Each of these products is designed to withstand high temperatures without breaking down or deteriorating. They are also available in both a powder and liquid form, so you can use whichever is easier for you to work with. Durability factors must also be factored into selecting the right product – is your application just covering masonry joints or does it needs a ventilated cavity liner? Are chemical additives required for its expected service life? High quality basic ingredients should usually suffice but long lasting weather exposure or particularly corrosive environments may require additional steps such as waterproofing additives or specialty insulation coatings etc., The best way to avoid any potential accidents is to read and follow all of the manufacturer’s instructions that come with the product. Also be sure to have a fire extinguisher nearby in case of an emergency. 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.

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. 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. 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.
