Product Information
Full details
Bona Intense is a professional-grade, one-component waterborne polyurethane primer designed for wood floor contractors and serious DIYers looking to achieve a medium-rich, warm tone on untreated timber. It excels at promoting strong adhesion and minimizing side-bonding, making it an ideal solution for challenging floors like those with underfloor heating or prone to seasonal movement. While it provides excellent color depth and protection, users should be aware that the final aesthetic results depend heavily on the specific wood species and sanding preparation, requiring a test patch on dense or oily woods before full-scale application.

FAQs
Can I use this on floors with underfloor heating?
Yes, Bona Intense is specifically designed to accommodate the movement of floors with underfloor heating.
How much area does one 5L container cover?
One 5L container covers approximately 50 square meters, based on a coverage rate of 10 square meters per liter.
What topcoats should I use with this primer?
This primer is intended for use with compatible Bona waterborne lacquers.
Is this primer suitable for tropical timbers?
Yes, but you must conduct a test patch first, as tropical timbers can be oily or dense, which may affect adhesion.
How long should I wait before applying the topcoat?
The primer typically dries in 1 to 2 hours, at which point the topcoat can be applied.
Will this turn the wood yellow?
Bona Intense provides a 'warm' color, which enhances the wood's natural tones rather than creating a flat yellow tint.
Troubleshooting
Primer not drying within 2 hours
Ensure the room has adequate airflow, lower the humidity levels, and ensure the temperature is above 18 degrees Celsius.
Uneven color appearance
This is often caused by an inconsistent sanding sequence. Sand the floor evenly across the entire surface and re-apply.
Poor adhesion to the wood surface
Verify that the wood was free of contaminants like wax, oil, or existing finish before application.

Setup, Compatibility & Care
Before application, ensure the timber is properly sanded and free of dust, oil, and wax. The substrate should be at room temperature, and the product should be shaken well before use. Apply the primer evenly using a T-bar or a microfibre roller.
Compatibility: Bona Intense is specifically engineered to be paired with Bona waterborne lacquers. Do not mix with non-compatible finishes to avoid adhesion failure.
Care: Store the container in a cool, dry place above 5 degrees Celsius to prevent freezing. After applying, ensure adequate ventilation in the room while the primer cures. Always perform a small test patch in an inconspicuous area to confirm the desired color depth and adhesion, especially when working with exotic or oily wood species.
