Bleaching of wood: technology and work order

If the wood has lost the appeal of appearance, then it can give a second life, bleaching the surface. To do this, there are many options, among which, for example, chlorine. These substances are available and inexpensive, so they can be used by you at home.

Bleaching with chlorine: preparation of tools and materials

Bleaching of wood can be carried out with the help of chlorine, while you should prepare:

• Crystalline soda;
• sodium hydroxide;
• Chlorine lime;
• Water;
• Perhydrol.

By the way about the last point, it is worth noting that for the work will need 30% hydrogen peroxide solution. It should be remembered that such work is necessarily carried out in gloves.

Carrying out bleaching

Bleaching of wood should be conducted by a certain technology. To do this, prepare a special solution of eight parts of bleach, which must be mixed with one share of salt, adding 35 parts of water. The resulting mixture is stirred and allowed to infuse the solution, only after it is possible to start processing the wood.

The second option is to prepare a solution of caustic soda, for which 48 grams of chemical substance and water are mixed in a volume of 100 grams. A solution of caustic soda should be applied to the surface of the tree, which is then dried. Sometimes domestic craftsmen treat wood with perhydrol, it is dried at the final stage, and if bleaching is insufficient, the procedure can be repeated. In order to neutralize this area, it should be washed with a 4% solution of acetic acid, and then dried well.

Bleaching of wood is sometimes carried out with the help of hydrogen peroxide, as well as ammonia. "Hydroperitum" in tablets is diluted with water: 10 tablets per glass of water (200 ml). While 5 percent ammonia is added in the amount of 25 milliliters (its smell should be well felt). In this solution, you need to soak the wood and leave it for a few days, while you should expect the effect that the surface will become completely white.

Recommendations of professionals

The use of peroxide, although effective, but not suitable for all types of wood. For example, an oak can not change color after processing, whereas for bleaching a nut, birch and beech, this method is ideal. It is important to use the correct concentration of the solution, which should not be less than 30%. Before applying, the surface should be moistened with warm water and covered with 5% ammonia. After the bleaching is completed, the surface is cleaned with a mixture of bleach and soda ash. For 15 grams of lime should be added 3 grams of soda and 100 grams of water.

Use of oxalic acid

Bleaching of wood by one's own hands can be conducted with the use of oxalic acid, but they carry out such work with great care. This is due to the fact that the desired effect can be achieved only with the correct percentage of components. To do this, prepare a 10% solution of oxalic acid and sodium hydrogen sulfate in a concentration of 20%. On the surface, sodium hydrogen sulphate is applied in the first stage, and after - a solution of oxalic acid. After 5 minutes, the formulations are washed off with water.

Nuances of works

Bleaching of wood can be carried out by different technologies, however at the final stage all means should be washed off from the surface. If you decide to use acid bleach, then wash it with an aqueous solution. Bleaching substances can not be combined. Glued products are not recommended to be subjected to such treatment, since they can disperse. If you want to bleach the pine wood in a short time, the surface can be treated with a solution of sulfuric acid (taken in the amount of 20 grams), sodium peroxide (in a volume of 25 grams) and oxalic acid (15 grams). The liquid is added to the volume of one hundred grams.

Use of the "Acrylite 153"

Whitening of wood with whiteness is considered very effective, but alternative solutions, for example "Acrylite 153", can also be used. This product is specially designed for darkened wood and is able to remove microorganisms without hindering the breathing of the material, and without destroying its structure.

The substance does not affect the strength, adhesion and porosity of the surface and does not change the smell of wood. What can not be said, when the whitening of wood with whiteness is made, the proportions do not need to be observed at the same time. To perform the work it will be necessary to moisten the sponge in the solution and apply the composition to the surface.

But as for "Acrylate 153", it must be diluted with water before use, using a ratio of one to one. If the wood is damaged sufficiently strongly, then it is not necessary to dilute the product, it is necessary to produce the composition on the surface with a roller. If the whitening seems to you not too intense, then repeat the procedure in five hours. It is noteworthy that this agent can be used even for bleaching pine.

Additional solution

On sale today you can find a means of "Valcor", the cost of which is 1800 rubles. His tinting is done in five minutes. You can use an alkyd-oil stain that has almost no odor, but helps to blend the array to an almost white state. Among the ingredients of the mixture are antiseptic additives, so the stain after finishing the wood can not be covered. As practice shows, this product perfectly whitens the birch, and even under the water-based lacquer the surface remains noticeably lighter.

Sometimes experts use paint based on oils and wax Decorwachs Deckend. It has a transparent structure, and after coating the wood, only the texture remains visible. Gradually, the veins of the material appear on the surface. On sale it is possible to meet oil with firm wax which at drawing allows to generate a pinkish shade of an oak. If we are talking about pine, it will simply whiten, leaving an invoice. The coating is applied in two layers, and then covered with a colorless oil with a hard wax. As a result, you will be able to get a silky surface. After coating, the wood not only brightens, but becomes harder, which is possible thanks to carnauba wax.

Conclusion

Bleaching wood with chlorine, like each of the above options, is an effective way. What method to use is up to you, it all depends on the budget and your own preferences.
