Consumption of sealant per meter

Consumption of sealant per meter Consumption of sealant per linear meter - calculator and methods of manual calculation

When planning repairs, as well as construction work, making the correct calculations of the required materials can not always be easy. But in the case of putty, it is better to know in advance the exact consumption of the sealant per running meter, so that it does not accidentally end at the most inopportune moment.

If just such a variety was selected, which is made to order, and then a new batch will have to wait a very long time, suspending repair work.

Consumption of the polyurethane-type composition per 1 meter of the seam is calculated taking into account its width, length and depth using special formulas.

Features and characteristics of sealants

By means of a silicone or polyurethane compound, it seals various joints and seams, as well as other required areas inside and outside the room.

Silicone formulations have the following properties:

  • Consumption of sealant per meter Resistant to ultraviolet radiation.
  • Resistance to negative environmental factors.
  • Excellent adhesion to all types of surfaces.
  • Resistance to temperature changes -50 ..

    . + 210 degrees.

  • Possibility of application at an operating temperature of -31 ...

    + 61 degrees.

The main couple of factors on which the sealant consumption will depend are the depth and thickness of the slots. Silicone sealant is highly elastic, has an average degree of elongation, and this can be determined by the level of interaction with a certain type of surface. In order to increase elasticity, this sealant must adhere exclusively to two seam sides. If the adhesion occurs to the rear surface, then there is a high probability of mechanical breakthrough, in the event of material deformation.

In order to exclude such a possibility, a special sealing cord is used, which will act as the basis for laying the substance. Most often, sealants can be found on sale in special cartridges with a standard volume of 0.31 liters, and also a file-package of 0.3 and 0.6 liters.

Sealants are substances that cannot be stained. For this reason, you should immediately choose a composition that suits the shade or choose a transparent variety.

Calculation of the consumption of funds

Quite often due to incorrect certain sizes of the joint, as well as the lack of experience in applying a polyurethane-type composition, there is even an overspending of the substance. At the same time, the increased level of consumption of the sealing agent will not be the only drawback due to ignorance of the technology. If the seam itself is filled with sealant incorrectly, then its operational life will be significantly reduced.

First of all, it is imperative to evaluate the depth and width of the joint in order to determine the consumption of the sealing compound.In bathrooms, as well as sanitary facilities, suitable indicators for sealing the gaps between walls and metal / acrylic bathtubs, and also a tiled covering on the wall will be a seam 0.6 cm wide and 0.3 cm deep.

If these parameters are observed, then the consumption of silicone-type sealant per 1 meter of joint will be 20 ml.

Most often, sealants are sold in standard packages with a volume of 0.31 liters. To understand the optimal consumption of a conventional pack of silicone sealant in order to fill oblique seams, corner joints of walls. Here you can use the data in the table.

Width in cm 0.


1 1. 5 2
Depth in cm 0. 4 0.7 1 1. 4
Seam length in meters 11.


4. 2 1. 9 1

When filling standard semicircular-type joints with polyurethane sealant, the consumption of sealant per joint will be much less, since it will differ in the classic proportions of the ratio of depth and widths, as 1 to 2. Other key figures for standard packing of sealant are described in the table.

1 1. 5 2
Depth in cm 0. 3 0. 5 1 1
Seam length in meters 16. 2 5.


2. 6 1. 5

In order for the seam to be filled correctly, neatly and evenly, cut the spout on the sealant tube according to the instructions, use a spatula with an edge of 0.6 cm. Cutting should be done very simply - it is required to knead the edge of the spatula tool at an angle of 45 degrees in relation to the nose.

Using a construction knife, cut the plastic above the area where the rib will be the same size as the spout. To make accurate calculations for the consumption of sealant, you can use a special online substance cost calculator. All basic data should be entered into the system (we are talking about the depth and width of the seam), and the result will be issued automatically.

To determine the consumption of silicone sealant, you need to use a simple set of convenient formulas, one of them makes it possible to determine the required volume of sealant and the many substances required to treat all seams and surfaces:

  • Consumption of sealant per meter The volume of the sealant V is equal to the joint length times the thickness and height.
  • Sealant weight will be defined as the product of the resulting sealant volume R and V, with R being the sealant density and the average value being 1.

    5 tonnes per cubic meter.

It is enough to make calculations according to the formula for one running meter of the seam. After determining the value, it should be multiplied by the entire length required for sealing. To calculate this value, it is enough to use a simple tape measure.

Average consumption

Consumption of means for embedding, fastening, sealing joints will largely depend on the base material with which work is required.

Depending on the type of materials, you can find out about the standard size that will be laid during construction and installation work. On average, this is 0. 6 cm.

In certain cases, it is required to determine this value individually. If the joints will have large parameters, for example, width and depth, then use a special silicone cord for work, which will act as a sealant.

Its use will be especially relevant when working with wood bases. The average calculation of the consumption of a substance makes it possible to determine the suitable containers in which it will be sold.

To avoid unnecessary consumption, for example, if the width and depth of the opening is 0.5 cm, and the length is about 10 meters, and then 0.25 kg of sealant is required.

For this reason, you can safely buy a bedside table with a consumption of 0.3 kg, leaving a little substance in reserve.

It is important when carrying out work after the average calculation of the consumption of the sealing agent should be observed when applying the agent. For this reason, the surface should be prepared in advance, cleaned of residues of dust, debris and other substances, and also degreased. Both sides of the surfaces that are adjacent to the seam should be covered with masking tape to prevent the sealant from getting on them.

After that, the cut should be made correctly on the tube with the sealant, and after preliminary placement in the assembly gun. If all the preparation work and flow calculations are performed correctly, then the substances will ideally lie flat in the cracks and level with a spatula. It does not matter whether repair or sealing work is carried out inside or outside, choosing a silicone sealant for an outdoor type of work or for solving household problems. It is very important to spend a little time on a preliminary calculation of the composition consumption, to get acquainted with the correct technology. So all the masters will not only be able to avoid overspending of the substance, but also save money, and also carry out work on filling the joints as efficiently and quickly as possible.
