Cretex HT is a specialised high-temperature formulation of refractory cements and blended aggregate which, when mixed with water, forms a cement-like material capable of withstanding temperatures of up to 1400°C when fully cured.
Cretex HT is a specialised high-temperature formulation of refractory cements and blended aggregate which, when mixed with water, forms a cement-like material capable of withstanding temperatures of up to 1400°C when fully cured.
Use on: most common building materials including concrete, breeze block, brick and stone.
Use where: Internal and external
Typical industries: Suitable for use in incinerators, kilns and commercial oven installations.
Application thickness: The recommended range of application thickness is from 6mm (general repairs) or 13mm (screeds) minimum to 50mm maximum in one layer.
Approximate coverage: 20 kg unit – 0.35m2 nominal thickness
Special features: Capable of withstanding temperatures of up to 1400°C when fully cured.
Pot life: The material should initially be kept cool and wet. Cover with polythene sheeting or wet cloth after 6 hours, and keep covered until 24 hours after application. A further 24 hours of natural drying should be allowed before any heat is applied. Initial heating should be as gentle as possible to allow the remaining moisture to escape without damage.
Application temperature: +10°C – +25°C. Not below +10°C.
Number of parts supplied: 1
Please consult the technical data sheet for full technical product data.
Preparation:
THOROUGH SUBSTRATE PREPARATION IS ESSENTIAL.
Concrete repairs should be prepared with squared off edges having a 6mm minimum vertical lip. Remove all loose material – wire brushing is advisable.
Sweep clean or vacuum. The surface must be free from grease, oil or contamination. A gas torch will help to remove oil from the surface.
Mixing:
Having prepared the surface, add an accurately measured quantity of clean water to the powder at a rate of 4.25- 4.75 litres per 25kg unit of Cretex HT
powder. Mix thoroughly for 1-2 minutes until a homogenous mix is achieved. Inadequate or excessive mixing can adversely affect the strength of the
material. For best results use a heavy duty slow speed drill and mixing paddle.
DO NOT MIX MORE THAN CAN BE APPLIED IN 15 MINUTES.
For screed and thin layers – provided the service temperature will not exceed 500˚C, the strength and adhesion of the mix may be enhanced by adding
Polycote Bondex mixed 1:1 with the mixing water, or using Bondex undiluted in place of the mixing water when minimum section thickness is required.
Please refer to Polycote Bondex Data Sheet.
Application:
Dampen the prepared surface with water to reduce suction. Place the material immediately after mixing, using a trowel or float. Avoid excessive trowelling of the applied material as this may weaken the resultant surface.
