The importance of good seals in new buildings is noted when walls discolor because of water intrusion; when important papers are soiled, machines get wet and fail, floors and rugs are ruined. Then people think seriously about good sealing practices. Considering the problems and high financial impact that can occur, attention being paid to a good design in sealant joinery is growing.
One of the most reliable ways of eliminating water leakage through the sealant joinery in any building envelope is to apply the rain screen principle within the design, providing pressure equalization, thus preventing the vacuity of water through sealant expansion joints. The basic objective of the Two Staged Sealant System is to provide a major deterrent to water leakage at the outside face of the wall, and seal against air and vapor passage on the interior side of the air space, where the primary seal is exposed to little of the destructive elements of weather and sun.
A Rain Screen Joint Sealant System or Two Stage Sealant System refers to the function of the two beads of sealant as secondary and primary seals in the same joint; preventing water intrusion to the building through the sealed joinery. This system has proven to be an affective way of preventing the vacuity of destructive moisture into the building and its many components. […]
Making sure that your speed dial is set properly for your application is an excellent way to optimize your battery’s life, but it is not the only way. Two other great ways to extend your battery’s life are; remove the battery from your gun when it is not in use and, do not overcharge your battery.The control circuitry on the Albion 14.4V cordless gun energizes as soon as the battery is attached, waiting for the trigger to tell the unit to move. If you store you gun with the battery attached it will slowly drain your battery, wasting the charge and the life of your battery. […]
Whatever your problem, the main thing is to determine the source of the water. This is often very difficult but you may be able to at least isolate the suspect area by judicious water testing. Such tests are essentially static and it is difficult to simulate conditions such as wind driven rain which may be the cause.

The first thing is to try and establish whether the membrane system has failed or whether it is being bypassed. Perhaps a flashing has been missed or the cavity in the brickwork has become blocked or bridged. […]
