We recommend that you use our range of Karndean Designflooring adhesives. There are five that we hold in stock for you to order.
A resin-free fibre-reinforced wet-bed high-temperature dispersion adhesive for use indoors. It’s perfect for bonding Designflooring products on most absorbent surfaces, as long as it’s level, absorbent and sound. It’s easy to apply, has good open time and “grab”, and reduces residual indentation for all round better results.
Epoxy resin is a two-part mix. Both components should be mixed together with a drill and paddle to a smooth consistency and the contents poured out within 5 minutes of mixing time. If left within the container the resin will harden inside 15 minutes; on the floor you have up to 1 hour working time. Recommended for areas subject to excessive moisture and temperature. Any areas under question consult your supplier.
NOTE: Installer must wear eye protection and gloves when using this product.
High Temperature Adhesive (HT)
A modified Acrylic adhesive with an improved service temperature. For use in areas subject to excessive heat and direct sunlight e.g. conservatories, shop windows, patio doors, external glass paneled doors and under floor heating. Dry fit floor in sections. Remove dry flooring including cuts.
DO NOT leave puddles or streaks. Place flooring into wet adhesive. Apply hand roller over newly bonded floor. Wipe any excess adhesive off flooring immediately with clean damp cloth. 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.
Special note about conservatories:
In areas that maybe subject to extremely excessive direct heat 50°C or above (e.g. fully glazed south facing
conservatories) the floor must be installed with epoxy adhesive. It is particularly necessary to keep the temperature in conservatories at a constant 18°-26° prior to, during, and for 24 hours after installation. It would also be advisable to shade windows to ensure that constant temperature conditions are maintained for 48 hours after installation.
Ideal for use in most normal residential and commercial installations. We always recommend that you work section by section, as product must be wet bonded when installed with this adhesive (the open time is approximately 15 minutes, depending on atmospheric conditions)
Pressure Sensitive Adhesive (PS)
Ideal for use in most normal residential and commercial installations. Best used as a semi-dry/tack. Once adhesive has reached the semi-dry tack condition you will have approximately 2 hours working time.
We must insist that all Karndean Designflooring products are laid using a suitable adhesive. An A2 trowel should always be used to apply Karndean Designflooring adhesives
Using the correct tools
When using our adhesives it is important to use an appropriate adhesive trowel or roller, along with the proper Karndean Designflooring adhesive.
It is possible to install Karndean products over floors incorporating underfloor heating, but these must be insulated to ensure the surface temperature throughout the installation does not exceed 80°F. The heating must be switched off 48 hours before, during, and for 48 hours following the installation, then gradually increase to working temperature.
