UltracureTM is a unique silicone emulsion cream for injection into brickwork etc. for the control of rising dampness. UltracureTM can be used on all types of masonry without the use of high pressure equipment. The cream is delivered by hand pressure only from a simple displacement pump and injector lance into a series of holes drilled into the mortar course. From here it migrates rapidly into the masonry pores where the injection cream reverts to a liquid phase and polysiloxanes are formed in situ. During the curing period a low molecular-weight silane vapour is also produced giving excellent migration through the wall. Curing of the DPC starts immediately with the final cure taking 2 - 6 weeks depending on wall thickness.
Extensive field experience with this technology demonstrates that UltracureTM will perform as well as any conventional liquid injection system against rising damp.
Drill 12 mm diameter holes horizontally in the mortar bed at centres no greater than 120mm. The depth of hole required for various sizes of wall is shown in the table below. For walls of intermediate thickness the depth of holes should be pro rata. Where the masonry is irregular, ensure the horizontal drilling pattern targets the base of all perpends of the course selected. Drill hole depth required for walls of various thickness:
|Wall thickness ||115 mm (4.5")||230 mm (9")||345 mm (13.5")||460 mm (18")|
|Depth of hole||100 mm||210 mm||320 mm||430 mm|
|UltracureTM per 10m||0.9 Lt ||1.9 Lt ||2.9 Lt ||3.9 Lt|

* certain types of construction may result in higher retentions, e.g. up to twice the above figures in rubble filled walls. Some allowance should also be made for wastage (ca. 10%).
On external faces of walls drill holes can be re-pointed using a matched mortar or plugged with plastic caps of a suitable size and colour. On internal faces holes can be left open and plaster stopped short of the DPC. It is advisable to leave walls injected with UltracureTM Cream to dry for as long as possible, and for at least 14 days, before removing excess salts and commencing re-plastering.
UltracureTM is not classified as hazardous so is a very low-risk product from a handling point of view. Being a concentrated formulation UltracureTM is supplied in convenient packs which minimises waste. No volatile organic compounds are used in the manufacture of UltracureTM so that hazards and smells associated with evaporating solvents are avoided.
UltracureTM is packed in 3.0 litre plastic pails, 1000ml and 400ml disposable cartridges. Other pack sizes may be available to order. Store in cool, frost-free conditions (temporary exposure to slight frost in transit should not affect usage and stability). Use within 12 months.
