How and how to remove old paint from a wooden surface?

How to remove paint from a wooden surface? In the process of repair in a house or apartment, there is almost always a need to update and give a noble appearance to important components of the interior: window frames, entrance and interior doors.

Of course, it is much easier to install popular plastic counterparts and then admire the elegant look, which immediately "puts on" the room.

But it is much better to live surrounded by natural materials, which are only required to be renewed, restored and modernized by ordinary painting.

Is it necessary to remove the old paint?

According to the state of the old layer of paint should be determined: a fresh paint applied over it, or still make a preliminary cleaning from the old decor. The main criteria for making the right decision will be:

• The prescription for the previous painting, which, under the influence of time, can begin to exfoliate independently. If a new layer is applied to the peeling surface from above, the painted area will have a hilly and sloppy appearance.
• Thickness. A single layer of the previous coating can not be removed. The coloring material is superimposed on it much better and lasts longer. In addition, wood is not threatened with another impact. In case of multilayers, the paint layer is characterized by low strength and density and is destroyed with little mechanical impact.
• Colour. When applying a thin and loose layer of paint, the color of the old surface will appear, or new and old paints will blend. For example, a red color applied to the blue will result in a purple hue.
• The texture that may not coincide with the qualitative characteristics of the previous layer. So, how to remove old paint from a wooden surface?

Preparatory stage

In the absence of cracks, blisters and damages on the working surface, it will suffice to pre-paint the sandpaper. Remove a thick layer of paint or accumulated for many years, a large number of layers. On concrete and metal products characterized by a hard surface, getting rid of the old coating is much easier than on a tree - a soft material easily damaging.

Before removing the previous coating, first of all, you should inspect the condition, structure and quality of the product planned for painting and make sure that it can be used again.

We get rid of the old paint: effective methods

Let's figure out how to remove old paint from a wooden surface at home.

Removal of the old layer is a rather laborious process, requiring a lot of time and effort. Therefore, sometimes the appeal to professional masters is better than independent actions. There are a few sparing ways to accurately and safely remove the old paint layer, causing a minimal amount of wood damage:

• Chemical, involving the use of various reagents;
• Thermal, using high temperatures;
• Mechanical, in which the impact on the working surface is made with the help of auxiliary tools.

When choosing methods for removing old coatings, personal safety and personal protective equipment must be used.

Chemical method

How and how to remove the old paint from the wood surface the fastest, not dusty and does not require special efforts by chemical means?

Disposal from the previously applied layer is made by treating the product with special chemical solutions that impregnate the paint and foaming it from the inside. The application of such effective substances is required using a spray gun, a small pile roller or a brush. Then it takes 20-25 minutes to wait, to allow the substance to fully manifest its destructive abilities. As a result, the old layer will be removed without much difficulty.

To help you can take mechanical tools (for example, spatula).

It is problematic to use chemicals when removing the old paint on the ceiling, but manufacturers have found a way out and are releasing similar products in the form of jelly. Even if they are applied with a brush, they do not drain down.

By financial measures, the chemical method is very expensive: a unit of a high quality drug in money equivalent is equal to the price of the paint itself. In addition, the material used requires special disposal. The disadvantage is the pungent smell of drugs, as well as the release of toxic fumes. Therefore, in order to avoid burns and poisoning, work should be carried out in a respirator, protective gloves and glasses. Before starting the process, the room should be well ventilated. And how is it easier to remove old paint from a wooden surface?

We use hot air

The invention of a construction hair dryer caused the appearance of thermal removal of the old paint layer. Are you interested in how to remove old paint from a wooden surface with a hair dryer? The device is able to heat the surface to 600 ^о С. Under the influence of high temperatures, the paint foams and is easily removed with a chisel, scraper or spatula. Building hair dryer is not recommended for use in rooms with plastic windows and open wiring, since at high temperatures they can easily ignite. In the absence of a construction hair dryer, you can use food foil: apply it to the surface, warm with an iron (old, which is not a pity). The "ironing" method heats the surface, so you can safely get rid of the old paint layer.

It is not recommended to work on the work area of the product with open fire (gas burners) to remove old paint, because of the risk of possible fire. In addition, it can cause drying and breaking the structure of wood, which negatively affects the strength of the product and the timing of its operation. Separate wood species can heat up flammable resins during heat treatment, which also form a specific film on the product. The latter significantly reduces the adhesion (adhesion of surfaces), and may even completely prevent the application of a new layer of colorant on the product .

Effective mechanical method

Let's explore more ways of how to remove old paint from a wooden surface at home. Sufficiently effective is the mechanical method, which is the scraping of the old paint with the help of improvised tools: a knife, a spatula or a Bulgarian. On a small and uneven surface, it can be scraped with sharp attachments.

How to remove old paint from the wooden surface of large areas? In this case, the use of power tools that significantly speeds up the workflow is effective: grinders or drills with special circles on which sandpaper or any other material with an abrasive is put on. With a single layer of old paint, an abrasive disc can easily cope if there are several layers - as an attachment, the use of brushes is effective.

Features of work with a tree

When working with an electric drill or a Bulgarian, the paint is removed dry, so the working process takes place in a large dust cloud. Therefore, you should always use a respirator, goggles and gloves. Before removing the old paint from the wood by a mechanical method, attention should be paid to the tree species, since improperly selected abrasives can significantly damage its surface. Coarse-grained paper can leave significant scratches on the surface, especially if the work is done with a certain amount of effort. Therefore, it is better to change the abrasive material to a fine-grained analog and not to exert much effort when in contact with a wooden surface. The scratches that appear as a result of the mechanical impact should be ground and ground.

Which way to choose?

How to decide how to remove old paint from a wooden surface? If the area to be treated is large and level, a mechanical method using various power tools should be used. If you can not connect to the network, you can use chemicals, after which you must remove the old layer with ordinary scrapers.

Purify with caustic soda

How to remove old paint from a wooden floor surface? If you are unwilling or unable to use these methods, you can try using caustic soda solution. This method is optimal for any surfaces, but requires great care.

Components for the workflow:

• old clothes;
• latex gloves;
• brush;
• putty knife;
• Cropped plastic bottle;
• mortar;
• Caustic soda.

The "softener" of the paint is prepared from a portion of soda ash diluted in three parts of the lime mortar. The resulting composition is applied by brush on the work surface for 10-20 minutes, after which the layer of the old layer of paint begins to bubble. To accelerate the process surface with a softened paint is recommended to scrape with a stiff brush or knife. Then you need to carefully remove the paint using a spatula, wipe the surface with degreasing solution, or rinse thoroughly with water.

How to remove old paint from a wooden surface? Means that have proven themselves in this matter are caustic soda and oatmeal, from which it is easy to prepare an effective pasta. It is only necessary to dilute these components with water, after which it is applied to the working surface.

After a while, remove with paint and rinse with water. In case of skin contact, this medication should be removed immediately.

Acetone to the rescue

Do you know how to remove old paint from a wooden surface with acetone? This tool, perhaps, like gasoline, is the most popular among people who have faced the problem of removing the old paint layer.

Acetone, which is a solvent, destroys the molecular structure of matter, and it gradually begins to disappear from the surface. Remove this way, you can paint on a small surface. The treatment should be carried out very carefully due to the toxicity and flammability of these liquids. Before starting work, the room should be well ventilated.

Also, for cleaning wooden surfaces, some craftsmen use a solution of household soap and turpentine.

New old things

It is quite natural that updating surfaces is a laborious process and sometimes quite protracted. Perhaps, it is sometimes even easier to buy a new wardrobe, put a new door and lay a floor covering. But still finding among your favorite things that surround you for years is much more familiar and comfortable. Maybe you should try to breathe new life into them.
