Protecting the steel structure in the event of a fire is a key consideration. The vermiculite spray is used as fireproofing for both internal and semi exposed elements mainly of steel structure, hollow core slabs and concrete slabs.
What is vermiculite?
This hydrous phyllosilicate mineral undergoes significant expansion when heated. A monolithic coating is adopted with a mixture of vermiculite as well as Portland cement to withstand the fire. Vermiculite is more preferred because of low density which will not add extra deaf load to the building and high durability. The damage or crack to the layer is minimal during any mechanical impact.

The needed thickness for the vermiculite Application spray can be calculated at the site according to the structural member sizes and the fire rating needed based on manufacturer guidelines.
Vermiculite plaster has evolved from across the world research and many years of experience in the field of passive fire protection systems. This plaster is a special dry powder coating that is developed to protect any form of structural steel such as beams, columns, tanks and so on. Vermiculite is mixed with water and its entraining agent at site and can be applied by hand traveling at ease.
Vermiculite plaster consists of inorganic mineral compounds with a vermiculite base. It is non combustible, lightweight, smooth and environmentally friendly as well as very easy to handle, making it suitable for a wide range of applications. It is completely asbestos free, non hazardous and safe during and after application.
Vermiculite plaster is tested for its fire resistance as per international practical. Vermiculite fire spray is effective at retaining moisture, thus in the event of a fire, this moisture turns into steam, substantially delaying an increase in temperature and providing fire resistance for up to 240 minutes.
Effective yet inexpensive
Vermiculite coating steel structure is used to protect internal steel, ducts and ceilings and is fabricated from cement fibers. Vermiculite and plaster has a low production cost and let's fast application. It is applied on site and the final finish of vermiculite is bold and textured such as rough concrete and often sets between 10-12mm in thickness.
You can vermiculite spray online at very affordable prices. Buying online saves your valuable time and money.
