RESITAR 30 M
TRI-COMPONENT THIXOTROPIC EPOXY-BITUMEN MORTAR FOR MENDING AND RESTORATIONS
Three component, solvent-free epoxy mortar, with coal tar additive, specifically for the construction of road joints, kerbs and restoring asphalt surfaces.
- High mechanical compression strength and shock resistance;
- Excellent weather resistance and good waterproofing;
- High adhesion to dry and damp concrete (with prior application of specific primer);
- Excellent resistance to alkali, saline solutions (especially de-icing salts), sewage, oils, fats and low concentration acid solutions;
- Good workability using standard working tools;
- To be used with support temperature from +5 °C and +30 °C;

(*) 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.
On dry concrete use RESICOL 115 epoxy primer. Use also on reinforcement rods if they are exposed.
On damp concrete, asphalt and bitumen, use RESICOL 116 epoxy primer.
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
Apply the mortar on the primer, layer upon layer, within the times of use (see table) with trowel, palette knife or suitable tool based on the type of work to be carried out.
RESITAR 30 M can be applied with high or low thicknesses with no hardening or shrinkage problems.
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.
When mixing, the reaction between the two components starts: the time available is limited and it depends on temperature.
