Frequently Asked Questions

Why is a mineral base fireproof coating used?

Cement mineral base fireproof coating (code HDFC ™ 110) is suitable for protection of various materials including steel and concrete against fire and flames.

What are the main ingredients of HD mineral base fireproof coating?

The main materials of fire retardant coating are light expandable sand, perlite and vermiculite, mica and hydraulic mortar (cement).

Why is the fire-retardant HD mineral base fireproofing of the company used for environments with special restrictions?

This type of mortar can be used for indoor and outdoor environments of steel and concrete surfaces and prevents the heat caused by fire to reach the surface of the main material. The water-based nature of this type of fire-retardant mortar can be very helpful in environments with certain limitations (such as hospitals).

How does HD Mineral Base Fire Cover work?

After applying the fireproof coating, the thickness of the coating increases to such an extent that fire and fire have the least effect on the surface under the work.

Is it possible to use HD mine base fireproof coating on wood surface?

Due to the blue base of the high-density fire-retardant coating, Afzir Company does not emit dangerous gases during fire, and this type of insulation can be used in addition to concrete and steel on the surface of wood.

What colors are mineral base fireproof coatings available in?

HD mineral base fireproof coating is available in gray.
