The Bona D501 is a single-component sub-floor primer. Designed to be used on the preparation of substrates before application of silane-based Bona adhesives, Bona D501 is suitable for use on absorbent and non-absorbent substrates (except for magnesium industrial floors), as well as chipboard, panels and other substrates.
Bona D501 primer binds dust and reduces the water absorption of the substrate. It should be used undiluted.
Bona recommends using the following Bona adhesives following the application of Bona D501 to the sub-floor:
- Bona R844
- Bona R845
- Bona R850
- Bona R860
|Coverage||Up to 10m² per litre|
|Drying Time||1-2 hours|
Bona D501 is suitable for use on the following subfloor:
- Cementitious screed
- Calcium sulfate screed
- Wooden substrates
- OSB or chipboard
Before using the Bona D501 sub-floor primer, the substrate must be even, totally dry, clean, free from cracks and physically sound. The surface should be slightly textured to ensure proper adhesion.
It is vital to follow the manufacturer's application instructions on the container to ensure effective use of the product. Bona recommends applying the Bona D501 sub-floor primer to the substrate using a brush or roller. After the substrate is dry, wooden floors can be installed using a Bona silane wood floor adhesive.
