Preparation of the basement
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 sandblasting, suck up the dust and then roller or brush apply the epoxy primer RESICOL 115 both on concrete and on reinforcement rods is they are exposed (in case of damp support use RESICOL 116 primer): concrete must be applied immediately after laying the primer, layer upon layer.
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, then slowly add with agitation component C until an even mixture is reached.
Application
Apply the mortar on the primer, layer upon layer, respecting the times of use (see table) with trowel, palette knife or other suitable tool based on the type or work.
RESIMALTA 212 can be applied on low and 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 hardening.
If the surface treated with RESIMALTA 212 must ensure perfect waterproofing, roller and/or brush apply one or more layers of RESICOLOR 421, a coloured solvent-free epoxy compound,
Notes
Packages are weight pre-measured out: fully use all three components A, B and C.
If you wish to divide the package, products must be weighed by respecting the A+B+C ratio on the label and must not be weighed out based on the volume.
Three essential rules are valid for all bi-component and tri-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 | 90 min | 9 h |
| 20°C | 60 min | 7 h |
| 30°C | 35 min | 5 h |
| 40°C | 20 min | 4 h |
Full hardening is achieved after 7 days.
Maximum time of application of the mortar following primer buttering.
| Temperature | Open to traffic |
|---|---|
| 10 °C | 24 h |
| 20 °C | 16 h |
| 30 °C | 10 h |
Consumption
Primer RESICOL 115: 0.4 – 0.5 kg/m²
To execute a carry 1cm thick with RESIMALTA 212 the consumption is of approx.21 kg/m².
Packaging and storage
Available in 25 kg packages (A + B + C component).
RESIMALTA 212 remains unaltered for 18 months if stored in a dry and sheltered place at a temperature between +10°C and +30°C in its original sealed containers.
RESIMALTA 212 is a product which was specifically designed for the creation of adjusting block of stones
under tracks for railway superstructure: it is placed between the connection plates of the tracks and the
extrados of the support concrete.
