Vetotop MC362

All surfaces must be structurally sound, clean, and completely dry prior to application. Any traces of old paint, dust, grease, oil, mold, salts, or other surface contaminants must be thoroughly removed. 

Mechanical preparation methods, such as grinding or shot blasting, are recommended to achieve a clean, roughened, and sound substrate, free from laitance, release agents, and surface protrusions. 

The surface moisture content shall not exceed 8%, and the substrate pH must be no greater than 9. During both preparation and application, the substrate temperature must not fall below 5°C.

If required, prepared concrete substrates may be primed using Vetoprime MP367 to enhance adhesion and seal the surface. The primer should be applied evenly using a roller or brush, ensuring full coverage without pooling. Allow the primer to cure completely before applying Vetotop MC362. On highly porous or uneven surfaces, a second coat of Vetoprime MP367 may be necessary to achieve full substrate saturation. Do not apply on wet or damp surfaces.

Vetotop MC362 is supplied as a two-component system, consisting of Part A (base) and Part B (Hardener). Prior to mixing, Part A must be stirred thoroughly using a low-speed mechanical mixer (300–400 rpm) to ensure a uniform consistency. Once adequately stirred, add the entire quantity of Part B into Part A, and mix rapidly and continuously until a homogeneous mixture and uniform color are achieved. Care must be taken to ensure complete blending, as insufficient mixing may affect the performance of the applied material. 

The correct mixing ratio must be strictly observed to achieve optimal results. The mixed material has a limited pot life of approximately 10 to 12 minutes at 20°C and should be applied immediately after mixing to avoid material wastage and to ensure proper workability. Over-mixing should be avoided to minimize air entrainment

Vetotop MC362 shall be applied only under controlled environmental conditions, ensuring that the substrate temperature is not less than 5°C and the relative humidity does not exceed 70%. 

The material may be applied using a squeegee, trowel, roller, or approved mechanical equipment, depending on the system type. For anti-skid systems, the first coat should be applied at a thickness of 1000 µm using a squeegee or trowel, followed immediately by broadcasting silica sand aggregate uniformly onto the wet surface using the dropon method. Once fully dry, any excess aggregate must be removed, and a second coat should be applied at 500 µm using a roller. 

In road marking applications, for plain line markings, one coat is applied using a roller, drop box, hand-pushed, or extrusion machine, with glass beads added to enhance reflectivity as required. For Spotflex, textured, or profile applications, the material should be applied using extrusion-type or handpushed machines, with the option of adding glass beads. Vetotop MC362 is supplied ready to use and should not be thinned under any circumstances.

Drying times are influenced by ambient temperature, air circulation, and the applied film thickness. Under standard conditions at 25°C, the material typically reaches a hard dry state within 30 minutes and can be opened to traffic after the same period, provided proper curing has been achieved.

All tools should be cleaned with Vetonit Solvent XX400 immediately after use. Hardened material can only be removed mechanically.
