Bona Prime Classic

Bona Prime Classic is a unique sealer especially developed to minimise ‘edge-bonding’. This term describes the gluing effect of all polyurethane finishes. Finish flows between floor board joints and prevents the boards from shrinking naturally due to changes in climatic conditions. This results in uneven gaps between boards and in some cases splitting within the boards themselves. Prime Classic is suitable for sealing most timber species with the exception of timbers containing high levels of tannin, where Prime Intense should be used, and is compatible with all Bona water-based top coats.

  • For general use and ideal for Pine and light coloured species

    Bona Classic is designed for general use but should not be used on high tannin timber species.

    Bona Classic is particularly suitable for softwood plank floors such as Pine and parquetry floors where greater movement is associated with both the species of timber and the construction of the floor.

    Bona Classic has an exceptionally low VOC content of less than 3% and is ideal for use where the aim is to keep the timber as light in colour as possible.
