A versatile clear primer that is used to prime concrete and cementitious surfaces before application of thermoplastic screed, or solvent based epoxies and acrylics.It is a single-pack product that is very fast drying. This enables minimum delay before overcoating and removes the failures associated with slow drying and ineffective tack coat or similar products.Ideal for use on all concrete finishes, blocks and pavers. Can be applied by hand, or sprayed effectively through airless spray equipment for rapid and accurate application without the overspray associated with inferior products.

Features and Benefits:
- Very fast drying to enable greater productivity
- Works with epoxy paints and thermoplastic
- Clear finish to avoid the unsightly effect of black tackcoat on concrete surfaces
- Compatible with airless or handsprayer systems for rapid application
- Proven to be far more effective than traditional tack coats
- Dries even at lower temperatures, to extend the working season
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 line markings, it is further recommended that test areas be coated to ensure good adhesion and/or compatibility with the substrate.
Concrete and other cementitious surfaces – including powerfloat, tamped or brushed concrete, monoblocks and 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 delamination if coated too early
This product is supplied ready to use and need not be thinned. The product remains in suspension very effectively, but it is good practice to stir before use.
If thinning is required, for use in airless sprayer, Type II Thinner may be used, up to 20% by volume. It is rare to need to thin, as the formulation is suitable for most equipment without any thinning.
We recommend the use of airless spray equipment as it allows fast application with minimum overspray. Standard lining spray tips can be used, but do not over-apply. Typical hole sizes would be 13 - 17 thou, with spray fan angle to suit application and line width.
However, rollers or brushes can be also be used if spray equipment is not available. We recommend a short pile roller - do not use foam heads as they tend to be affected by the solvent content.
