How does Actiwash work?
Actiwash affects the proteins and cell membrane of microorganisms, consequently causing the release of nitrogen and phosphorus from cells. Where an apply and leave application is used, the processes of natural weathering work to eliminate the dead biofilm staining. 

How long does the self-cleansing process (spray/brush & leave) take?
(1) Green algae stains should disappear within a week. (2) Red algae stains should disappear within 2-3 weeks. (3) well established dark staining can take several months to disappear. Gradual lightening of the surface contamination should be noticeable within the first few weeks and months following treatment. Note: Severe biofilms may require an additional application. However, this is not typically necessary. A brush agitation of the Actiwash solution is advisable on heavily contaminated areas.

Render treatment

Equipment

1. Chemical applicator (sprayer, knapsack sprayer etc.)
2. Brush
3. High Reach Equipment

Preparation

Examine the render being treated and take note of the type(s) of staining present. Red, green and dark discolouration is treatable with an application of Actiwash Softwash. Orange iron staining will require attention with a separate rust removal product. These stains are typically caused by flue pipes and ferrous metal fixtures. Ensure the render if free from loose dirt. Be mindful that areas close to the ground may be affected by mud splashes. If so, rinse these away with water and a suitable detergent.

Dilution

Mild Treatment: 40:1

Heavy Treatment: 25:1

Application

1. Prepare a diluted solution of Actiwash Softwash in the tank of the chemical application equipment.
2. Saturate the (dry) render with the prepared solution by either spray or brush, then leave

Post Application

• The biofilm dies shortly after saturation with Actiwash Softwash while the render is drying.
• Afterwards, the processes of natural weathering take control to clean away the staining.
• Each organic stain will eventually disappear, with some diminishing quickly and others taking more time. For example, green
  staining will disappear within a week. Red staining will take 1-2 weeks. Black/dark staining can take several months to disappear; however, gradual lightening of the contamination should be noticeable within the first few weeks and months following treatment. Yellow and white spots (lichens) can often be the final contaminant remaining to be weathered away. The crust will dry out and recede.
• Rain and freeze-thaw weather cycles are beneficial.

Roof Treatment Guide

Equipment

1. Chemical applicator (sprayer, knapsack sprayer etc.)
2. Brush
3. High Reach Equipment
4. Scooping or suction equipment for removing waste from the gutter.
5. Scraper for removing heavy moss deposits

Preparation

The preparation stage involves the removal of moss from the surface of the roof. Typically, this is the most demanding aspect of treating a roof with Actiwash, and necessitates safeguarding the gutter while collecting the falling moss.

Dilution

Mild Treatment: 35:1

Heavy Treatment: 25:1

Application

1. Prepare a diluted solution of Actiwash Softwash in the tank of the chemical application equipment.
2. Saturate the (dry) roof with the prepared solution by either spray or brush, then leave.

Post Treatment

• The biofilm dies shortly after saturation with Actiwash Softwash while the roof is drying. Afterwards, the processes of natural weathering take control to clean away the staining.
• Each organic stain will eventually disappear, with some diminishing quickly and others taking more time. For example, green staining will disappear within a week. Red staining will take 1-2 weeks.
