To make interior structural steel, concrete substrates or any other elements more resistant to fire or heat are special designed fireproofing, refractory and high temperature insulation mortars available.
They have to be sprayed on to protect surfaces, or used for filling of fractures and openings.
Some of them can even be processed in mixing pumps with short mixing time only, some need to be mixed for minutes and require an open system with batch mixer and worm pump.
Scope of materials:
- gypsum based cementitious spray-applied fireproofing
- cementitious fireproofing plaster
- high temperature insulation mortar
- refractory mortar
