The plaster mortar mixture delivered to the construction site must be unloaded into a loader-mixer or into other containers, provided that the specified properties of the mortar mixture are maintained.

Instructions for carrying out work

SNiP 3.04.01-87 pp. 3.1, 3.3, 3.7-3.11, 3.15, 3.37, 3.18

Plastering work must be carried out at positive temperatures environment and the surfaces to be finished are not lower than 10 °C and air humidity is not more than 60%. This temperature in the room must be maintained around the clock for at least 2 days. before the start and 12 days. after completion of work.

Finishing work must be carried out in accordance with the work project (WPP) for the construction of buildings and structures. Before finishing work begins, the following work must be completed:

The premises to be finished were protected from precipitation;

Waterproofing, heat and sound insulation and leveling floor ties have been installed;

Seams between blocks and panels are sealed;

The junctions of window, door and balcony blocks are sealed and isolated;

Light openings are glazed;

The embedded products were installed and the heat and water supply and heating systems were tested.

Plastering and cladding (according to the project) of surfaces in places where embedded products of sanitary systems are installed must be performed before the start of their installation.

Plastering over substrates with rust, efflorescence, grease and bitumen stains is not permitted. Dust removal of surfaces should be done before applying each layer of plaster compositions.

The strength of the foundations must be no less than the strength finishing coating and comply with the design. Protruding architectural details, places where they meet wooden stone, brick and concrete structures must be plastered over a metal mesh or wire attached to the surface of the base; wooden surfaces - on shingle panels.

Internal surfaces of stone and brick walls built using the freezing method, should be plastered after thawing the masonry with inside at least half the thickness of the wall.

When plastering brick walls at an ambient temperature of 23 °C and above, the surface must be moistened before applying the solution.

When installing single-layer coatings, their surface should be leveled immediately after applying the solution; in the case of using trowels, after it has set. When installing a multi-layer plaster coating, each layer must be applied after the previous one has set (the covering layer - after the mortar has set). Leveling the soil should be done before the mortar begins to set.

The acceptance certificate for completed work is drawn up after the contractor has fulfilled its obligations. The act is not an independent document, but serves as an annex to the work under the contract. It is part of the procedure for accepting the results of work and serves as the basis for final settlements under the contract agreement between the customer and the contractor.

Rules for drawing up an acceptance certificate for completed work

This document does not have a standard, legally approved, uniform template, so it can be drawn up in free form or according to a template developed at the enterprise. The act is printed on a regular A4 sheet in two copies - one for each party. After all work is completed and cooperation on the project is completed, the act is transferred to the accounting department of the customer enterprise for drawing up on its basis financial statements, including accounting for expenses incurred and reducing income tax.

When drawing up the act, you should adhere to the rules and regulations of office work developed for this type of document. In particular, the standard act must necessarily contain

• information about both parties to the contract,
• brief information about the contract itself under which the work was carried out,
• Name of works,
• date of work,
• quality and cost of work performed.

The act must be signed by the heads of both organizations and stamped with seals (since 2016, the presence of seals and stamps for legal entities is not a legal requirement, so the absence of a stamp is not a strict necessity)

In the case of a large volume or special complexity of the work performed, a specially created commission, which includes representatives of the contractor and the customer company, may be involved to assess their quality, as well as draw up a report.

If absolutely necessary, a third party may be involved in the form of experts or representatives of regulatory government agencies. Their work must be recorded in a document, and each expert must also sign the document.

Why is this act needed?

The work acceptance certificate is a kind of guarantee against the occurrence of legal disputes and disagreements. If such proceedings nevertheless arise, the act becomes an evidentiary document. The court may regard the absence of an act as a disregard for the legally established procedure for the delivery and acceptance of work, which in turn may lead to the imposition of penalties by regulatory agencies.

A table is drawn up from the list of completed works. The document also states that the work was completed properly and the customer has no complaints against the contractor.

In cases where the customer is dissatisfied with the quality of the work performed, this should also be reflected in the report with a detailed listing of the identified deficiencies, as well as an indication of the time frame for their elimination.

Instructions for drawing up the acceptance certificate for completed work

After signing the acceptance certificate for the work performed, all claims can only be considered in court.

Many people, before starting repairs, think whether they need to carry out plastering work, this is due to only one fact - ignorance of execution technologies repair work and the consequences of not complying with them. - this is the process of leveling any surfaces vertically and horizontally using special dry mixtures (gypsum, cement-lime plasters). The main task of applying plaster is to obtain the correct geometry of the premises: setting angles of 90 degrees, leveling the width doorways and slopes, making the walls parallel, obtaining a single and even plane.

Based on the quality of execution, plaster is divided into three categories: simple, improved, high-quality.

Document regulating the quality and technology of these works -

All these requirements apply to both manual application plaster, and for machine.

Tolerances for plastering work

Parameters and properties of plaster	Simple	Improved	High quality
Deviations from the vertical by 1 m, no more	3mm	2mm	1mm
Maximum deviation from vertical by the entire height of the room	15mm	10mm	5mm
Number of unevenness per 4m2, no more	3	2	2
Depth of irregularities, no more	5mm	3mm	2mm
Deviation from the horizontal by 1 m, no more	3mm	2mm	1mm
Base moisture content, no more	8%	8%	8%

Thickness of the plaster layer (plaster)

When following the technology of plastering work, it is worth paying special attention to the thickness of the plaster, both the minimum and the maximum permissible!

These values ​​depend on the plaster mixture and are different for each. For example, for machine-applied gypsum plaster Knauf MP-75, the thickness of the plaster layer should be in the range: from 8 mm to 50 mm (for one sweep). If it is necessary to apply plaster with a thickness of more than 50 mm, then this should be done 2 times with drying and re-priming the first layer. See this information in the descriptions of plaster mixtures and, better yet, on the manufacturers’ websites!

Permissible thickness of the plaster layer

Based on these parameters and the curvature of your walls, you should select the appropriate mixture.

This is a very important parameter, the observance of which determines the quality and durability of the plaster! If this requirement is not met, cracks may appear on the surface and even detachment from the base.

Key excerpts from SNiP for plastering work

3.15. When plastering brick walls at an ambient temperature of 23 °C and above, the surface must be moistened before applying the solution.

3.16. Improved and high-quality plaster should be performed along beacons, the thickness of which should be equal to the thickness of the plaster coating without a covering layer.

3.17. When installing single-layer coatings, their surface should be leveled immediately after applying the solution; in the case of using trowels, after it has set.

3.18. When installing a multi-layer plaster coating, each layer must be applied after the previous one has set (the covering layer - after the mortar has set). Leveling the soil should be done before the mortar begins to set.

3.19. Sheets of gypsum plaster must be glued to the surface of brick walls with compositions corresponding to the design, placed in the form of marks, measuring 80x80 mm over an area of ​​at least 10% along the ceiling, floor, corners of the vertical plane every 120–150 mm, in the spaces between them at a distance of no more 400 mm, along the vertical edges - in a continuous strip. Sheets to wooden bases should be secured with wide-headed nails.

3.20. Installation of gypsum moldings should be done after the base of plaster mortars has set and dried. Architectural details on the facade must be secured to the reinforcement embedded in the wall structure, which is previously protected from corrosion.

We also suggest that you familiarize yourself with (installation of mesh, mixture consumption, removal of beacons, special primers, plastering on beacons, etc.).

These works are used for various building materials: monolith, brick, foam concrete using special primers for each type of material. Before applying plaster on metal and wooden surfaces, it is necessary to make special preparations (fill a metallized plaster mesh, prime the surface with a special primer), we do not recommend plastering work on such surfaces, it is better to resort to using the dry leveling method - installation of gypsum plasterboard sheets. You cannot plaster over the plasterboard sheets themselves, since gypsum board sheets can become deformed under the influence of moisture; if your plasterboard partitions are assembled crookedly, it is better to redo them than to level them with plaster.

None of the current SNiPs contain regulations for the installation of plaster mesh, so this process is purely advisory in nature.

We recommend using plaster mesh with a plaster layer thickness of 50 mm or more, as well as on walls made of foam concrete, since there is a high possibility of cracks appearing there.

The most popular area where work completion certificates (WCPs) are most often used is the construction industry. These are not necessarily forms KS-2 and KS-3; often the customer and the contractor need acts in a simplified form, which is not regulated by the legislation of the Russian Federation.

We present to you the largest selection of reports of completed works in construction. If you haven’t found the act you need, then leave a comment and we will send you the required form as soon as possible.

Almost everyone, both owners of new buildings and secondary housing, encounters plumbing services. This type of service includes: installation/dismantling of plumbing fixtures, installation of heated floors, adjustment and connection of finished equipment (water treatment system, water heater, station high blood pressure), connections washing machine and much more - all this is included in the list of plumbing services.

AVR is a confirmation and basis for payment, which you can download for free from the link below.

Certificate of completed electrical installation work sample

The problem with our legislation is that any Vasya Pupkin can perform electrician work when renovating an apartment, without having the proper qualifications and education.

And no matter how sad it may be, in modern economic realities this work performed by painters and plasterers. Only the consequences of such work can be disastrous and you will be lucky if it is just smoke or the fire is localized at an early stage

But these are all lyrics, we are interested in the act of performing electro installation work, you can download it from the link below.

Certificate of completed work by an electrician

Similar to the previous document, however, the customer and the contractor are not legal entities. Accordingly, no details, VAT, stamps or other standard fields for acts based on KS-2.

Certificate of completed work on installation of suspended ceilings

Over the past 10 years, stretch ceilings have ceased to be know-how, becoming the “gold” standard. Due to its practicality and long service life, companies provide up to 15 years of warranty on it.

But here, read the contract carefully, since often the interpretation is as follows: they say the canvas is 25 years, and the work performed is 1 year.

In any case, you will need an AVR for installation suspended ceilings, which you will download from the link below.

Certificate of completed installation work sample

Installation in construction can mean anything, from the installation of primary converters to metal structures. Therefore, in the corresponding document we indicate what the installation was, who performed it, and other standard fields. You can download the AVR you need from the link below.

Certificate of completion of finishing work sample

Finishing work involves a wide field of activities: plastering, putty, installation of MDF panels and much more. Therefore, when an apartment or office is being renovated, intermediate reports of completed finishing work are drawn up. For example, if you completed plastering work on room “N”, signed the AVR, you will receive a monetary reward.
