PROMASPRAY®-F5

Advantages

Structures protected with PROMASPRAY®-F5 can provide fire resistance for up to 240 minutes.
Does not release toxic or hazardous fumes, and presents no known health hazards either before, during or after application
The surface may either be spray textured, roller or float finished

PROMASPRAY®-F5 is a spray applied, single package factory controlled premix, based on vermiculite and Portland cement. PROMASPRAY®-F5 produces a monolithic coating able to withstand the thermal shocks experienced in a high intensity hydrocarbon fire. Concrete structures in particular, will be protected from explosive spalling when coated with PROMASPRAY®-F5. Although low in density, thus significantly reducing dead load, PROMASPRAY®-F5 is highly durable and will not crack or spall under mechanical impact. PROMASPRAY®-F5 is used for application on construction elements such as concrete or individual steel sections. It is also used extensively for the refurbishment or upgrading of existing tunnel structures.

Applications

PROMASPRAY®-F5 is used for tunnel adn oil & gas applications on construction elements such as concrete or individual steel sections. It is also used extensively for the refurbishment or upgrading of existing structures.

Properties and Performance

< #Back#

Acoustic Insulation	Noise reduction coefficient (NRC) 0.35
Alkalinity	12pH - 12.5pH
Corrosion Resistance	Does not promote corrosion of steel. However, a primed substrate is recommended for long term corrosion resistance, particularly when the structure is to be fully exposed to the elements. See Preparation
Density	775kg/m³ ± 15% (when dry and in place)
Finishing	May be floated or roller finished.
Fire Protection Thickness	Fire protection thickness requirements are often specified in the owner operator’s engineering codes of practice. Alternatively, please consult Promat Technical Department.
Full Cure	By hydraulic set
Initial Set	2hourto 6hour at 20°C and 50% RH
Minimum Practical Thickness	8mm when unreinforced, 15mm when reinforced.
Theoretical Coverage	62m²/tonne at 25mm thickness
Thermal Conductivity @ 20 °C	0.19W/m°K
Top Coating	Under certain circumstances, decorative top coating systems maybe used as protection from frequent wash down, long term chemical spills, or for improved resistance to fungal, algae and bacterial growth. Please consult Promat for details.

Substrates Preparation	The substrate shall be clean, dry and free from visible moisture (including condensation), concrete laitance, formwork release oils, loose mill scale, loose rust and any other condition preventing good adhesion. Concrete curing agents should not be used.
Typical Substrates Preparation	Concrete and steel
Application Initial Steps	Application of PROMASPRAY®-F5 must be carried out by an applicator recognised by Promat and applied in accordance with the installation guide available from Promat.
Application Limitations	PROMASPRAY®-F5 may be applied when the substrate and air temperatures are at least 2°C and rising, but should not be applied if the substrate or air temperatures are less than 4°C and falling. Maximum substrate and air temperature is 50°C. Substrate temperature should be at least 2°C above dew point temperature.
Application Method	Mix PROMASPRAY®-F5 with potable water in a suitable mixer and apply by a spraying machine approved by Promat. PROMASPRAY®-F5 may also be float or roller finished or left with a spray texture. Hand applied patching mix, PROMASPRAY®-F5T is available for minor repairs. Please refer to product data sheet of PROMASPRAY®-F5T.
Preparation Mesh Reinforcement	Most fire tests conducted have been carried out without mesh reinforcement, to demonstrate the ability of PROMASPRAY®-F5 to stay in place under the most severe fire conditions. However, for maximum long term in-service durability, the use of lightweight mesh reinforcement is recommended for exterior work and for interior use where vibration or mechanical damage and the possibility of subsequent loss of adhesion exist.
