Antifire Spray for Reinforced Concrete Elements
TERFIX P
A. Properties
Antifire spray for thermal insulation - plaster based on water-diluted dispersions an on the mixture of silicate fillings, mineral fibres and other agents. Without any asbestos and heavy metals.
Exterior: It is delivered without any surface finish, the surface is rough, jagged, grainy with the structure of sprayed plaster, which is the typical property of this material. Terfix P may not be smoothened on the surface.
B. Designation
It is designed for protection of bearing reinforced concrete structures with the fire resistance for 15 to 180 minutes according to the dimensional tables for individual elements. (E - Technical Data).
C. Application
Application may only be executed on surface free of mechanical impurities and smear. The structures must be with temperature +5°C as the minimum, and this temperature must not drop below the freezing point for the whole period of the spray hardening, as well as the temperature of the surrounding environment.
Method of coating - spraying, or in case of emergency (in emergency and locally only) by throwing on the clean surface free from smear and from mechanical impurities, and with a sound mechanical base.
Thickness of the layer is between 3 and 21 mm and is given by the requirement of fire resistance of the structure, and by the method of application. With thickness given in tables, the surface of the structure must be covered with an insert from zinc-coated gauze with eyes of 20 - 30 mm in compliance with Article 9 d of the ČSN 73 0821. The method of the insert affixing must be estimated by the designer according to the stress application on the structure.
Additional surface finish finish as for interior shall not be obligatory, however, it must be executed in all cases, should not the permanent impact of water, increased moisture, or meteorological influences be excluded.
The method of spraying is to be considered separately, if the structure should be under permanent dynamic stress ( vibrations, etc.). The spray as for the day of processing of the Catalogue Sheet is without any valid certificate of the VZT protection.
D. Delivery Terms
Exclusively as delivery including execution, with the certificate of execution.

An interpolation based on principle that as for thermal insulation, TERFIX P spray of 6 mm shall correspond to 10 mm of concrete is possible between the standard and modified tables. The enlargement of minimal cross sections, minimal axial support distance, minimal spray thickness and lowering the corresponding loading than given in the tables shall indicate the conclusion that these procedures shall be possible to apply without any other evaluation
- Prestressed ceiling structuresí (with the SPIROLL, SPA,SPW,Partek panels, as well as those of ECHO from concrete B 55 and better with the minimal thickness of 150 mm, width of 1200 mm with a seal, bottom support of the min. rope cross section of 9.3, cohesive with concrete and the bottom support cover of min. 35 mm. The panels may be discharged by linear holes with circular cross sections. The maximum allowed spray thickness (under observance of the thickness sizes given in the following table, is of 12 mm, the spray must be anchored to the panels by means of the SOKRAT 2804 A penetrating spray, diluted with water according to the ratio of 1:4. WARNING - the adhesion shall always be dependent on the level of the panel surface being kept free from smear.

G. Life - Aging
Regarding to the structure and nature of the material, the guarantee of life for all used raw materials, and in particular the ten years' experience with the spray application, any renewal during the life of the structure shall not be predicted. However, as for the long-term point of view, the real life shall be assessed according to the corrosivity caused by the environment and the spray exposition concerning a concrete structure
Moisture resistance: As for outdoor application, the TERFIX P insulating plaster shall always be protected against atmospheric influences by means of hydrophobisation. The finish outline must always be solved together with the project - a certified plaster of degree I or Q shall be applied. The application outdoors without any gauze may not be recommended.
