Product Information

Fire cement or furnace cement is a refractory sealant, used to create sealing joints in fireplaces and wood-burning stoves, as well as kilns. This material is designed to withstand high temperatures of up to 1200 ° C while maintaining its elasticity. Fire cements are commonly used in metalworking industries such as foundries, forges and metal casting plants.

As part of the renovation of this 18th century cottage, the owners carefully uncovered and restored the original Bath stone fireplace — it is now their favourite feature.

Allow the area to dry until the mortar achieves its initial cure and the tile becomes solidly bonded.The choice of aggregate will depend on the type, colour and texture of the stone and may include sand or stone dust. For example, for soft limestones the best aggregate is stone dust produced from the same type of stone as that being fitted and, preferably, with the addition of lime to the mix. Sandstones are best bedded on a sand and cement mix using a suitably coloured sand to match the stone. The coarseness of the aggregate will depend on the texture of the stone being used. For harder limestones and stones that take a polish, such as marbles and granites, it may be more suitable to use an appropriately coloured proprietary adhesive. Apart from this, professionals also recommend cleaning all surfaces from dust, grease, oils, and other contaminant substances. You should take a step further and wet all the surfaces before applying the fire putty. How Long for Fire Cement to Dry?

Another way to make concrete fire resistant is to use a higher-quality cement. This will help keep the concrete from melting or crumbling in the heat of a fire. When choosing the best furnace cement for your application, consider the type of cement, the temperature rating, and the price. By considering these factors, you can choose the right furnace cement for your needs. One way to make concrete fire resistant is to add a retardant to the mixture. This will help reduce the amount of heat that is transferred from the fire to the concrete. There are many different types of retardants available, so you can choose one that works best for your project. Do not let any unnecessary putty to dry out on the surfaces of the stove or flue pipe. This excessive fire cement can become incredibly difficult to remove later on.

Clean the area where you will be installing the furnace cement. Make sure there is no dirt, dust, or debris. Never allow the grout to remain on the surface of the tiles for an extended length of time before completing the initial cleaning. Gaining insight into these distinctions can assist you in customizing your preventive measures. DIY Assessment and Safety Measures It is suitable for all kinds of INTERIOR use, but must not to be used outdoors, unless it is protected from water by a roofed area or an additional render coat with a different material. Pre-cut all tiles, with the exception of the bottom row (first row) of tile on the left and right walls surrounding the fireplace.

Apply another thin layer of cement to the inside surface of the chimney liner. This will ensure a tight fit between the two pieces. The use of adhesives to bond stone fireplace surrounds to walls is not recommended as they are not sufficient on their own to provide a guaranteed secure bond throughout the lifetime of the fireplace surround. Where walls have been painted there may be inadequate adhesion between the paint and the surface below. Where bonding to plaster there will always be a risk of the fireplace surround becoming unstable should a failure of the plaster occur. The use of mechanical fixings eliminates these risks. Silica fume: This is a very fine powder that is created when the silicon in sand is heated to very high temperatures. It helps to increase the strength and durability of concrete, and it also makes it more resistant to heat. There is currently no British Standard for the fixing of stone fireplace surrounds. The fixing of stonework is covered by BS 8298 “Code of Practice for Design and Installation of Natural Stone Cladding and Lining”, and BS 5628 “Code of Practice for use of Masonry – Part 3: Materials and Components, Design and Workmanship”. While these may provide some useful guidance they are not specific to the installation of stone fireplace surrounds. If you suspect that there is an old fireplace hiding behind one of your walls then you will no doubt be eager to set it free — opening up a fireplace is a job that can add value and charm to a home.These should be chosen to suit the type and colour of the stone, and the size and weight of the individual units. Ideally the pointing should match the colour of the stone. For fireplace surrounds formed of solid stonework, where a good mortar bed is particularly important, mortars should consist of an aggregate and cement. The objective is to produce a mortar of the same hardness as the stone. Fire Cement is a ready and mixed combination of thermosetting resins and inorganic fillers. When applied and exposed to high temperatures, this combination is capable of healing, which results in a mortar. This mortar is temperature resistant up to 1250ºC.
