tiksotropny nonshrinking fibroshpatlevka for concrete restoration
appointment
Superficial restoration of the damaged concrete constructions (both horizontal, and vertical surfaces).
TYPICAL CASES OF APPLICATION
- restoration of the damaged surfaces of concrete, corners of columns and beams, edges of the balconies destroyed because of corrosion of fittings;
- reinforced concrete restoration;
- smoothing down of superficial defects, such as gravel nests, new filling seams, openings from timbering struts, open cores of fittings, etc.
- filling of rigid seams;
- repair of the surfaces which were exposed to intensive attrition (channels, floors on productions, ramps, etc. )
- smoothing down of the parts of a wall and tunnels concreted in a trench.
- repair of viaducts of the highway and railroads.
DESCRIPTION OF THE PRODUCT
MAPEGRAUT TIKSOTROPNYY represents the powder, ready to mixing, consisting of high - strength cement, synthetic fibers, special fillers and additives; the compounding is developed by MAPEI firm.
At mixture with MAPEGRAUT TIKSOTROPNYY water turns into easily processed solution with so high tiksotropichnost that it can be used without timbering even on vertical surfaces. Admissible thickness of a layer: 30 - 35 mm.
After hardening of MAPEGRAUT TIKSOTROPNYY gains the following properties:
- very high durability at a bend and compression;
- the elasticity module, coefficient of thermal expansion and vapor permeability are close to similar indicators of high - quality concrete;
- water tightness;
- high adhesion to old concrete (provided that the last is previously plentifully moistened with water), and also to fittings, especially if it is processed by structure of MAPEFER;
- high resistance to attrition.
- do not use MAPEGRAUT TIKSOTROPNYY on smooth concrete surfaces: make them rough and if necessary enter fittings;
- do not use MAPEGRAUT TIKSOTROPNYY for anchoring (use MAPEFIL).
- do not use MAPEGRAUT TIKSOTROPNYY for restoration of constructions in the way of filling in a timbering (use MAPEGRAUT EASY - FLOWING).
- do not add cement, fillers or additives to MAPEGRAUT TIKSOTROPNYY.
- do not add to MAPEGRAUT TIKSOTROPNYY water after mix began to grab;
- do not apply MAPEGRAUT TIKSOTROPNYY at temperatures below + 5o Page.
- do not use material if packing is damaged or if it was earlier opened.
- The basis has to be firm and strong, for this purpose remove the damaged or badly keeping concrete. There have to be also udalenyrezultata of the restoration made earlier which do not have strong coupling with a surface.
- Purify sandblasting concrete and fittings of dust, rusts, cement, solution, greasing, oil and the paint applied earlier.
- Plentifully moisten a surface with water.
- Before putting solution let's evaporate to surplus of water. If necessary use compressed air or a sponge for removal of water from a surface.
- Pour the amount of water necessary for the consistence corresponding to a way of drawing in a mixer:

Preparation of the basis
Solution preparation
Way of drawing | Amount of water, l on a bag of 25 kg |
flat pallet | 3,9 - 4,1 |
spray | 4,0 - 4,3 |
- Include a concrete mixer, slowly and continuously fill up MAPEGRAUT TIKSOTROPNYY in water.
- Mix mix within 1 - 2 min. , scrape off not stirred powder from walls of a mixer and mix 2 - 3 more min.
- Depending on the prepared quantity it is possible to use a mixer for solution or a drill with a nozzle for hashing. Hashing has to be carried out at a small speed to avoid introduction to mix of excess amount of air.
- Solution can be prepared in the manual way only as an exception. In this case prepare small amounts and mix solution not less than 5 - 6 min. (until mix does not become completely uniform).
ATTENTION: manual preparation demands a large amount of water that harmfully affects such characteristics of material as mechanical durability, shrinkage, water proofness, etc.
Viability of MAPEGRAUT TIKSOTROPNYY solution - about 1 hour at + 20o Page. Expansion of material is calculated in such a way that it compensates hygrometric compression. For bigger efficiency expansion can be compensated if to use the corresponding fittings or a timbering around a construction.
At a thickness of layer more than 2 cm of MAPEGRAUT TIKSOTROPNYY it is possible to use without timbering, only if the surface was made rough and the fittings were used. The layer not less than 1 cm thick has to close fittings.
Layers of smaller thickness can be put without fittings provided that the surface is rather rough for expansion compensation. Process of expansion comes to the end during the first days of hardening.
Putting solution
Solution can be applied with the pallet, the timbering is not required even on vertical surfaces and ceilings; maximum thickness of one layer of 30 - 35 mm.
MAPEGRAUT TIKSOTROPNYY can also be sprayed by the corresponding plaster car of rotor or screw type.
It is recommended to process before use of MAPEGRAUT TIKSOTROPNYY filling fittings by anticorrosive structure of MAPEFER.
Each subsequent layer can be put only after full hardening previous (no more than 4 hours at + 23o C).
Process of restoration can be considered as MAPEFINISh finished after drawing finishing protective structure or the ELASTOKOLOR protective paint.
Precautionary measures which need to be observed when drawing and hardening
- At a temperature about + 20 ° C special precautionary measures are not required. In hot weather you do not store material on a sunlight, at preparation of solution use cold water.
- In cold weather water temperature, used for mixing, has to be near + 20o Page.
- Avoid fast evaporation of water when hardening MAPEGRAUT TIKSOTROPNYY solution since it can cause cracks on a surface as a result of plastic shrinkage. Spray water on a surface within the first 24 hours of hardening or apply the structures which are slowing down evaporation.
- The structures which are slowing down evaporation can be used only in case the subsequent coverings are not provided.
