The consumption of the sealant of polyurethane per 1 m seam: a table with an example of calculating the required amount of sealant according to the formula

For sealing joints and seams in building and remodeling projects, polyurethane sealant is an adaptable and long-lasting option. Polyurethane sealants are great for a variety of applications because of their excellent adherence and flexibility, whether you’re working to seal gaps in concrete, wood, or metal. However, estimating the amount of sealant required for a project can be challenging, particularly if accuracy and economy are your goals.

It’s crucial to compute the consumption based on the precise dimensions of your seams or joints in order to get the appropriate amount of polyurethane sealant. This guarantees that you won’t waste too much or run out of material before finishing your project. Using a straightforward formula and an easy-to-read table, our guide offers a straightforward method to help you accurately estimate your sealant requirements per meter of seam.

We’ll take you step-by-step through the polyurethane sealant consumption calculation process in this article. We will provide you with a handy table that illustrates typical calculations for different seam sizes, and you will learn how to apply the formula to the dimensions of your own projects. By the time it’s all over, you’ll know exactly how much sealant to buy and how to measure it, which will make sealing jobs easier and less expensive.

Properties of polyurethane sealant

The following characteristics of polyurethane (silicone) sealant contribute to its popularity:

The sealant is polyurethane

  1. Not exposed to ultraviolet radiation;
  2. Inerten to aggressive environments;
  3. Excellent sticking to any surfaces;
  4. Withstands the temperature difference of 250 degrees;
  5. Excellent sealing and waterproofing;
  6. Does not spread on the surface;
  7. The possibility of applying, both at negative temperatures and at large values ​​of a positive range;
  8. Environmentally friendly;
  9. The service life exceeds 10 years, subject to the technology of application.

It’s important to know how much sealant you’ll need when using polyurethane to seal a seam in order to prevent waste and underabundance. To find the precise amount of polyurethane sealant needed per meter of seam, this article offers a simple table and calculation method. You can quickly estimate how much sealant will be needed for your project by knowing the dimensions of your seam and using a straightforward formula, ensuring an efficient and effective application.

Types of polyurethane sealants

Acetate and neutral silicone sealants are the two varieties available. Glass and other smooth materials work well with acetate. Acid is a component of the composition, so metal cannot be used. It is possible to use acetate glue in well-ventilated spaces.

  • The neutral composition can be used on any porous planes. It has good adhesion and is not subject to temperature differences.
  • Silicone sealant with fungicide is designed for use in wet rooms. A substance that is part of the glue does not allow the occurrence of the fungus.

The size of the seam is the primary factor that determines how much silicone is used. A special cord, a seal, is laid in a large seam to make it smaller. Logs are frequently compacted using it.

Since polyurethane sealant doesn’t react with any kind of paint, painting over it can be challenging. Since different shades of substances are sold, you should consider color beforehand.

There are two types of polyurethane sealants: one component and two component. Two components must be manually mixed into the composition; one component is provided ready for use.

Formula for calculating the sealant for 1m

Use the formula for calculating the volume of a rectangular parallelepiped (volume = length × width × depth) to determine the required amount of material. The result for a triangular seam needs to be split in half. The quantity of glue needed could be enormous if the crack needs to be filled.

The manufacturer always states that the amount of silicone in each package is known, and figuring out how many packages there are is simple. There are two volumes that produce cartridges: 310 ml and 600 ml. For instance, 20 ml of a substance (1 liter = 1000 ml) will be required to seam a bathroom per linear meter with a width of 6 mm and a depth of 3 mm.

Calculators for figuring out how much material is needed for a repair can be found online.

To determine how much silicone is needed to seal a log house’s sutures, you need:

The sealant is polyurethane

  • Calculate (l) the consumption of glue by one linear meter and multiply by the amount of meters;
  • Determine (w) the distance between the crowns, on average, is 5 – 7 mm;
  • Height H is taken equal to 1/10 of the thickness of the log: measure the log diameter, divide by 10 and round the smaller way. The calculation formula has the form: m = l*h*w*r.

Using a sealant for a roof

The same calculation formula is applied, but because of the harsh working conditions on the roof, the masters recommend adding 30%. It is preferable to hire professionals to apply silicone to the roof, as this will positively impact energy savings.

Seam Width (mm) Sealant Consumption (ml)
5 12
10 25
15 37
20 50

It is crucial to comprehend how much polyurethane sealant is used per meter of seam in order to achieve cost-effective and efficient sealing. The formula provided will help you determine how much sealant is required for your project. This guarantees that you stay clear of shortages and needless overbuying, both of which can result in waste and higher expenses.

Our sample calculation shows how easy it is to figure out how much sealant to use. To obtain an accurate estimate, you can use the formula if you know the seam’s width and depth. This method reduces the environmental impact of excess materials and helps with budgeting in addition to simplifying the planning process.

This article’s table, which provides estimated values for various seam sizes, is a useful resource. This eliminates the need to constantly recalculate and makes it simple to evaluate your requirements quickly. You can save time and make sure you have the proper amount of sealant for every job by keeping this table close at hand.

Professional results can be attained by precisely measuring and calculating the amount of sealant required. Whether you’re working on a small home improvement project or a large construction project, following these guidelines will help you finish your work quickly and effectively.
