How to mix Envirobed HA104 Flowable

Envirobed can be mixed by a forced action mixer or by drill and paddle.

Mechanical Mixing instructions

1. Pour contents of polymer liquid bottle into a wide based mixing vessel such as a Gorilla tub.
2. Add half the bag of UltraCrete Envirobed HA104 Flowable powder and mix with a slow speed forced action mixer (around 300-400rpm) until the powder is absorbed.
3. Add a further quarter of the powder and mix followed by the remaining powder. A total mixing time of 2 minutes should be observed.
4. Check the consistency and add the remainder of the liquid if needed. This allows a change inconsistency without effecting performance.

Drill and paddle mixing instructions

We recommend a grout mixing paddle with a slow speed drill and paddle (around 300-400rpm), using a wide based mixing vessel such as a Gorilla tub. Mix for at least 3 minutes. Note: Insufficient mixing will seriously reduce the performance of the product. Do not add water or part mix.

How to apply Envirobed HA104 Flowable

1. Prior to using Envirobed HA104, internal voids of the frame and brickwork should be dammed with Envirobed CD534 Standard Mortar. This will prevent the HA104 Flowable bedding mortar pouring out into the chamber.
2. Wait until the mortar has stiffened (assess by tapping a hammer into the mortar).
3. Envirobed HA104 Flowable should then be prepared (see mixing instructions above).
4. Application should be within 4 minutes of mixing, by pouring from one side of the pre-levelled frame at a time, working all the way around the frame until it flows and encapsulates the framed flange to a minimum depth of 20mm above the flange.
5. Once the bedding material has reached its initial set, the backfill material UltraCrete QC10 or QC10 F Rapid Strength Concrete can be poured around the frame to fill the void between the mortar edge and vertical trim back.
