Concrete is not a flammable material. While it may not be entirely immune to fire and fire damage, it is not as likely to catch fire as a wooden structure. The lack of flammability is one of concretes biggest pluses, and it is also the reason many fireplaces are made out of brick. Brick is a type of concrete, albeit slightly more delicate and significantly more porous. The imperviousness to flame makes brick an attractive choice for someone looking to build and install a fireplace, whether indoor or outdoor. Concrete fireplaces are becoming more popular and it is an excellent idea to seal them before use.

Best Sealer for an Indoor Fireplace

Fireplaces are wonderful areas for gathering around as a family or as a group of friends, as fires provide the communal sense of trust, comfort, and relaxation that helps provide a pleasing aesthetic and physical atmosphere for an evening of bonding. Concrete, brick and stone have long been the preferred material used to construct fireplaces; while these materials are well known for their strength, durability, and longevity, they need a little help to reach their maximum potential. However, the one step homeowners commonly forget to take is that of sealing their fireplaces. Fireplaces often are exposed to myriad sources of wear that can degrade and corrupt its visual and structural integrity.

To treat indoor fireplaces we recommend the Siloxa-Tek 8500. The Siloxa-Tek 8500 is our most versitile product that can be used on concrete, brick, stone or masonry based substrates. It will protect the surface of your fireplace from water infilitration, mold and mildew growth and efflorescence. Leaving a natural finish, the beauty of the natural concrete, brick or stone will shine and be the centerpiece of your fireplace.

Best Sealer for an Outdoor Fireplace or Fire Pit

Outdoor fireplaces and firepits are great gathering spots for families and friends, helping to provide a pleasing aesthetic and physical atmosphere for a night of bonding. Many fireplaces are increasingly being constructed from concrete, due to that materials excellent properties of strength, durability, and longevity. However, one step many homeowners are forgetting is to seal their outdoor fireplaces. Concrete outdoor fireplaces are located directly in the elements with no reprieve from the rain, snow, or other such sources of wear that can degrade and corrupt your concrete over time. While outdoor fireplaces are not integral to the structural integrity of your home, you certainly do not want to have to replace the fireplace constantly due to preventable damage.

For outdoor fireplaces where a natural finish is desiered we woudl also recommend using the Siloxa-Tek 8500. If a high gloss, wet look or decorative finish is desired we would recommend using the Cryli-Tek 5505. The Cryli-Tek 5505 will add a beautiful decorative sheen to concrete, paver and stone fireplaces enhancing the colors and textures of the substrate.
