The following instructions are to help you properly prepare the tube to prevent leaking which will skew your test results:
Short RILEM Tube simulates up to a 60 mph wind-driven rain on the face of the wall
Use the short tube for block only. It may not provide you with adequate pressure for appropriate testing on more dense substrates. This tube is graduated in mph rather than the ml marks that are on the tall tube. There is a protruding lip around the inner opening which aids in getting a good seal with the putty.
Tall RILEM tube simulates up to a 98 mph wind-driven rain
The tall tube may be used on all substrates. The tube is graduated in mililiters, with “0” at the top and representing the 98 mph mark. There is no lip around the inner opening on this tube.
Step 1: Roll the putty into a ball
about 1 and 1/4" in diameter
Step 2: Roll putty between hands to make a tubular shape
About 4" in length???
Step 3: Form tube into a donut shape.
Kneed the seam so that it forms a continuous circle
Step 4: Place the putty around the tube opening, positioning the seam at the top
and press into place
Step 5: Press a thin layer of putty over and into the cylinder opening of the tube
Smooth putty around the opening to create an overlap
While pushing the putty against the base, pinch in an outward manner to form a "pie crust" appearance
Step 6: The resulting outward angle will help prevent the putty from obscuring the opening when attaching the tube to the test area
