Our materials are designed for strength, durability, and a unique design touch, adapting perfectly to the needs of project implementers.
Solvent-free epoxy coating for concrete, cement mortar floors and walls. Used as finishing of FINOMIX, MULTIMIX, RINFOMIX, STRATOMIX, ANTIMIX epoxy floorings.
It features high resistance to wear and tear and high chemical resistance.
RESICOLOR 424 is a solvent-free, epoxy resin-based coatings, hardened using cycle-aliphatic polyamines, and modified with special hydrocarbon polymers.
It creates a hard film with high mechanical features, in particular it shows high bending, traction, wear and tear resistance and has excellent adhesion to most supports if correctly prepared.
It results in waterproofing protection for concrete surfaces in contact with low to medium
concentrated organic and inorganic acid and basic solutions.
RESICOLOR 424 shows particular efficiency against concentrated sulfuric acid solutions up to
50%.
RESICOLOR 424 also has the following characteristics:
• high chemical resistance to most acid and basic chemical reactants;
• hardening by means of poly-addition resulting in extremely reduced shrinkage;
• possibility of application with low and high thicknesses;
• smooth or “orange peel” finishing;
• fast hardening and commissioning 48÷72 hours after application.

Preparation of the support
The surfaces to be coated must be compact, clean, dry (<5% humidity) and crack, crumbly part and cement grout-free. For better adhesion the surface needs to be slightly roughened using sand paper, diamond wheel or silicon carbide or acid washing smoothing; then remove any trace of dust and dirt using an aspirator.
Cement supports affected by rising damp must be treated with two coats of RESICOL 118 (vapour barrier).
Very porous concrete surfaces or surfaces with cracks and omega cavities need to be levelled in advance with RESICOL 100, epoxy adhesive.
Application of the adhesion primer
Roller or brush apply RESICOL 160, a highly penetrating epoxy primer which aids adhesion on very porous materials. 200 – 300 g/m2consumption.Wait at least 24 hours before applying
RESICOLOR 421/2.
Alternatively, use RESICOLOR 451 epoxy varnish in watery emulsion, diluted with 5 – 10% water.
Metals need to be sandblasted to SA 2.5 degree or alternatively grinded or treated with metal brush and varnished using RESICOLOR 425 specific primer.
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, carefully scrape also the bottom and the sides of the bucket.
In the event of partial use of the package, the two components must be carefully weighed in weight following the ratios on the label.
Application
Brush, roller or airless spray apply, in at least two layers, with average consumption per layer of 200 – 300 g/m².
Note
This product cannot be applied on surfaces which are not completely dry. Apply on concrete only after it is completely cured. Do not apply on fine mortar. Always apply at temperatures of at least three degrees above the dew temperature,
the dew temperature must not be reached for at least 24 hours after application.
Packages are weight pre-measured out: in case of partial use of the package, components must be weighed by respecting the A+B ratio on the label and must not be weighed out based on the volume.
Application with temperatures lower than +10 °C and higher than +40 °C is not recommended.
Following mixture, the reaction between the two components takes place immediately. Processing time is therefore limited and depends on temperature.
| Temperature | Pot-life | Dust free | Paintable again after |
|---|---|---|---|
| 10 °C | 70 min | 22 h | 24 h |
| 20 °C | 30 min | 10 h | 14 h |
| 30 °C | 20 min | 4 h | 6 h |
Minimum hardening temperature: 5 °C.
Application with temperatures lower than +5Cº and higher than +30Cº is not recommended.
Full hardening takes place after seven days with a temperature not lower than 10 C°.
After at least 48 hours from application have gone by, it is necessary to sand the surface with abrasive disc pads (120 grain), before proceeding with painting.
| Use case | Consumption |
|---|---|
| Standard use | 200–400 g/m² |
Available in 5, 10 and 25 Kg packages (A + B).
If stored in its original and sealed package, the products remains unaltered for 18 months if kept in a closed and protected environment with a temperature between 10 and 30 °C.
