A foamed substance with a homogeneous, uniform structure of tiny air cells is called foamyplex. There are only two varieties of this material available to buyers: 35 and 45 kg/m³.

They vary in a wide range of traits, attributes, technological capabilities, and purposes:

  • Foamyplex with a density of 35 kg/m³ is used for industrial purposes, can provide thermal insulation in residential premises.
  • Foamplex with a density of 45 kg/m³ is used in the construction of highways, the design of oil and gas pipelines, as well as railway construction.

Less important applications for the material include internal wall, ceiling, facade, foundation, and room insulation.

The following technical attributes apply to Foamyplex:

  • Increased strength.
  • Moisture resistance.
  • Low thermal conductivity.
  • Resistance to mechanical influences.
  • Simplicity of installation.
  • Reduced chemical activity.
  • Resistance to fire.
  • Environmental purity.
  • Long service life.

On specialist tile glue, foaming is applied. The longevity of the material and the well-being of those who reside in the home or frequently use the room can both be prolonged by selecting the appropriate adhesive mixture.

Types of adhesive compounds

Generally speaking, all materials found in building supply stores that are meant to glue foam with different grounds have a high degree of adhesion, offer a good coupling for many years, and improve the finish’s quality. Every adhesive compound manufacturer makes an effort to list the key technical specifications for the product’s operation on the packaging. Suitable surface types, ideal air humidity, and the acceptable temperature range for application and subsequent use are a few of them.

It is worthwhile to give careful thought to every kind of available assortment and determine which glue is most suitable for your needs.

Bitumen mastic

The bitumen mastic maintains its properties in the frost and has a thick consistency. In construction, bitumen-based materials are frequently utilized to waterproof the foundation. You can either fill the spaces between the glued foamyx or glue on the mixture in accordance with the intended use. He will function admirably as a hydrophobic filler in this instance.

Using a maclovor or spatula to glue the plates together with such a thick mixture will be convenient.

It’s critical to understand! Mastic gives a material with a base of metal or minerals a high degree of adhesion. The substance does not need to shrink in this instance.

Liquid Nails

Since this adhesive mixture can adhere to any base, it can be referred to as universal. Nonetheless, the location of the surface—whether it be externally outside or inside—must be considered. Standard compounds work well for interior work, but you need to use specialty products that can tolerate temperature fluctuations and have good frost resistance for insulation on the street.

It sells comfortable tubes of liquid nails. You must use glue across the entire surface of the stoves in order to provide a good coupling. Ten to twenty seconds is the grasp time. However, liquid nails are a more expensive material than other substances.


If you do not know how to glue the foam to concrete, pay attention to the mineral compositions. They are sold in the form of dry powder, which must be diluted with water, observing the proportions, to the necessary consistency. They differ in a high degree of adhesion and allow you to work not only with concrete, but also with gas silicate, brick. Mineral glue has high plasticity, economical in consumption. To glue with high quality, it is enough to apply a thin layer. For application you will need a gear grater. Does not shrink after drying, remains in the initial volume. Mineral glue for a foam for external work is moisture and frost resistant.


Typically, polyurethane adhesive is found in handy metal cylinders that are easy to work with a construction pistol. It enables the application of dosed glue in a level layer on foam. Laying it out in zigzags will ensure that the area grabs uniformly. The foam’s polyurethane adhesive can be grasped in less than 30 seconds and offers a firm closure, but it soon loses its elasticity and solidifies completely in 15 minutes.
