Frequently Asked Questions
What are the dangers associated with solvent-based finishes?
Toxic fumes given off by solvent floor finishes contain free isocyanates that affect the respiratory system and are particularly dangerous for asthma sufferers, children and the elderly. Solvent-based floor finishes are classified as poisons and homeowners should vacate premises until solvent based coatings are fully cured. This can take a minimum of 7 – 14 days. In addition the fumes from solvent finishes can taint food in pantries and even refrigerators. Some water based paints can turn yellow due to the reaction of isocyanates with the amines in the paint. Plants, paintings and pets should also be removed from the area until the finish is totally cured.
Alternatively choose the convenience of a non-toxic waterborne floor finish. No toxic fumes or isocyanates - so no need to move out! Bona’s modern polyurethane finishes offer excellent wear resistance, are non-yellowing and bring out the real beauty of timber flooring - without risking your health. Solvent finishes are a thing of the past, so ask your professional floor finisher about the benefits of the Bona waterborne alternative.

Don’t solvent-based finishes wear better?
20 years ago the answer was yes. Today’s technology means that the best waterborne finishes are 100% polyurethane and provide wear resistance that is better or as good as solvent based products - without the toxic fumes. Floors in commercial premises are routinely coated with waterborne finishes as there is minimal disturbance to the commercial operation with no toxic fumes or health risks. In these situations having good wear resistance is a necessity.

What advantages do Bona finishes offer?
Bona non-toxic waterborne finishes offer many advantages over solvent-based products. Firstly all Bona finishes are classified as non-toxic and there is no need to move out while the finish is curing. This usually takes between 7 and 14 days. Bona finishes are non-yellowing, fast drying and have excellent resistance to wear. There is also a choice of sheen levels ranging from absolute matt, matt, satin through to gloss. Unlike solvent finishes that give floors a plastic appearance, Bona finishes look more natural and highlight the beauty of the timber.

Are waterborne finishes more expensive?
The difference in product cost between using a waterborne finish and a solvent finish is usually about $4 - $6 per m². Compare that with the many benefits of a non-toxic Bona finish. For example, no need to move out while the finish is curing. Depending on climatic conditions this can take between 7 to 14 days and even longer. All Bona finishes are also non-yellowing, fast drying and have excellent wear resistance.

Why use a sealer or primer?
Although Bona top coats can be used directly on bare timber, we strongly recommend the use of Prime Classic or Intense. Firstly, you save money because a primer costs less than a top coat. Apart from savings there are sound technical reasons to use a primer. Bona Classic or Intense ensure the floor has an even look without discolouration or a patchy appearance. You also save time because both products dry faster than top-coats.

How do I maintain my floor?
There are some simple steps to maintaining a timber floor. In short, try to prevent the floor getting dirty by using preventative measures such as mats, clean up spillage as soon as possible, use the minimum amount of moisture on the floor and refurbish the floor by re-coating the floor with a single application of finish when required.

How do I find a good contractor?
Finding a contractor to undertake any building work can be a daunting task. Word-of-mouth recommendations are always good but if this is not possible there are a few basic guidelines for engaging a contractor:-
Get more than one price, even if it is just over the phone. That way you can be sure you are not being over-charged.
Make sure you obtain a detailed quotation in writing detailing all the work to be carried out. Clarify the little things such as, “will the rubbish and sawdust from the floor be removed from site”?
Ask the contractor for references that you can contact if you choose to. Good contractors are only too happy to have the chance to let you speak to happy customers.
Beware of someone who asks for money up front and make sure you are happy with the end result before making final payment. Stage payments may be used where timber flooring is laid and finished after each phase of work is completed but again make sure you are happy before signing off each stage.
This website includes a list of floor finishing companies and contractors who have used Bona products regularly over a period of time –
See Finding Your Contractor. This is to aid you finding tradesmen familiar with Bona waterborne finishes. This list should not be seen however as approved contractors as with the size of our country it is not possible to maintain an effective approval scheme. Ultimately the decision is yours and you should ensure, by taking testimonials and your discussions with the contractor regarding the works to be undertaken, that you have chosen wisely.
