How to Professionally Soft Wash a Facade: A Step-by-Step Guide to Restoring Your Property’s Exterior

Table of Contents

The facade of your home or business is the first impression people get of your property, and like any other part of your home, it needs regular care and maintenance to keep it looking its best. Over time, the exterior of your building can accumulate dirt, grime, mold, mildew, and other contaminants that not only affect the appearance but also the structural integrity of your property. While pressure washing is often a go-to cleaning method, it can be too harsh for delicate surfaces. That’s where soft washing comes in.

Soft washing is a safer, more effective way to clean exterior surfaces without the risk of damage caused by high-pressure water. It’s ideal for materials like render, wood, and painted surfaces, which can be easily damaged by traditional pressure washing methods. In this article, we’ll walk you through how to professionally soft wash a facade, ensuring you get a clean, safe, and long-lasting result.

What Is Soft Washing?

Soft washing is a low-pressure cleaning technique that uses a combination of water, specialized cleaning solutions, and a soft stream of water to gently remove dirt, algae, moss, and other debris from building exteriors. The solution used typically includes a mixture of water, detergents, and bleach to break down contaminants.

The key difference between soft washing and traditional pressure washing is the amount of pressure used. Soft washing utilizes a much lower PSI compared to pressure washing, typically around 500 PSI or lower, which is more than enough to clean the surface without causing damage.

Why Soft Washing Is the Best Option for Your Facade

  1. Prevents Damage to Delicate Surfaces
    High-pressure water can chip, crack, or even strip paint off soft or porous surfaces. Soft washing, on the other hand, gently cleans these surfaces without the risk of damage, making it perfect for facades.
  2. Eco-Friendly
    Soft washing uses biodegradable cleaning solutions, making it an eco-friendly option for maintaining the exterior of your property. The low-pressure method also reduces water waste, making it a sustainable choice for property maintenance.

How to Professionally Soft Wash a Facade

If you’re ready to restore the beauty of your building’s facade with a professional-grade soft wash, here’s a step-by-step guide to getting the job done:

Step 1: Gather the Right Tools and Equipment

To achieve professional results, you’ll need the right equipment. Here’s a list of the essential tools for soft washing a facade:

  • Soft Wash System: A pump and hose system that applies cleaning solutions at low pressure.
  • Cleaning Solution: A specially formulated solution for removing algae, mold, mildew, dirt, and stains. These solutions often contain bleach, surfactants, and other agents designed to clean and disinfect.
  • Low-Pressure Nozzle or Wand: A nozzle that provides low, steady pressure, ideal for washing delicate surfaces.
  • Ladders or Extension Poles: To reach high areas safely.
  • Protective Gear: Gloves, goggles, and a face mask to protect yourself from chemicals.
  • Bucket or Tank for Solution: A large container to mix and hold the cleaning solution.

Step 2: Apply the Cleaning Solution

It’s time to apply the cleaning solution. Here’s how to do it:

  • Mix the Cleaning Solution: Follow the manufacturer’s instructions for mixing the soft wash solution. Typically, this involves diluting a concentrated product with water. For tough mold or algae, you may need a stronger mixture of water and bleach.
  • Apply the Solution to the Facade: Using your soft wash system or a low-pressure nozzle, apply the cleaning solution evenly to the facade. Start at the bottom and work your way up to ensure that the solution doesn’t drip down on already cleaned areas.

The solution should cover the entire surface, including any spots where mold, mildew, or algae are present. Let it sit for 10–15 minutes to allow the cleaning solution to break down and loosen contaminants.

Step 3: Soft Wash the Facade

After letting the cleaning solution sit, it’s time to wash the facade. Using your soft wash system or low-pressure wand, gently rinse the solution from the surface. Start from the top and work your way down, allowing the water to flow downward and wash away dirt and grime.

Be sure to rinse thoroughly to ensure that no cleaning solution is left on the surface, as it can leave streaks or residue. The low pressure will prevent any damage to the surface while still effectively removing contaminants.

When to Call in the Professionals

While soft washing is a safe and effective method, it’s not always a DIY job. If the facade is particularly large, the building is several stories tall, or you have delicate or hard-to-reach surfaces, it’s best to call in professional soft washing services. Professionals have the equipment and expertise to handle large-scale projects safely and efficiently.
