Insulated masonry and clay such as Stock Bricks, 140 blocks or maxi bricks. The products look the same as the standard bricks but have an insulating material added to them.

Innofilla is used in conjunction with the mortar mix to add thermal properties to concrete bricks and blocks. It can also be used as a plaster, by mixing 1 bag of Innofilla (100 litres) with one bag of cement.

Introduction:
All the principles of good concrete practice apply to pre-treated Innofilla mixes.

Equipment:

• A mechanical means of mixing is suggested.
• A pan mixer is preferable, as a drum mixer tends to make balls.
• If this equipment is not available, manual mixing with a shovel is acceptable.
• As Innofilla is a vermiculite-based product, water will not be absorbed into the material, The use of a sealed, leak proof container is therefore recommended, to prevent leaching of the required amount of water.

Mixing Instructions:
Mix Innofilla and cement in a drystate first (a little water may be used to dampen slightly, in order to surpress dust).
Add about 20 -30 litres of water to the mix, starting slowly until the right consistency is achieved. The product may appear very dry, especially if hand mixed, but this is correct. It is important to monitor the amount of water added, since small differences in water content may have a large effect on overall consistency and slump
Mix, but do not overdo the mixing time – about 30 seconds in a pan mixer, to prevent too much air.

Yield:
Approximately 11 bags of Innofilla will be required for each cubig meter of plaster to be mixed (cement and water will be added to this quantity of Innofilla). The plaster thickness should be 13-15mm.

Application:
The water-content is very important. Too much air will yield poor results and lead to shrinkage, weak concrete and cracking. Use only amount as indicated.
When plastering, use good conventional plastering techniques. Particular attention should be paid to the degree to which plaster has set, prior to levelling with a straight-edge. As with any plaster, it should be sufficiently so, that it is difficult to cause an indentation by applying thumb pressure. If the straight edge is applied prematurely, it will cause the plaster to de-bond from the wall, and slump cracks will form. Plaster should be applied to a rough surface.
As with any concrete or plaster, proper curing under damp conditions and out of direct sunlight is vital for success.
Once applied, the surface bust be kept moist for the 14 days whilst curing. The product should not be cured quickly, or be exposed to too much sun ‘till cured. Once the plaster is set beyond the Gel State, a straight-edge is used gently to obtain a flat surface.
It is then float finished – first wood with a little water splashed on with a brush, and then by using a steel trowel.
