I think I made a huge mistake. I built a working water fountain for a production of Jack Frost. I built the basin with a 3/4" plywood base and and the sides with 1/4" masonite. Everything fits together very tightly. First I caulked the seems and then made what I'm affraid is a huge error. I was going to coat it in Red Gaurd (a liquid latex water proofer used as a water barrier under tile in wet locations) However I was on a budget and at almost $40 /gl, I got the bright idea to use a roof cement tar product for $9 a gallon. Problem is, I applied it a little thick, and after a week, much of it is still not cured. Sticky to the touch. My question's are:
1) will it still hold water if the tar is not fully cured? It is only a two week run and I do not plan on emptying it until strike
2) is the tar going to leech chemicals into the water that will change the water's color?
3) will the above mentioned chemicals cause a problem with my pump? ( a cheap 1/10 hp sumbmersible pump)
4) any ideas to speed the curing process?
5) is it to late to just coat over the tar with a liquid latex or epdm product?
6) can you dim a pump? I already have a T diverting half the water's force back into the basin, but in testing it in a bucket, it was still a little too powerful. And I would love to have proportional control of the pressure through my light board.
Any ideas would be very helpful, tech week starts on Monday!
And on a different note... The fountain is "frozen" the whole show until the end, when the water turns on. I was thinking of hitting it with a light green gel (lee 245) from above, but not sure if it will give me the "spring" effect I'm going for. Thoughts? Thanks
