Hi Rod,Hey JD,
Have you used the Liquid Rubber? What do you think about it vs regular rubber? cost, install etc. I'm curious as I have no experiece with it.

There are actually 2 products, Liquid Rubber and Liquid Roof. I have used Liquid Roof several times and it is an impressive product. There are situations that this is the only product I will use, such as repairs to EPDM and PVC single ply roofs. This product is excellent on the old "rubber" sheet stuff with proper prep. It would also be an excellent RV roof product, but I don't do that work with my business. I have found that it has better adhesion than acrylic products. Liquid Rubber lays on THICK which should make it a great RV products. You can go with one coat (25 to 30 mil thick) which will wear better on a moving vehicle. It is also meant to be a one coat product which would save on labor.
Now the downside. The cost per SF is high. The can says 42SF per gallon, which may be true on a metal roof without a build up of old sealants and fairly smooth. I got about 10%+ less coverage. At $75 or so a gallon after shipping (5 gallon buckets) the cost is very high. You can save on labor though. Another thing that scares me is that it is incompatible with certain materials. Anything asphalt base is out. Shingles are a given, but this also includes the old Alumaseal products, handyman Henry's fixes, and a host of other products I would imagine. It will also blister off of silicone sealants and hypalon sheets. With these old roofs, sometimes you don't know what you are dealing with for sure. So it seems like a paranoid product.
So under certain circumstances, it is my product of choice. My main liquid roof products are from Ame's Research. This needs to be a multiple coat application, but that allows me to focus on problem areas and does not limit me to number of coats. The combination of the penetrating primer, undercoat materials and top coats allows me to customize the product to the job, existing materials and price range to suit my customer's needs. The gray undercoat is good at ponding situations which is added insurance. The stretch factor is about twice the popular acrylic products. I do prefer the Conklin roof fabric though. It is a spun material rather than woven which is better irregular surfaces.
What liquid roof products do you use?
