Firespray ^® implementation techniques

Firespray ^® coating is sprayed on. The spraying technique, also known as flocking, consists in applying Firespray^® fibres under pressure, using a special machine.
The expected thickness will be defined according to the required fire resistance rating.

Spraying is carried out using a hydro-pneumatic spraying machine.
This comprises a feed hopper, a carding device, a blowing device (fan, turbine or blower), a hose for conveying the mixture to be sprayed.
A spray gun and water.

The product is carded in the machine and then conveyed through a hose to a spray gun using compressed air. Water-fed nozzles are placed around the hose outlet to wet the product before it is sprayed onto the substrate.

Firespray^® does not require a bonding agent to be applied beforehand.

The applied coating will be finished with Projiso Fixo Dur^® ou le Sidairless^®
