Blue Dolphin BD77 PVC Adhesive: Thermoplastic Acrylic Adhesive for Resilient Floors

What is the Blue Dolphin BD77 PVC Adhesive?

Blue Dolphin BD77 PVC Adhesive is a one-component, thermoplastic acrylic adhesive with low water content, specially designed for installing resilient floors such as PVC on both absorbent and non-absorbent subfloors. This adhesive is ready to use and offers extended open time, allowing for more flexibility during installation. BD77 is suitable for various subfloors, including cement-based and anhydrite subfloors, with or without underfloor heating. Thanks to its thermoplastic properties, the adhesive remains flexible after curing, ensuring a durable and resilient bond that can accommodate movement in the floor without cracking or coming loose.

How the Blue Dolphin BD77 PVC Adhesive works

The Blue Dolphin BD77 PVC Adhesive works by creating a strong, elastic bond between the floor covering and the subfloor. The adhesive is applied with a notched trowel no. 1 on a well-prepared and clean surface. It is important to spread the adhesive evenly and wait at least 10 minutes for it to start drying. After laying the floor covering, even pressure should be applied over the entire surface to ensure good adhesion and to remove air bubbles. The final drying time varies from 48 to 72 hours, depending on ambient temperature and humidity. BD77 adhesive maintains its properties well when stored between +10°C and +25°C and remains stable in its original, sealed packaging for up to two years.

Advantages and properties

The Blue Dolphin BD77 PVC Adhesive offers multiple advantages, such as a long open time of 40-45 minutes at 20°C and 65% relative humidity, providing sufficient time to lay the floor accurately. The adhesive is suitable for both absorbent and non-absorbent subfloors and can be diluted with water if necessary. Another key feature is its excellent stability in storage, extending the product's shelf life to two years when stored between +10°C and +25°C. Additionally, BD77 PVC adhesive is white, which can be useful in applications where color consistency is important.

Instructions for use

For optimal results, the subfloor should be thoroughly cleaned and free of all traces of oil, grease, wax, paint stains, and other contaminants. Cement subfloors should have a maximum residual moisture content of 2.0% (or 1.7% with underfloor heating), while anhydrite subfloors should have a maximum of 0.5% (or 0.2% with underfloor heating). The Blue Dolphin BD77 adhesive is applied with a notched trowel no. 1 to the subfloor. Wait at least 10 minutes for the adhesive to start drying before laying the floor covering. After placement, even pressure must be applied to the surface to ensure complete adhesion.

Maintenance and advice

It is important to store the Blue Dolphin BD77 PVC Adhesive at a temperature between +10°C and +25°C to maintain stability and shelf life. Exposure to temperatures below 0°C should be avoided, as this can affect the quality of the adhesive. Similarly, storage above 25°C may lead to reduced stability. To ensure a long lifespan of the adhesive bond, it is advisable to maintain the correct conditions during installation and drying time, considering temperature and humidity.
