Stucco & Brick Siding

DOWNSTREAM METHOD EQUIPMENT:

ATTENTION: This surface requires a Sodium Hypochlorite dilution level of 3% or higher. Downstream injectors typically do not allow such a strong dilution level. It's recommended to use a proportioned system like a 12-Volt or Gas Powered Soft Wash System.

PROPORTIONED METHOD EQUIPMENT:

• Soft Wash System 5 GPM or Better, 60 PSI or Better
• Soft Wash Proportioner
• Soft Wash Wand and J-Rod Nozzle

AVERAGE CLEANING RATE:

1000-1500 sq ft per hour

IMPORTANT NOTES:

The mortar holding the stones in place can be brittle or even allow the stones to be loose. DO NOT USE HIGH PRESSURE as this can loosen stones even further or cause damage. Only use a low pressure system or applying chemical and rinsing.

SCOPE OF WORK:

Before beginning, ensure you have completed all the steps in the Worksite Preparation Guide.

1. PRE-RINSE

   Use a wide mouth, large orifice nozzle (like a black soap nozzle or M5 Twist) to rinse the entire surface. The goal is to clear any loose dirt or debris and to cool down the surface before pre-treating it with chemical.
   
   Also, rinse all the grass, shrubbery, flowers, plants, and vegetation that the soft wash treatment has the ability to be oversprayed on. This will create a water barrier to protect the plants and minimize risk of damage.

2. APPLY SOFT WASH SOLUTION

   Adjust your protportied settings to reach 3-4% sodium hypochlorite dilution levels with a medium amount of soap. (See: Soft Wash Mixing Ratios) Apply mixture will begin to break down organics and clean the concrete. Apply a even coating across the entire surface.

   Pro Tip: Always apply soft washing solution from the bottom to the top. This will cause the chemical not to run and create streaks. The goal is to coat the surface without much chemical moving. 
   

3. ALLOW TO DWELL

   While keeping the surface wet, allow up to 15 minutes of dwelling time for the soft wash solution to work.

4. RINSE & INSPECT

   Once the entire surface has been cleaned, it's time to rinse. Turn off the downstream injector or place the proportioner to only water. Use partially open ball valve or a M5 Nozzle to rinse the entire concrete clean. Inspect the surface for any missed spots. Repeat steps 2-4 as needed.
   
   Pro Tip: Make sure you thoroughly rinse the windows. Sodium Hypochlorite left unrinsed for long or hot periods can cause etching on certain glass.
   
   Pro Tip: Always rinse from the top down.
