Technology of putting "bark beetle" plaster: features and stages of works

One of the most interesting, original, cheap and simple options in drawing for facing of surface textured plaster “bark beetle” is considered. By means of this material which is applied as to outside, and interior finish it is possible to create unique, picturesque and long-lasting surface. The technology of putting “bark beetle” plaster is in detail described in this article.

Technology of putting “bark beetle” plaster: preparation of the basis

“Bark beetle” plaster can be applied on previously prepared brick, plasterboard, wood-shaving, concrete beds, sandwich panel and on heater layer.

Before performance of facing works it is necessary to clean carefully surface from old finishing, oil stains, dirt and dust. If the basis has essential roughnesses and cracks, it should be leveled with use of plaster, lime or cement slurry for plaster of walls. Proportions of the making components have to be observed strictly to receive finishing material of appropriate quality with necessary strength characteristics.

Helpful advice! For sealing of joints and big cracks, they need to be embroidered previously by means of the Bulgarian, and then to close up plaster putty.

If wall decoration is carried out indoors with the increased humidity level, then the surface surely should be processed antifungal structure which will prevent formation of fungus and mold.

To create good adhesion of the basis and future plaster, the leveled surface should be processed primer, using the roller, brush or paint spray gun. It will also regulate the absorbing ability of the prepared surface, will provide uniform drying of decorative plaster layer. To prepare future color shade of surface it is possible to add coloring pigment of necessary shade to primer. Under “bark beetle” plaster it is better to use dense acrylic primer which is capable to prevent excessive absorption of moisture during operating time with this decorative mix.

Concrete and cement and limy external walls do not need processing by soil mix. For creation of good adhesion will be to moisten carefully surface with water for hour prior to carrying out facing works with the plaster help enough.

It is necessary to apply basic layer of plaster mix no more than 2 mm thick on dry layer of primer on which full drying about 40 min. will be required at temperature of 20 degrees. It at the same time should be condensed and rubbed clean. It will play role of reason for future texture.

Description of technology of plaster of facade for heater

Many owners of country and owner-occupied dwellings aim to make rooms the warmest. For this purpose exterior finish of walls by means of heater which needs to create high-quality protection against negative impact of the external environment is very often carried out. For this purpose it is necessary to use front plaster which to be put over thermal insulation material.

The technology of plaster of external walls assumes creation of wet facade which consists of heater, armoring lattice and textured plaster.

As heater for walls outside of the house under plaster expanded polystyrene or mineral wool can be used. The first material is inexpensive and quite simple product in mounting. It is used for heat insulation of concrete, slag concrete, haydite concrete and brick facades.

More durable, nonflammable and “breathing” heater mineral wool in the form of two-layer basalt or diabasaltic plates is considered. It is reasonable to use this material for walls from haydite concrete, gas-silicate, gas concrete and wooden bar.

The technology of warming of facade under plaster mineral wool or expanded polystyrene assumes use of the special gluing structure which is applied with thin layer on the heater basis. Further, plates by the principle of brickwork fasten to wall surface.

After full drying of glue structure, plate of heater it is necessary to fix in addition, using dowel umbrellas. Over heater it is necessary to fix armoring lattice from fiber glass by means of plastic fastenings. Three days later it is possible to start performance of plastering of surface which principle same, as well as for finishing of internal rooms on beacons.

Here it is possible to use at once front plaster “bark beetle” which video of technology of drawing, will in detail show the sequence of actions.

Helpful advice! After finishing by building facade “bark beetle” plaster, it needs to be protected for two days from direct influence of ultraviolet rays and rainfall.

Features of plaster of walls on beacons

Prior to final finishing of surface it is necessary to prepare the basis. Alignment of walls is considered the main action. One of the most popular and efficient ways is performance by the hands of plaster of walls on beacons. Video will demonstrate the sequence of performance of actions.

Before starting works it is necessary to prepare special materials and tools. First of all it is necessary to buy beacons for plaster of walls which will act as limiters. They represent metal or plastic sections with openings. Depth of product is 6 or 10 mm which is selected depending on wall deviation, length — 3 m. In form distinguish T and the L figurative products.

If walls rather equal or have insignificant roughnesses, it is possible to execute plaster of walls without beacons.

Also, construction mix for plaster of walls is required. It is possible to buy ready material, and it is possible to make the hands solution for plaster of walls. Proportions of all ingredients need to be observed strictly. For preparation of cement plaster the ratio of cement and sand is equal to 1:2-3. For limy mix it is necessary to take lime and sand in the ratio 1:2-4. The clay structure is received by mixing by 1:3-5 clays and sand. And for receiving cement of plaster for plaster of walls, proportions of lime, plaster and sand make 1:1:2.

As additional tools will be necessary:

  • palette;
  • plumb;
  • self-tapping screws;
  • dowel;
  • rule;
  • tape measure;
  • scissors for metal;
  • level;
  • the perforator for mixing of mortar.

Depending on the chosen mix and proportions of solution additional tools from different materials will be necessary for plaster of walls the hands, perhaps: tree, plastic or metal brushes.

How to choose plaster for walls

Plaster for walls is selected depending on basis type. For concrete surfaces it is better to give preference to cement slurries or limy mixes with addition of cement which number influences plaster life cycle. Any plaster will be suitable for brick walls. However for the best adhesion of the concrete or brick bed and working solution it is necessary to establish armoring lattice for plaster of walls. It surely should be mounted when it is necessary to impose plaster coat more than 5 cm.

Finishing of wooden surfaces can be carried out by plaster and limy mix, or solution with addition of clay as the plasticizer. However it is not necessary to exceed admissible norm of this component which can promote further education on wall surface of cracks. Plastering of wooden surface is surely carried out with use of armoring lattice for plaster of walls which price depends on product material.

For finishing of gypsum block it is possible to use plaster or lime-gypsum plaster. Cement slurries are not compatible to plaster surface. Here additional mounting of grid is not required.

The bases from foam concrete blocks and gas-blocks which have very low adhesion are considered as the most problem. Therefore to provide long-term and reliable coupling of the basis and plaster it is necessary to fill grid under plaster of walls and to use solutions with special additives.

Many specialists give preference to plaster blend which has the best utilization properties. It does not shrink, thereby prevents clinking. Also, this material creates additional heat insulation and sound insulation. All subtleties of work with this structure are in detail stated in video “As It Is Correct to Plaster Walls Plaster Plaster”.

Important! Plaster plaster cannot be used for concrete beds which components, reacting with plaster, push away it. Such plaster will very quickly disappear.

How to expose beacons for plaster of walls?

For a start it is necessary to check walls and by means of the level which is put across and verticals and to reveal all hollows and ledges. Before establishing beacons for plaster of walls, it is necessary to mark surface by means of marker. It is necessary to begin with corner, having receded about 30 cm from each party, having planned places for extreme indicators. To draw the vertical line. The distance between the neighboring beacons has to be 160 cm. It is less, than length governed.

Helpful advice! It is not necessary to divide wall surface into unequal parts. If there are about 2 m, beacons at distance 1 m from each other is better to arrange.

For creation of horizontal mark, it is necessary to recede from floor height 15 cm and to draw the line perpendicular to vertical marking. In points of intersection of lines to execute openings and to hammer dowel. Further it is necessary to stretch through them cord. From the received line to measure 235 cm (with room height of 2.65 cm) and in the place of crossing with vertical lines to create openings and to hammer dowel.

After marking, the surface should be cleaned thoroughly from dirt and dust and to ground. It will create good basis for future plaster and will prevent education on wall surface of fungus and mold.

After the wall dries, it is necessary to start installation of beacons for plaster of walls. Here it is necessary to be extremely attentive. Exterior of ready surface will depend on it. The wall needs to put the metal beacon vertically to the place noted earlier. Further the most upper screw is twisted. The plumb which will control arrangement of the subsequent screws and respectively placement of profile is attached to it. The main objective consists in alignment of profile. It will depart from surface in places where there are hollows and to adjoin densely on hillocks.

The operations procedure is in more detail shown on video “How to Establish Beacons for Plaster of Walls”. All above-stated operations are performed for each beacon.

There is also other way of exposure of beacons:

  1. It is necessary to prepare small part of plaster mix. It is better to choose plaster structure which quickly grabs.
  2. To apply solution on wall in places of horizontal and vertical marking with thickness exceeding depth of disk-seal profile.
  3. To put the beacon vertically to wall and to press it into plaster mix, having carried out along it by the rule.

Putting plaster on surface

Now it is necessary to prepare working solution, strictly following the instruction on material packaging. Mix is applied between beacons by means of the wide palette with small excess to avoid formation of hollows. Now, using the rule established on beacons alignment of plaster coat is carried out, moving from below up and periodically shaking it here and there, evenly distributing solution on wall. This manipulation needs to be made several times before receiving equal and smooth wall. The cost of plaster of walls for 1 sq.m depends on type of the processed surface and the area of the basis.

For further decorative plaster of walls it is necessary to remove disk-seal profile. It is possible to make it only in several hours after to grab basic layer. The formed emptiness are closed up by means of the wide palette and plaster.

The final stage is the plaster finish. This action should be executed before full drying of mix. As finish mix, more liquid on consistence, is used. It is put and smeared by thin layer on wall of 1 m ². So each subsequent square is rubbed clean. Work is performed without breaks.

Alignment of the basis in such a way can be executed independently, or it is possible to resort to the help of the specialist.

Main subtleties of preparation of “bark beetle” plaster

“Bark beetle” plaster can be bought in the form of dry or ready mix. For preparation of working solution from dry material it is necessary to observe accurately proportions of ingredients, temperature condition and the sequence of actions. All information is in detail stated on packaging.

At first it is necessary to measure necessary amount of water which temperature has to be within 21-23 degrees. On 1 kg of dry mix to be necessary about 250 ml of water. However, it directly depends on components of plaster and producer of material. Working solution should be prepared in container, convenient for further works.

It is necessary to add the measured amount of dry powder to water. Mixing of ingredients can be carried out trowel manually. But quicker and more conveniently to prepare mix, using the construction mixer which should be turned on on average turnovers. Hashing should be carried out until weight does not become homogeneous without the remains of solid matter, lumps and excess moisture on the surface of solution. The consistence of working solution has to be similar to dense sour cream.

If solution is too dry, it will create additional difficulties during its drawing. It will constantly roll down from trowel, increasing at the same time mix consumption. Too liquid solution will flow down from surface, leaving unpleasant drips. Besides, by means of liquid solution it will not be possible to create the necessary impressive relief characteristic of “bark beetle” plaster.

How to apply decorative plaster “bark beetle” on walls?

Before performance of facing works it is necessary to get acquainted in detail technology of putting decorative plaster on surface which has to be in advance prepared (cleaned and leveled). The quality of preliminary finishing will influence extent of obtaining the impressive drawing characteristic of “bark beetle” plaster.

Works on plaster of walls are performed completely, i.e. one wall needs to be covered at one time, without waiting for drying of the put sites. Only in this case it is possible to receive monolithic surface without seams and differences.

Helpful advice! Before performance of work it is necessary to paste painting adhesive tape on all next surfaces to protect them from plaster.

There are two ways of putting decorative plaster: manually and by means of special mechanisms.

Before applying “bark beetle” plaster in the manual way, it is necessary to prepare the necessary tool. For works the palette from stainless steel and plastic grater or trowel for creation of the impressive drawing will be used. On the palette small part of solution is imposed.

Works begin with the bottom right corner. Plaster is applied with the tool at an angle the 60th hail. concerning the processed surface ranks, on vertical or horizontal, taking all wall. Plaster stretches to thickness of layer which depends on the size of the biggest grain in mixing ratio. It will be visually visible when on surface scratches and grooves begin to be formed.

Helpful advice! If the size of wall rather big, then it it is necessary to divide into two parts, using painting adhesive tape.

If finishing of wall is not finished, but there was need for break, then it is necessary to stick with painting tape the place of the last imposing of plaster. When works are resumed, the tape is removed, and the layer is a little cut off.

Before forming of the impressive drawing, it is necessary to allow surface to dry a little that plaster did not stick to hands. On it about 20-40 min. depending on temperature conditions are required. For creation of characteristic strokes the plastic grater is used. She should be kept plainly, slightly in pad to the processed surface. Depending on what actions will be made by means of this tool, exterior of impressive ornament will depend. If the surface begins to dry quickly, it can be sprinkled water. Such procedure will provide extra time for performance of finish.

After the end of forming of the drawing, without waiting for full drying of plaster, it is necessary to jam all surface that connection sites were not looked through without pressing.

The impressive surface created by means of “bark beetle” plaster dries at temperature of 10-30 degrees and relative humidity no more than 80%. After final drying of surface it is possible to start its coloring.

Pluses and minuses of the mechanized plaster of walls

When it is required to perform facing works on big surface, it is reasonable to use the mechanized plaster of walls which price is defined by the sizes of surface and type of finishing material. So, it is necessary to apply paint spray gun to putting primer, and plaster can be applied, using the automatic machine.

The nozzle of the automatic machine should be brought closer to wall as much as possible. It has to be strictly perpendicular to the basis. The operator evenly distributes the weight moving under high pressure. Here it is necessary to be extremely attentive and accurate not to lead to formation of defects.

Let’s consider positive aspects of use of the mechanized way of plaster of walls:

  • it is possible to achieve the minimum thickness of plaster coat that allows to reduce material consumption;
  • this way provides uniformity of causing structure, its good adhesion with wall and the maximum durability of ready surface;
  • that solution moves continuously strong step-by-step coupling of mix with the basis is provided;
  • mix which is applied mechanically excludes formation of air bubbles, finding of dry lumps and foreign inclusions.

Alignment of walls happens manually. It is possible to receive the impressive drawing by means of the grinder with fleecy circle. However it is not always possible to receive pronounced relief of surface.

Plaster of walls allows to perform in the machine way works on facing 4 times faster, than manual way. Thanks to the distributed and short-term putting solution on surface there is its uniform hardening that excludes clinking.

The main lack of way is use of the large-size equipment which it is not always possible to deliver easily to the destination.

Ways of creation of impressive surface

The type of the drawing on ready surface will depend on the nature of the movements made by grater on the plastered wall. Let’s consider in more detail actions which help to achieve this or that relief.

For obtaining the classical drawing corroded bug bark beetle of tree, it is necessary to carry out circular, arc-shaped non-uniform motions diversely, slightly pressing the tool.

To receive imitation of uneven surface of stone, so-called ornament “travertine”, it is possible making short abrupt movements by trowel, moving diversely. To receive ornament “stopper”, it is necessary by means of the tool from expanded polystyrene to make intensive circular motions in one direction which have to have small radius.

It is possible to create imitation of fabric surface through crosswise movements of grater. At the same time it is necessary to carry out vertical strokes from below up the long slow movement, and performance of horizontal strokes is carried out by vigorous short wave.

The drawing “rain” will turn out at commission of long continuous movements on diagonal from top to down. It is necessary to begin with the right upper corner, moving down on the left.

By means of “bark beetle” plaster it is possible to create the drawing “world map”. For this purpose it is necessary to put the first layer of material and to execute its finish in any convenient way. After drying of layer, it is necessary to put one more layer, but not evenly, and in the form of separate dabs diversely which need to be smoothed with the Venetian trowel then.

Before starting works, it is possible to watch video “How to Apply Textured Plaster for Walls”.

Features of coloring of the plastered surface

There are two options of coloring of decorative surface:

  1. Addition of coloring pigment directly in ready mix.
  2. Coloring of the plastered and hardened wall.

The first option more acceptable when using ready mix to which it is necessary to add certain amount of dye for receiving necessary shade. When dry mix is used, to calculate color dosage very difficult. In this case, it is better to execute coloring of already ready basis.

For coloring of ready surface it is necessary to use acrylic, silicate or aqueous emulsion ink which is applied by means of brush or the roller. The acrylic structure should be put not earlier than in two weeks from the date of finishing, and the silicate paint can be used in three days.

Coloring can be carried out in two steps. The first time carefully becomes covered all surface including invoice furrows. After drying of surface the second layer of lighter or dark shade which assumes coloring only of upper part of covering, excepting hits of paint in furrows is put. It is possible to achieve such effect, using the moist roller which it is necessary to take for a drive previously on plywood. Also, use of special dyes with the reflecting properties is reasonable here.

Helpful advice! If not to paint groove, it is possible to receive illusion of depth of covering.

Instead of coloring of surface, it is possible to glaze covering acrylic lacquer to which structure can be added nacre or color. It is necessary to apply such mix by means of the steel palette, completely filling all grooves on wall surface.

Strict observance of the sequence of actions when performing facing of surface by textured plaster “bark beetle” will allow to receive qualitative, long-lasting, attractive and esthetic covering which will be pleasing to the eye for many years without loss of the original state.
