Our materials are designed for strength, durability, and a unique design touch, adapting perfectly to the needs of project implementers.
Bi-component mortar based on anti-shrinkage, solvent-free, fast-hardening, hybrid polyester resins hardened with a mixture of catalyst powder, selected mineral charges and various additives.
CE-marked product as a system for the protection and repair of concrete structures in accordance with UNI EN 1504-6 “Anchoring of reinforcing steel bar”.
Thanks to its fluid composition, RESIMALTA 201 UP can be directly applied to the support without the need for a primer; furthermore, it perfectly fills the castable volume and ensures excellent sealing.
It resists well both to static and dynamic stress and its physical characteristics remain the same throughout the thickness of the cast thanks to a composition which prevents settling of inerts.
RESIMALTA 201 UP also ensures:
• Waterproofing features;
• Fast hardening;
• Excellent adherence to concrete, metal, stone, wood;
• Electric insulation;
• Ease of use: it is packaged in two pre-weighed components to avoid the possibility of mistakes when weighing.

Preparaion of the basement
The surface or hole to be treated must be clean, healthy, dry and mortar grout and crumbly part
free. For best adhesion concrete surfaces must be rough and the metal must be sandblasted to SA
2.5 degree: in case of threaded galvanized rods or enhanced adherence, degreasing is sufficient.
In case of under plate casting or where it is necessary, use a funnel or prepare a suitable formwork
with feeding hopper and exit breather pipe. To prevent the mortar from adhering to the formwork,
apply a detaching agent or a polyethylene foil.
Holes to fix rods must be made with revolving percussion drill and not through coring; they must
then be de-dusted, dried and cleaned.
In case of temperatures below +10°C, remove any possible humidity using compressed air and
heat the support for a few minutes using a gas blowpipe, otherwise do not apply.
Preparation of the product
The two components must be pre-dosed as per stoichiometric ratio.
Pour component B into component A and blend at slow speed for 3’ – 4’ using drill with helix/spiral
to reduce air inlet as much as possible; during this operation, scrape also the bottom and the sides
of the bucket.
Application
Cast the mortar in the volume to be filled.
Notes
With low temperatures, keep the product at 20 – 25°C for a few hours before application to foster blending and casting.
Packages are weight pre-measured out: fully use all components A and B. If you wish to divide the package, products
must be weighed by respecting the A+B ratio on the label and must not be weighed out based on the volume.
By pouring B component into A component, the hardening reaction starts: following mixture the time available is limited and it depends on the temperature.
| Temperature | Pot-life | Clamping at 120 Nm | Clamping at 400 Nm |
|---|---|---|---|
| 5 °C | 120 min | 150 min | 180 min |
| 10 °C | 70 min | 90 min | 100 min |
| 20 °C | 30 min | 45 min | 55 min |
| 30 °C | 20 min | 35 min | 45 min |
The data in the table above refers to an M20 threaded rod in which a bolt is screwed in with driving torque of at least 120
Nm and then of 400 Nm; the same times are valid also in case of rods with different diameter.
The temperature of the product is equal to that in which it has been kept for the past 3 hours.
The support temperature is generally lower than the air temperature during the winter season and higher in the summer
season.
At 20 °C complete hardening occurs after 24 hours.
On request, the specific inhibitor is available to slow down the reaction speed for applications in hot
climates.
Consumption
Calculate 1.6 kg/dm3 , specific weight of non-hardened product plus 10% scrap for each hole.
| Application type | Consumption |
|---|---|
| Structural anchoring of rebars | Approximately 2.0 kg/dm³ of volume filled |
| Filling of gaps and cracks | Depends on void size, approx. 2.0 kg/l |
| General mortar use | ~2.0 kg per dm³ of cavity |
Packaging and storage
Available in 5 kg packages (1,7 kg comp. A, 3,3 kg comp. B).
If stored in its original and sealed package, at temperatures between 10 and 30 °C, away from
moisture, heat sources and direct sunlight, the product remains unaltered for a year.
Protect from frost.
It is suitable for works carried out at low temperatures and it is used for:
• Casts under support plates of bridges, pillars, supports, footings and road joints;
• Holder and injections below rail-tracks of cranes, trolleys and precision machinery;
• Fast restoration of concrete floors and chipped joints;
• Fixing of runway lighting in airports;
• Concrete fast grouting of iron rods, stay wires, railings, poles;
• Reconstruction or new laying through casting of concrete prefab elements (ledges, chipped supports);
• Plugging through clogging of holes to fix water pipes and tubes;
• Filling and fast hardening of groves and breakings to place technical plants.
