How to choose the “Terraco” plaster

The material comes in bags (in the form of dry mixture) and buckets (pasty mixture). This should be considered as a ready mix have less problems to apply, but it costs more. This is due to the fact that the material is prepared with the admixture of synthetic fillers.


Most often you will meet material in white on the market, although sometimes you can stumble upon on other colors. What`s the difference? It’s simple -the mixture can have any color by your desire, and it can be done in several ways. The first is to add the dye to the plaster mass during mixing, and the second – to decorate the surface when it has dried. The main feature of material is unlimited possibilities for decoration, because “grinded” pattern can be applied in various ways: a crisscross, by circle strokes, waves or even by chaotic movements. This material is fairly simple to use and it is capable of hiding minor shortcomings that you can do in the process of applying.


Today there is a great demand for decorative plaster on the market and every manufacturer tries to extol its products in all possible ways. But in fact, if the technology was maintained during the manufacture of the material, there would be no significant difference in quality. Therefore, the choice of decorative plaster should be guided by your own taste only. Also we recommend you to look closer to the prepared sample. Imported plaster does not differ in quality from domestic producers, but it still not worth to save money. After all, the cheaper the material, the more likely that the production technology has not been maintained or it even had been made in artisanal way.


What else do you need to check when choosing “Woodworm” plaster? Well, first of all, you must know that the expense of material can vary and mostly depending on the diameter of the mineral grains included in its composition. For example, with a grain diameter of 2.5 mm, you need up to 3 kg per 1 m2 of the plaster, and with the size of 3.5 mm – 4 kg / m2.


Scope and preparation of “Woodworm” plaster

The material is used as in the finishing of the walls as well as in finishing of ceilings. It can be used on any surface that is capable of adhesion and will not bend during applying: drywall, brick, concrete, chipboard, cement plaster, etc. Woodworm is a topcoat and should be applied with a thin layer (a little larger than the diameter of grain), so do not try to fill large cracks and holes in the walls.

Woodworm applies on a flat, clean and primed surface. Therefore, if there is any paint, lime or other material, it should be removed.

Technology of Woodworm application and its preparation methods are described in detail in the instructions of the purchased material. You should be guided with precisely this prescription. But the general instructions are as follows:

  • While the preparation of a mixture of plaster it should be poured in the water and not vice versa;
  • Water should be warm, about 20 ° C;
  • the solution mixes using a drill with mixer paddle and at a low speed;
  • do not spend time for handwork, the qualitative stirring is impossible this way;
  • continue mixing until the moment when there is no noticeable lumps. After that give the material to stand for about 5 minutes and then stir it again;
  • the proportion of water and dry plaster blend, together with duration of applying the Woodworm depend on the specific make and indicated in the instructions. One mixture may already dry out in an hour, while another may lie in the vessel for three hours as and be still applicable. But if you plan to refresh it by adding a water after a while – answer’s a lemon. That is why it is important to follow the instructions from the manufacturer.


Application of Woodworm plaster

  1. Small amounts of the mixture was applied to the surface is smeared and uniform thin layer.
  2. After the material thickens (about 30 minutes) you should go over the surface with slight sliding movements of grater. It is necessary for the alignment of the layer and creating a drawing. Novices can use more simple, traditional patterns: rain, waves, circles, etc. The main thing – is confident and gentle movements, do not get too much pressure on the grater. Remember, the longer Woodworm is being rolled – the less noticeable will be drawing. Surface is become glossy and plaster effect will be lost.
  3. When working with a large surface, it is desirable to have an extra hand. One applies the plaster and the other rubs the surface. Woodworm is quite simple in application, even beginners are able to cope with this task.
  4. The recommended temperature in the working premises must remain within the range of +5 to +25 degrees. But if the mixture appears as a cover with a couple of colors, the room should be no colder than 10 degrees plus.
  5. The plaster is desirable to apply without interruption, in one go. But under compelling circumstances you should stick masking tape so the material does not dry upon the border of the applied mixture. Depending on the type, Woodworm dries in a range of 1 to 5 days. Then you can begin the painting. If it uses acrylic paint, then 5 days will not be enough, it is necessary to wait a couple of weeks. And for silicate one 3 days will be enough.

Then we check quality. Properly done work is visible at once: it comes without joints, there is no “gloss”, surface is textured. Otherwise, the material crack in several weeks may when the material has been applied incorrectly or in too thick layer.
