Chipboard is mainly made of wood waste for cost reasons. Therefore, they are relatively cheap to buy in the hardware store. They consist of differently sized glued chips, which are usually compressed in three to five layers. The outer layers are always made of finer material, especially if they are used for decorative purposes such as interior fittings or furniture. Particleboard is one of the largest and most well-known sub-group of wood-chipboard materials.

Which material properties does the chipboard have?

The chipboard, although wood is the main component, is considered to be a non-absorbent substrate, since it initially absorbs hardly any water and only begins to swell when a larger quantity of water begins to form. If you want to be on the safe side, use a waxed chipboard, into which no moisture can penetrate. Wood "works", however, so there are some differences compared to plastering "non-working" materials.

Where are chipboard used?

A chipboard is often used indoors, for example, to realize a partition wall between the basement stairs and the stairs in the living area. In general, it will not be necessary to additionally plaster the chipboard with gypsum plaster before plastering. Chipboard can be plastered like most building materials, but there are some special considerations.

Before details are given in the following, however, it should not go unmentioned that in addition to the use of chipboard there are other ways that dividers can be pulled. Further information can be found in the article by Dipl.- Ing. (Architecture) Corona Zoller on baulinks.de. Surely there is a procedure that best suits your needs.

What do I have to consider before plastering?

Since substrates such as drywall have a different suction behavior, they should be provided with a primer before plastering. If you apply the plaster directly to the chipboard, cracks may form. Bonding primer and plaster net can prevent this.
Primer is a means that – as the name suggests – ensures that the plaster remains on the chipboard. Explain your project to a hardware store employee and let us advise you accordingly.

Even plaster can be purchased at the hardware store, but you must generally here at least 10 square meters decrease. It pays to ask a construction company for smaller areas first. This plastic mesh will later be placed between the plate and the plaster so that it does not break. The fabric is incorporated into the plaster application "wet in damp". Then the top coat is applied over the plaster net. Experts recommend that the individual sheets of the top coat should overlap by about ten centimeters. These additional values ​​should be added in advance to the dimensions of the area to be plastered in order to have enough material at hand.

With chipboard there is a risk that they will bulge due to the one-sided application after some time, which may cause a flaking of the plaster – also for this reason, a stabilizing primer is recommended. For the primer dilute emulsion paint, any adhesion promoter or certain paints in question. What you should use depends mainly on which coating you want to use later. Incidentally, this must be explicitly suitable for the chipboard substrate and have a certain elasticity.

How do I touch the plaster?

Plaster is usually made of mortar with fillers or additives such as sand, polystyrene and a binder. The different types of plaster are distinguished on the basis of the binder, ie gypsum, lime, cement or combinations such as gypsum lime or lime cement. There are also mineral clay plasters and organic binding resin plasters.

A special interior plaster has the advantage that it improves the indoor climate by absorbing excess moisture from the room air. It serves as a base for subsequent paintings or wallpapers. If you have chosen a supplier for the products of the primer, then you should also obtain the component for the plaster from the same manufacturer, since the components of a system are optimally matched to each other.
Putz products, which are primarily intended for the plastering of masonry, typically have a different profile than plaster, which is to be applied to wood. Often, the plaster is a synthetic resin product, which greatly restricts the flexibility of the material from the outset. For this reason, in any case, for safety's sake, you should attach the described mesh (plastic gauze) to the chipboard base to prevent the formation of cracks and unevenness at the joints of the chipboard.

Plaster is mixed with clean cold water in a mortar bucket or bucket. Pay attention to the specifications of the respective manufacturer on the packaging of your products. After mixing the mixture lump-free, let it ripen for a few minutes. Then the whole thing has to be stirred again. Since mineral abrasives chemically set, so become solid, you should never mix more mass than you could process within 60 minutes. Small tip: It is quite possible to color your plaster individually. Just add the tinting color of the plaster mixture. It is important that you then stir thoroughly and long until no more color streaks can be seen. Walls can only be completed by the use of colorful plaster, which offers an interesting alternative to wallpaper. What are the advantages and disadvantages of plastered or wallpapered walls, you can refer to the guide of haus-xxl.de.

What do I have to consider when plastering?

Successfully plastering a chipboard is not rocket science. What is needed for this?

  • a little skill
  • (at best) exercise
  • a good preparation
  • suitable tool

Not only in compensation work, but also in the use of chipboard with uniform thickness, quick cleaning strips help to achieve a clean result. In order to plaster vertically, you should apply fast plaster strips to the chipboard wall at a distance of 1.5 meters. These are also known by the term "plaster rails". Using the vertical gauges, pull the applied plaster flush with an aluminum rail. To secure the edges of the chipboard panels, you can also use skirting and corner protection profiles.

The mixed plaster is carried in sections on the wall. You must pay attention to apply the coating plaster in a suitable thickness, otherwise it could possibly "shine through" the structure of the network used after drying the plaster. For plaster based on synthetic resins, there are also special plasticizers that can significantly increase the elasticity.

Then they pull off fields between the quick cleaning strips with a grape box. Once the one or two-ply applied plaster has tightened something – pay attention to what the manufacturer recommends – you can structure it. After all cleaning work has been done, you should ventilate the room in which the plasterboard is plastered for a few days well.This allows the water to evaporate from the new coating.

DOS

  • Use a plaster net or primer to prevent cracks
  • Mix plaster mixture without lumps
  • Customize plaster with tinting color to your own color preferences
  • After completing the cleaning work, ventilate the room well for several days

Don'ts

  • When choosing plaster and primer products from different systems / providers use – better match component
  • Do not let the plaster mixture ripen after stirring – let it soak for a few minutes

I need this for plastering a plywood board:

  • Buckets or mortar tubs
  • water
  • mortar mix
  • Cleaning net or primer
  • Quick cleaning strips / plaster rails
  • aluminum rail
  • Base completion and corner protection profiles
  • Trowel / grape box

What does a chipboard cost?

Chipboard is available in different versions. Variable properties are:

  • edge processing
  • moisture resistance
  • format
  • Strength

When it comes to edging, you have the choice between "smooth edges" and "tongue and groove". Particle boards with smooth edges are laid joint to edge. Especially the cutting of the panels is easy to do, as all edges are compatible with each other. However, it should be noted that in the case of unevenness in the ground, there is no uniformly smooth surface of the covering. For such an application chipboard with a tongue and groove edge processing are better suited. The positive connection creates a consistently flat surface. When cutting it is important to note that the connector always consists of a groove and a spring edge and therefore the plate must be processed in the appropriate place.

The labels P1, P2 and P3 provide information on the moisture resistance and strength of the chipboard. For example, chipboards classified as P1 and P2 are suitable for use in the dry area, while chipboard marked P3 is used in the wet area.

To be as flexible as possible, there are chipboard in various formats and strengths. Large formats up to 6700 × 2500 mm are used especially for covering large areas. Often, however, smaller, more manageable formats are needed, which are easier to handle. The following sizes are available in terms of plate thickness: 2.5mm, 8mm, 10mm, 12mm, 13mm, 14mm, 15mm, 16mm, 18mm, 19mm, 22mm, 25mm, 28mm, 32mm, 35mm, 38mm, 40mm and 80mm.

In principle, these properties have the following effect on the price of the chipboard:

characteristic price
edge processing Design smooth edge <design tongue and groove
moisture resistance P1 <P2 <P3
format The bigger, the more expensive
Strength The stronger, the more expensive

Table 1: Effects of properties

On bausep.de there is a good example for the development of the price of a chipboard P3 with tongue and groove edge processing in the format 2050 x 925mm depending on the plate thickness:

Available strength Price per m²
13 mm 3,69 €
16 mm 4,20 €
19 mm 5,10 €
22 mm 6,10 €
25 mm 7,00 €

Table 2: Exemplary price development depending on the plate thickness

Dry area versions with smooth edges are cheaper according to Table 1.

It should be noted that each format or thickness is not available for every edge treatment.The properties are mutually dependent.
