What is the price of the arrangement of a half -dry floor screed and how to calculate the amount?

Here at "All about Concrete," welcome! You’ve come to the right place if you’ve been wondering how much it will cost to install a half-dry floor screed and how to calculate how much will be needed. In order to prepare a level surface for flooring materials like tiles, wood, or carpet, floor screeding is an essential step. You can more efficiently plan and budget for your project if you have a better understanding of the pricing and calculation process.

Let’s start by defining a half-dry floor screed. Half-dry screed is a semi-dry mix that can be leveled right away after placement, in contrast to traditional wet screeding, where the mix is more fluid and needs to be leveled after pouring. This technique is well-liked in both residential and commercial construction because it has benefits like shorter drying times and a lower chance of shrinking.

The cost of installing half-dry floor screed is influenced by a number of factors. One important factor to consider is the area that needs to be screeded; larger areas typically result in lower costs per square meter because of economies of scale. Another important factor is the kind and caliber of the materials used. Specialized mixes or higher-grade materials may be more expensive, but they can provide better durability and performance.

Measure the floor area precisely in order to determine how much half-dry screed you will need for your project. In order to find the square footage, or square meters, multiply the length by the width. Next, decide how thick you want the screed layer to be. Depending on the unique specifications of your flooring system and the required load-bearing capacity, typical thicknesses range from 25mm to 75mm.

Once the area and thickness have been calculated, multiply the two numbers to get the needed screed volume, expressed in cubic meters or cubic feet. A small percentage (typically 5–10%) should be added to account for waste, uneven surfaces, or installation-related adjustments. This guarantees that you have adequate screed to finish the task without running out.

Finally, take into account the labor expenses related to the installation. The ultimate cost may vary depending on the site’s accessibility, the intricacy of the floor plan, and the cost of labor in the area. While some contractors charge separately, others may include labor costs in their quote. When getting quotes, make sure to make this clear to prevent any surprises.

In conclusion, being aware of the costs and methods of calculation for half-dry floor screed will enable you, the homeowner or builder, to make wise choices. Through accurate estimation of the required quantity and careful consideration of all relevant cost factors, you can effectively plan your project budget and guarantee a seamless installation process.

Whether you’re a contractor trying to cut costs or a homeowner organizing a renovation, knowing these fundamentals will help you make wise choices and provide a level, smooth floor surface that will last.

What the prices for materials depend on?

The final cost of materials depends on the following factors because the strength, water-cement ratio, aggregate quality, and type of reinforcement of the semi-dry screed can vary:

• Cement brand (binder).
• Amount of cement – the material is one of the most expensive components in the screed, and the strength of the structure depends on it. Increasing the cement in the mixture even by 10% significantly affects the final cost.
• Quality of the filler – sand. For semi-dry screed, medium-sized washed river sand is used, without dust inclusions, which is highly valued in the non-metallic materials market.
• Presence and quantity of fiber. If the screed is not reinforced with a classic metal or fiberglass mesh, Kevlar fibers are added to the mixture, which ensure a reliable connection between the particles.
• Presence of synthetic materials that increase the heat or sound insulation qualities of the subfloor.
• Presence and quantity of reinforcement mesh, as well as its diameter and cell width, which affects the weight and, accordingly, the final price.

A small amount of clean water is also present in the screed, but because of its small volume, its cost is typically ignored.

Equipment costs

Special tools are needed to install a semi-dry screed, enabling complete automation of the procedure. The following units are part of the kit:

1. A compact mixing device or plastering station powered by diesel fuel or electricity.
2. A pump unit can be attached to the mixing device, creating pressure for transporting the finished mixture to the installation horizon (the desired floor). If this electrical equipment is not included in the kit, it is installed and connected separately.
3. A supply hose of a certain length, through which the fiber-reinforced cement-sand semi-dry mixture is delivered to the installation site.
4. A receiving and distribution unit installed on the installation horizon, designed for uniform laying of the mixture on the floor slab.
5. A vibrating screed, if necessary, for uniform distribution of the screed over the area of ​​the room.
6. A paddle smoother is an electrical device designed for compacting and smoothing the finished screed, filling the pores.

All professional installation companies that offer semi-dry stitching installation services have this equipment.

The price of buying or renting these devices on your own is determined by the following variables:

• Brand and country of manufacture of the mixing device.
• Equipment capacity.
• Height of feed of the finished mixture.
• Availability of an automatic module for controlling the amount of ingredients.
• Year of manufacture and degree of wear of the devices.
• Rental duration.
• Purchase terms (cash, leasing, installments).

It is advisable to purchase or rent equipment for the semi-dry screed device and use it independently after finishing an area of at least 1000-1500 m2.

Rental and acquisition costs

If equipment for the screed device needs to be bought or rented, there are numerous options available on the market with the following suggested retail prices:

If you buy:

• Mixing device with a capacity of up to 1.8 m3 per hour, new – from 1-1.2 million rubles.
• The same – up to 3.5-4.0 m 3 per hour – from 3.0-3.5 million rubles.
• Used equipment, depending on the degree of physical wear and tear and age, is sold at a discount of 30% to 70% of the nominal price, subject to its functionality.
• Blade smoother – from 40-60 thousand. rub.
• Hoses with a pressure damper for distributing the mixture along the installation horizon – from 25-35 thousand. rub.

If it’s rented:

1. Up to 5-7 shifts – from 9-11 thousand. rub. per shift.
2. Up to 12-15 shifts – from 8-10 thousand. rub. per shift.
3. Up to 25-30 shifts – 6-9 thousand. rub. per shift.
4. More than 30 shifts – monthly payment, by agreement with the owner.

According to the prices listed above, the customer is provided with a complete set of devices when renting equipment, which includes a blade smoother, mixing unit, pump, hose, and damper.

What affects the price tag for the work on creating mechanized coverage?

Depending on the complexity and volume of work, the customer service department asks for a technical assignment and incoming parameters when contacting an installation company in order to calculate the estimate.

Ultimately, the cost of the service is determined by several significant factors:

1. Characteristics and classes of materials that affect the strength and wear resistance of the subfloor.
2. The thickness of the screed, which determines the number of layers. If the thickness of the structure is more than 70-100 mm, it must be installed in layers.
3. The presence and type of reinforcement of the semi-dry screed.
4. The presence of a heat-insulating or sound-insulating underlay, the need to install the floor using the floating structure method.
5. The area of ​​the room – regardless of the volume of work, equipment delivery and labor costs for commissioning are required. In this regard, installing a floor in large areas is cheaper, based on 1 m 2 .
6. The need to provide related services, or the presence of additional difficulties during installation – underfloor heating pipes, cable channels.
7. Urgency of service provision.
8. Internal policy of the company affecting the price list – the availability of loans, rental space and other factors.

According to the specified criteria, all prices for the half-dry screed device in the rooms are roughly the same due to the intense competition among these services in the market.

Prices for masters" services, if cars are provided by the customer

When a customer contacts a commercial installation company to install a black floor using machinery, they typically offer the following average prices:

• Standard, up to 60 mm, from 500 rubles. for 1 m 2 .
• Increased thickness from 70 to 120 mm – from 800 rubles. for 1 m 2 .
• Insulated with standard thermal insulation of 10-20 mm (total thickness up to 80 mm)-from 650 rubles. for 1 m 2 .
• With an effective insulation (up to 40 mm, total thickness up to 100-120 mm)-from 750 rubles. for 1 m 2 .
• Complex floating floor with vibration and thermal insulation, reinforcement, thickness to 120 mm- from 850-900 rubles. for 1 m 2 .
• Average discount on volume – up to 100 m2 – 0%, up to 200 m2 – from 7% to 10%, up to 1000 m2 – from 12% to 15%, up to 5000 m2 – from 20% to 25%, over 5000 m2 – by agreements.

Depending on the time of year and the quantity of requests from the same customer, certain businesses might provide extra adjustable discounts on promotional days.

How much do services cost if the equipment is from the contractor?

In the event that the facility’s owner has invested in or rented subfloor installation equipment, the installation team’s duties are restricted to laying, per the technological scheme.

In these situations, a minimum of five workers are needed in one link to complete tasks as quickly as possible, under the guidance of a foreman with technical training:

• 1 general worker to fill the receiving hopper of the mixing device.
• 1 operator controlling the unit.
• 1 fitter receiving the mixture through the damper at the mark.
• 2 fitters smoothing the material on the horizontal surface and performing "helicopter" grouting.

Given that the production rate is calculated at a rate of 70-100 m 2 per shift and that the average worker wage varies by region to 2.5 thousand rubles per shift, the cost of the work will be:

• Standard, up to 60 mm, from 100 rubles. per 1 m 2 .
• Increased thickness from 70 to 120 mm – from 150 rubles. per 1 m 2 .
• With insulation and mesh reinforcement – from 200-250 rubles. per 1 m 2 .

The costs differ because the speed at which the completed structure is completed in a shift is reduced when associated operations such as installing mesh, insulation, or sound insulation are involved.

Calculation of the amount of material

In order to determine the material consumption for semi-dry screed installation, the following relationship must be applied in addition to converting the total volume to an area unit.

Let’s examine the computation with a sophisticated floating floor as an example, accounting for vibration damping, reinforcement mesh, and insulation:

1. With a layer thickness cement-sand mortar 60 mm, the volume of the supplied mixture will be 1 m x 1 m x 0.06 m = 0.06 m3 per 1 m2 of floor.
2. The average amount of cement in 1 m 3 of a standard semi-dry screed is 300 kg, or 300 x 0.06 = 18 kg per 1 m 2 . If M400 cement is used, its cost per unit area is 400 rubles. / 50 kg x 21 kg = 144 rubles.
3. Sand for 1 m 3 is required 0.9 m 3 , or 0.054 m 3 per 1 m 2 . With an average cost of material of 650 rubles. per 1 m 3 , the price will be 35 rubles.
4. For each 1 m 3 of a conventional design, up to 800 g of fiber is consumed, or 48-50 g per 1 m 2 . At a price of 400 rubles. per 1 kg, the consumption will be 20 rubles. for each 1 m 2 .
5. Reinforcement mesh with parameters 100 x 100 x 4 mm – 150 rubles. per 1 m 2 .
6. Insulation – extruded polystyrene foam 30 mm thick – 100 rubles. per 1 m 2 .
7. Soundproofing – rolled foamed polystyrene 10 mm thick – 70 rubles. per 1 m 2 .

The average cost of the screed mentioned above, if all materials are bought at retail, will be between 500 and 510 rubles per square meter. Bulk purchases can result in a final cost that is 10%–30% less.

Total installation costs per square meter

In order to determine the total cost of DIY screed installation, you must precisely determine:

• what volume of material will be required;
• the final cost of the material, taking into account discounts;
• the duration of use of leased equipment, or its depreciation in case of purchase.

If an apartment’s floor surface area is 80 m 2 and a screed needs to be installed in a day, the building owner is responsible for covering all costs at the suggested retail price.

The cost per square meter will be 11,000 / 80 = 137.5 rubles if the equipment rental is charged at an hourly rate of 11,000 rubles.

Including all layers, screed installation in a small apartment will cost at least 200 rubles per square meter.

Therefore, the entire cost of installing a semi-dry screed in a small room on your own will be roughly 800-850 rubles per square meter, which is exactly in line with the going rate for expert companies. As a result, doing such work with a small front is not advised.

When considering installer salaries, all work can be lowered to 30–40% if the premises are larger than 1, 2, or 5,000 square meters. This will save money compared to hiring professionals, who will charge 15–25% more.

After accounting for depreciation, servicing, and an average of up to five years of trouble-free operation, the total cost of installing the finished screed is reduced by an additional five to ten percent if you own a mixing machine and other equipment.

The price of installing a half-dry floor screed depends on a number of important factors. The first step is to identify the portion of the floor that needs to be screeded. To find the total square meters, multiply the length and width measured in meters. Next, determine the required screed depth, which is usually between 30 and 40 mm. Then, multiply this depth by the area to convert it to cubic meters.

You can estimate the cost of materials once you know the total cubic meters that are needed. Typically, half-dry screed is made of cement, water, and sand. The price will be determined by local rates for these materials, which can differ significantly. Moreover, take into account any reinforcement materials or additives that might be required based on the particular needs of your project.

Labor expenses are yet another important factor. This will depend on the intricacy of the project, site accessibility, and local labor costs. Obtaining quotes from multiple contractors is a good idea if you want to compare costs and make sure you’re getting a fair price.

Additionally, take into account extra expenses like hiring equipment if specific tools are required for laying and mixing the screed. To prevent unpleasant surprises, you should factor in delivery costs for materials when creating your budget.

Finally, remember to budget for unforeseen events. Unexpected elements can affect timeliness and cost, such as uneven surfaces or unanticipated delays. Including a buffer in your schedule and budget can help reduce these risks.

You can determine a reasonable estimate for the cost of setting up a half-dry floor screed by following these steps and taking into account all pertinent factors. Your project will proceed smoothly and stay within budget if you plan it out properly and estimate costs thoroughly.
