Notes

Applications

UniPak is a two-component, fast-setting polyester resin mortar. It is particularly suitable for rapid installation and reinstatement in heavily trafficked areas.

Technical

To avoid unnecessary waste, UniPak is supplied as a two component system, which contains 2 equal parts of resin and 2 parts of activator/filler. Always use 1 tin of resin to 1 pack of filler/activator. When laying the material, a minimum thickness of 15 mm and a maximum thickness of 50 mm should be observed. UniPak achieves 60 N/mm² compressive strength in 1 hour and is suitable for rapid bedding applications in accordance with CD 534 installations and in line with the bedding mortar requirements of CC 500 Clause 6.29 to 6.34.

Preparation

All surfaces must be clean, dry and free from loose particles. Any contamination of oil, grease, paint, etc., must be removed prior to application. Always work on a sound and level substrate.

Mixing

UniPak should be mixed thoroughly with a forced action mixer or vigorously by hand with an appropriate tool. Add 1 tin of resin to 1 unit of filler/activator. Pour all the resin from the tin into the outer bucket and slowly add the filler until a homogeneous mix is attained. Mix only enough material to apply in 4 minutes. Do not part mix. Use immediately after mixing.

Placing

The bedding material should be placed on the supporting structure immediately and used within 4 minutes of mixing. The frame should be lowered into position using suitable lifting equipment and placed on the bedding mortar, ensuring it is fully supported. Check that the frame does not overhang the mortar at any point. Care should be taken to prevent voids in the bedding material under the frame, particularly in the vicinity of the cover seating.

Storage

Filler/activator

Store in a dry place at temperatures between 5°-25°C. Avoid frost

Resin

Flammable/combustible. Keep away from oxidisers, heat and flames. Store in tightly closed original container in a dry, cool and well-ventilated place. Keep in original container. Avoid contact with oxidising agents.
