    Q:Can this be placed over shingles?

    Answer This Question

    A:  Hi Justme, we don't recommend to use the Lanco Aqua-Proof Primer over shingles, this product is like a liquid rubber. You have to remember that you will loose any warranty that you have on the shingles. With shingles you should have a well ventilated attic if not you can have problems on your roof in the future. With this product your shingles will not be able to breathe and with heat condensation may form. This can cause problems in the future.

      Q:Will it stop leaks around nails in v crimp tin?

      Answer This Question

      A:  Hi Randy, the Lanco Aqua-Proof will work, but for your type of application we would suggest to use the Lanco Aqua-Proof Prep with it's multi use nature makes it ideally suited for a wide variety of applications where a waterproofing solution is needed, such as: to repair cracks and leaks, seal joints and flashings, waterproof under tile and stone and as a waterproofing shower pan liner. You can al so use the Lanco Siliconizer Sealer, which is used for sealing leaks and cracks of all types on any smooth surface. Use around penetrations, flashing and broken tiles. Excellent for repairing expansion joints, containing wall joints, sealing plumbing and electrical intakes.

          A:  Hi Rich, yes you can use the Aqua-Proof Prep to prime metal drip edge for an sbs peel and stick roof material, but to let you know that this product is not a metal primer. It is important to top coat the Aqua-Proof Prep, otherwise it will crack.

            It a great solution for what we needed
            We where having some horrible issues of leaking all over the house and we decided to go with this primer. Ordered it online and picked up at the store, it arrived ahead of time which was great. It applied real easily, gave it two coats and it covered all the micro cracks. Really adhered to the concrete. We then added the Acrylic Urethane Elastomeric White Reflective Roof Sealer from the same brand 24hrs apart and let it cure for 48hrs as described. The following day he had hard rains & 0% leaks.

              As an experienced licensed General Contractor. I can honestly say that all of the Lanco products are outstanding and perform far better than I ever expected. I primarily use a combination of the Aqua-Proof and the Urethanizer to properly seal metal building roofs.
