Materials such as these are commonly used for mid-to heavy-use areas because they are more durable and easier to maintain than oil sealants. Unlike the 'plastic' look of the past (Bona and Juncker), modern lacquers (Bona and Juncker) have a silky gloss, whether they are matte, satin, or high gloss.
Polyurethane lacquer is our recommended finish since it is highly resistant to wear, but it may discolour the floor underneath. Because it is not a natural substance, it may limit the ability of your timber floor to breathe.
