The advantages of macrophlexes

The manufacturer makes a polyurethane sealant called Makroflex in tubes with different capacities, but the majority of chassis are thought to be foam in 750 mm cylinders. The preformer and gas in the component composition force the material out of the tube, increasing the volume and speeding up the hardening of the mounting foam. Owing to its excellent insulating properties, polyurethane compositions are widely utilized.

  • Expressed adhesive properties.
  • Uniform filling of cavities.
  • High strength, durability.
  • Lack of toxins, fire resistance.
  • Good insulation characteristics.


Mounting sealants became widely available with the founding of Makroflex, which is now a part of the renowned Henkel holding (Estonia). Pens, adhesives, cleansers, and other items for construction and installation are produced by the company.

The installation sealant line Because Macroflex is reasonably priced, both professional builders and general consumers use the foam provided by the manufacturer. When using polyurethane material, it is important to consider the technical specifications of the Makroflex mounting foam, as the 750 ml cylinder will result in a 100% increase in the hermetic mass volume.

Advantages and disadvantages

The primary benefit of the sealant is that it eliminates the need to mix components and saves time during product preparation because the mounting composition is instantly usable. The principal benefits of polyurethane material are:

  1. Universal application for different surfaces and climatic conditions.
  2. Simplicity and ease of use – mounting foam is placed in a tube, for spraying they use a pipe or gun.
  3. The full polymerization of the composition occurs within a day, and the initial hardening occurs in a few hours.
  4. Extensive temperature range, there are special sealants for winter use.
  5. Foam has good insulating properties, dust formation is excluded during operation.

The mounting composition’s vulnerability to UV radiation is a drawback of the products. Cement, gypsum, or a composition based on water is applied over the sealant to prevent the mass from disintegrating over time. It is necessary to wear personal protective equipment when spraying foam to prevent skin, hair, and eyes from being exposed to the polyurethane mixture. Gun use is convenient for uniform mass distribution on the surface to be used.

Pros and cons of the Makroflex installation foam are discussed in the video.


Makroflex manufactures sealants with various technical attributes. They ascertain the mounting foam’s sphere and usage guidelines. The assortment of the Estonian manufacturer’s products, which come in multiple composition types, is supplied to the global market.

  • Professional remedy Makroflex Premium on a polyurethane basis. The foam is implemented in cylinders of 750 ml, it is well adopted with surfaces.

  • Winter winter foam has an important advantage -a sealant of Makroflex Shaketec can be applied in a temperature range from -10 to +25 degrees when installing roofs, windows, doors.

  • The PEMIUM MeGA series series belongs to the category of professional installation sealants specially designed for use at a negative temperature.
  • Material material of foaming Makroflex Pro can increase in volume to 65 liters, is well suited to fill large voids and cavities, when the rooms are insulated.
  • The manufacturer produces an innovative product of Whiteteq, the main advantage of which is the effective resistance of the composition of ultraviolet rays due to the microporous structure of QUATTRO.
  • The Macroflex mounting “foam -cement” is used to quickly connect the block and panel elements, except foam concrete products, as well as steps, window sills.

The macrophlex should consider the purpose for which the sealant is required before purchasing the mounting foam. To seal small seams and joints, it makes no sense to use professional foam 750 ml; instead, use a universal sealant. Funds, excluding substrate breaks, have a high coefficient of foaming and shrinkage of no more than 5%. Compared to professional installation substrates, household use (semi-professional with a pipe) is orders of magnitude less expensive.

Keep in mind to select a sealant based on the season. Macroflex’s assortment offers compositions that are suitable for low, high, and normal temperatures, as well as summer and winter variations. The product hardens more quickly in higher ambient temperatures.


You must base your mounting sealant consumption calculation on the dimensions, area, and form of the processed surface. Determine the width and depth of the docking seam in order to fill the spaces in a rectangular, square cross section. The outcome will be expressed in milliliters of foam per square meter.

A simple example of calculation: if the cavity filled with sealant has a depth of 40 mm, a width of 10 mm, then 40×10 = 400 (ml) foam per seam meter. From one cymetics cymetics with a volume of 750 ml, it will be 100% more than the foam composition at the output. The manufacturer indicates on the packaging the average sealant consumption and the release of the substance, but the size and shape of the filled seam is affected by the final calculations. Experts calculated that when using the “foam cement” on 10 squares of brickwork in 1 brick, 850 ml of sealant will be required. The output of the mounting foam (volume) indicated by the manufacturer is obtained when performing work at optimal humidity and temperature. It should be borne in mind that sealants are expanded twice – at the exit from the tube and in the process of polymerization of the foam mass. When filling the cracks, joints and seams, you need to leave the third part of the space with incomplete.

Drying time

The environment’s temperature and humidity, the material’s component makeup, and the proper application technique all affect how quickly Makroflex mounting foam hardens and fully polymerizes. The ideal temperature for sealing is +20 °C. In this instance, the foam will start to solidify in two to three hours, but it will take at least twelve hours for the composition to fully polymerize.

The sealant cannot "gain" its full volume due to the low ambient temperature, and the composition takes a day to fully dry. When executing certain pieces, the masters must allow their hands more time to dry. The foam can be painted, puttied, and cut during the first two to three hours while the product hardens. You can speed up hardening by moistening a mass of hermetic material.

Foam macrophlexes mounted on mounting surfaces provide an adaptable option for a range of DIY and construction tasks. They offer dependable support and insulation because of their expanding qualities and strong adhesive. Mounting foam macrophlexes are useful for insulating spaces, sealing gaps, and fastening objects.

The simplicity of mounting foam macrophlexes is one of its main benefits. Just place the foam where you want it, and it will expand to fill in spaces and stick to surfaces. Because of their simplicity, they don’t require specialized knowledge or equipment, making them suitable for both professionals and do-it-yourselfers.

Additionally, mounting foam macrophlexes stick very well to a variety of surfaces, such as concrete, metal, plastic, and wood. Their adaptability renders them appropriate for an array of uses, ranging from reinforcing window frames to caulking wall fissures. Their capacity to adapt to a variety of shapes guarantees a strong and secure bond.

Furthermore, installing foam macrophlexes improves a building’s comfort and energy efficiency by offering thermal and acoustic insulation. They help create a more sustainable environment and lower energy costs by sealing gaps and stopping air leaks. Quieter interior spaces are produced by the additional insulation’s ability to lessen noise transmission.

To sum up, mounting foam macrophlexes provide a useful and efficient way to fix, seal, and insulate applications. They are an essential component of building and remodeling projects because of their robust adhesion, insulation qualities, and ease of use. Mounting foam macrophlexes are a useful addition to any toolkit, whether you’re working on small repairs or large-scale installations.
