Prepare your mixing container

Instructions for Casting a Slab with FYRECAST 1400
When casting on top of a solid base such as concrete or brickwork, the minimum thickness should be 25 mm, although 50 mm is recommended for added strength and thermal mass.
If the slab will be unsupported (i.e. spanning a gap or forming a suspended section), it must be at least 50 mm thick, and stainless steel fibres must be added to the mix to improve structural integrity.
Safety Guidelines
Always wear gloves, a dust mask, and safety glasses when working with refractory cement to prevent inhalation or skin contact with dry powder.
