The plasticizer for screed floor heating

The plasticizer for screed floor heating

plasticizer is a reinforcing additive for pouring the floor, which increases the level of plasticity and spreadability of the building material mixture, increases its density and uniformity.

plasticizer for underfloor heating simplifies the process of alignment allows you to make the surface smoother and more aesthetically appealing.

main function of this component is to improve the solubility of the cement clinker and enhancing interaction with cement particles.During

chemical reaction these particles in different directions reduces the number of air pores is reduced percentage of water, and the mixture is plasticized.

advantages and properties of the plasticizer

plasticizer for floor screed is the basis for multi-functional compositions and dry mixes used in construction.


It is added to mortars and concretes, including cellular, having high performance.

plasticizer for screed floor heating has the following useful properties:

  • performs the function inhibitor that slows the corrosion process, provoked by a high concentration of chlorine;
  • allows to obtain high-density, water-tight concrete;
  • adding provides exceptionally low doses increase in strength, without affecting the other characteristics of the final product, in particular - the porosity and permeability;
  • acts as antifreeze admixture, providing protection at temperatures up to -25 ° C;
  • concrete in the presence of a mixture of potassium nitrate plasticizer acts as a catalyst it, preventing its formation;
  • Portland accelerates the setting process, containing a small amount of soluble alkalis.

must be remembered that the plasticizer for screed floor heating is an incredibly complex chemical composition a substance which may have a different behavior in different conditions.

When using it, it is extremely important to adhere to instructions and added to a solution of the amount of the plasticizer, which it states.

Effect of plasticizer on the concrete:

  • reduces the setting time after the completion of the work, especially when leveling plates for floor or domestication of ready-made elements;
  • reduces the pressure in the case of subsequent batches of the solution;
  • ensures rapid solidification of solutions with a high percentage of water content;
  • during long transports the liquid cement composition in which the plasticizer has a solution may be activated by adding thereto the potassium nitrate;
  • using the cold prevents premature hardening due to significant heat generation due to the hydration process;
  • provides a self-sealing hydraulic concrete with high strength properties.

plasticizer increases the strength of the product compression and accelerates the formation of this strength, so that demolding of concrete products can be carried out within twelve hours without fear of chipping and other defects.

In some cases, the use of cement is permissible even lower marks.

Essentials application plasticizers for underfloor

industry today made several types of additives that improve the characteristics of a concrete solution: liquid and dry plasticisers, reinforcing polyamide fiber, anti-freeze.

They accelerate the solidification process solution, increase flexibility, and antifreeze additive allows you to work with concrete, even in conditions of negative temperatures.

When the equipment of water underfloor heating is used plasticizer, preventing the formation of voids in the concrete mass.


Due to the fact that the solution is poured directly on the pipe, it is extremely important that the screed has been able to withstand heavy loads, avoiding mechanical damage to the pipeline.Therefore

layer of concrete over the pipes must have a minimum thickness of 25 mm.

plasticizer for warm water floor in this case gives a greater elasticity solution that simplifies the process of surface smoothing.

When installing electric systems for floor heating requirements for the strength characteristics of the screed is not so tight, though, it must also have a high degree of safety to avoid damage to the heating system.

plasticizer for underfloor heating increases the strength of the finished floor, prevents deformation after drying.

Highlights application plasticizer:

  1. The concrete mix for the concrete plasticizer for underfloor heating is introduced simultaneously with the other ingredients: cement, aggregates and water;
  2. Thereafter the thorough mixing of all ingredients in the mixer for about one and a half hours, until the grout reaches the consistency of a homogeneous suspension;
  3. The resulting mixture can be used to fill the floors in private homes, industrial premises, other buildings and structures.At the same time in order to achieve high quality of the finished work is necessary to follow the uniform distribution on the surface of the base solution;
  4. One of the basic conditions that ensure the reliability and durability of the floor, - to give them a good freeze before using.So, a week after pouring the floor is already possible to go through two - install furniture and miscellaneous equipment.Fully process of drying and hardening of the floor ends a month after it fills.

Where to buy and what price?

Buy plasticizer for underfloor heating you can on the Internet or in specialized hardware store in your city.

Also this construction supplement sold in the construction markets.If you are interested in price, the plasticizer for underfloor heating can cost from 50 to 150 rubles per kg.

1 kg of mixture you may need from 2 to 10 g of this component, depending on the manufacturer and the quality of the plasticizer.

consumption and production ArmMiks Thermoplastic Sanpol is 2 g per 1 kg of the mixture, and the cost - 100-120 rubles.per kg.

Rehau The plasticizer is used in an amount of 10 g per kg of the mixture, and the cost is similar to the previous product manufacturers.

When selecting Always consider the scope of work and type of mixture in which the plasticizer is added.
