What is the difference between waterproof plywood and ordinary

Veneer, a type of plywood sheet resistant to moisture, is derived from coniferous or deciduous woods. Adhesives are used to join the layers, and a specific technique is followed in processing the surface. Similar processing makes plywood water resistant.

There are several types of plywood sheets that can be identified:

  • With labeling "FV". They are safe, but cannot withstand humidity;
  • FC is a more resistant type to water, but is still used only for dry rooms. Not suitable for products operated on the street;
  • FSF resistant to moisture type of plywood, phenolformeldehyde glue is used for its production. However, a toxic, good option only for products used on the street;
  • FBS is a completely moisture resistant option, but the cost is high.

How to make a plywood with a moisture -resistant with your own hands

It is true that the method you use to soak plywood to increase its moisture resistance matters. Different compounds have different qualities and can endow the material with additional protective qualities. Therefore, you can obtain full color change in the material, only tint change in the material, or additional fire-retardant properties.

Painting nitroemal

Painting produces an excellent outcome and can act as a barrier against water’s direct effect on the base. The following is how the procedure is executed:

  • The material is polished from all sides, grinding with large and medium sandpaper is used;
  • Olifa is applied, it is important to qualitatively process the ends;
  • Liquid type of paint is applied in several layers on the base, the last, usually the third layer, is made thinner than the previous ones;
  • To increase protection, you can stick on a single-layer surface fiberglass material.

Impregnation with olifa

Olifa oil is frequently utilized in daily life. provides the tree with antiseptic qualities and protection against humidity. Use the following technology when applying the composition to the floor or any other surface:

  • It will be necessary to apply a roller and brushes, the Olifa needs to be heated to 60 degrees, to work with it with caution;
  • The composition is applied to the entire surface so that the protection is high -quality cannot be passed, the edges are processed especially carefully;
  • Drying is carried out forced, a building hairdryer is suitable for this;
  • The cooled Olifa is heated again, and impregnated in several layers until it stops absorbing.

A base like this can be painted and varnished using techniques where olifa is used in the composition.

PVA glue coating

This method is typically applied when safeguarding the plywood products against the onset of rot. Rather than soaking the plywood on the floor, this is the best option.

Using olifa, the work process is comparable. Applying the tool continues until the coating no longer absorbs it.

It is not possible to expedite the drying process. The layers must naturally dry; in terms of dates, this usually takes one week.

Soaking plywood with the appropriate materials is essential to preventing moisture damage and decay. Choosing the best soaking solutions, such as water-based sealants, epoxy resin, and penetrating oils, will be made easy with the help of this guide. We’ll go over the benefits and drawbacks of each technique, how to use them successfully, and advice on how to guarantee enduring protection.

Useful for interior work; gauze can be used in place of fiberglass. Follow the following plan of work:

  1. Grinding plywood is carried out, after dirt and dust are removed.
  2. It is required to apply a suitable varnish, it is impossible for the composition to contain epoxy resin and polyester.
  3. After a two -hour drying, the base will be possible to stick fiberglass fabric, it is necessary to glue it exactly without flaws.
  4. Next, two more layers of varnish are applied.

Warming the surface will not speed up the drying of the varnish.

Epoxy resin

When selecting a plywood for a tool like this, it’s important to consider its type. If the product is intended for street use, avoid selecting plywood that bears the FC label, even though it’s the best variant of the FSF.

A component specified by the manufacturer on the packaging is combined with epoxy. Keep the composition from becoming overly liquid. It is advised to apply a two-layer coating after applying the solution to the entire base.

Because of its high cost, the material is not as frequently utilized in daily life.

Which impregnation is better to buy for plywood

There are numerous types of moisture-resistant impregnation for plywood available on the market. The mixture might contain olifa, linseed oil, and other components that help produce a high-quality outcome. Mastics are also employed, but they are challenging to operate.

It is crucial to ascertain whether keeping the original base color is desired or if it is necessary to change its color. You can achieve any shade, from gray to red, with Nitroemali.

Subsequent processing of plywood to maintain moisture protection

Weather factors alter the material’s quality regardless of the dependable protection employed. If the veneer layers were not securely bonded together, the layer may eventually crack and crumble. Protecting the ends that come into contact with water more frequently is very important. Plywood sheets should only be used in places like roofs that are protected from direct water damage. The sheets won’t be able to tolerate being wet all the time.

If regions with a damaged coating layer were discovered, the issue needs to be fixed right away. You must polish the site to prevent the deterioration process from continuing beneath a fresh layer of protection rather than merely applying a fresh coat of impregnation. The operation of plywood will be greatly extended with the help of such a lesions correction.

Than to soak the plywood for the floor and how best to protect the plywood from the appearance of mold

Putting plywood under linoleum for bathroom or toilet flooring, where different impregnating compounds can be used to achieve higher humidity. The requisite compositions that are required are as follows:

  • Olifa;
  • Varnish;
  • Paints;
  • Flax flowing material.
