Acrylic «Woodworm» often sold in buckets, ready-made, which saves a lot of time. However, it is best to purchase the dry mixture. First, the cost of dry mortar less than ready. Second, it is applied to the work surface much easier. And, thirdly, the color of the final solution is a rather complex process, which requires the use of special machines.
The cost «Bark» is about $ 15 for one bag, which is usually enough to finish 6-8 square meters.

Decorative plaster «Woodworm» is a dry mixture of acrylic or plaster base, which contains fine granules of marble or mineral aggregate, and composite plaster. Grit plaster “Woodworm”, which affects the appearance of the facade, depends on the size of these granules.
To perform work you will need the following tools:
- plastic grater;

- drill with a special nozzle with a mixer;
- metal spatula.
Finish facade plaster “Woodworm” includes four stages:
- preparation of the working surface;
- preparation of the solution;
- applying a mixture;
- tinting color.
Preparation of the working surface is one of the most important stages. For starters, the front surface is carefully leveled with cement-sand plaster. Plastering should be carried out to a pre-established lighthouse profiles established using the level. Their installation must be not less than 100-150 mm.
Between beacons throws cement-sand plaster, which further tighten the rule. If the tie remains, the defects, they were treated with a poluter or float. After about 3-4 hours the prepared surface and rubbed in a circular motion.
The next day, if need be, you can spend another grout. In that case, if the grout had to wear in the warm season, it is advisable to water it every day with water, to avoid cracking.
If necessary, this type of plaster can be used for facade finishing, insulated with foam polystyrene or Styrofoam. In this case, the surface of the insulation is required to pre-process adhesive, on top of which are placed reinforcing mesh.
After drying, cement-sand layer, you can start preparing the plaster “bark Beetle” and its application. At this stage special attention should be paid to the correct timing, after all, facing one wall need to have time to spend at one time (since joining the new site should be carried out with not yet dried the previous one). Through these actions, the working surface will have a smooth structure with no visible differences.
The process of preparing the plaster involves the following steps:
- first we need to take a clean container;
- then fill it with room temperature water in quantity specified on the package;
- then gradually pour the dry mixture while thoroughly stirring (to avoid lumps);
- after the mixture was drained, the solution continue to stir until then, until it becomes homogeneous;
- capacity then carefully closed for 10-15 minutes and then mix the solution again.
When using «Woodworm» for much more precise application is recommended to use a metal spatula. Perhaps the most difficult part of the work lies in the fact that complied with the required layer thickness corresponding to the grain size. In itself, the plastering is almost no different from putty is that the solution should stretch over the surface until, until you appear a small furrow.
To get the spiral texture on the fresh plaster light movement is carried out with a plastic trowel. It is worth to mention that, if the material is not dry, the result may not be too satisfied, but as soon as the plaster dries, it is significantly transformed.
Then again, the surface is polished with a plastic float, but stronger movements. During operation it is necessary to ensure that the plaster from sticking to the grater. In conclusion, carefully rubbing all joints.
In most cases, facade plaster «Woodworm» available in two colours – white and grey. If you have the desire to give the material a different shade, during the preparation of the mixture should be added a special dye. In addition, the plastered surface can be painted with acrylic, latex or silicone paint.
In that case, if the dye is added to the plaster, one batch may differ from another in its color. To get rid of this not too easy, but if the wall surface is additionally colored paint, and don’t need. All batches simply must have the approximate shade, which can then be corrected.
The biggest challenge when painting decorative plaster is that paint must not fall into the furrow «Bark». For more accurate work, use a roller with a short NAP, which lightly pass over the entire surface texture. The result will be quite impressive.
In another method of painting «Bark» the color is added not in the plaster, and a latex or acrylic primer. Then primed treated working surface. Given that the primer itself is enough liquid it can easily penetrate into all the pores «Bark», carefully progresiva. As your drying, the primer forms a permanent layer. The result was a more attractive, apply the primer should be in two layers.
