How to remove old varnish from furniture with solvent
To remove varnish from furniture at home, you can use a special varnish remover. Such products have high penetrating power and make it easy and quick to clean the surface.
But furniture can be treated with different varnishes on different bases, so it is necessary to choose a solvent that will not harm the furniture and will allow you to achieve results. But you can only remove varnish using solvents from wooden surfaces.
Before removing old varnish from furniture , you need to prepare the wooden surface of the furniture. First of all, it must be cleaned of contaminants. Over the years, a lot of grease and dirt has accumulated on its surface, which must be removed with ordinary soapy water.
Try to clean all the recesses, nooks and panels. Proceed carefully, the wood should not get too wet, and the soap composition should only clean the contaminated surface and not remove the coating from it.
It is better to treat panels and shaped parts of furniture with special solvents to remove old varnish.
There is no point in talking about how to remove varnish from old chipboard furniture, because... this cannot be done. Together with the varnish layer, the decorative layer that replicates this or that texture will be removed or significantly damaged.
Required Tools
To completely remove old varnish from wood, you will need the following set of tools:
- cellophane film;
- construction hair dryer (a regular hair dryer is not effective for drying hair);
- wire brush with hard bristles;
- brush;
- kitchen sponge;
- mask, respirator for respiratory protection;
- chemical mixture for washing off the composition;
- eye protection glasses;
- thick gloves;
- grinding and sandpaper.
Remove varnish from furniture by sanding
Using sanding, you can not only remove varnish, but also level the surface of wooden furniture. Sanding is done with sandpaper (abrasive) paper manually or using a sanding machine.
To make hand sanding easier, use a simple wooden block and wrap a piece of sandpaper around it.
To remove varnish from furniture , start sanding the surface with medium-grain paper, gradually moving to fine-grain paper.
A special sanding machine of small size and power will greatly simplify the removal of varnish. For such a machine, only fabric-based sandpaper is suitable.
After each sanding step, remove dust from the surface of the object with a slightly damp cotton cloth.
Before removing varnish from furniture , buy a special device with a grip for sandpaper at a hardware store. This will allow you to distribute the sanding pressure evenly.
To sand rounded and convex surfaces, move the sandpaper strip up and down at right angles.
Methods for carrying out restoration measures
Analysis of the degree of wear of lacquered furniture
First, you need to analyze the current conditions of the furniture to be repaired. A good reason to start the restoration process will be deterioration in the appearance of the headset, including darkening in the thread area. In addition, a common reason for restoration is small cracks on the surface.
In cases where such defects are not very pronounced, they may not harm the appearance, but, on the contrary, add solidity to it. In the case of severe defects, there is a need for restoration measures, which are organized by a professional from a specialized workshop, or they can be carried out independently at home, while preserving the antique qualities of the furniture.
If something goes wrong, you can cover the product with paint at any time, although then the unique pattern inherent in the wood will be hidden by the paint and the furniture will lose its presentable appearance.
How and how to remove paint from a wooden surface
It is very difficult to completely remove old paint from the surface of furniture, but we will try. For this, special chemical solvents are most often used, which can be purchased at construction or specialized stores, as well as construction hair dryers.
Gently wash the surface of the product with a dishwashing sponge. Instead of a sponge, you can use foam rubber or cotton cloth. Remove soap solution and dirt from the surface of the furniture by wiping it with a soft cotton cloth, first slightly damp, then dry.
First, let's look at how to remove paint from furniture using a solvent and a metal spatula:
- Apply solvent with a synthetic flute brush. Sometimes it is necessary to apply several layers of solvent to remove a thick layer of paint. Follow the time recommended by the manufacturer.
- When the paint softens and begins to peel off the surface of the wood, scrape it off with a metal putty knife.
- Depending on the composition of the old paint and the number of layers, it may be necessary to reapply the solvent to achieve greater softening and swelling of the paint.
Acrylic paints do not adhere to surfaces that have been pre-treated with oil. To remove oil coating, soak steel wool in mineral spirits and rub the surface in a circular motion.
Chemical solvents for removing old paint and varnish are very toxic and require working outdoors or in a well-ventilated area. Then how and how to remove paint from a wooden surface if you do not have the opportunity to take the product to an open place? In this case, use a hair dryer. Working with it is more difficult, but safer for health. Direct a stream of hot air at the old paint and wait for it to swell, then remove the coating with a spatula or scraper.
Store products
Specialized stores have a wide range of products that allow you to remove the paint layer. Such compositions can be in the form of powders and pastes. These types are considered the most effective; they are diluted with water to a paste-like state and applied to the wood with a brush. Pastes and powders are the most effective because they remove up to 10 layers of varnish.
Gels and liquids supplied ready-to-use are less effective. They are also applied with a brush, but they can remove up to 3 layers of varnish. Sprays are considered the most convenient for use, however, their effectiveness is the least in comparison with analogues. After any of the above products are applied to the varnish coating, it must be covered with cellophane film. It is removed when the surface darkens and the varnish mixture becomes viscous, then the paint and varnish material is removed from the furniture using a spatula.
Restore furniture surface: a quick way
Having completed the job of removing old paint from furniture or doors, we often, unfortunately, discover that there is nothing good underneath - just putty and potholed wood. And now there is only more work to do with such a surface before applying new paint!
But you can use a quick way to restore the paint coating. To do this, follow the following instructions:
- To restore the surface of furniture, remove paint only in those places where it has peeled off using a metal spatula.
- Sand the surface of the product covered with old paint using a sanding machine, using first medium-grit sandpaper, then fine-grit sandpaper. Don't try to remove the paint, just smooth it out. If necessary, sand the entire surface of the product using the old paint, leveling and removing defects (for example, smudges and drops of old paint).
- Fill all cleaned areas using wood putty. The drying time for the putty is recommended by the manufacturer.
- After the putty has dried, sand the surface again - manually or using a sander.
- After this, wipe the product from dust and repaint the entire surface in two or three layers.
The surface prepared in this way can be repainted in any color, using the old coating as a primer.
When sanding, be sure to wear a mask to protect you from dust. Only work with chemical solvents outdoors or in a well-ventilated area and be sure to wear rubber gloves. Follow manufacturers' instructions regarding use, storage and disposal of solvent.
If your home is not the Hermitage, and the furniture is just an old shelf or bedside table, use this easy way to restore the paint finish.
Thermal method
When heated, the structure of the varnish coating changes, the varnish becomes more liquid, the degree of its adhesion to the wood decreases significantly, which means it will be much easier to remove. However, here you need to follow several rules. First of all, it is important to take care of protection, that is, use special glasses to protect your eyes during work, as well as thick gloves. Before starting the process, you need to open the windows so that the room is well ventilated (this is important, because toxic chemical elements can be released during the melting of the varnish, which increases the risk of developing poisoning and allergies). In addition, there are coatings with a special composition that, when heated, does not melt, but chars. In this case, it is better to choose another method of removing varnish.
Mechanical cleaning
Method 1
Using coarse sandpaper or a sander:
- Wear self-defense equipment.
- Thread sandpaper into the machine (paper grit from 80 to 120).
- Treat the wooden surface.
- Use new paper, grain size 180.
- Re-treat the surface until the varnish is completely removed.
Method 2
If the old paintwork has already begun to peel off and fall off in pieces, then:
- Clean the surface with a wire brush or coarse sandpaper using a circular motion.
- In places where the varnish remains, remove it with a screwdriver or spatula.
Important! Mechanical cleaning methods are crude, so their use is only possible if the furniture is covered with enamel or paint.
We remove everything that interferes
In order to paint any object with high quality, you need to remove, if possible, everything that cannot be painted, and therefore gets in the way. Of course, you shouldn’t completely disassemble the furniture - what if you can’t put it back together? But it is necessary to remove the doors, remove the drawers and shelves, remove the glass and unscrew the handles and hinges.
Remove everything that interferes with painting. Carefully cover anything that interferes but cannot be easily removed with masking tape. If the part is curved and convex, you need to glue it in several layers, using small pieces of tape, as when working with papier-mâché. For more complete coverage and minimal joints, stick the strip with a small margin, so that you can then trim off the excess.
