Floor Finishes

There are many ways in which the surface of your hardwood floor can be finished, below are described some of the properties and differences of these floor finishes:

1. Oil-modified urethane is generally the most common surface finish and is easy to apply. It is a petroleum base with a blend of synthetic resins, plasticizers and other film forming ingredients that produces a durable surface that is moisture-resistant. It is a solvent-base polyurethane that dries in about eight hours. This type of finish ambers with age. and comes in different sheen levels.

2. Moisture-cured urethane is a solvent-base polyurethane that is more durable and more moisture resistant than other surface finishes. Moisture-cure urethane comes in non-yellowing and in ambering types and is generally available in satin or gloss. These finishes are extremely difficult to apply, have a strong odor and are best left to the professional.Curing of this type of finish is by absorbing minute quantities of moisture vapor from the air, which causes them to dry and harden. The curing process is very dependant on relative humidity.

3. Water-based urethane is a water-borne urethane with a blend of synthetic resins, plasticizers and other film forming ingredients that produces a durable surface that is moisture-resistant. These finishes are clear and non-yellowing and are different sheen levels. They have a milder odor than oil-modified finishes have and they dry in about two to three hours. Water-based urethanes are generally more expensive.

4. Converstion-Varnish Sealers-(Swedish Finishes)- A two-component acid-curing, alcohol-based sealers. Because of their origin (country), conversion varnish sealers are often referred to as Swedish finishes.

5. Penetrating Sealers – These sealers are spread on the floor and allowed to penetrate and are solvent based. The excess sealer is removed with rags or buffed in with synthetic or steel wool pads. This type of finish often have a color and can be used to stain and seal the wood floor. Penetrating Oil Sealers are made from tung or linseed oil, with additives improve drying and hardness.

6. Paste Wax– The oldest, and in some ways the best. Wax is the easiest to apply, least expensive, fastest drying, easiest to repair, and with proper care will survive forever. Wax over a penetrating stain, and the system is in the wood so you wear the wood, not the finish. Wax is spread in thin coats for a surface protection after the stain and/or sealer is applied, then buffed to the desired sheen.

7. Varnish– Vinyl-alkyd varnishes have superseded natural varnish made from vegetable oils. This product was commonly used before urethane finishes where introduced.

8. Lacquer – The flammability and incompatibility of this floor finish is NOT a recommended by many manufacturers. This finish should avoided.

9. Shellac – This product (natural shellac) contains wax and is not widely used for top coating in today’s wood flooring market. Dewaxed shellac is becoming used more and more for a wood floor sealer.
