An aerosol-contained clear adhesion promoter for use with Magma and Spectrum branded preformed thermoplastic products.
ProTack is a convenient primer for use on concrete and asphalt and surfaces before installation of thermoplastic products, particularly preformed thermoplastic. ProTack leaves a clear tack for improved adhesion of thermoplastic to surface which increases product longevity. Features and Benefits:
- Increased adhesion of thermoplastic to substrate
- Easy application from aerosol
- Ready to use straight from the can
- Fast drying to enable rapid application of thermoplastic
The application surface should be dry, 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 line markings, it is further recommended that test areas be coated to ensure good adhesion and/or compatibility with the substrate/previously applied coatings.
Tarmac – weathered - It is recommended that asphalt and other similar surfaces be allowed to through harden for up to 6 months before application. Test trials should be carried out in the first instance on a small area.
Concrete & other cementitious surfaces – including powerfloat, tamped or brushed concrete, monoblocks & pavers – Ensure surface is sound, clean and free from laitance – we recommend a preparation method suitable for the specific location and surface is carried out before application of product, to ensure surface is properly prepared back to clean and sound substrate.
Examples of preparation methods that may be suitable are captive shot blasting, diamond grinding, scabbling or planing. It is critical that utmost attention is paid to cleanliness and good workmanship, whatever preparation method is used, as the presence of any loose material, dust, soiling or previous coatings are likely to reduce adhesion of new coatings.
New concrete should be left to harden before coating, as the curing process and residual moisture content can lead to product de-lamination if coated too early.
Shake can thoroughly for at least 90 seconds before use
Apply as an ordinary aerosol, and allow to dry for 10-15 minutes. Once dry, apply thermoplastic markings.
If surface is particularly porous, 2 applications may be required
Do not apply when: either the air or surface temperature is below 5°C; when there is mist, fog, or snow; when rain is imminent; when humidity is high or when the surface is wet with condensation; either during the application or likely during the drying period. Do not use in high humidity. Surface temperature must always be a minimum of 3°C above dew point.
Touch dry: 5 minutes @ 15oC
