How to Remediate Heavy Surface Mold -- MSI-4 Zones

Heavy surface mold can be pesky to remediate. The past few weeks we have been reviewing the best ways to remediate mold based on it's severity. In this post, we will be covering how to remediate a MSI-4 zone which is characterized by heavy and consistent mold with sporafic pigmentation staining.


Mold Severity Indexing is a tool that helps contractors define the mold levels of a zone within a property properly and efficiently. It is based off of the conditions defined by the IICRC but goes more in depth so the best application can be practiced to treat the zone and yield the best results!


Spectrum of MSIs:




MSI-4 Remediation

When covering MSI-3 we introduced our recommended REACT | EXTRACT method. We recommended this for MSI-4 zones as well with a re-reaction and re-extraction.


REACT | EXTRACT is a system of remediation where the neutralization between two proprietary products, OxyPrep and OxyPar LR, followed by vacuum extraction, result in superior remediation. Depending on the severity of the situation, REACT | EXTRACT methods may be repeated; for MSI 4, they are just implemented twice. It is a superior method to remove deep soil loads and disinfect the area. This process is based on information and recommendations from the industry standard, IICRC S-520.


Also, we have created materials to help you walk through these steps. These resources can be found under the Learn tab, on the Procedures page.


The first tool is an in-depth Step-by-Step guide. It will take you through what materials are needed to complete the job, how you should prepare, how to scale what product you will need, and use instructions. This guide helps you think through how much product you may need to order and what small things will leave your customer most satisfied with their results.


The second tool we have created is a Cocktail Card. This is a resource that you can quickly pull up on the job and remind yourself of some steps that need to take place or materials that will be needed. It also offers some helpful tips so you can ensure you preforming the best practices.
