Other SIGA Resources:
Exterior Tape: Use Wigluv tape for any exterior application. Its intended for the exterior and includes UV resistance. It's permeability will allow water in the framing to dry through the tape. This helps with cold weather projects where the frame freezes at night since the water can dry through - and not form ice below the tape and "pop" the joint. Wigluv is used to tape sheathing joint, flash window openings since it's available in up to 9" wide, connect the wall sheathing to a slab or stem wall by using Dockskin premier to stick to concrete. It can be used below freezing. When applied on wet walls or frozen surfaces, resist the urge to test it by pulling it off after applying it. When the substrate is still wet or frozen, it can be pulled off. Give it a day to "set" and then try it.
Interior Tape: Use Rissan, Sicral, Corvum for interiors. Rissan is the mainstay with a flexible backing that can both tape flat sheathing joints or wrap toughly around wires and pipe penetrations. It's available in widths up to 6" and easy to apply. Sicral is the paper back tape that is intended for long runs joining interior membrane joints. It has a stiff paper backing that allows it to comes off the straight and be torn by hand.
Tape Dispenser: The Siga dispenser works on all of the Wigluv, Rissan, Sicral 60mm wide tapes and the two Corvum tapes. It's great to be able to carry and cut the tapes with one hand whether you on a ladder or on the ground.
Membranes: Majvest is used for exterior walls. It a very high quality weather resistive barrier. Use Wigluv 60 at the joints and overlaps. Tape any staple penetrations. Majcoat is the heavy roof membrane. It intended to protect vented sheathing layers used in metal or vented assemblies. It is not intended to be used directly under asphalt shingles. Tape joint and staple penetrations with Wigluv 60.
Primur Adhesives: Intended to join membranes to concrete and other materials, the Siga Primur system is one of the only systems that provides an extremely strong, flexible bond that is completely non toxic. It is amazingly sticky and will stick to most building materials. There are two types of Primur: uncured in a sausage or cartridge and the cured "Primur on the roll". The uncured in cartridge or Sausage pack is intended for interior application and will take a day to dry. It's not like most adhesives where you apply it and immediately joint the layers. With Primur, you apply a bead, let it cure, and then join or add the additional material. Once done, the joint is extremely flexible and can move with the building. The cured Primur on the Roll is suitable for exterior joints suck as a Majvest wall membrane to a concrete slab or stem wall. It is pre-cured and the application can be compelled immdeiately. Both primur systems are ideal in crawlspace application to connect a vapor barrier to concrete stem walls.
WOW! STICKY STICKY STICKY! Don't use Siga tape temporarily. It's really hard to get the tape off any surface! don't use it as a plug for door hardware while doing a blower door test, or any other application where you have to remove it on a finish layer. If you need a solvent, try 3M Citrus Cleaner. This tape will give you a new meaning of the term "sticky".
