| Shore A hardness (only A+B) | 92 |
| Shore D hardness (only A+B) | 48 |
| Adhesion to dry concrete | Cohesive break of the substrate |
| Adhesion to wet concrete | 3 N/mm² |
| Density | 1.50 kg/dm³ |
| A + B + C mixture ratio | 0.7 + 1.4 + 2.4 |
Preparation of the foundation
The surface to be treated must be clean, whole, dry and mortar grout and crumbly part-free: ideal
adhesion is achieved by roughening it with sandblasting treatment followed by thorough suction.
Concrete must be fully cured (28 days).
Preparation of the product
Pour component B into component A and blend at slow speed for 3÷5 minutes using a drill fitted
with a helix/spiral; during this operation, scrape also the bottom and the sides of the bucket, then
slowly add component C (inert) and blend until an even and lump-free mixture is achieved.
Application
Cast RESITAR 30 mortar in the volume to be filled.
Notes
Packages are weight pre-measured out: fully use all three components A, B and C.
If you want to divide the package, the products must be weighed according to the A+B+C ratio on the label and must not
be weighed by volume.
Pouring component B into component A starts the curing reaction: after mixing, the time available is limited and depends on the temperature.
| Temperature | Pot-life | Hardening |
|---|---|---|
| 10°C | 60-70 min | 8 hours |
| 20°C | 35-45 min | 5½ hours |
| 30°C | 20-35 min | 3½ hours |
Minimum hardening temperature: +8°C. Complete hardening: at least 7 days following application at 23±2 °C.
Consumption
About 1,5 kilograms of product are needed to fill a volume of one dm3.
Packaging and storage
Available in 4,5 kg packages (A + B + C components).
RESITAR 30 A remains unaltered for a year if stored in a dry and sheltered place at a temperature between +10°C and +30°C in its original sealed containers.
Keep away from frost, heat sources and direct sunlight.
