Karndean High Temperature Adhesive (HT)

This is a modified Acrylic adhesive with an improved service temperature. It is designed for use in areas subject to excessive heat and direct sunlight e.g. conservatories, shop windows, patio doors, external glass panel doors and under floor heating.

We always recommend that you work section by section, as product must be laid in wet adhesive. When using this adhesive, the open time is approximately 15 minutes, depending on atmospheric conditions on site.

Dry fit floor in sections. Remove dry flooring including cuts. Apply High Temperature adhesive in smooth consistent sweeps being careful not to leave puddles or streaks. Place flooring into wet adhesive. Apply hand roller over newly bonded floor. Wipe any excess adhesive off flooring immediately with a clean damp cloth.

Special note about Extreme Heat Areas:

If the area concerned may be subject to extremely excessive direct heat (50˚C or more), such as shop windows or a fully glazed south facing conservatory, then the floor must be installed with Epoxy Adhesive. It is vitally important to keep the temperature in these rooms at a constant 18˚C – 26˚C before, during and for 24hrs following installation.
It would also be prudent to shade all windows to ensure that constant temperature conditions are maintained for 48 hours after installation. For any areas under question please consult the Karndean Technical team.

Karndean recommend that you use their range of adhesives when installing their products.
