IMPEPRIME® NEXT DAY is a one component, polyurethane primer. It is just one of many primers that have been designed to be used with the IMPETHANE® system. Priming is essential to ensure excellent adhesion which in turn prevents system failure. IMPEPRIME® NEXT DAY is characterised by its low viscosity and curing speed. It has great properties which result in it having excellent impregnation and paint-over times on many substrates. Additionally, it can be effectively used on both dry and wet concrete.
Ensure surface is completely clean before proceeding. Using a high-pressure washer if possible. If there is any moss present, ensure it is removed. We recommend using a fungicidal wash. Ensure no chemical residue is left behind. Do not continue until surface is completely dry. You can use squeegees and mops to speed up the process. Apply with a brush or roller at a maximum consumption of 200g/m2. Consumption may need to increase if you are applying primer to more porous substrates. IMPORTANT: less is more when it comes to priming. Avoid pooling of primer, you only require a thin film across the surface. Excessive primer can cause system failure.
FEATURES AND BENEFITS
- One Component
- Low Viscosity
- Excellent Impregnation and Paint-over time.
- Strong Adhesion even on non-porous substrates.
Recommended Primer for:
- Concrete structures (including wet/damp structures)
- Ceramic Tiles
- Non-porous Substrates
DRYING TIME: Dry to touch in 6-12 hours (temperature dependent). The main membrane/reinforcement can be applied after 24 hours. If more time passes (+4days) or if you are unsure about adhesion, contact our technical team. If it rains or the primer gets wet, dry surface and re-apply primer.
CONSUMPTION RATES: Apply with a brush or roller. Coat the entire surface at a minimum consumption of 200g/m2. This may vary depending on the porosity of the substrate. With increasing porosity, primer usage should increase. If you are unsure, get in touch.
CLEANING: Ensure tools are cleaned first using paper towels and then solvent. Rollers will not be reusable.
STORAGE: Ensure pails are stored in dry places and at temperatures between 5-25oC.
SHELF LIFE: Can be kept for 12 months minimum in original unopened pails Once opened use as soon as possible.
This product will discolour if left exposed. This will not affect the functionality or success of the membrane. It is purely aesthetic. For extremely porous substrates, consumption will have to increase in order to reach required film thickness along substrate surface. For very porous substrates IMPEPRIME® SAME DAY is recommended, as it does not penetrate the substrate as much, and will give the required film thickness to achieve required adhesion.
The adhesion strength of IMPEPRIME® NEXT DAY exceeds EOTA requirements.

IMPERVIOUS systems vary to suit you as the applicator. Some allow the application to be completed in one day, others within two days. The one-component systems remove the need to mix in an additional product. Our range of IMPERVIOUS additives enable our systems to suit any application time-frame.
