Product Information

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. Make sure that all tiles are thoroughly cleaned before the grout dries. Note: This is especially important when using a rapid-setting cement-based grout such as MAPEI Ultracolor Plus FA.

Never allow the grout to remain on the surface of the tiles for an extended length of time before completing the initial cleaning. If you are using Portland cement to repair or rebuild a firebox (the part of the fireplace where you start your fires), it is important to know that Portland cement is not fire resistant. Is white Cement heat resistant? It is a common design rule that fireplaces should be the focal point any living room, common room and kitchen (if you live in the country). A fire place is a key area to dress and customise from season to season. If you were to ask most designers, it would be a pretty safe bet that they are going to work very hard to make sure that the fireplace creates a statement and draws your attention. Furnace cement is a refractory compound that can withstand temperatures up to 2000°F. It’s designed for use in gas and oil furnaces, stoves, fireplace inserts, kilns and ovens. You may also see it labeled as flue sealant or chimney sealer. It’s not to be confused with fireplace mortar which is a different material made of cement and sand.Portland cement is not fire resistant. In fact, it’s one of the most combustible materials used in construction. If you are looking for a material that will resist fire, look for a product with an “A” rating from Underwriters Laboratories (UL). Pre-cut all tiles, with the exception of the bottom row (first row) of tile on the left and right walls surrounding the fireplace. Type S mortar contains more cement than type N. This means that it is stronger but also costs more money! How do you make concrete fire resistant? No matter what type you choose, however, always be sure that you’re selecting the right grade (or density) based on the application: ASTM C270 indicates grades specifically intended for above-grade use while ASTM C1714 covers those recommended only up to four stories below grade level structures. All in all, each variation offers something different depending on your specific needs – so research carefully before investing in any particular product! Steps for Selecting the Most Suitable Mortar for Your Fireplace Furnace Cement is available in both a powder and liquid form. The powder form is mixed with water to create the cement, while the liquid form can be poured directly onto the surface that needs to be repaired.

As with any structure a good foundation is fundamental. The type and nature of foundation required will depend on the design of the fireplace surround but must be sufficient to support the entire weight of the stonework. In general, mechanical fixings between the stonework and the wall are solely for restraint purposes and should not be load bearing. In the case of cantilevered stones such as mantel shelves, the fixings should also be able to resist tipping or uplift forces. 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. It may be helpful to plan the tile placement by creating a “story pole.” To make a story pole, first lay out the tile with spacers in between each tile on a flat surface, which will represent your tiled wall (left to right = bottom to top). Then mark all tile and grout joint measurements on a long wooden dowel rod. Include decorative inserts and accent tile. Transfer the markings onto the wall surface and review the placement.Measure and mark the center points of the lower end of the mantle and the top edge of the fireplace opening. Create a line connecting these points. The intersection of the two lines marks the center of the focal point of the fireplace. 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.
