Macroflex cement foam is designed to bond various surfaces. The material developed using polyurethane allows fixing construction and finishing materials among themselves, eliminating gaps in the seams, its use makes it possible to increase the heat and sound insulation of the main structures. Features of the chemical composition of cement foam allow you to work at temperatures in the range of 5-35 ° C.
The main purpose of Makroflex cement foam is to replace the usual cement-sand mortar used in the construction of internal partitions and other non-bearing walls made of gas silicate blocks and lightweight concrete products. The rejection of dusty (during preparation) and heavy mortar can significantly increase the speed of erection of structures, and the technical characteristics of foam cement in cylinders are not much inferior to traditional building mixtures.
It is believed that a standard aerosol can of liquid material with a volume of 850 ml allows you to replace a 25 kg bag of cement grade M400. In this case, the master will not have to spend time and energy on preparing the solution and transporting it to the construction site, which significantly reduces labor costs in the construction and finishing works.
Specifications
For specific construction and finishing works, various types of Macroflex foam cement are used. The scope depends on the temperature and humidity conditions at the facility and the characteristics of the materials that need to be linked together.
The general technical characteristics of all products include the following properties:
- density - 20 kg / m3;
- the time required for the formation of surface tension is 5-9 minutes;
- the time required to obtain the estimated strength values is from 25 to 30 minutes;
- water absorption during the day - within 1%, the maximum value - not more than 10% during the month;
- sound protection - within 60 dB;
- thermal protection - up to 0.4 W / mkhK;
- fluctuations in the volume of the foam - up to 5%.
After gaining strength, this material is able to maintain design properties at outdoor temperatures from -40 ° C to + 90 ° C. Short-term temperature jumps up to over 100 ° C are permissible.
The description of this material indicates that propellants containing fluorine and chlorine compounds are not used in the solution. Fresh foam emits a slight smell, and when the mounting mixture dries, the smell disappears altogether.
Kinds
The manufacturer produces several options for Macroflex foam cement. The use of specific material depends on the tasks to be solved. The main products of this brand include the following products:
- Makroflex Shaketec - the technical characteristics of this product allow its use at any time of the year.
- Makroflex Winter - characterized by the ability to maintain installation characteristics at low temperatures. This foam is designed to work in the cold season. It provides increased sound insulation of structures and is most often used for installing window and door blocks.
- Makroflex Premium - provides a double volume increase, each cylinder is equipped with a special device for spraying foam.
- Makroflex Premium Mega - allows you to accurately calculate the dose of application of the material and allows you to install building foam blocks at low temperatures in winter conditions. Provides a strong connection of materials up to -15 ° C.
- Makroflex Pro is a professional version of foam cement. Application - at construction sites for bonding solid materials in critical structures. It has strong adhesion with various bases.
- Makroflex Whiteteq - differs from other types of aerosol products for bonding surfaces with increased resistance to ultraviolet radiation, while maintaining strength properties. Inside each can there is a metal ball, which allows you to mix the solution well before use.
Each of the listed types of cement foam allows you to save workers from the hard work of preparing a cement-sand mortar. Using a particular type makes it possible to carry out installation work in any conditions and with any material with consistently high quality.
Scope of application
Macroflex cement foam is convenient for use in construction and finishing works, but it is not used for the construction of capital and load-bearing walls. Responsible structures are best built using traditional mortars. New material is recommended for the following work:
- for mounting internal partitions;
- for repairing masonry from aerated concrete, brick or foam concrete;
- to perform insulation of external walls using heat-insulating mats;
- to perform repair of building structures;
- to eliminate gaps in filling joints and joints of panels and other structures;
- for installation of window and door blocks, window sills and steps on the interfloor stairs in private houses;
- for waterproofing joints in concrete structures.
One aerosol can of this material is enough for the installation of cladding panels on an area of up to 12 sq.m., the same expense is provided for the construction of a brick wall, 250 mm thick per 10 sq.m.
Pros and cons
Before starting construction work with the use of new material, it is necessary to find out what advantages and disadvantages of cement foam can affect the quality of work.
The positive aspects include:
- convenience of storage, carrying and use;
- cost comparable to the price of familiar materials;
- the ability of the material to bond surfaces with various characteristics;
- instant setting of material;
- the ability to work at low and high temperatures;
- the use of cement foam does not imply a mass of waste and dust, which reduces the time for cleaning the room;
- foam-cement is an effective means of sound and heat insulation;
- the durability of the material allows it to be used for most critical structures.
The disadvantages of foam-cement include the following points:
- this material has little resistance to the effects of UV rays - when they get on the foam-cement, a loss of strength characteristics and gradual destruction occurs;
- when working with foam, it is necessary to use personal protective equipment for the respiratory tract and organs of vision.
Application Tips
When carrying out installation work using Macroflex foam cement, the following tips should be taken into account:
- for better adhesion it is necessary to remove dust and fines from the working surface;
- if necessary, degrease the surface;
- before starting work in the cold season, it is recommended that the cylinders be kept in a warm room for at least half a day;
- periodically, the aerosol container with the material must be shaken vigorously;
- for the installation of structural elements, a step between the foam-cement strips of 15 cm is used, the indent from the edge of the element should be at least 5 cm;
- to obtain an even and equal thickness strip of foam, it is recommended to use a mounting gun;
- the gun is cleaned of material residues by a special composition;
- for better adhesion of the foam to the surface of the structural element, after cleaning from dust, it is recommended to moisten it;
- seals and joints are sealed from bottom to top.
