Application Instructions

Correct mixing is essential to the performance of Aspartech PRIME. The product is supplied as two pre-weighed components in the exact proportions required for a complete kit.
 

A 5kg kit consists of:

Part ‘A’: 3.480 kg – 69.6%
Part ‘B’: 1.520 kg – 30.4%
 

Do not alter the mixing ratio or split kits unless the individual components can be accurately weighed to the specified ratio.

❶ Preparation
Ensure the correct Part ‘A’ and Part ‘B’ components are available and that all containers are sealed and undamaged. Establish a clean, protected mixing area. Avoid storing or mixing the product in direct sunlight or close to heat sources, as increased material temperature will accelerate the reaction and reduce working time.

​

❷ Premix Part ‘A’
Remove the lid from Part ‘A’ and mix for approximately 60 seconds using a suitable low-speed mixer fitted with a helix mixing paddle.

​

❸ Add Part ‘B’
Pour the complete contents of Part ‘B’ into the Part ‘A’ container, ensuring as much material as practical is transferred.

​

❹ Mix Components
Mix thoroughly for approximately 60 seconds, moving the paddle around the container and across the bottom and sides to ensure a homogeneous mixture.

​

At temperatures below 10°C, viscosity will increase and additional mixing time may be required.

Avoid excessive mixing speeds, which can introduce air into the material.

​

❺ Apply Immediately
Once mixing is complete, immediately transfer the material to a roller tray or distribute it directly onto the prepared substrate.

​

Do not leave mixed Aspartech PRIME standing in the mixing container, as the concentrated mass can generate heat and significantly reduce usable working time.

❻ Apply the Primer
Immediately distribute the mixed Aspartech PRIME over the prepared substrate using a low-pile roller, brush or suitable rubber squeegee followed by back-rolling.

​

Apply as a thin, continuous and uniform film, working the primer thoroughly into the substrate to maximise wetting and penetration.

​

Ensure that no dry or untreated areas remain. Avoid excessive build-up or ponding of material, as unnecessarily high film thickness can adversely affect curing and subsequent coating application.

​

Highly porous or absorbent substrates may require an additional application to achieve complete and uniform sealing.

​

❼ Equipment Cleaning
Tools and application equipment should be cleaned before the material has cured using the recommended Aspartech cleaning solvent. Once cured, the material will generally require mechanical removal.
