Instruction for preparation and application.
During the processing of WATERFIX XP TH dry mortar mixes it is generally necessary to comply with the principles contained in the relevant technological process BETOSAN for repair of reinforced concrete structures (TP # 1/06)
Base. Any incoherent, loose, weatherworn or otherwise visibly damaged concrete shall be completely removed from the surface of the base. Corroded reinforcement shall be carefully released and cleaned of any corrosive products. Before application of repair material, humidification of the base surface shall be properly and repeatedly performed for at least 120 minutes. The properly humidified concrete shall be dully dump, and not covered with dump shining water film. Substrate can be cohesive masonry as well. It is possible to anchor the material to substrate by adhesion bridge DENSOCRETE 111 or mechanically.
Preparation of mortar.
The mortar is prepared by simple mixing with water. During mixing, it is necessary
to use a low-speed mixer with forced circulation. Recommended mixing ratio is shown in the following table:
| Type of mortar | max size of fillers | recommended mixing ratio | applied layer thickness | ||
| dry component (kg) | water (liters) | min. (mm) | max. (mm) | ||
| WATERFIX XP TH f fine | 1 mm | 25 | 3.75 ÷ 4.00 | 3 | 12 |
| WATERFIX XP TH r medium | 4 mm | 25 | 3.50 ÷ 3.75 | 10 | 25 |
| WATERFIX XP TH c coarse | 8 mm | 25 | 3.45 ÷ 3.70 | 20 | 40 |
The recommended batch of water can be adjusted to reach optimum workability. If added water exceeds the recommended quantity by 10%, risk of cracking is significantly enhanced. It can also lead to drop of mechanical properties.
Workability of the product is 50 – 60 minutes under 20 °C
Neither temperature of base nor temperature of ambient air shall be below + 5°C and above + 30°C.
Mortar application. WATERFIX XP TH can be applied either manually or mechanically by dry or wet spraying. The mortar can be manually applied either by rendering or fining off. First layer (connecting) needs to be applied in such a way to ensure that no unfilled spaces are created behind reinforcement, in caverns etc.). After initial application it is recommended to spread the mortar into pores and uneven spaces. This can be done well with flat paint brush with short hair, or by a toothed trowel. Proper adhesion of the material to substrate in application stage is basic condition for good quality adhesion in the final state. In localized repairs it is necessary to pay appropriate attention to edge regions or repaired area, where the edge needs to be properly compacted, without entrapped air pockets or other non-homogeneities. The repair is always done from place of deepest degradation, in such a way that the final layer it to be continuous over entire area, if possible.
Surface finalization. After initial setting of the last layer, smoothing by a dry polyurethane finisher is used for surfacing. Wet surfacing is not allowed. If the surface is to be smoothed with fine spread coating (e.g. DENSOFIX), ruling off by a wooden tamper is sufficient.
Surface treatment Repaired surfaces shall be properly treated immediately after completion to avoid especially direct exposure to sun, wind effect and other factors accelerating undesirable evaporation of the batch water. Use of the treatment agents DENSOCURE W and DENSOCURE R proved well
Specific consumption
Specific consumption of dry mortar is 1.7 ÷ 1.8 kg/m2 at 1 mm of layer thickness. In spray application, it is necessary to count with loss of 10 ÷ 12 %

Instruction for preparation and application.
Base. Dirt and incoherent, loose or otherwise visibly damaged concrete shall be completely removed from the base before application. Corroded reinforcement, if any, shall be cleaned of any incoherent corrosive products. Tensile strength of surface layers of the concrete base should be optimally on the level of 1.5 MPa. Before application, humidification of the surface of the base shall be properly and continually performed for at least 120 minutes. Before casting, the surface shall be dully damp, and not covered with shining water film. Rapidly leaking areas of the structure need to be drained using drainage hoses and after full surface application of the material close the drainage openings with rapidly setting hydroinsulation putty WATERIFIX rapid.
Preparation of mix. The mix is one-component and is mixed with water only. Pan concrete mixer can be used for preparation of the mix or in case of preparation of small amount, the mix can be mixed with a propeller mixer driven by an appropriate electric drill. Add 1,95 ÷ 2,25 l of water to 15 kg of mix (1 pail). This mix can be applied by the dry spraying. Regular gravity mixers cannot be used for mixing of this material due to very short setting time. When preparing larger volume of the material it is necessary take into account that workability of the mix is 10 to 15 minutes at 20°C.
Workability of the mix is 10 – 15 minutes at 20°C. Workability time adequately shortens at elevated temperatures. Neither temperature of concrete substrate nor temperature of ambient air shall be below + 1°C and above + 35°C. Mix has limited capacity to cure in freezing condition
The mix is appliedby two methods – classical rendering or so called dry spraying. Manual application can be done by setting or spreading. First layer (connective) needs to be applied in such a way to prevent creation of any cavities (behind rebar etc.). After first application of the mortar it is recommended to spread the mortar into pores and holes in the substrate. It is recommended to use flat brush or saw-tooth trowel. Proper workmanship is basic condition for quality adhesion. When applying local repairs it is necessary to take good care to remove any voids or pores from edge of the local repair. Repair mix should be always applied from the area of deepest damage in such a way that the final layer will be continuous.
Finalization of the surface. After the initial setting standard processes (smoothing by a float, steel trowel or polystyrene finisher) are used for surfacing. No additional water shall be worked up into the surface.
Surface treatment. Concrete surface shall be protected against direct sunshine and wind immediately after completion. Intensive treatment shall be carried out 3 to 6 hours following the application. Optimal treatment is to cover the surface with permanently moistened geotextiles.
Specific consumption
Specific consumption of dry mortar is 1,8 kg/m2 at 1 mm of layer thickness.

Instruction for preparation and application.
During the processing of dry mortar mixes MONOCRETE PPE TH it is generally necessary to comply with the principles contained in the relevant technological process BETOSAN for repair of reinforced concrete structures (TP n.1/06).
Base. Any incoherent, loose, weatherworn or otherwise visibly damaged concrete shall be completely removed from the surface of the repaired base. Corroded reinforcement shall be carefully released and cleaned of any corrosive products before application of repair material, humidification of the base surface shall be properly and continually performed for at least 120 minutes. The properly humidified concrete shall be dully dump, and not covered with dump shining water film. If necessary, it is possible to anchor the material to the base with the adhesive bridge DENSOCRETE 111.
Preparation of repair mortar. The mortar is prepared by simple mixing with water. During stirring it is necessary to use a low-speed mixer with forced circulation. The recommended mixing ratio is specified in the following table:
| Indication/type of mortar | max size of fillers | Recommended mixing ratio | Thickness of applied layer in single working area | ||
| Dry component (kg) | Water (litres) | min. (mm) | max. (mm) | ||
| MONOCRETE PPE TH f fine | 1 mm | 25 | 3,70 ÷ 3,95 | 5 | 12 |
| MONOCRETE PPE TH r medium | 4 mm | 25 | 3,45 ÷ 3,70 | 10 | 25 |
| MONOCRETE PPE TH c coarse | 8 mm | 25 | 3,40 ÷ 3,65 | 20 | 40 |
Workability of the product is 50 – 60 minutes under 20 °C.
Neither temperature of base nor temperature of ambient air shall be below + 5 °C and above + 30 °C.
Mortar application can be done either manually or by dry or wet spraying. The mortar can be manually applied either by rendering or fining off.
First layer (connecting) needs to be applied in such a way to ensure that no unfilled spaces are created (behind reinforcement, in caverns etc.). After initial application it is recommended to spread the mortar into pores and uneven spaces. This can be done well with flat paint brush with short hair, or by a toothed trowel. Proper adhesion of the material to substrate in application stage is basic condition for good quality adhesion in the final state. In localized repairs it is necessary to pay appropriate attention to edge regions or repaired area, where the edge needs to be properly compacted, without entrapped air pockets or other non-homogeneities. The repair is always done from place of deepest degradation, in such a way that the final layer it to be continuous over entire area, if possible.
Surface finalization. After initial setting of the last layer, smoothing by a dry polyurethane finisher is used for surfacing. Wet surfacing is not allowed. If the surface is to be smoothed with fine spread coating (e.g. DENSOFIX), ruling off by a wooden tamper is sufficient.
Surface treatment. Repaired surfaces shall be properly treated immediately after completion to avoid especially direct exposure to sun, wind effect and other factors accelerating undesirable evaporation of the batch water. Use of the treatment agents DENSOCURE W and DENSOCURE R proved well.
Specific consumption
Specific consumption of dry mortar is 1.7 ÷ 1.8 kg/m2 at 1 mm of layer thickness. In spray application, it is necessary to count with loss of 10 ÷ 12 %.
