The floor is a conglomerate layers must work together as one. The installation, is the last operation of a whole string. Flooring can be installed by gluing two distinct situations, leveling screed directly if it is flat and appropriate benchmarks or leveling screed applied over that extra level to correct differences and leveling compound. Strengthening and consolidation of the screed and achieve vapor barrier (waterproofing), in both cases, is done with different types of resins or primers collectively.

The substrate is represented by a rough concrete floor leveling, which can be cement-based or calcium sulphate (gypsum). When these hoes incorporates heating system, represented by pipes through which heat is called and underfloor heating.
Sometimes, putting in work quality and execution of leveling screed (benchmarks, surface smoothness, compactness, no cracks, etc..), Make it impossible to mount direct prosecution as rough concrete floor has excellent mechanical resistance to compression and to tearing, poor. In many cases, rough concrete floor and high humidity can have its mass, will transmit moisture or floor leveling compound, resulting in damage to the wood floor. Remedy the deficiencies listed above, are corrected by the use of chemicals, resins collectively. Depending on the chemical nature, resins come in many ways and can be used in various ways. Just knowing the properties of these materials, we can use them correctly!
Mechanical characteristics, A coarse leveling screeds based on cement that will apply a leveling compound or solid wood that will be installed with glue applied, are: to be dry, wet CM 2%, measured with carbide hygrometer throughout its thickness, with a compressive strength of 25-30 N / mm, with a measured minimum pull off strength of 1.2 N / mm, without cracks or crevices, and the hammering of sounding full!
Before applying primer or resin, regardless of the screed, the first operation is polishing the surface, to open the pores, followed by extraction and dust removal.
This leads to a thorny problem and of great flooring for many who want to perform this type of work ... choice of primers and resins. To see which groups and what options we have regarding the choice of resin from Mapei.

It is an acrylic resin aqueous dispersion, ready to use. It should be noted that there are several types of acrylic resins, with different formulas and properties. Generally use acrylic primer before pouring a concrete floor leveling compound applied bonding distance themselves or floating, or on a concrete slab, dry, wet CM 2%. The substrate must be absorbent, rough, prepared by sandblasting, milling and roughening. A compact and less absorbent support should be especially rough, prepared by grinding and roughening! The acrylic primers are not used if the floor will stick directly on rough concrete floor! To penetrate the acrylic resin support is diluted with water in ratio of 1:2 - 1:4. Classical acrylic primer used to work on leveling with leveling compound for leveling screeds based on cement or calcium sulphate (gypsum), including heated floors. After application and drying is very low emission of volatile organic compounds (VOC) and is not dangerous for the applicant or partner. This product is printed on the packaging and marking data sheet with EMICODE GEV / EC 1.
Economic: is considered the most accessible primer. Consumption, undiluted primer is about. 0.1 to 0.20 kg / sqm. The material is ready. The remaining material can be used for other works.
Technical: use acrylic primer is often limited because it consolidates support and does not create a moisture barrier.

Obs. Acrylic primer is intended to set very fine dust suction and left behind, especially, to equalize and reduce water absorption of the substrate, which should not absorb water preparation of composition leveling compound! Not must to form a primer layer or film substrate surface. Now leveling / substrate is very good and is done because roughness screed that is "caught" leveling compound. Acrylic primer serves no building / strengthening, waterproofing / vapor barrier and pouring leveling compound can be a few hours of drying primer.

Products are formed from two components, Comp. A, epoxy resin and Comp. B, the hardener. Reinforcement is only possible after mixing and homogenizing components by chemical reaction. This class of materials is divided into two groups, resins, solvent and solvent-free resin!
Epoxy resin is the type of product used to treat screed to floor installation works.
Before applying resin to be polished to a rough concrete floor was open pores. The resin is applied on cement screeds or calcium sulphate (gypsum), including heated floors. It is a versatile product.
- Can act as a Primer (Fixing the Dust), if installed directly over the resin flooring, maximum 24-36 hours after application and in this case will be used only reactive epoxy-polyurethane adhesives!
Attention! Use epoxy to floors heating system can be built only for your building / strengthening. These floors can not waterproofing (vapor barrier resin do not realize).
Can act as an anchor and vapor barrier. For use and the role of bonding, The last layer of resin spread good fresh, in excess, dry sand, 0.7 to 1.2 mm apron, obtaining a rough surface that safely apply leveling compound.
Obs. Epoxy resin is relatively high cost per square meter, but solves many technical issues in the future could damage wood floors. Once applied, absorbed in the substrate and hardened, epoxy should form a thin layer to the substrate surface, the effect of strengthening, waterproofing and vapor barrier so. By impregnating the structure screed, resin acts as an additional binder substantially increases the resistance to abrasion and plucking.
Humidity can support max. 5%, measured CM to epoxy resin.
Epoxy resin screed acts on the material: primer / fix traces of dust remaining after extraction, building / strengthening, waterproofing / vapor barrier, impregnation / consolidation and anti-dust system.
Epoxy product consumption is variable / sqm, according to the state bonding mechanical screed, should perform additional maneuvers as it applied in two layers, and the last spread quartz sand, and another sand extraction operation, and require the usage applicator mixture prepared in a relatively short time (~ 40-50 minutes).
* If the epoxy is applied correctly, in two layers and spread the last layer of quartz sand, after hardening resin and sand extraction in excess, will result in a highly rough surface that is ideal for casting compound. Now leveling / substrate is very good and is made of resin due to roughness layer of quartz sand.
If you dig ** rough is smooth and straight and the epoxy resin layer is no longer spread quartz sand, it is possible to mount directly to floor, while the 24-36 hours from the resin using epoxy bicomponent polyurethane reactive adhesives!

| *** If the resin layer spread from 0.1 to 0.3 mm quartz is possible to mount directly to floor, in a few weeks from the resin using reagent-component polyurethane adhesives, epoxy bicomponent component polyurethane or silane. |
The main types of epoxy trowel fall as follows:
|
Two component solvent free epoxy resin
Mixture components, after curing, the resin is 100% pure, is very fluid and therefore should not be diluted because it has a good penetration capacity in support. The application and it dries to a very low emission levels of volatile organic compounds (VOC) and is not dangerous for the applicant or partner.

It is a relatively new product, especially the Romanian market. There are many followers of this innovative product, but as assemblers discover features and advantages of solvent-free polyurethane resins, their number increases.
Strengthening the polyurethane resin is in contact with moisture in the subfloor and the air. It is an increasingly used to treat screed to floor installation works!
Before applying resin to be polished to a rough concrete floor was open pores. The resin is applied on cement screeds or calcium sulphate (gypsum), including heated floors. It is a versatile.
May act as a primer (fixing Dust), if installed directly over the resin flooring, while the 24-72 hours, depending on the type of resin used, and in this case will be used only reactive adhesives!
Attention! Use of polyurethane resin, the heating floors can be built only for your building / strengthening. These floors can not waterproofing (vapor barrier resin do not realize).

Some manufacturers indicate that the polyurethane resin can be given as a primer, some states that only forms a moisture barrier, while others will give all possible information about goods, and resin compatibility depending on the chemical nature of support and information about its compatibility with other materials or layers applied later.
Obs. Polyurethane resin is equal to price than epoxy but a lower cost / m vs. epoxy system. Once applied, absorbed in the substrate and cured, polyurethane resin should not form a surface layer on the substrate. Effect of strengthening, waterproofing and vapor barrier so and by impregnating resin screed mass acts as an organic binder addition leading to a substantial increase resistance to abrasion and plucking.
Polyurethane resins can be applied to the base with maximum moisture. 5% CM.
Polyurethane resin screed acts on the material: primer / fix traces of dust remaining after extraction, building / strengthening, waterproofing / vapor barrier, impregnation / Dust system.
Polyurethane product has a relatively high consumption / m, only if the screed leveling mechanical state is poor, requires additional maneuvers as it applied in two layers, and the last spread quartz sand, and another sand extraction operation, but does not require the applicator to use a certain period of time, the product component.
* If the polyurethane resin is applied correctly, in two layers and the last layer of quartz sand spread from 0.7 to 1.2 mm apron, after hardening resin and sand extraction in excess, will result in a highly rough surface that is ideal for casting compound. Now leveling / substrate is very good and is made of resin due to roughness layer of quartz sand.
If you dig ** rough is smooth and straight and the resin layer is no longer spread quartz sand, it is possible to directly install flooring adhesives reagents. Depending on the type of used polyurethane resin, flooring installation can be done after at least 2 hours and within 24 hours for curing polyurethane resin application fast and after at least 24 hours or 72 hours after application, if slow-setting resin using component reactive polyurethane adhesives, polyurethane bicomponent or monocomponent epoxy silane.
- Strengthening the polyurethane is strongly dependent on the type of resin used and the air humidity and dig.
- Strengthening of the second layer of resin is dependent on air humidity, so winter, with low humidity in heated rooms or if spread over resin and quartz sand, the setting time is prolonged!
*** If the resin layer spread from 0.1 to 0.3 mm quartz is possible to mount directly to floor, in a few weeks from the resin using reactive adhesives.
Polyurethane resin ****, whatever that is slow or fast curing, two component epoxy resin compared can not give in thick leveling screed surface as it dries excess layer swells in volume, is friable and has a low mechanical strength. In this case the surface is polished and given a new layer very thin (use 50-70 g / sqm).

Slow curing polyurethane resin
Is a polyurethane resin, without soventi, ready to use, slow curing. It is diluted and applied on absorbent substrates before sealing floors. It has a very low viscosity and good fluidity, high power of penetration in support. Consumption per square meter in the first layer can be a real status equalization mechanical screed. Application of polyurethane primer followed by scattering of quartz sand, the fresh resin is suitable for leveling with leveling compound works on all leveling screeds based on cement or calcium sulphate (gypsum), including heated floors. After application and drying is very low emission levels of volatile organic compounds (VOC) and is not dangerous for the applicant or partner. This product is printed on the packaging and marking data sheet with EMICODE GEV / EC 1R.
Economic: is an economic primer for training support. Consumption is approx. 0.2 to 0.30 kg / m layer. The material is ready. The remaining material can be used for other works.
Technical: its use is more pronounced as companies discover the advantages of this product.
Obs. Polyurethane primer, after application, it must form a surface layer to support as it swells and exfoliates. In case of the Baltic, the fresh product spread from 0.7 to 1.2 mm quartz sand apron!
Acts building / strengthening, waterproofing / vapor barrier and leveling compound on the resin molding sand can be done in two days from the primer. The resin, once applied to a leveling screed over the floor to be placed directly after curing forms on the surface an oily substance, specify. Because it is possible to mount directly reactive adhesives flooring for 72 hours after hardening resin. Avoid the oily substance is taken up and carried on the floor.

Fast curing polyurethane resin
Is a polyurethane resin, solvent free, ready to use, ultra fast curing! Contains 100% pure resin is more viscous than curing slow version, but has good fluidity and good penetrating power in support. Once the substrate, the resin layer hardens and is pedestrian about. 40 minutes. The second coat dries in 2 hours and then can paste directly on the floor or if the resin has spread from 0.7 to 1.2 mm quartz sand apron, you can pour leveling compound! This resin provides a great prompt and do not let it dries on the surface, oily substances. To install this type of flooring surface resin, reactive component will use polyurethane adhesives, polyurethane or epoxy bicomponent silane and bonding flooring is made within 24 hours after the resin. Otherwise, spread over resin quartz 0.1 to 0.3 mm apron! After application and drying is very low emission levels of volatile organic compounds (VOC) and is not dangerous for the applicant or partner. This product is printed on the packaging and marking data sheet with EMICODE GEV / EC 1R.
Economic: is an economic primer since it drastically cut the applicator and default costs. (One day system). Consumption is approx. 0.2 to 0.30 kg / m layer. The material is ready. The remaining material can be used for other works.
