Consistent Application on All Surfaces
Specially formulated viscosity allows seamless adherence to horizontal and vertical surfaces.
Prevents excessive runoff or overexposure in grooves and valleys.
Superior Performance in Tough Conditions
Advanced formula excels in warmer or windy environments.
Reduces wash-off time significantly compared to other retardants.
Extensive Distributor Network
Reliable and fast supply through an extensive network of Prime Exposure stockists.
Labor and Time Saving
Minimizes labor and time while delivering outstanding, consistent results when applied correctly.
 
2. Coverage
A 20-liter drum of Prime Exposure Retarder covers approximately 80–100 m².
 
3. Application Tips:
Dilution and Coverage
Apply Prime Exposure Retarder undiluted at a rate of 0.2–0.3 liters per square meter.
Ensure the surface is troweled, bleed water has dried, and sufficient surface moisture is present for optimal pitting.
Application Method
Do not trowel the product directly onto the surface.
Use a spray unit capable of covering the entire area in one application for even results.
Protection in Warm/Windy Conditions
Use builders’ film (polythene) or spray Prime Exposure Evaploc to protect the surface.
Refer to the Prime Exposure Evaploc Technical Sheet on our website for detailed instructions and dilution rates.
Wash-Off Timing
Wash off the surface when the fluorescent green color fades, and the retarder has set.
For temperatures above 23ºC or windy conditions, wash off four hours post-application.
Same-day wash-offs require advanced experience to avoid uneven exposure.
Best Practices for Results
For optimal results, wash off the surface the following day.
This minimizes the risk of overexposure or underexposure, ensuring a flawless finish every time.
