I have never had that problem with fresh Solartex , but I have with some really old stuff that I bought on RCU.......some did not tack very well and I ended up using thin CA on the seams to keep them in place.

Be careful with this approach because I found that ca screwed with the latex paint........test first in an inconspicuous place before going on to the more visible spots. One good thing with latex is that it is easy to blend in repairs.
