Fireplace Tile Adhesive: What Tile Adhesive To Use In A Fireplace
01/12/2024Tiling around fireplaces, especially tiling behind log burners and wood stoves, demands special care. Whether you're tiling around fireplaces, log burners, ovens/hobs, or other heat sources, our range of heat-resistant adhesives and high-quality fireboards are designed to meet various safety and building requirements and endure intense heat while maintaining structural integrity. In this guide, we consider the appropriate adhesive for a fireplace as well as any other tiling tools and materials you may need for the perfect project finish.
Is Tile Adhesive Heat Resistant?
When considering tile adhesives for fireplaces, the first question you might ask is, is tile adhesive heat resistant? The answer depends on the type of adhesive. Most standard tile adhesives are not designed for prolonged exposure to high temperatures and may crack, lose adhesion, or even fail entirely when used near fireplaces or behind wood stoves. For areas exposed to significant heat, such as tiling behind wood stoves or log burners, heat-resistant tile adhesive is essential. These specialised adhesives are formulated to maintain a secure bond even when subjected to intense thermal conditions.
The renowned Kerakoll H40, Mapei Keraflex, Ultratile Proflex S2, Benflex, and Weberset SPF S1 are all options from our selection of heat-resistant tile adhesives that provide great adhesion and long-lasting results in areas exposed to elevated temperatures, such as if you need heat-resistant tile adhesive for a fireplace.

Is Tile Adhesive Heat Proof?
The term "heat proof tile adhesive" often creates confusion. Many assume it refers to an adhesive that can create an impenetrable barrier against fire, but this isn’t the case. In reality, quality tile adhesives can be heat resistant tile adhesive, meaning they can withstand exposure to heat, such as being suitable to be used around log burners, but not open fires, without degrading. However, they cannot provide an absolute heat-proof guarantee. This is an important distinction to make when planning your tiling project, as relying on the adhesive alone for heatproofing would lead to issues down the line.
Can You Use Normal Tile Adhesive for a Fireplace?
While it might be tempting to any regular tile adhesive for a quick DIY project, it’s not advisable for areas exposed to high heat. Regular tile adhesives can soften or deteriorate under extreme temperatures, leading to loose tiles or worse—potential fire hazards. Instead, opt for heat-resistant tile adhesives, which are specifically formulated to handle the unique challenges of high-temperature environments, including thermal expansion and prolonged exposure to heat.
Is Mapei Tile Adhesive Heat Resistant?
Mapei is a trusted name in the tiling industry, but much like most brands, not all Mapei tile adhesives are heat resistant. For fireplace applications, it’s crucial to select a Mapei product designed for high-temperature environments. Always check the product’s specifications or consult with a professional to ensure you’re using the right adhesive for your project. If you’re looking for a heat-resistant Mapei tile adhesive, the Mapei Keraflex Maxi High-Performance Low Dust Standard Set Flexible S1 Adhesive is our recommended choice.
Tiling Behind Log Burners and Wood Stoves
Fireplace tile adhesive is just one part of the equation when tiling behind log burners or wood stoves. The surface behind these heat sources must also be fire-resistant. Here’s a quick guide to ensure your project is both safe and long-lasting:
Tiling Safety Gear: Always remember personal protective equipment. A high-quality dust mask, safety glasses, and work gloves are important when working with adhesives and mixing tools. Prioritise your safety to ensure a worry-free working environment.
Surface Preparation: Start with a non-combustible surface. If the wall is not already heat-resistant, you’ll need to install a fireboard.
Fireboards: Fireboards are a crucial component for creating a safe backing for tiles in areas exposed to extreme heat. These boards are designed to resist high temperatures and provide a stable base for your tiles. Once the fireboard is installed, you can safely apply tiles using heat-resistant adhesive.
Tile Selection: Choose tiles that are heat-resistant, such as ceramic, porcelain, or natural stone.
Heat-Resistant Tile Adhesive Application: Apply the adhesive evenly with a notched trowel, ensuring a strong bond that can withstand heat.

What Is Fireboard?
Fireboard is a specialised tile backer board that has a gypsum core and contains glass fibres and other non-combustible materials. We stock fireboards in various thicknesses, including the popular 20mm fireboard, 50mm fireboard, and 100mm fireboard, to suit different installation needs. Our range includes the popular Marmox insulation boards, providing excellent thermal and acoustic insulation properties alongside fire protection.
