Pure Guard PROTECTS AN EXTERIOR STUCCO WALL NEAR A WATERFALL, REDUCING CLEANING COSTS

THE CHALLENGE

A luxury condo-hotel faced a persistent challenge of organic growth (algae, mold, lichen) on an exterior stucco wall adjacent to a decorative waterfall in the common area. The constant moisture and sunlight exposure created a conducive environment for organic proliferation, leading to unsightly blemishes and potential structural damage. Frequent manual scrubbing and power washing every 3 weeks proved ineffective and unsustainable, incurring high labor and water costs.

THE SOLUTION

Armus Pure Guard, a water-based, transparent surface protection with photocatalytic properties, was chosen as a long-term solution. Its unique formulation penetrates the stucco substrate, creating a chemically and physically robust barrier against organic growth. Pure Guard's photocatalytic properties continuously break down organic matter at the molecular level, preventing adhesion and promoting a self-cleaning effect.

IMPLEMENTATION

1. Surface Preparation: The exterior stucco wall was power washed and allowed to dry. 

2. Application: Pure Guard was applied directly to the dry surface using an HVLP sprayer to the point of rejection and allowed to dry.

20 months POST-APPLICATION RESULTS & evaluation

Twenty months after the Pure Guard application, the stucco wall adjacent to the waterfall remains free of any visible organic growth. No algae, mold, or lichen have reappeared, demonstrating the long-term efficacy of Pure Guard's photocatalytic protection. 



The elimination of manual scrubbing and power washing every 3 weeks has significantly reduced labor costs and operational disruption for the condo-hotel. Pure Guard's long-term effectiveness minimizes ongoing maintenance expenses compared to frequent cleaning, providing a cost-effective solution.
