Preparation of the support
The surface to be treated must be clean, healthy, dry and mortar grout and crumbly part-free. Best adhesion is achieved by roughening it by sandblasting.
Application on metals follows careful preparation of the support: remove oils, fats, varnishes and rust by abrading or sandblasting with white metal (SA2 – SA 3 degree).
After sand-blasting, vacuum the dust and then apply RESICOL 115 epoxy primer both on the concrete and on the armour rods if they happen to be exposed.
Preparation of the product
Pour component B into component A and blend at slow speed for 3’ – 5’ 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; the mortar must be even before application.
Application
Apply the mortar on the primer, layer upon layer, within the times of use (see table) with trowel,
palette knife or other suitable tool based on the type of work to be done.
RESIMALTA 205 may be applied with low or high thicknesses with no hardening or shrinkage problems.
In case of thicknesses greater than 3 cm applied on vertical or overhead surfaces we recommend
supporting the mortar with a board or formwork until it hardens.
Notes
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.
Three essential rules are valid for all bi-component systems: weigh well, carefully mix bottom and walls, observe times of
use.
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 | Hardening |
|---|---|---|
| 10 °C | 80 min | 8 h |
| 20 °C | 50 min | 6 h |
| 30 °C | 25–30 min | 4 h |
Full hardening is achieved after 7-days of curing at about 23 °C.
Consumption
Primer RESICOL 115: 0.4 – 0.6 kg/m²
The consumption to create a new layer 1 cm thick with RESIMALTA 205 is approx. 20 kg/m².
Packaging and storage
Available in 10 kg and 25 kg packages (A + B component).
RESIMALTA 205 remains unaltered for at least a year in a dry and sheltered place, at a
temperature from +10 °C to +30 °C in its original sealed containers.

• Execution of connecting bases in the corners between walls and floors;
• Restoration of concrete for high chemical protection interventions;
• New layers with medium-high thickness to create new inclinations;
• Restoration of chipped joints in industrial floorings;
• Restoration of corners, steps, low walls, balconies, concrete skirting boards;
• Execution of layered surfaces subject to chemical aggression and mechanical abrasion;
