Spectrum ScratchCote is used to prepare surfaces with a significant negative texture or uneven finish. Typical examples include asphalts such as SMA, tamped concrete, surface dressing & other similar surfaces. ScratchCote is an MMA void filler which is applied to the surface and hardens rapidly, providing a flat & even surface for the application of other Spectrum and DekorGrip systems.
Features and Benefits
- Provides an even surface, leading to a high quality finished project
- Allows continuous application with no down time, due to fast cure time
- Accepts wide range of finishes
- Increases coverage rates of final finish, providing cost savings
- Supplied pre-packaged & ready-to-mix for simplicity & speed
- Solvent-free formula"
Surface preparation: The application surface should be sound and clean, free from grease, oil, rust, scale, dirt, or any other soiling that might affect adhesion or performance. In any case, but especially in the case of overcoating existing markings, it is further recommended that test areas be coated to ensure good adhesion and/or compatibility with the substrate.
UltraScratchCote is packaged ‘ready to use’, with a high performance resin that needs to be mixed with the powdered filler product.
Open the outer carton & remove resin, gloves, mixing stick & plastic disc from the carton. Replace lid & shake carton gently to loosen the filler product.
Open the resin & stir, then add to the filler & mix for approximately 3 minutes with a low speed mixing drill to ensure thoroughly mixed.
Ensure areas around the surface to be coated are protected from splashes or over-runs, using gaffer tape or similar to mask off.
Pour out the mixed product onto designated area and spread around evenly with a flat squeegee to create a level and even finish.
Do not apply when the air or surface temperature is below 5°C or less than 3°C above dew point, or if this is likely to occur during the curing period.
Do not apply when there is rain, mist, fog, or snow imminent; when humidity is high or the surface is wet with condensation or likely to be during the drying period.
The times given below are guide times and may vary according to specific site conditions
