Bona R848 is a professional-grade, hard-elastic, one-component silane wood flooring adhesive designed for the fully bonded installation of engineered wood flooring, engineered parquet and other dimensionally stable wood floors.

Its strong initial grab and excellent rib stability help hold flooring securely during installation, while its elastic bond reduces stress transferred between the timber and the subfloor. Bona R848 can also be used with suitable solid wood boards up to 190mm wide, subject to the flooring manufacturer's installation requirements.

View our Bona glue trowels to select the correct notch for your installation.

Suitable Subfloors

Bona R848 may be used on correctly assessed and prepared subfloors including:

Cementitious screeds compliant with EN 13813
Calcium sulphate screeds compliant with EN 13813
Suitable timber subfloors
V100-grade chipboard
Compatible levelling compounds applied at the required thickness
Other dry, sound, stable and suitably prepared subfloors

Browse our floor levelling compounds and floor preparation tools before installation.

Subfloor Preparation

The subfloor must be dry, sound, clean, level and free from dust, grease, laitance, loose material and anything that could affect adhesion. Existing coatings, adhesive residues and contaminants must be assessed and treated appropriately before installation.

Check the subfloor moisture level and confirm that it is within the limits required by Bona, the wood flooring manufacturer and the relevant British Standards. Uneven areas should be mechanically prepared and levelled using a compatible flooring system where required.

Application

Allow the adhesive and flooring to reach a suitable installation temperature.
Confirm that the subfloor is dry, sound, level and properly prepared.
Spread Bona R848 evenly using the appropriate notched trowel.
Only apply as much adhesive as can be covered within the stated open time.
Place the flooring into the wet adhesive and press firmly to achieve full transfer.
Check regularly that the back of the flooring is receiving sufficient adhesive contact.
Remove fresh adhesive contamination immediately using a suitable cleaning method.
Avoid loading or heavily trafficking the installation for approximately 24 hours.

Important: Always read the current Bona Technical Data Sheet and the flooring manufacturer's installation instructions before use. Installation conditions, subfloor moisture, board dimensions and floor construction can affect product suitability.

1. What is Bona R848 Wood Flooring Adhesive used for?

Bona R848 is a silane-based, flexible wood flooring adhesive designed for bonding wooden floors to a wide range of subfloors. It provides a strong, elastic bond, allowing the wood to move naturally with changes in temperature and humidity without compromising the adhesion.

2. How do I apply Bona R848 Wood Flooring Adhesive?

Bona R848 should be applied using a notched trowel. Spread the adhesive evenly on the subfloor, and then place the wooden flooring directly into the adhesive. Press the boards down firmly to ensure good contact. Follow the manufacturer's recommendations for trowel size and application techniques for best results.

3. How long does Bona R848 take to cure?

Bona R848 typically cures within 24-48 hours, depending on the temperature, humidity, and type of subfloor. It is recommended to avoid walking on the floor until the adhesive has fully cured.

4. What types of flooring can be installed with Bona R848?

Bona R848 is suitable for use with most types of wooden floors, including solid wood, engineered wood, and parquet. It is highly flexible, making it ideal for larger planks and floors in areas prone to significant temperature changes.

5. Can Bona R848 be used with underfloor heating?

Yes, Bona R848 is suitable for use with underfloor heating systems. Its elastic properties allow the wood to move slightly without damaging the bond, making it ideal for environments with fluctuating temperatures, such as those with underfloor heating.

6. Is Bona R848 environmentally friendly?

Yes, Bona R848 is solvent-free and contains very low levels of VOCs (volatile organic compounds), making it an environmentally friendly and safe option for indoor use. It is GREENGUARD certified, meeting stringent standards for indoor air quality.

7. Can Bona R848 be used on old floors with bitumen or adhesive residue?

Bona R848 can be used over subfloors with some adhesive residue, but it is important that the residue is stable and firmly bonded to the subfloor. For bitumen or other types of old adhesive residue, it is recommended to use a suitable primer, such as Bona R410, before applying Bona R848.

8. What is the advantage of using a silane-based adhesive like Bona R848?

Silane-based adhesives like Bona R848 provide excellent flexibility, allowing for natural movement of the wood floor due to changes in temperature and humidity. This reduces the risk of cracks, lifting, or damage to the floor, while maintaining a strong bond with the subfloor.

9. How do I clean up after using Bona R848?

Any excess adhesive should be removed immediately using a damp cloth or Bona Cleaning Wipes. Once dried, the adhesive can be difficult to remove, so it’s important to clean up any spills or excess during the application process.

10. How should Bona R848 be stored?

Store Bona R848 in a cool, dry place, away from direct sunlight and frost. Ensure the container is tightly sealed when not in use to prevent the adhesive from curing inside the tub.
