What it is, what it does, and everything else you need to know about Spray Fireproofing.
No one wants to consider the devastation of a fire. Still, the threat of a fire is an ongoing concern for home and business owners alike. How can you prevent a fire from destroying your home or building? By fireproofing, of course!
Whether your space is in the stage of renovation or being built from the ground up, spray fireproofing increases the security of your structure, reduces liability, and provides air-tight thermal protection. Fireproofing products are used to delay the failure of steel and concrete structural elements that are exposed to high temperatures. This is done by thermally insulating the structural pieces to keep them below temperatures that cause failure.
Spray Fireproofing Uses
Spray fireproofing is used to protect the ridges of structural pieces from extreme heat during a fire. However, spray fireproofing is not suitable for surfaces exposed to moisture or levels of high humidity. If exposed, the products will deteriorate. Likewise, the moisture can cause mold to grow, which in turn can result in health issues in those exposed.
Spray Fireproofing Preparation
When preparing to use the spray fireproofing, the room temperature must sit at a minimum of 4ºc at least 25hrs prior to, during, and after, the application unless otherwise recommended by a manufacturer. Natural ventilation is appropriate, as are dedicated sources of water. Likewise, protection and covering of all the materials that are not receiving the application is also necessary.
A contractor should check the underlying layer prior to application, as well as ensure the following steps have been prepared:
- Surfaces cleaned of oil, grease and dirt.
- Steel decks cleared of any lubricants.
- Attachments required to distribute the fireproofing are in place.
- Adhesive or primers should be applied when recommended by the manufacturer.
Spray Fireproofing Application
Typically, spray fireproofing is sprayed on using two methods: a wet or dry spray. Note, proper lung and eye protection is absolutely required during mixing and application.
Wet Sprays are combined with water to form a substance that is dispersed via hose with air through a nozzle. This process aids in installation time by 10-15% per day.
Dry Sprays are conditioned through equipment and then passed through a hose to a nozzle where atomized water is introduced. The spray is then directed and applied in an even coat. This type of application is useful for harsh weather conditions.
