(*) hardness values are supplied only for the binding part, A + B component, because the inert does not allow even data: full mixture A + B + C has hardness values higher than those shown in the table.

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’ using drill with 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.


Note

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.

When mixing, the reaction between the two components starts: the time available is limited and it depends on temperature.

temperaturepot lifehardening
10 °C60 - 70'8 hours
20 °C35 - 45'5½ hours
30 °C20 - 35'3½ hours

Complete hardening is achieved after 7 days.

To fill a volume of 1 dm3 with RESITAR 30 A mortar 1.5 kgs of product are necessary.
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.
