Why use Dry Ice Blasting?

Dry Ice Blast Cleaning has been proved highly successful with mold removal because the force of the spray of pellets can quickly wipe a surface clean. Many hours of time are saved. Not only is the mold removed but the top layer of wood that has the roots of the mold can be removed too. This leaves the wood clean and mold free.

Since sanding, grinding and scraping are physically intensive processes and require that the tooling be forcefully applied to the surface to be cleaned, the position of the Mold Remediation Technicians doing the work must be very stable. Working on attic trusses, for example, carries an increased risk of falling due to the force that needs to be exerted for the work to be done properly. When using Dry Ice Blasting, the dry ice blaster can clean many angles and surfaces in just the time it would take to prepare for grinding the same area. In a typical home attic remediation project the actual removal work using traditional cleaning methods may take up to 5 working days. By using Dry Ice Blasting, that process may reduced to 3 days. In addition, the Dry Ice Blasting allows effective cleaning in tight areas such as the area where a floor joist meets the floor sheathing where hand cleaning methods are difficult to use.

1. Construction of Critical Containment Barriers
A containment barrier is plastic sheeting that is installed to close off a contaminated area from a clean area. Multiple barriers may be installed, depending on the degree of mold infestation.

2. Discarding of Contaminated Building Materials
The decision to remove and replace mold contaminated building materials is dependent on the composition of the infested material. Porous materials like drywall or particleboard are generally discarded, since mold contamination runs marbled throughout the compound. Semi-porous materials like wood framing made of plywood and 2 x 4 studs can generally be remediated. These materials are dry ice blasted to remove imbedded mold spores. Nonporous materials like granite and semi- or high-gloss painted trim can simply be decontaminated
 

 3. Dry Ice Blasting Contaminated Surfaces
CO2 (dry ice) pellets are shot at high velocity onto the infested surface to blast the mold from the surface. An advantage of this method is its ability to clean surfaces regardless of the surface shape. The pellet form of dry ice is used to etch the first and second layer of wood from the framing where mold spores and hyphae can hide. The ice pellets freeze the mold and the moisture in the surface wood. This makes the surface layer brittle and easier to break away from the surface being cleaned. Upon contact, the dry ice converts from solid form to a harmless gas, leaving no messy residue to clean up. The freezing process creates no airborne blasting powder that can carry mold spores to uncontaminated areas. After ice blasting, the surface is HEPA vacuumed to remove any contamination missed by the blasting procedure. As a third precaution, the HEPA-cleaned surface is then wiped down with detergent and anti-microbial solution.

4. Application of Clear Anti-microbial Sealant to Remediated Framing
All clean wood surfaces are sealed with a clear anti-microbial sealant to protect the wood from future mold infestation. All surfaces treated by Residential Remodelers. LLC. carry a 3-year manufacturer's warranty that guarantees mold will not grow back or attach itself to the treated surface.
