Polyurethane
If you are considering a new look for your hardwood floor, there are several types of polyurethane you can choose from. The type you decide on depends on your needs and preferences. There are both water-based and oil-based options available. Both will add a rich warm color to your floors.
Water base is a great option if you are concerned about the smells that oil-based products emit. It’s also more clear. Unlike oil-based products, water-based will not alter the natural color of your hardwood floor. However, it will take more time to dry.
Oil-based polyurethane is durable and easy to clean. This is the most common finish to use on wood floors. You can find it in satin, semi-gloss and high-gloss sheens.
Depending on your needs, you can apply either two or three coats of polyurethane. Before applying the first coat, scuff sand your dustless sanding wood floors to remove scuffs, scratches, and imperfections. Once the first coat is applied, wait about 24 hours before applying the second.
When you’re finished with the second coat, let it dry for at least eight hours before applying the third. After this, you can place furniture back on your floors. Be sure to wear a respirator.
Polyurethane can be diluted with paint thinner and water. A good way to determine the thinning strength of the finish is to apply it to a small test area and wait for it to dry. For example, you can dip a rag in the finish and apply it to a spot.
To avoid brush marks, you can use an oil paint applicator. This will keep the brush from causing ridges and streaks. Also, it prevents flashing.
Oil-based polyurethanes are less expensive than water-based polyurethane. They can be used on hardwood floors and other surfaces. They have a slight amber tint. As the years pass, the color of the finish may become more saturated.
You should follow the manufacturer’s instructions for applying the polyurethane. Usually, the finish should be kept at a temperature of 65 to 80 degrees.
Acid-cured finish
An acid-cured finish is one of the most durable finishes you can use on hardwood floors. Usually, you can expect an acid-cured finish to last from 5 to 10 years. Some people also enjoy the amber patina the finish leaves behind. While this type of finish is very durable, it can be a little challenging to apply.
Fortunately, there are many options available. In addition to the popular and widely used polyurethane, you can find oil-based and moisture-cured finishes. Oil-based and moisture-cured finishes are easy to care for, and they are also resistant to scratches. The downside is that these finishes need to be re-coated about every two to three years.
Polyurethane is the most commonly used finish on hardwood floors. It is tough enough to take on constant traffic and resists yellowing. However, it is also extremely flammable. To protect yourself, you should wear a respirator and a full-face mask while applying this type of finish.
There are several other types of wood floor finishes. These include conversion varnish, shellac, and oil sealers. Each of these has its advantages. If you have a lot of traffic, you may want to consider an oil-based finish.
A water-based polyurethane sealer is easier to care for, and it is available in a variety of sheens. However, it has a strong odor, and it can be difficult to remove. For this reason, most homeowners prefer a high-gloss finish.
Moisture-cure finishes are the hardest to apply. They are available in a high-gloss or satin sheen, and they must be screened between coats. Using a broom or vacuum will help keep your floor free of dust and debris.
Conversion varnish, or “Swedish” finish, is another option. It is more expensive than other finishes, but it can last for a long time. During the curing process, the finish releases a lot of toxic fumes. This toxicity is only present for up to three days to a month, but can also cause headaches and dizziness.
Some hardwood floor refinishers recommend applying a coat of penetrating oil. Penetrating oil is a great way to bring out the grain patterns and deepen the color of your wood.
