Bona D501 Adhesive Primer is a solvent-free primer and dust binder designed to prepare suitable absorbent and non-absorbent subfloors before the installation of wood flooring using Bona silane adhesives.

Fast drying and easy to apply, Bona D501 helps improve adhesion, binds residual surface dust and can normally be overcoated with Bona silane adhesives after approximately one hour under normal site conditions.

Why Choose Bona D501?

Suitable for absorbent and non-absorbent subfloors
Binds residual dust before adhesive application

Easy roller or brush application
Suitable before Bona silane adhesives

Suitable Substrates

Bona D501 is suitable for preparing correctly assessed subfloors including:

Concrete and cementitious screeds
Calcium sulphate screeds
Chipboard panels
Suitable absorbent subfloors
Suitable non-absorbent subfloors

When should you use Bona D501?
Bona D501 is designed to improve adhesion and bind residual dust before applying Bona silane adhesives. Where moisture suppression is required, consider Bona R540 Primer & DPM instead.

Application

Ensure the subfloor is clean, dry and structurally sound.
Remove loose dust, debris and contaminants.
Apply Bona D501 evenly using a roller or brush.

1. **What is Bona D501 glue primer used for?**
**Answer:** Bona D501 is a water-based primer designed for use before applying Bona adhesives. It helps improve the adhesion of Bona silane-based adhesives on absorbent and porous surfaces, such as concrete and other subfloors.

2. **How do I apply Bona D501 primer?**
**Answer:** Bona D501 can be applied using a roller or brush in a thin and even layer. Ensure the surface is clean, dry, and free of dust before application. Allow the primer to dry completely (approximately 1-2 hours) before applying the adhesive.

3. **Can I use Bona D501 on non-porous surfaces?**
**Answer:** No, Bona D501 is intended for porous and absorbent surfaces only. For non-porous surfaces, it's recommended to use Bona R540, which is specifically designed for such applications.

4. **How long does Bona D501 take to dry?**
**Answer:** Under normal conditions (20°C and 60% relative humidity), Bona D501 takes approximately 1-2 hours to dry. However, drying times can vary based on temperature, humidity, and ventilation.

5. **Do I need to dilute Bona D501 before use?**
**Answer:** No, Bona D501 is ready to use and should not be diluted. Simply stir the product well before application.

6. **How much coverage can I expect from Bona D501?**
**Answer:** Coverage varies based on the porosity of the surface, but on average, you can expect around 5-10 square meters per liter.

7. **What surfaces are compatible with Bona D501 primer?**
**Answer:** Bona D501 is suitable for porous surfaces like concrete, cementitious screeds, and other absorbent subfloors. It should not be used on non-porous materials.

8. **Is Bona D501 environmentally friendly?**
**Answer:** Yes, Bona D501 is water-based and low in VOCs (volatile organic compounds), making it more environmentally friendly and safer to use compared to solvent-based primers.

9. **What precautions should I take when using Bona D501?**
**Answer:** Ensure the area is well-ventilated during application. Avoid skin and eye contact, and wear protective gloves and eyewear. Refer to the product’s safety data sheet for more detailed precautions.

10. **How should Bona D501 be stored?**
**Answer:** Store Bona D501 in a cool, dry place, away from direct sunlight and frost. The product should be kept in its original container with the lid tightly closed when not in use.
