Why High-Temperature Flooring Installations Need the Right Adhesive
Not every flooring project takes place in a controlled environment. In fact, many modern spaces now present a real challenge for installers – particularly areas with large glass façades, conservatories, and buildings that use underfloor heating systems.
These environments can experience significant temperature fluctuations, and that movement can put serious stress on floorcovering adhesives. When the wrong product is used, issues like lifting, indentation, or bond failure can occur over time.
That’s why selecting a high-performance adhesive, such as Ardex AF195, designed specifically for these conditions is essential.
The Challenge: Heat, Light, and Floor Stability
Luxury vinyl tile (LVT) and other resilient floorcoverings are widely used in both residential and commercial projects due to their durability and design flexibility. However, they still rely heavily on the adhesive beneath them to maintain long-term performance.
Problems typically arise in spaces where:
- Direct sunlight increases surface temperatures
- Underfloor heating creates consistent heat exposure
- Large glazed areas intensify solar gain
In these situations, standard adhesives may not provide the stability needed to maintain a secure bond over time.
A Solution Designed for Demanding Conditions
Ardex AF195 High Temperature Adhesive has been developed specifically to address these challenges.
It is a fibre-reinforced, water-based acrylic emulsion adhesive designed for LVT and other resilient floor finishes, offering strong bond performance even in thermally demanding environments.
Its formulation focuses on stability, flexibility, and reliability -making it suitable for installations where temperature exposure is a key concern.
Performance Where It Matters Most
One of the key strengths of AF195 is its ability to maintain performance under heat stress. It is designed to withstand temperatures of up to 50°C, making it suitable for areas with strong solar gain or underfloor heating systems.
Despite its strength, it still offers practical benefits on-site, including:
- Fast initial grab, allowing LVT installation in as little as 5 minutes
- Walkability in around 4 hours
- Up to 30 minutes working time for accurate placement and complex layouts such as herringbone designs
- Coverage of approximately 56m² per 12kg unit, depending on substrate conditions
Its solvent-free, low-odour formulation also makes it suitable for use in occupied buildings or sensitive environments, while its EMICODE EC1 PLUS certification ensures very low emissions.
Where It Works Best
AF195 is designed for use with a range of resilient floorcoverings, including:
- Luxury Vinyl Tiles (LVT)
- PVC sheet and tile flooring
- Rubber flooring (up to 4mm)
- Linoleum
It is particularly effective in interior dry environments such as:
- Conservatories
- Sunrooms
- Commercial spaces with extensive glazing
These are exactly the types of spaces where heat and sunlight can compromise standard adhesive performance.
Installation Considerations
As with any flooring system, preparation plays a key role in long-term success.
Surfaces should be clean, dry, and level, with a suitable damp-proof membrane in place where required. On highly absorbent substrates, priming with Ardex P 51 can help improve consistency and coverage.
Application can be carried out using a trowel or roller, and installation should always follow recommended site conditions in line with BS 8203 standards, both before and after laying.
Bringing Confidence to High-Risk Installations
In environments where temperature fluctuations are unavoidable, the adhesive becomes one of the most critical components of the entire flooring system.
Ardex AF195 is designed to give installers and specifiers greater confidence in those demanding projects – combining heat resistance, strong initial grab, and ease of use in a single solution.
For projects where reliability cannot be compromised, it offers a dependable approach to long-term flooring performance.
