A cementitious coating is a cement-based protective coating applied to steel surfaces. This guide explains its benefits and what to consider. See our cementitious coating page for more.
What is a cementitious coating?
Cementitious coatings consist of cement-based materials and additives designed to adhere to steel surfaces. They are used for corrosion protection, fire resistance and improved durability of steel structures in construction, infrastructure and marine applications.
Benefits
- Corrosion protection: a barrier against moisture, oxygen and other corrosive agents.
- Fire resistance: an insulating layer that delays the temperature rise of the steel.
- Durability: a protective layer that resists degradation from environmental factors.
- Adhesion and application: bonds well to steel and can be applied by spray, brush or trowel.
What to consider
Think about the intended application, environmental conditions, required thickness and compatibility with existing coatings or substrates. Proper surface preparation is essential for good adhesion and performance. Common types include Portland cement-based, magnesium phosphate cement-based and calcium aluminate cement-based coatings.

FAQ
Is a cementitious coating the same as cementitious fire proofing?
They are related. Cementitious fire proofing is the spray-applied fire resistive version used on structural steel. See our cementitious fire proofing page.
How is a cementitious coating applied?
It can be applied by spray, brush or trowel, depending on the product.
Where cementitious coating is used
Cementitious coating, also called cementitious fire proofing, is a cement-based layer sprayed onto structural steel, decks and concrete. It is a thicker, rougher layer than intumescent paint, so it is usually chosen where appearance is not the priority. It is a fire proofing coating, not a paint.
- Structural steel beams, columns and decks that will be hidden or finished later
- Plant rooms, car parks, warehouses and industrial buildings
More questions
How is it applied?
We review the steel and fire rating, prepare the surface, spray to the required thickness and inspect before handover.
