BFC Black Fire Cement - Fireplace Sealant
VITCAS BFC - Black Fire Cement is a smooth paste that sets rock hard when exposed to air. It offers excellent adhesion to materials such as fire bricks, blockwork, stone, clayware, and most metals. VITCAS BFC black fire cement is ideal for minor repairs, sealing cracks under 5mm, and forming smoke and gas-tight joints. Resistant to high temperatures up to 1250°C / 2280°F
Uses:
Sealing metal-to-metal joints
Sealing joints between internal flue pipes and stoves, in combination with stove rope
Firebrick repairing and Firebacks' seals
Fine joints, and small repairs on fireplaces, ovens, boilers including other components of central heating systems.

Instructions:
Ensure the area is clean and free from dirt, dust, rust, and grease.
Cut off the top of the cartridge, attach the nozzle, and trim to the required size.
Dampen the surface where the cement will be applied.
Use a cartridge gun to apply the material.
The fire cement will set at room temperature, but the process can be sped up by gradually applying heat over a four-hour period.
After curing, fill any fine cracks with additional fire cement to maintain an airtight seal.

Very good product
ByDr Brian Smith
Used it seal a crack in the fire wall and around fire surround. It's a bit runny. So I would advise to mask of any area's that you don't want the paste to go. As it will stick to anything.

Excellent product
ByVern
Used this for the first time to reseal my woodburner instead of cement in a tub. It is easier to use and a lot less messy. I also believe the shelf life after opening is much than a tub which dries out very quickly.

A top quality product
ByRoger
This black fire cement, especially when used with soft rope packing, makes an excellent seal between the stove collar and the flue pipe on my Little Wenlock multifuel stove. I have also used it in the same way to make the joint between the flue pipe and the closure plate where it passes through the concrete lintel.
The product is straightforward to use and is exceptionally good value. It has a long shelf life compared with other leading brands of fire cement supplied in tubs.
Unbeatable!

ByRich
This product was easy to apply and gave a good professional looking finish. As I haven't needed to light my log burner since applying it, I can't comment on whether it will be durable but I am confident it will work as described. I would happily recommend this cement.

Product FAQs
Question
What repairs is VITCAS BFC suitable for?
Answer
VITCAS BFC Black Fire Cement - Fireplace Sealant is intended for fine joints, minor repairs and sealing cracks under 5mm. Typical applications include fireplaces, wood-burning stoves, ovens, boilers, fire bricks and firebacks. It forms hard, smoke- and gas-tight joints when correctly applied, but larger gaps or structural repairs may require a different refractory repair product.
Question
Which materials will this BFC sealant adhere to?
Answer
The BFC sealant adheres to firebricks, blockwork, stone, clayware and most metals. This makes it useful where a heat-resistant seal or small repair must join different materials around a stove, fireplace or heating appliance. The surfaces must be clean, suitably prepared and lightly dampened before application.
Question
Can it withstand temperatures inside stoves and fireplaces?
Answer
The VITCAS BFC is resistant to temperatures up to 1250°C. It is suitable for confirmed applications such as multi-fuel or wood-burning stove assembly, fireplace repairs, firebrick repairs and joints around internal flue pipes.
Question
What should I use on the first joint between a stove and flue pipe?
Answer
Use VITCAS BFC Fireplace Sealant to seal the first joint between the stove outlet and the internal flue pipe. Apply it with stove rope where required to create a heat-resistant, smoke- and gas-tight seal. Ensure the joint is clean, free from rust, dust and grease, and lightly dampened before application.
Question
Why has VITCAS BFC turned white after installation?
Answer
White discolouration can occur when newly applied BFC Black Fire Cement remains unheated, particularly in a damp atmosphere. Moisture dissolves soluble salts within the cement and carries them to the surface, where they form a white deposit as the moisture evaporates. To reduce this effect, keep the installation dry and gradually apply heat over approximately four hours in accordance with the application instructions.
Question
How should VITCAS BFC be dried and cured?
Answer
Allow VITCAS BFC Black Fire Cement to dry for 4–5 hours at +20°C. It will set at room temperature, but curing can be accelerated by gradually applying heat and maintaining a temperature above +100°C for 12 hours. Once cured, inspect the joint and fill any fine cracks with additional fire cement where necessary to maintain an airtight seal.
Question
What should I use to reseal a cast iron stove?
Answer
Use VITCAS BFC Fireplace Sealant to reseal rigid joints between cast iron stove components. Remove old sealant, rust, dust and grease, then lightly dampen the surfaces before applying the BFC sealant. For fireplace / stove doors or glass panels that require a flexible seal, use the correct stove rope and rope adhesive instead.
