I have a crack in my concrete pond. If I coat the pond with this product will it hurt fish? Do you recommend for ponds?
Yes, this product will work as a pond liner (over concrete) or to repair cracks. Once fully dried this should not hurt the livestock of the pond. You may want to go to Inflow Solutions website to get some directions for use and info on the product (MSDS sheet) before using it.
Does this work over wood?
Yes, works great over wood
Can you use silicon caulking over this?
Yes, you can. We also sell a caulk.
Will the product work on the rubber exterior of exposed electrical lines to protect it from UV?
Yes, it will work for that. You will get about 12 to 13 years of UV protection. If you want it to be longer, you can add ceramic topcoat over it.
Does it stick to metal?
Yes, clean and brush off loose rust if any
Would this work on the roof of a pop up trailer?
Yes, it is flexible when applied and will seal around anything.
Would this seal the underside of the osb floor decking on my pop up camper? Would it adhere to the osb or peel off over time?
It will work and it won't peel off over time. Just make sure you don’t have any dirt or dust before you apply.
Will this work on my truck bed?
If you want it to be a barrier protector like a Rhino - then I would not recommend it.
Can this product be used to seal (protect from corrosion) black pipes used for an underground gas line?
The MSDS states that suitable steel must be free from scaling. Your best bet would be to call the vendor directly and ask them (1-866-607-6826). I used the product on exterior grade plywood for a shed roof. Since I just painted a horizontal surface on a slight pitch it worked great, however it's quite liquefied, until it dries and it might be difficult to paint an even layer on a cylindrical pipe.
Will this be flexible enough to work with a folding kayak?
It has 1500% elongation. That means it will expand 15 times the thickness you put down before it breaks. It will recover 90 to 95%.
How long until full cure?
72 hours under normal humidity. Very dry climate can be sooner.
Can I tile on top of this product?
Yes, you can, thinset can be put directly over the Rubberseal™ after its cured.
I have a mobile home with metal roof and would like to know the best product for sealing the entire roof ... 15x70?
Rubberseal™ Roll On (FR-07) would be the best product to use. I would use the black for the first few coats and finish off with the white.
Can this be used on a driveway?
No, it is not suitable for a driveway.
Can I paint a plywood Jon boat with this to seal it?
Yes, you can. Gets stronger over time
Can it be used on a ceramic tile shower?
It’s not a finished product for the surface of the tile. It would be great under the tile to keep the water off the wall board.
My boat roof has an aged EPDM rubber membrane over plywood. Can this be applied directly to the membrane and it adhere ok? Any primer required?
Yes, as long as it is clean. Power wash the EPDM and let it dry before applying Rubberseal™. I think you would get a better application going directly on to the plywood.
Can you paint over it after application to the exterior of a foundation? Or can you apply a foam insulation with finish after applying this?
Yes, you can do both. The only problem will be to use a paint that can take movement. Typically, most paints are fairly rigid and Rubberseal™ is flexible.
The product has now cured and has become tacky. Any suggestions on how to get rid of the tackiness?
Newly coated Rubberseal™ is normally tacky, but as time goes on the tackiness goes away. If you want to get rid of the tackiness quicker, you can use dust or baby powder and put it on the Rubberseal™ and it will get rid of the tackiness.
I am interested in using Rubberseal™ Roll On for use around a leaking skylight. Is the geotextile recommended in this application and how many coats of Rubberseal™ would I need to apply?
Yes, we suggest to use the geotextile for the transition between the skylight and the roof. At 80 mils, it would be a minimum of 4 to 5 coats.
Can Rubberseal™ be used for bathroom waterproofing?
Yes, it can be used for bathroom waterproofing.
