Description

Cocoon is manufactured from pharmaceutical grade filter paper. It features a very high internal surface area with high porosity and purity.

Uses

Cocoon is a poultice medium designed specifically to remove salts associated with rising and lateral damp from masonry walls. It works especially well on sandstone.

Features

  • Clean Application
  •  No detrimental effect to the masonry
  •  Applied by spray or trowel
  •  Premixed, no onsite mixing
  •  Easy removal of salts
  •  Made from non-toxic materials
  •  Cost effective
  •  Fast removal of salts
  •  Low maintenance
 

Technical Data

  • pH                       8 +/- 0.5
  • S.G.                    1.1
  • Application           Trowel or Spray
  • Flashpoint            Non-flammable

Limitations

Cocoon should not be applied to external walls if inclement weather is forecasted before the material dries. This normally takes approximately 4 days at 25 degrees celcius, and 2 days at 30 degrees celcius. If the material is wetted after initial drying, some shrinkage may occur. In this case, the loose material should be removed and new Cocoon applied. Do not apply to surfaces that have free or running water present.

Surface Preparation

Sweep the surface of the masonry to remove any loose sand or salts to provide a reasonably sound surface. Dispose of the material removed from the surface to an appropriate land fill area.

Application

Mask and cover areas if spraying. After preparation, apply one coat of Cocoon by trowel or spray at the rate of 6 to 7kg of mixed material per square metre. This will provide a wet film thickness of approximately 10mm. It is preferable that the surface is left with the textured finish to provide a greater surface area. However, trowelling the surface flat to provide a more even finish can be done without affecting the poultice too much. Leave each application for a minimum of 14 days before removal unless directed otherwise by the manufacturer.

Removal

To remove the Cocoon (normally after 2 to 6 weeks), simply peel from the substrate and dispose of removed material to an appropriate land fill area.

Clean Up

If allowed to dry, the Cocoon will peel off and any residue will wash off with water. Flush machinery thoroughly with clean water after spraying.

Container sizes are:

  • 20  Litre
