Types of wood varnishes

Wood varnishes have different properties and, as a result, serve different purposes. What gets used and for what purpose?

Oil

Owing to the presence of natural resins, a thin yellow film covers the product. used for interior house structures and flooring.

Alkyd

Frequently mistaken for oil. The only thing that unites them is the use of resins; however, alkyd contains synthetic ingredients.

Alciden varnish

The tree is flawlessly polished because of alkyd varnishes, but because of the alcohol base, this type of composition is not moisture resistant.

Alquid-carbamide

Varnish that needs a unique, acidic hardener.

Wood varnish

• After drying, leaves a protective layer on the surface.
• But since before application it is mixed with hardener, after drying it becomes wear -resistant.

This is why it is applied to materials that are used continuously. Owing to its strength following drying, it can be utilized off-site.

Nitro -cellulose (etherocellulose)

The varnish’s intricate composition yields a completely transparent finish with exceptional protective qualities. utilized for items and surfaces that are continuously in the space.

The varnish is craquelure

Polyesh

The name itself suggests a composition with multiple components. A thick layer of solid surface material forms after drying. Since it is challenging to penetrate water through such barriers, it is most noticeable outside of buildings.

Parquet varnish

Polyurethane

Regarding him, it can be stated that he never tires or grinds. For this reason, it is applied to surfaces in areas with excellent cross-country capabilities.

Polyurethane with the water base

The youngest. To put it simply, polyurethane is environmentally friendly and offers excellent protection against erasure. The product’s service life will be extended if the surface is strengthened prior to varnishing.

Recommendations on the use of varnish

In order to achieve a longer-lasting effect with varnish, there are a few subtleties to consider:

1. Pull the surface of the wood.
2. All old compositions must be cleaned from the surface.
3. There should not be any dust or garbage on the surface.
4. Bright the material.
5. Only after careful preparation can it be applied.

However, the varnish also has unique qualities of its own:

1. When applying with a brush, even a hard -to -reach surface is covered, but there may remain stains if you do not choose a brush with a pile dissolved at the end.
2. The processing of smooth elements can be carried out with a roller, but the villi should not exceed 5 millimeters long.
3. When using a spray gun, the product is covered exactly with a minimum expenditure of the product, but in the presence of small parts, droplets can form.

How to choose a tree for wood

How can one avoid becoming lost in a vast array of options? Experts recommend considering the following key factors:

• Choose a well -known manufacturer for a long time working in this market, about which you can read reviews.
• Be sure to consider what exactly you need varnish for. Such information is indicated on the package.
• There are funds for work in the premises, but there is for work outside the same. This also must be taken into account when purchasing varnish, t.To. The classification takes into account resistance and harm to humans.
• Additionally, take into account what is a solvent for varnish. This will help to eliminate the shortcomings or dilute the thickening varnish.
• A very important indicator – drying out. It depends on it after what time it will be possible to use the product or room.
• Depending on the location of the covered surfaces, it is also necessary to take into account the degree of thermal protection.
• Most often, substances protecting the surface from ultraviolet radiation are added to the varnishes for external work. Consider this indicator if you do not want the surface to quickly darken or crack.
• When choosing varnish, take into account that consisting of 1 component is already ready for use, but it is more expensive, and consisting of 2 components requires preliminary mixing with a hardener, but it is cheaper.
• There are varnishes of various colors. If you want to preserve the visual structure of the tree, choose a coating that has no color pigment.
• It is necessary to take into account the indicators of the minimum and maximum consumption. Without them it is impossible to calculate how much varnish is required.
• Think in advance which finish do you want to get.
• For the calculation, take into account that weight exceeds the amount of about half.
• It happens that the manufacturer clearly indicates the methods of applying its products. Check out such information before buying to purchase the missing tool if necessary.
• The content of hazardous substances must be taken into account if work is carried out in houses with permanent people. If nobody will live in the house complete to completely dry in the house, then this parameter can not be taken into account.
• There are many varnishes that do not require thoroughly preparing surfaces, but there are those that will not stay on a tree without a primer. Be sure to study the information about the preparatory work on the packaging.

These selection criteria are not clever. Naturally, these are not universal, and each person chooses what matters more to them. However, the outcome will be better if you approach the varnish selection with more care.

Classification at the place of application

There are two categories that can be identified at the application location:

However, you can split it for a more specific objective:

1. Parquet.
2. Furniture.
3. For street work.

Furniture varnish

What is the difference between varnishes?

The way that wood is protected from the effects of nature is one of the biggest distinctions. The tree’s size fluctuates constantly because of the humidity level. Because of the elastic film, the varnish for work done outside the premises prevents wood from deteriorating due to frequent size changes.

It is useless to use lacques on the street because they lack this kind of protection when they are used indoors.

Tricks of varnish

There are subtleties when working with varnish, despite its seeming simplicity.

Dust mask

Calculation of consumption

Prior to anything else, the amount of paintwork must be decided. Several factors need to be considered in order to accurately calculate the desired volume:

• The porosity of the wooden surface. The more and deeper the pores, the more varnish is needed.
• The density of the varnish itself. The thicker it is, the greater the volume will need. For the first layer, the composition is allowed to dilute the appropriate dilute.
• The more smooth grinding of the surface, the less varnish will be required.
• The volume also depends on the application method. When using a spray gun, the composition of the composition is less.

Up to roughly 10 square meters, one layer can be applied with one liter of material. The approximate area increases to 20 square meters when planning a two-layer coating.

Removing old varnish

It’s not the first time opening wood with varnish, so it’s important to discard the old remedy. It is vital to consider the following information in order to do this:

• Why covered wood was used;
• Which layer was applied;
• What kind of paint and varnish was used.

Chemical solvents are the most widely used method for removing old varnish. They are chosen universally or according to the kind of varnish.

Utilizing these funds doesn’t require a complicated process; all that needs to be done is follow the guidelines and take safety precautions. A rubberized spatula is used to remove the solvent after it has been applied evenly across the surface.

It is possible to remove the varnish mechanically if you prefer not to come into contact with chemicals. You can use a surface grinding machine or a specialized scraper to accomplish this.

Nuances when applying varnish

It is recommended to cover the wood in two layers to extend its lifespan. The second is already thicker, and the first dries in a matter of hours. For a very long time, the second layer may completely dry out.

Wood varnish

• Varnishing is similar to painting. Excesses are removed from the brush, and the composition is carried by the product. When forming bubbles in the process, they are removed immediately with a brush.
• As already described earlier, the speed of complete drying of the paintwork depends on its properties and the number of layers applied.
• If a painted product is covered with varnish, it is better to choose acrylic compositions. So they will strengthen each other. But it should be remembered that acrylic paint itself gives excellent protection. In this regard, applying varnish after paint can only be an empty waste of cash.

Getting rid of the smell of varnish

Some people are extremely sensitive to odors, particularly following repairs. It is preferable to get rid of the lingering paint and varnish smell so that everyone who occupies the house feels comfortable.

There are various methods for getting rid of:

• Regular wiping of a varnished surface with a vinegar solution (two tablespoons of vinegar per 7 liters of water);
• Before use in a tank with varnish, you can add a couple of drops of mint or vanilla essence;
• Creation in a decreased humidity;
• Regular and prolonged ventilation of the room with lacquered objects;
• Air cleaning with a special device.

Vanilla Essence

Why bubbles appear

This varnish behavior can be attributed to a number of factors:

• High moisture content of wood;
• A lot of not distributed when applying varnish;
• The inappropriate application method has been used;
• Poor compatibility of varnish with previously applied compounds;
• Poorly polished surface;
• If a two -component composition is used, then a poorly mixed mixture can cause bubbles;
• Non -leafy previous layer;
• There was dust or dirt on the surface.

There are various causes. Even a seemingly insignificant detail at work can derail the outcome.
