Bona Prime Classic 5 Litres

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.
