What are the types of paint for wood?

Hard wax oils are a practical solution for giving stressed floors a fresh appearance, making wooden surfaces dirt and water repellent, and preserving old pieces of furniture.

Due to their ingredients based on vegetable oils and waxes, solid wax oils are very well tolerated and in most cases suitable for allergy sufferers. Many products are also suitable for the treatment of wooden children’s toys.

There are several types of wood preservative:

  • Solid wax oils for the treatment of new surfaces.

They have a very high glaze resistance, the complete hardening takes between 1 and 10 days. Partially suitable for children’s toys, partially saliva and perspiration resistant, a small selection of different colors.

  • Solid wax oils for the treatment of pre-treated surfaces.

They have a very high glaze resistance, complete curing takes 1 to 10 days. Partially suitable for children’s toys, partially resistant to saliva and perspiration, have a rich color palette.

  • Solid waxes for the repair of small objects.

They have a highly resistant glaze, full curing takes 7-10 days. Great for children’s toys, saliva, and sweat-resistant, available in a variety of colors.

Wood preservative for your purposes

Looking to treat a new hardwood floor for the first time or touch up a discolored countertop? You can find the right oil for a variety of purposes.

  • Hard wax oil for primary treatment of large areas.

Fast curing and high performance: kerosene oil for priming large surfaces.
With a hard wax oil, you can enjoy your parquet and other natural wood floors longer. Whether you’re touching up an old floor or treating your freshly installed floor for the first time, hard wax oil will prevent the wood from quickly becoming rough and discolored.

Although all oils are suitable for initial treatment, when purchasing, make sure that the oil you choose can be used on floors that have already been treated.

You will also need to purchase a sufficient amount when treating a floor: At least one quart of hard wax oil should be budgeted for an area of 215ft², and more for larger areas. On average, 1.0 to 1.7 fl oz of solid wax oil is needed per square foot.

If you plan to use the room again in the near future, you should also make sure that the curing time is as short as possible. Depending on the material and manufacturer, this can take anywhere from 1 to 10 days. Crucial are the operating temperatures, ideally between 54℉ and 77℉, as well as sufficient ventilation.

Solid wax oil can usually be stored for several years in a dry and cool place. Since surfaces often need to be oiled several times, it is advisable to buy up to 85us fl oz.

  • Hard wax oil for repairing furniture and small areas.

Unlike large area treatments, you don’t have to buy an ounce or more of hard wax oil for smaller wood items. Some manufacturers, offer hard wax oil in smaller quantities – 6.8us fl oz.

If you are working directly with treated objects, compatibility is even more important. If you want to treat wooden toys, we recommend wood preservatives with vegetable oils such as sunflower oil and wax, which are saliva resistant and repellent. It is important that toys and other objects are not only harmless when in contact with mucous membranes, but also do not come into contact with saliva and sweat.

While colorless and silk matt hard wax oils are recommended for the treatment of large surfaces, there are also oils in various shades, such as cherry or walnut, which can be used especially for the refurbishment of stained wood.

What should you look for when buying the wood preservative?

Which wood preservative is the best? There is no universally valid answer to this question. Wood preservative paint tests have been searched in vain so far. However, there are some criteria by which you can choose the best wood preservative.

When buying should pay attention to the following:

  • Opacity.

Wood preservative paint is usually used to paint larger areas. This can be seen from the fact that the standard size of the containers is also larger: 85us fl oz, but also 3US gal lqd or even 2.6US gal lqd are offered. The first criterion to pay attention to when buying wood preservative paint is, therefore: how many square meters can be painted with it? 3.4us fl oz of a good weather protection paint for wood should be enough for one square meter, sometimes even a larger area is possible. Paints that are less efficient must have special other qualities to compensate for this shortcoming.

Since most wood preservative paints are now water-based, they can also be diluted with water – and consumption can be reduced in this way. To do this, however, be sure to pay close attention to the manufacturer’s instructions whether this is possible. Products based on natural oils or resins cannot be stretched in this way.

While water can be added to the first or second coat without hesitation, the final topcoat should be applied undiluted in order to maintain full protection against sun and moisture.

  • The price-performance ratio.

The yield of the wood coating is one thing. However, this value in the purchase advice is only really informative when it is put in relation to the price. It is obvious that of two paints that cover equally well, the one for which I have to pay less for the same quantity is always more attractive.

There are now also manufacturers who achieve acceptable values and offer inexpensive paint for wood. However, the buyer may have to pay about five times as much to work on the same surface.

  • Primer.

If the wood surface is completely untreated or already has an older coat of paint on it, it may be necessary to apply a primer. Otherwise, the old paint will show through or substances from the wood will penetrate the paint, changing the color tone or even hindering the effect of the wood preservative.

However, some wood preservative paints – so-called 2in1 products – serve as a primer and topcoat. So nothing else needs to be purchased here. For other wood coatings, it depends on the substrate: Only for individual types of wood – for example, softwoods – an extra primer must be purchased, because these materials give off special substances. In most cases, manufacturers offer a matching primer for the topcoat.

What are the best tips for applying wood preservative?

  • Use only white or beige attachments for the polishing machine, so as not to get unwanted color gradients.
  • Treated hardwood floors can be damaged by moving heavy furniture. A felt glider under tables and chairs will prevent abrasion.
  • In order for the hard wax oil to be absorbed even better by the wood, you can stain it beforehand. To do this, spread the stain on the surface and let the solution dry well.
  • If you want to treat cork, balsa, end grain, or burnt brick, you should plan on using about 30% more hard wax oil than for wood, since these are highly absorbent substrates. Expect to use 1.7us fl oz to 2.4us fl oz per square foot.
  • Avoid standing water on your sealed wood floor as it will affect the protection provided by the hard wax oil.
  • Since hard wax oil is highly flammable, it should not be stored in a boiler room. Store the oil in a cool, dry, and well-ventilated area.

Parquet floors, wooden doors, and stairs lose their shine and show signs of wear over time. Treatment with hard wax oil is recommended as the initial treatment of freshly laid wooden floors so that the rough wood shines again.

Wait for the oil to fully cure before using furniture and floors. Depending on the brand and manufacturer of the hard wax oil, this can take up to 10 days. Only clean rooms with a broom or vacuum until it has cured.

Many hard wax oils are also suitable for other surfaces such as terracotta, cork, and stone tiles.
Hard waxes are made from biological ingredients such as vegetable oils and waxes. Its compatibility passes even the toughest allergy tests. Hard wax oil can be used to restore the surfaces of wooden floors and furniture. Thanks to its ease of use, this method of wood care, which is also suitable for allergy sufferers, is becoming increasingly popular.

FAQs- The Best Option Wood Preservative

✅ Can you remove the hard wax oil again?

If you have accidentally applied too much oil with the result that the surface is now sticky, orange peel oil can remedy the situation. Apply this thinly to the floor and use a polishing machine to completely loosen the coating from the floor. Now you can apply a thinner coat of hard wax oil again.

If in doubt, do the test on a small area by applying some hard wax oil and removing it after polishing. If the floor continues to stick after removing the oil, reduce the amount used by half and apply a new trial coat.

✅ Which is better - hard wax or hard oil?

In addition to hard wax oil, hard oil is also commonly used in wood care. While the solid wax oil category is an oil-wax combination based on resins, vegetable oils, and wax, there is no way in solid oil. Solid oil is also a vegetable product based on sunflower oil, safflower oil, linseed oil, and others.

The main difference is that solid oil soaks into the wood more and protects it from moisture, but does not provide adequate surface protection due to the lack of wax. Solid wax oil creates a glossy effect while using the solid oil type creates more color intensity or darkens the wood even more.

Solid wax oil thus provides double protection with oil and wax. Before sealing the surface of the material with wax, it makes the oil more resistant. This also eliminates the need to buy furniture wax.

✅ What is pressure treatment of wood?

It is a process used to preserve wood using chemicals. They help kill wood-boring insects, microorganisms, and fungal decay. This process works with softwood.

✅ How do I apply hard wax oil to wood?

A mouthpiece and gloves should be worn before starting work.

Proceed as follows:

When treating floors, start in the corner farthest from the door.
When treating small surfaces and furniture, start at the corners or edges. Apply an even coat of oil, always brushing and rolling out completely. In between, make sure the oil is evenly applied everywhere.

One of the most common mistakes when applying with a brush is to apply short strokes with the brush. For an even finish, always stroke with the brush and work in the direction of the texture movement so that the wood pores can fully absorb the oil.

For intensively used surfaces and objects, it is advisable to apply a second or third coat of oil, but for this, the surface must be polished first.
