Removing varnish from parquet. An example of do-it-yourself parquet restoration. Machine scraping method

Of course, parquet is the most wear-resistant floor surface finish, especially when a layer of high-quality varnish is applied on top. However, no coverage is immune to the process of obsolescence. Experts do not indicate a specific period when the old varnish needs to be replaced with a new one; everything here is individual.

But, of course, there are factors that influence the duration of this period, namely:

• it is necessary to take into account in which room it was produced and for what purposes it is used;
• whether all recommendations specified in the instructions for the materials were followed during the process of laying parquet and coating it with a varnish substance;
• is it carried out proper care behind the surface (using gentle detergents, a cloth or a household sponge);
• whether the type of varnish coating was initially chosen correctly.

In most cases, varnish replacement is necessary after using parquet for 10–15 years. If the surface is severely damaged by heaters or animals in the area, you will need to find out how to remove the varnish from the parquet and apply a new one much earlier.

Where a large number of people pass daily (most often this is government agencies), are subject to annual renewal of the varnish component on the parquet.

Choosing varnish for parquet

Criterias of choice

When initially deciding on a varnish for a parquet surface, you need to understand what kind of load it must withstand, so that you don’t have to do it too soon. Today, the construction market is overflowing with various varnish substances that differ from each other in technological parameters, chemical components, and application options.

Basically, consumers pay attention to the following main varnish-containing substances:

• water-free polyurethane;
• water soluble;
• acid-curing;
• primers;
• manufactured on oil resins.

Some of them are glossy and reflect approximately 70–100% of light, others are characterized by semi-gloss (30–70% of light). Semi-matte and matte are dull and discreet, hiding blemishes and surface defects. What does shine depend on? On the degree of presence of filler in the material, which scatters light.

As for abrasion resistance, the highest quality in this regard are polyurethane and waterless varnishes. Acrylic, on the contrary, is not durable, but at the same time it withstands the influence of chemical compounds from the outside.

Polyurethane varnishes

Plastic varnishes fit perfectly on the surface and are applied in a thin layer.

Be careful not to allow any liquid to come into contact with the material during drying, which will ruin the finish and foam the newly applied material. Interestingly, this substance is also used as a “glue” that connects parquet components.

Water soluble

Thanks to water, they are non-flammable and have no unpleasant pungent odor.

During application, experts advise maintaining a temperature of 18–20 degrees with a humidity of 50% or more in the room. It is optimal to coat parquet with varnish using a roller.

Primers

They protect parquet flooring edges from curvature and deformation. It is important to apply the material by moving the brush along the grain of the wood. Drying times vary: from 15 minutes to 3 hours.

Varnishes based on artificial oil resins

The resin contained in the substance is perfectly absorbed by wood. This type of material requires oxygen to dry.

No need before applying varnish. Don’t be surprised if, after hardening, the varnish turns the parquet into a completely different color; it also dries better with a good ventilation system and an average air temperature; it does not tolerate sudden changes and fluctuations in temperature conditions.

When working with this type of varnish substances, it should be borne in mind that they are toxic, which means you should always remember safety measures - wear a respirator and use gloves.

Acid-curing substances

Before applying such varnish, it is necessary to dilute it with acid and hardener. It is this material that provides the hardest and reliable coverage parquet The presence of alcohol in the composition forces craftsmen to ventilate the room well while applying the material.

It is ideal to cover the varnish substance in three layers; it dries for at least a day, but will also last quite a long time.

Required Tools

Finally, you have decided which varnish is best to cover the parquet after removing the old layer of material. In order to clean parquet from varnish, you must have the following list of products and tools:

1. putty mixture;
2. grinding machine;
3. vacuum cleaner.

Step by step guide

When repairing parquet, it is important to replace the varnish in a timely manner, preventing it from completely abrading and trampled marks appearing on the surface.

Before removing the varnish from the parquet, you need to sand the surface. If the damage is deep and clearly visible, in addition to the varnish substance, an additional 0.5 mm of wood is removed, but no more.

Borrow a grinding machine from your friends that will handle this procedure as gently and accurately as possible. In this case, the room should be well ventilated and ventilated - there will be a lot of dust. You can turn on the vacuum cleaner in advance, which will also remove a certain part of dust particles from the air. Remember to protect your lungs and eyes with protective equipment.

Before starting the sanding procedure, thoroughly cover all the cracks with putty, wipe the floor with a slightly damp cloth, thus clearing it of dirt. Now start sanding. This work is painstaking and cannot be rushed. A small household sander may require several days of sanding on the floor.

Experts point out that if the parquet is too damaged, it must be sanded, which is carried out using a drum machine. In everyday life, this procedure looks somewhat different. First, an abrasive is taken to remove the paint, then all visible gaps are covered with putty mixture. After that, a medium-hard abrasive comes into play, which negates the remaining rough scratches. The final stage is cleaning the parquet with a fine abrasive. This floor is covered with at least 2 layers of varnish.

Conclusion

When starting to work on your own, follow the technology, repeat step by step what is written in the instructions, and you will succeed. Pay attention to what varnish substance should be applied subsequently - the life of the parquet surface depends on this.

The parquet surface can be protected different ways, preference is often given to parquet varnish. But no matter how durable and high-quality the varnish for parquet is, it still wears off over time, so you have to carry out work to restore the varnish coating on the parquet.

Parquet cleaning and sanding

The essence of updating the varnish coating for parquet is to carry out several stages. First you need to remove the old varnish coating from the floor surface. The parquet needs to be cleaned and sanded well. The optimal device for cleaning old parquet flooring is a sanding machine. There are parquets different types, so the grinding machines will be different.

Before sanding, it is necessary to check the moisture level of the parquet. The night before, you need to attach a piece of plastic bag to the surface of the parquet using tape. In the morning you need to look at inner side cellophane - if it is damp, with droplets of condensation, then the humidity of the parquet is high. Therefore, the parquet must be dried before sanding. In the case when the cellophane does not contain condensation, the parquet can be sanded immediately, without additional drying.

Sanding parquet requires some attention. If the varnish coating is slightly damaged, you can clean it with a coarse sandpaper damaged areas, and then cover these areas with varnish. With this method of updating, the varnished parquet flooring will be uneven, and the spots of the new coating will stand out unsightly. Therefore, it would be better to renew the entire varnish coating on the parquet.

You can also remove the old varnish coating using milling machines, which successfully replace sanding machines. Distinctive feature Milling installations for cleaning parquet from varnish are considered to have sharp knives. The varnish coating is peeled off along with the top layer of wood. After use milling installation, the floor still needs to be sanded before applying the varnish. Before sanding, you must remove all baseboards around the perimeter of the room. This will completely clean the parquet from varnish.

Puttying

After grinding, it is necessary to carry out the putty procedure - all the resulting chips and scratches are repaired with putty compounds, then they are cleaned using emery cloth. The putty should match the color of the parquet wood as closely as possible, and allow five to six hours to dry. After this, the floor can be re-varnished.

Putty is selected specifically for wood; it is usually made on an acrylic base; sometimes for the production of wood putties they are made using nitro solvents. The putty must be applied in a very thin layer. If necessary, a second layer can be applied, but the first putty layer must dry completely. Water-based putty cannot be used on some valuable tree species– oak, cedar, chestnut.

When treated with water-based putties, such wood appears with whitish and blue spots. Instead of putties, you can use – Alternative option for parquet. The cost of such wax is much more expensive than putty, but it does not shrink at all and has a translucent color. When using wax to level the floor, do not use polyurethane varnish– with this combination, peeling of the varnish coating very often occurs after a short time.

Polishing and varnishing

After polishing, we begin to apply a new varnish coating. Parquet varnish is selected depending on the type of parquet base; it is advisable to consult with specialists on this matter.

Parquet varnish must be wear-resistant, usually water-based or acrylic-based varnish. You can also use artificially produced varnishes for parquet – alkyd or polyurethane products.

Let's apply a special varnish remover to our surface.

Wooden surfaces (parquet, furniture, panels, etc.) are often varnished to preserve the natural grain of the wood.

The question arises: how to remove varnish from wooden surface to prepare the site for the new coating.

What are the methods for removing varnish?

Mechanical method. Using sandpaper, a special attachment on a drill, or a sanding machine, remove the varnish layer from the wooden surface. In this case, you may suffer upper layer tree. This method is generally not suitable for restoration work.

Thermal method. By firing blowtorch or use a hairdryer on a painted wooden surface to achieve peeling of the varnish, and then remove it with mechanical devices (trowel, chisel, sandpaper). A tree can change its structure. The method is fire hazardous and toxic.

Chemical method. How to remove varnish from a wooden surface is decided by experts who determine several important factors, choosing a remover:

• what varnish is used to paint the surface?
• thickness of varnish layers;
• what kind of wooden product is varnished;
• degree of adhesion of varnish to wood;
• type of subsequent processing (varnishing, painting, etc.).

The effectiveness of removing varnish and preserving the top layer of a wooden surface, especially on furniture and parquet, depend on these components.

Chemicals for removing varnish

1. Cleaning and detergents, which can be used to remove a thin layer of varnish on a polished wooden surface. You just have to rub it well with a stiff brush to peel off the varnish.
2. Organic solvents (white spirit, solvent, etc.) are used for strong adhesion of the varnish to the surface. To clean wood, the solvent is sprayed or applied with a sponge to varnished surface, left to soak, and then mechanical devices are used, depending on the thickness of the varnish layers. The thinnest layers are removed with simple sandpaper, and several layers have to be removed with a spatula.
3. Special chemical removers, gel- or powder-like, in a ready-made solution, can be used for different types of varnish.

How do special washes work?

• Removes the thickest layers of varnish.
• Cleans the pores of untreated wood into which the varnish has been absorbed.
• The highest degree of adhesion will be destroyed if a thick layer of gel-like mass or paste is applied to a wooden surface with a spatula or brush. The expiration time is indicated in the instructions, but better remedy leave for full chemical reaction for 2-4 hours, observing changes on the surface. To enhance the effect wooden crafts cover with film (the so-called “compress”).
• The surface cleared of varnish is washed off with water and wiped dry with a rag. After complete drying, the wooden surface is ready for new painting.

For a room of about 10 m² it will take 2 days.

First, you need to insert a sanding disc into the machine. It is also necessary to adjust the desired rotation speed of the drum, which should correspond to the hardness of the parquet. Each strip of coverage is passed twice, both in one direction and in the other.
For high-quality grinding, grinder pass first diagonally, and then in the direction of laying the plates.

As with any grinding, you need to monitor the abrasive disc and update it periodically. Use coarse first abrasive discs which to obtain the most smooth surface as work progresses, they are replaced with fine-grained elements. The distances between the parquet boards must also be even.
