How long does it take to work?

This is probably the most difficult question to answer; the truth is we do not know.

Having re-engineered thousands of units, it is still impossible to estimate how long a unit will take to vent all the surplus moisture out of the unit.

The factors that affect how long it will take are:

1. How much water is trapped in the unit.

2. How big the unit is?

3. How wide the cavity is?

4. The time of the year.

5. The geographical position of the unit.

6. Exposure to solar radiation (sun’s rays).

7. Temperature of internal room.

All of these factors have to be taken into account, what we do know is that some units clear straight away, some units take a few days, and other units take weeks. If the unit has not cleared in 12 Weeks there is usually a problem with the spacer bar sealer.

If you follow our manual carefully a 99% success rate can easily be achieved, in a very few rare cases the spacer bar sealer will not seal the bottom of the unit on its first application, topping up the sealer is all that is normally required to clear the 1% of units that try to resist being re-engineered.
