Can or should Geocel 2300 Tripolymer Sealant be used to seal metal panels to eaves and valleys, instead of the typical tape sealant and urethane sealant? Thanks

I do not have personal experience with the product you're mentioning. However, we have used a lot of a different brand product which has the same basic chemistry. This product does adhere well to metal and coatings and it has a good life expectancy, particularly when protected form the weather. However, there are a few limitations: 1) Because the product stays supple, do not expect it to "hold" two pieces of metal together like an adhesive. If the metal pieces are naturally staying together, then it will be fine though. 2) Do not apply to wet or damp surfaces. 4) Do not apply in a bead of less than 3/8" or preferably 1/2". 4) Do not use the product to span over gaps or cavities. It will eventually sink into them and tear when it does. I hope this helps! Todd Miller

I have a sceen-in porch with just a metal roof covering. The condensation is so bad that it is ruining the wood beams. Is there a sealent that can be used to stop this? What can I do to correct this problem? Thank-you, Ada

I really do not know whether this is due to a leak in the roof or due to condensation. If it's condensation, then it is because warm moist air exists beneath the roof and, when the roof gets cold, it condenses. There really is no quick fix to this if it's condensation. I would look for ways to remove any excessive heat or warmth from the porch. Right off hand, I would think the porch would be about the same as outside air so this would not happen. I am really wondering whether there is some extenuating circumstance resulting in warm moist air on the porch???
