonding with the substrate. The topcoat is eight to ten times thicker than traditional paints, contributing to its durability against the elements.

Additional Benefits and Longevity

• Lasts at least 25 years with a warranty.
• Reflects UV rays, reducing A/C energy costs.
• Water repellence prevents mold, fungi, and algae growth.
• Provides insulation benefits.
• Acts as a fire retardant and is abrasion-resistant.
• Protects mortar and delays the need for expensive tuckpointing.

Long-Term Investment and Warranty While Rhino Shield has a higher initial cost—between $13,000 and $18,000—it pays off over time. Built to last at least 25 years, it is resistant to cracking and chipping due to its elastomeric flexibility. Our 25-year warranty ensures it’s a reliable, long-term solution.

Professional Application and Assurance Rhino Shield is only available through our professional installers, ensuring the job is done right. We back our product with a 25-year, transferable, and non-prorated warranty.
