Areas of Application
MMAXGRIP PRMX Primer is used for the pre-treatment (primer and barrier) of slightly absorbent mineral and timber substrates (concrete, screed, wood, etc.) in preparation for the later application of Ennis-Flint waterproofing/surfacing products such as Ennis-Flint MMAXGrip PRMX 45 and Ennis-Flint MMAXGRIP PRMX 65.
Included in Pack
- 10.00kg MMAXGRIP PRMX Primer
IMPORTANT: Ennis-Flint MMAXGRIP PRMX Catalyst MUST be purchased separately in order to use this product. The required quantity for the application conditions such be purchased accordingly (see below).
Reaction Times and Required amounts of Catalyst
|MMAXGRIP PRMX Primer (at 20˚C, 3% MMAXGRIP PRMX CATALYST)|
|Pot life||10 min.|
|Fully cured||2 hours|
Higher temperatures or greater proportions of catalyst will shorten reaction times, while lower temperatures and smaller proportions of catalyst will extend reaction times. The following table indicates the recommended amount of catalyst required to adjust the curing reaction to the temperature.
|Substrate temperature in°C; required amounts of catalyst in % w/w (guide)|
|MMAXGRIP PRMX Catalyst||6%||6%||4%||4%||2%||2%||2%||2%||1%||1%||1%|
For mixing the product:
- Twin-paddle stirrer
For applying the product:
- Sheepskin Roller
- Brush (only for areas not accessible with roller)
The primer must only be applied to a prepared substrate. Please refer to the appropriate application guide for information about correct surface preparation.
First stir the tub contents thoroughly. Then add the Ennis-Flint MMAXGRIP PRMX CATALYST while stirring the resin at the slow-speed setting and mix for 2 minutes. Make sure the that the product on the base and sides of the container is mixed in. At product temperatures <10˚C the product should be stirred for 4 minutes, as the MMAXGRIP PRMX CATALYST will take longer to dissolve.
Use the sheepskin roller to apply an even film-forming coat of primer. Avoid creating puddles of primer. Once the coating has cured, apply a second coat to cover any defects (bubbles, areas not fully coated).
Preparation for Subsequent Layers
For the subsequent application of Mortar: Once the primer has hardened, apply a second layer and top with a little quartz sand (0.1 – 0.2kg/m² at 0.2 – 0.6mm) while the primer is still wet. The sand topping creates the necessary key. i.e. roughness, for application of the mortar. Never apply the topping to the first coat of primer.
