Professional Black Waterfall Foam 

• This Black Expanding Foam is used to adhere rocks together and to fill the voids under rocks so water does not run under them.  By filling the voids under and behind the rocks especially near waterfalls or elevation drops, the water will be forced to run in front of the rocks not disappearing behind them.  This use of the foam will greatly enhance the look and sounds of your waterfeature!

• Moisture resistant skin prevent water penetration

TJB-INC's Foam Installation Tips:

• When placing a flat rock down to use as as waterfall rock, use a bead of black foam between the liner and the bottom of the rock.  This will seal any small gaps that water might escape under.  The foam when dry, will also "glue" your rock in place.
• Remember, the key word about this black foam is the term "expanding".  A little will go a long way.  If at first (and you will) you apply too much black foam and it starts to come up from between the gaps, do not panic!  You can place gravel on top of the wet foam and hide the ever growing blobs of foam.  Or you can wait 5 minutes until the foam has "skinned" over and then you can safely push down on it and stuff it back into the gaps from where it came from.  BUT...If you touch the foam while it is wet,  ....   it does not come off your skin or clothes!  Learn from what I am telling you.  Your skin, you can clean with a pulmus stone in the shower, but your finger nails will bond with the foam and will eventually grow out after several weeks.  (Been there, done that, many, many times!)  
• If the Black Foam is still wet (within 20 minutes from contact), the new "Black Foam Off Hand Cleaner" is your only hope.
• Do not be turned off by my horror stories.  Black foam is a necessary part of Water Feature Construction.  Wear gloves, and be careful.  The foam will not cause any skin problems, for that it is safe.  It just seems to get everywhere you do not want it to be.
• If you pre-wet the stones and the liner before you apply the foam, the foam will adheare better than if the surfaces are dry.  Not puddles! just moistened will work the best.
• If you have a lot of area to foam or want to save time, I suggest purchasing the Professional Foam Gun Kit or a Foam Gun + ProFoam Can.  It saves on the amount of foam you use, you can stop and start the flow of foam instantly, you can put the gun down and come back later to use it and it won't be all dried up like the DIY foam cans which are single use only.
